Character AI Chat - Sign In, Pricing & Mobile App
Character AI is free. No card required to sign up on the web at character.ai or in the official iOS and Android apps. Google, Apple or email login, thirty seconds to a first character reply. The paid tier — c.ai+ at $9.99/month or $94.99/year — removes mid-chat ads, skips Slow Mode during peak hours, extends memory and gives unlimited voice calls. Below: exact signup steps, what c.ai+ actually pays for, which app-store listings are the real ones (id1671705818 on iOS, ai.character.app on Android), how the filter behaves in 2026, and honest comparisons with Janitor AI, Chai, Replika and other alternatives.
What Character AI actually is
Character AI opened public beta in September 2022 and shipped mobile apps in 2023. The catalogue is user-uploaded — over ten million community characters by 2026, sorted by category, tag and public rating. Text is unlimited on both tiers; voice calls work everywhere (three per day on free); Rooms puts several characters into one conversation.
Free tier, no card. In 2026 it runs full-screen ads mid-chat, applies Slow Mode during peak hours, and enforces daily Charms caps on Swipes, Go-ons and Memos. Charms are the in-app currency; top-up packs sell on any tier. c.ai+ costs $9.99/month or $94.99/year (~20% off).
What Character AI is not: an uncensored chat. NSFW mode has never existed, and the filter has grown noticeably stricter since 2023, tightening again after the October 2024 Setzer lawsuit and the November 2024 shift to a 17+ store rating. If you signed up in 2023 and came back in 2026, the app reads as a different product — same brand, materially different behaviour. That is why old Character AI gets thousands of monthly searches; see the section further down for the full breakdown.
In August 2024 Google licensed the underlying technology and hired the founding team back into DeepMind. Character Technologies still runs the app independently under CEO Dominic Perella, so day-to-day product decisions sit with them rather than Google.
Sign in and send your first message
Four steps from opening the site to a first reply.
1. Open character.ai or install the app
Web works in Chrome, Safari, Firefox and Edge. Android: Character AI on Google Play (package ai.character.app). iOS: Character AI: Chat, Talk, Text (id1671705818). Homepage grid loads without an account.
2. Sign in
Options: Google, Apple or email. No phone, no card. Signup asks for date of birth once. Accounts under 18 route onto a teen-tuned model with tighter filters and a Parental Insights hook a parent can link to.
3. Pick a character or open the creator
Sort by trending, category or search. Each card shows a preview greeting, tags, star rating and comment thread. Comments spot good bots faster than star ratings; a card with lively comments beats one at 4.9 stars with three reviews.
4. Chat, add a Persona, decide on c.ai+
Text is unlimited on both tiers. If Slow Mode and mid-chat ads become annoying during evenings, that is when c.ai+ starts paying for itself: priority queue, no ads, longer Chat Memories.
What runs Character AI
The engine is a proprietary model tracing back to Meena and LaMDA work Noam Shazeer and Daniel De Freitas led inside Google before leaving in 2021. No base model has been disclosed and no bring-your-own-key option exists. Character voice holds up well across long sessions — the app's clearest strength since day one. Factual grounding is the weak point: built for roleplay, not search.
Memory sits on separate layers. Session context holds the running chat. Persona is a sheet describing you that a character reads at chat start. Chat Memories, the long-term memory feature, carries state between fresh sessions and works best on c.ai+, where the buffer is longer. A MIT Media Lab and OpenAI study (n≈1,000) found higher daily companion-chat use correlated with more loneliness and lower socialisation.
Character library, categories, and filtering
Over ten million community characters by 2026; the visible surface (cards that see real traffic) is closer to tens of thousands. Discovery sits on category tabs (Anime, Games, Movies & TV, Helpers, Assistants) plus search. The Trending row is editorially reviewed; that is where the best new characters surface first.
Tag filtering is broad. Category yes, MBTI type or hair colour no. Character AI wins on catalogue depth for fan-made versions of specific fictional figures. Star ratings carry less signal than the comment thread underneath, which surfaces filter refusals fast.
Free tier vs c.ai+ side by side
Two tiers. Free covers unlimited text chat with ads, Slow Mode during peak, Charms caps on Swipes, Go-ons and Memos, and three voice calls a day. c.ai+ removes those limits and adds the stack listed below. $9.99/month or $94.99/year, ~20% off annually. No third tier; anything sold as "Character AI Pro" or "Premium" is not the real thing.
| Feature | Free | c.ai+ |
|---|---|---|
| Price | $0 | $9.99/mo · $94.99/yr |
| Text chat | Unlimited | Unlimited |
| Mid-chat ads | Yes | None |
| Peak-hour queue | Slow Mode | Priority — skip Slow Mode |
| Response speed | Standard | Faster |
| Voice calls | 3 per day | Unlimited |
| Chat Memories (long-term) | Basic | Extended |
| Imagine Gallery (image gen) | Not available | Included |
| Access to newest models | Standard | Early access |
| Character definitions | Standard length | Longer |
| 18+ chat styles | Not available | Included (mature framing, not NSFW) |
| Charms caps (Swipes / Go-ons / Memos) | Daily caps | Higher caps + Charms pack bonuses |
| Chat customisation | Basic | Extended |
| c.ai+ badge & community access | — | Included |
What changed in 2026 vs earlier: full-screen mid-chat ads landed on free tier (they weren't there in 2024), and Charms metering on Swipes, Go-ons and Memos tightened. c.ai+ pricing has held at $9.99/month since the 2024 re-scope; the yearly discount landed in 2025. Charms are the in-app currency for Swipes, Go-ons and Memos. Prices verified July 2026. Testing detail on the methodology page.
c.ai+ vs paid tiers across companion apps
- Character AI c.ai+ — $9.99/mo · $94.99/yr
- Kindroid — from $9.99/mo
- PolyBuzz — from $9.99/mo
- Chai Premium — ~$13.99/mo
- Replika Pro — $19.99/mo
- Janitor AI — free interface + BYO API key (per-token pay)
At $9.99, c.ai+ sits at the lower end of the paid range. Only Janitor AI undercuts on flat cost — but shifts spend to per-token API pricing.
Content policy and what "adult" means here
Character AI does not have NSFW mode, and c.ai+ does not unlock one. The paid tier lists "18+ chat styles", which means mature narrative framing (darker themes, adult tone), not explicit content. Steering explicit triggers a filter refusal or a character breaking persona to decline. Romantic and emotionally intimate conversations are allowed; the filter cares about explicit sexual content and graphic violence.
The platform is safe for adults in the usual technical senses. HTTPS, private chats, deletable history, training-data opt-out in settings. Teen safety is the harder question. Common Sense Media's July 2025 survey of 1,060 teens found 72% of US teens 13–17 have used an AI companion. The joint risk assessment with Stanford Medicine's Brainstorm Lab rated the whole category "unacceptable risk" for minors without guardrails.
What the marketing says vs what you get
Four specific gaps between how Character AI is described on paywall pages and how it behaves in daily use.
| Claim | Reality |
|---|---|
| "Free" tier | Free of card and paywall. In 2026 it runs full-screen mid-chat ads, Slow Mode during evening peak, daily Charms caps on Swipes, Go-ons and Memos, and a three-per-day voice call limit. The word carries more caveats than in 2023. |
| c.ai+ "18+ chat styles" | Not an NSFW toggle. Mature narrative framing (darker themes, adult tone) and a small style-picker unlock. Explicit-content refusal behaviour is unchanged from the free tier — the filter treats c.ai+ and free identically on that axis. |
| Ten million+ characters | Catalogue depth is real. The visible surface — cards that see actual traffic — sits closer to tens of thousands, editorially surfaced by the Trending row and the category tabs. Long-tail characters get near-zero discovery without direct link sharing. |
| Character voice fidelity | Strong on tone, weak on facts. Built for roleplay coherence, not accuracy — ask a character something outside its persona and confidently wrong answers land. Not a search or coding assistant. |
Old Character AI vs today
What changed since 2023 and what your options are now.
The 2022–2023 version had a lighter filter, no ads, no Slow Mode, no Charms. Character voice was looser and refusals landed rarely. Three waves tightened it: moderation tuning through 2023, the October 2024 Setzer lawsuit — which drove the introduction of Parental Insights, a separate teen-tuned model, and a noticeable jump in refusal frequency — and the 2026 monetisation shift with full-screen ads and Charms metering on Swipes, Go-ons and Memos.
No setting restores the older behaviour. "Old Character AI" means one of three things. (a) Unrestricted roleplay: closest match is Janitor AI or JanitorAI. (b) Fewer refusals: Chai has a lighter filter on paid tiers. (c) No ads and no queue: c.ai+ buys that without changing the filter. Long-term users sometimes run two accounts, using each for what it does best.
Character creation and the builder
Six fields on the creator: name, avatar, greeting, tagline, description (the pitch users see in the library), and definition (the persona sheet the model reads). Advanced settings add category tags, visibility, and a voice pick from the community voice library. Character quality lives in Definition and Example Dialogue; skimping there produces a bland bot.
Subscribers on c.ai+ get longer character definitions, which matters if you write persona sheets with heavy backstory. TavernAI and SillyTavern card import is not supported: formats are incompatible and no first-party converter exists.
iOS and Android apps, plus what to avoid
Two official mobile clients. iOS: Character AI: Chat, Talk, Text, App Store ID id1671705818, published by Character Technologies Inc. Android: Character AI, Google Play package ai.character.app. Both were rerated to 17+ in November 2024. Sign-in syncs across web, iOS and Android on one account.
Do not install from third-party APK mirrors. "character ai apk" and "character ai mod apk" results point to unofficial sites that ship with adware, credential-stealing overlays, or "filter removed" builds that ship with malware. No legitimate "c.ai+ unlocked" APK exists; subscription state is server-side. If a region blocks the listing, use character.ai in a browser.
Official Character AI community
Links verified against the character.ai footer. Anything else — crypto wallets, "airdrops", knockoff Telegram — is a scam.
Discord
Invite at character.ai/discord. Server carries the Discord verified check. Character sharing, feature requests, event announcements. c.ai+ subscribers get Plus-only channels.
X (Twitter)
@character_ai. Version updates, feature launches, and where any outage confirmation lands first.
r/CharacterAI, around 2.6 million members. Bug reports, filter complaints, character showcases, troubleshooting. Team members occasionally reply.

Character AI alternatives
Right fallback comes down to one call: content freedom, memory, price, or a specific style. The six below come up most on r/CharacterAI when users leave.
| Platform | Category | Best for | NSFW | Library size | Starting price | Trade-off |
|---|---|---|---|---|---|---|
| Janitor AI (also written JanitorAI) | Uncensored roleplay | Open content, big NSFW community | Yes, opt-in | Hundreds of thousands | Free (bring-your-own-key on OpenRouter) | You supply an API key for reliable replies |
| Chai | Casual companion chat | Mobile-first casual chat | Yes, paid tiers | Thousands | Free · Premium from ~$13.99 | Reply quality varies by chosen model |
| Replika | AI companion / girlfriend | Single companion with long-term memory | Yes, Pro only | N/A (one companion) | Free · Pro $19.99/mo | One character, not a library |
| Talkie | Visual character chat | Visual-heavy short chats | Limited | Tens of thousands | Free · in-app purchases | Card-collection loop over deep roleplay |
| PolyBuzz | Anime companion chat | Anime-styled companion chat | Yes, paid | Tens of thousands | Free · from $9.99 | Smaller catalogue than Character AI |
| Kindroid | Personal AI companion | Personal companion, long memory | Yes, paid | Personal characters | From $9.99 | Not built for browsing a public library |
Intent-matching guide: "AI girlfriend"-style single-partner chat → Replika. "Old Character AI" unrestricted roleplay → Janitor AI or JanitorAI. Character AI clone with anime styling → PolyBuzz. Character AI itself remains the deepest public library. Prices verified July 2026. See the about page for how this site positions itself.
When Character AI is slow or throwing errors
Lag during US evenings and European nights is server load, not a fault. In 2026 it surfaces as Slow Mode: replies take longer, mid-chat ads run more between messages, and the queue is visible in the chat header. Waiting five minutes and coming back generally clears it. c.ai+ skips Slow Mode entirely, which is where most of the priority-access value sits for daily users.
A reply that comes back stripped, or a character breaking persona to refuse, is the content filter doing its job. Rephrasing gets the conversation back on track most of the time. If refusals keep landing on the same thread, the chat itself has been flagged — start a fresh one rather than fighting the same session.
Login loops after an iOS update are a common r/CharacterAI report. They clear after wiping Safari-linked cookies via Settings → Safari and re-launching. On Android, Clear Storage on the app forces a fresh sign-in without deleting your chat history, which is stored server-side.
If character.ai returns a 5xx error after a hard refresh, that is a genuine server-side issue. Official confirmation lands on @character_ai on X and on the Help Center at support.character.ai — within a few minutes for anything of scale. Anything shorter than a 5xx is queue-side pressure rather than an outage.
First-message openers
Three patterns that beat "hi". Each anchors the character to a scene before the first reply lands.
- Place-and-moment opener. One line of where you both are and what just happened. "You're closing up the bookshop and I'm the last customer, still browsing." Place, relationship, moment.
- Reference opener. Nod at a detail from the character's persona sheet. "Still angry about what happened at the lake?" The model pulls a thread from the Definition straight into the reply.
- Scene-request opener. Ask the character to set the room. "Look up. Describe what you see, then say something." You get a paragraph of set-dressing to react to.
Testing notes are on the methodology page.
Quick answers to the most searched questions
What is Character AI?
Character AI is a free character-chat platform where you talk to millions of user-made characters in text or voice. Launched September 2022 by ex-Google engineers Noam Shazeer and Daniel De Freitas, it runs at character.ai and as iOS and Android apps. Free tier gives unlimited text; c.ai+ costs $9.99/month for ads-free, priority access.
What is Character AI's official website?
character.ai (short domain, no .com). iOS: Character AI: Chat, Talk, Text on the App Store (id1671705818). Android: Character AI on Google Play, package ai.character.app. This site, character-ai.io, is an independent guide, not the product.
Is Character AI free?
Yes, unlimited text messages with no card. In 2026 the free tier runs full-screen ads mid-chat, puts you into Slow Mode during peak hours, and applies daily Charms caps on Swipes, Go-ons and Memos. Voice calls are capped at three a day. c.ai+ costs $9.99 a month or $94.99 a year and removes those limits.
Is Character AI down right now?
Official status posts go to @character_ai on X and to the Help Center at support.character.ai. Full outages are rare; most of what looks like downtime is queue-side Slow Mode during evening peak hours, a filter refusal on a message, or a stuck login. If character.ai returns a 5xx after a hard refresh, that is a real outage. Otherwise it is regional load or a client-side stall.
Does Character AI have NSFW mode?
No. Character AI runs a strict content filter and does not offer an NSFW toggle on either tier. c.ai+ lists "18+ chat styles", but that means mature narrative framing, not explicit content. The filter has tightened considerably since 2023, which is why users search for old Character AI or move to Janitor AI, JanitorAI or Chai.
Is Character AI safe?
For adults, in the usual technical senses: yes. HTTPS, chats private to your account, deletable history, training-data opt-out. Store rating is 17+ as of November 2024. Common Sense Media and Stanford's Brainstorm Lab rated the social AI companions category unsafe for minors without guardrails; teen use warrants supervision even with Parental Insights on.
Does Character AI have a mobile app?
Yes. iOS: Character AI: Chat, Talk, Text on the App Store (id1671705818). Android: Character AI on Google Play (package ai.character.app). Both sync sign-in with web on one account. Install from official stores only; APK mirrors carry credential-stealing overlays or adware.
How does Character AI's memory work?
Memory sits on separate layers. Session context holds the current chat and works on every tier. Persona is a saved sheet describing you, read at the start of every chat. Chat Memories, the long-term memory feature, carries relationship state, plot beats and established facts between fresh sessions and works best on c.ai+, where the buffer is longer.
Can I use Character AI without signing up?
You can browse the library without an account, but sending a message requires a login. Options are Google, Apple and email. Accounts also unlock Persona, chat history, Rooms and voice calls, so signing in is functionally required after the first browse.
What happened to old Character AI?
Same product name, materially different app. The content filter has tightened in several waves since 2023, most notably after the October 2024 Setzer lawsuit and the November 2024 shift to a 17+ store rating. Users searching for old Character AI mean the pre-tightening behaviour from 2022–2023, which no longer exists on the platform. Closest substitutes today are Janitor AI, JanitorAI and Chai.
What are the alternatives to Character AI?
Janitor AI (open content policy, huge NSFW community), JanitorAI (bring-your-own-key on OpenRouter), Chai (mobile-first, cheap Premium), Replika (single companion, long-term memory), Talkie (visual short chats), Kindroid (personal companion, paid). What fits depends on whether the priority is content freedom, memory, price or style.
Can I get Character AI unblocked at school or work?
Network-level blocks (school Wi-Fi, workplace filters) can only be bypassed by the network admin. Every public workaround (proxy sites, unblocked mirrors, browser tricks) either violates the acceptable-use policy or leaks your login. The safe path is the official mobile app on a personal data connection.
What is c.ai+ and is it worth it?
c.ai+ is the paid tier at $9.99 per month or $94.99 per year — that's roughly a 20% discount for going annual. It removes mid-chat ads, skips Slow Mode during peak hours, speeds up responses, extends Chat Memories so the character remembers more across sessions, unlocks Imagine Gallery for image generation, gives unlimited voice calls, longer character definitions for creators, 18+ chat styles for mature narrative framing, early access to newer models, chat customisation, a c.ai+ badge, and bonus Charms on top-up packs. For anyone using the app daily during US evenings, the subscription earns itself back in avoided queues alone.
Why is Character AI not working?
Usually one of three things is behind it. Server load kicks in during evening peak hours and Slow Mode makes messages take longer. A filter trip means the reply comes back stripped, or a character breaks persona to refuse — rephrase, or start a fresh chat. A stuck login clears after wiping cookies for character.ai in the browser, or Clear Storage on the Android app. Real outages get posted on @character_ai on X within a few minutes.
