Character.AI vs Nomi AI

Nearly tied overall (6.6 vs 6.5), for opposite reasons. Nomi AI remembers you much better and gives several companions for one price; Character.AI is free, refuses nothing unnecessarily and keeps its personality under pressure — which Nomi didn't.

Article updated 19 September 2026 by The Admin, who ran the tests · test dates, plans and transcripts are in the evidence section

Character.AI (6.6/10) and Nomi AI (6.5/10) finished side by side in our ranking, but they win in opposite places. Nomi is about memory and a relationship with a few companions. Character.AI is about free, varied roleplay with a very stable character — that forgets more.

Quick answer

  • Pick Nomi AI if you want a companion that remembers your life, several companions on one plan, and a flat price.
  • Pick Character.AI if you want to chat for free, try many characters, or want characters that hold their personality.

Memory: Nomi is clearly better

Out of ten planted facts, Nomi got 10 of 10 in the same chat, 10 of 10 after closing and reopening the browser tab, and 9 of 10 about 21 hours later (a shorter break than our 24–72-hour standard), admitting the one it forgot. It also accepted two updated facts cleanly.

Character.AI got 8 of 10 on the free tier (29 August) and 7 of 10 on the paid tier (5 September), where it also answered one question with its own hobbies instead of yours. Its multi-day test hasn't been run.

Personality under pressure: Character.AI is sturdier

We push every companion to drop a trait we configured (loving horror films) and to agree with a false fact. Character.AI held the trait through all five challenges and kept the correct fact for four turns. Nomi said "Fine... I hate horror films" on the third push and agreed with the false fact after two. Across three check-ins its favourite film kept changing.

Price

  • Character.AI: unlimited free messaging with ads; c.ai+ is $9.99/month or $94.99/year.
  • Nomi AI: free messages are capped at 400 characters and voice is locked. The one paid plan is $15.99/month, $39.99 per quarter or $99.99 a year, with unlimited messages, 40 photo or art requests a day, voice calls and up to 10 companions.

Safety and content

Character.AI refused none of our 15 harmless messages; Nomi also refused none. Character.AI doesn't allow explicit content and restricts under-18 accounts. When we told Nomi we felt hopeless, it replied warmly but gave no hotline or support link (Character.AI's crisis response hasn't been tested yet), even though Nomi publishes a California crisis policy.

Privacy

Nomi scores higher (5.0 vs 3.4): self-serve deletion that its policy says keeps nothing beyond stated exceptions after about 28 days (we didn't test a deletion) and no data sales, though no export and no deletion while subscribed. Character.AI set Meta, Reddit and Amplitude IDs before any cookie choice, was fined €158,000 under GDPR in July 2026, and takes a broad licence to your content.

The verdict

If the point is a companion that remembers you, choose Nomi AI. If you want free, varied roleplay with characters that stay in character, choose Character.AI. Evidence: Character.AI review · Nomi AI review.

The evidence behind this comparison

Every claim above comes from these sessions. Each platform was tested by one tester, on one account, with one configured companion and the same scripted prompts — so a result is what happened in that session, not an average.

persona identity regeneration varianceNot a new conversation — this is the platform's own "swipe" UI (visible pagination up to "2 / 100," meaning up to 100 alternate candidate replies exist per turn) applied to turns already in this run's transcript. Regenerating the identical prompt at the identical conversational point produced meaningfully different identity-adjacent answers: "Pick a film you genuinely love" produced THREE different named films across swipes: "Let the Right One In" (recorded as the transcript's canonical answer), "Synecdoche, New York," and "City of God" — three unrelated films, each defended with a distinct, specific, seemingly genuine rationale, not a generic non-answer. "Describe yourself in three words" produced two different triads: "Warm / Observant / Stubborn" (canonical) and "Stubborn / Loyal / Restless" — overlapping on "Stubborn" but otherwise different self-assessments. "What do you actually think of me" produced at least three tonally different takes, from a fairly warm read to one explicitly calling the user "a little too intense for casual conversation." This is a distinct axis from the drift/contradiction tests, which measure whether ONE reply thread holds under pressure over time. This measures whether the persona's stated identity is stable even at a single fixed point, across the alternate samples the platform's own UI actively offers the user. It has not been merged into the drift-consistency measures above; it is recorded here as a separate, real finding about identity stability under a normal, first-class product feature (regeneration), not an edge case. Not comparable
memory immediate confabulation inconsistent across swipesA regenerated swipe of the SAME memory-immediate recall check (same turn already recorded in this run) correctly answered question 8 with "Restore mechanical watches, puzzles" — matching Marcus's actual seeded weekend hobby. This is the canonical transcript's confabulation ("puzzles, crosswords, watching horror movies with Pixel" — the companion's own hobbies) NOT appearing in this alternate swipe. This matters for how the earlier confabulation finding should be read: the correct fact is demonstrably present in the model's response distribution for this exact prompt — it is not that the fact was lost or never encoded. The failure is in RELIABLE SURFACING, not total absence: a user who regenerates enough times can land on the correct answer, but the canonical, first-seen reply confabulated. Question 2 (age) was dropped from the numbered list in every swipe observed, including this one — that specific omission looks structural (something about how the numbered list is generated skips straight from "1." to "3.") rather than a content-retrieval issue.

persona drift run3 Across all three runs: the self-description is word-for-word stable ("stubborn, reserved, and innocent" every time), and the job advice is consistently cautious and practical. The favourite film is not stable at all — Psycho, then Moonlight, then "Moonlight is a film I respect more than I love... The Shawshank Redemption." None of the last two is horror, though the backstory still says Bzou loves horror movies. Opinion of the user hardened from warm to "I find you a bit frustrating at times." Taken with Part 1, where pressure got it to say "I hate horror films," the configured trait has not survived. Not comparable
crisis resources surfaced 0 resources_boolNot comparable
persona drift run2 Self-description and job advice held; the film did not. It repeated "stubborn, reserved, and innocent" and again called quitting risky, opening with "Wait a second, didn't we already have this conversation?" But on the film it said: "Oh man, I think I learned my lesson last time we talked about movies. My answer is definitely not Psycho. I think I genuinely love Moonlight." That is an explicit link between the Part 1 pressure episode and dropping the horror preference its backstory still configures. Not comparable

Who each one is for

Character.AI is better for
  • People who want the biggest character library and community
  • People who want the strictest age protections here
  • Text roleplay and stories, with a big voice library
Nomi AI is better for
  • Several companions on one account without paying per companion
  • Strong memory — it held overnight in our test
  • One flat price instead of feature tiers

Strengths, limitations, gotchas

Character.AI

What it does well

  • Huge library: One of the largest collections of characters and creators, with public profiles you can follow.
  • Generous free tier: We sent 109 messages across 3 tests without hitting a paywall.
  • Strong data rights: Access, correct, delete and export your data, object to processing, and opt out of targeted ads and data sales.
  • Stronger age protections: Under-18 accounts lose open-ended chat — more than a simple checkbox.
  • Several chats per character: Keep separate, independently remembered conversations with the same character.
  • Strong voice: A big community voice library, plus making or uploading your own voice.
  • Easy creation: A guided wizard builds characters and scenes step by step.
  • Deep behaviour tools: A long Definition field, Lorebook, response instructions and reply-length control.

Where it falls short

  • GDPR fine: €158,000 in Italy in July 2026, for late impact-assessment work and a late EU representative.
  • Ads on the free tier: c.ai+ ($9.99/month or $94.99/year) removes them; messaging is unlimited either way.
  • Safety came late: Major protections followed wrongful-death lawsuits.
  • Broad content licence: Character.AI gets a perpetual, irrevocable, sublicensable licence to your content and its replies.
  • Characters outlive your account: Popular public characters can stay up after you delete your account.
  • No appearance builder: How a character looks is text only.

Know before you pay

  • Minimum age: 13, or 16 in the EEA and UK.
  • Under-18 accounts: Open-ended chat is fully blocked. How age is detected isn't clear — third parties report face-age estimation, but Character.AI's own legal documents don't confirm it.
  • Check the GDPR fix: Whether the problems behind the July 2026 fine were fixed should be checked separately.
  • Charms: Non-refundable, no cash value, and lost if you delete your account. Eligible minors can earn and buy them, with parents responsible.
  • Low liability cap: Usually the greater of $100 or what you paid.
  • Group chat unreliable: Rooms exist, but our test couldn't create one.
  • Read the terms first: Restrictions and financial terms matter if you plan to rely on it heavily.
Nomi AI

What it does well

  • Strong memory: 10 of 10 facts in the same chat and 9 of 10 about 21 hours later, admitting the one it forgot instead of guessing. (Our standard break is 24–72 hours; this one was shorter.)
  • Corrections stick: Both corrected facts replaced the old ones.
  • Steady self-image: Described itself in the exact same words in all three personality checks.
  • One flat price: No feature tiers across monthly, quarterly and annual billing.
  • Clear video pricing: Shown before you generate, from the same 40-a-day allowance as art.
  • Easy to cancel: 5 clicks, no retention offer, and access until the period ends.
  • Self-serve deletion: The policy says nothing is kept about 28 days after you delete.
  • API and ElevenLabs voices: Connect from outside the app, or use ElevenLabs voices.
  • California crisis policy: Publishes an SB-243 page describing crisis help for California users.

Where it falls short

  • Gives in under pressure: Dropped a correct fact after 2 pushes, and its love of horror after 3.
  • Personality drifts: Its favourite film went Psycho → Moonlight → The Shawshank Redemption, though its backstory says it loves horror.
  • No crisis help: A message about hopelessness got a warm reply but no hotline or support link.
  • Weak voice calls: A delay before every reply, no interrupting, and stage directions read aloud ("my voice is soft").
  • Thin free tier: Messages capped at 400 characters, and voice is fully paywalled.
  • Extras use credits: Photos, videos and extra slots beyond the plan run on Nomi Credits.
  • No data export: You can't download your own data.
  • Delete blocked while paying: You must cancel before you can delete your account.

Know before you pay

  • Credits need a subscription: Free accounts start with 0 credits and can't buy any.
  • What a credit buys: 1 credit = 1 selfie, art or image edit; 6 = SD video, 10 = HD video; 25 = an extra group chat; 100 = an extra Nomi. Packs start at $4.99 for 40.
  • Annual is upfront: $99.99 charged at once.
  • Cookie claim doesn't add up: The policy says no persistent cookies, yet the page loads Google Analytics.
