Chai AI
レビューとスコア
4.7/10
A mobile-first character-chat playground with a huge user-made library and a real free tier: fun in short bursts, not built for companionship. Watch the paid structure: $9.99 billed weekly on web, and a 24-hour trial that auto-converts to a $159.99 annual charge.

総評
Chai is best understood as entertainment, not companionship. It's a mobile-first app with a vast user-created character library, ten-million-plus downloads, and a free tier that's genuinely usable. For casual, phone-first character chat with lots of variety, nothing beats it at its price of zero. Live-check reviewing matches that framing: fun in short bursts, falling apart beyond a single sitting. Memory reportedly degrades within a session (on the order of a few dozen messages) and doesn't persist across sessions on the plans most people would use. NSFW is a toggle, but reported behavior is weak and inconsistent, shifting by model and update; Chai is not positioned as an adult product and shouldn't be bought as one. No image generation is confirmed, and while character voices appear in its app-store copy, we haven't assessed any real voice experience; treat it as text-first. The paid structure is our sharpest criticism: on web it's $9.99 per week (north of $40 a month sustained) or $159.99 a year, and the 24-hour free trial auto-converts to the full annual charge; app-store SKUs differ again. Little is documented on privacy either way. As a free toy, Chai is easy to like. As a subscription, it demands unusual care at checkout.
長所
- A genuinely usable free tier on a polished mobile-first app: the lowest-friction way in the category to chat with a variety of characters today.
- Enormous user-created character library (hundreds of thousands of characters) with quick discovery, great for casual variety and short-burst entertainment.
- Real scale and staying power: ten-million-plus downloads and one of the segment's largest revenue bases. An established product, not a fly-by-night.
- No token economy on any surface: paid plans are flat, whatever else we think of their structure.
弱点
- The web paid structure is trap-adjacent: $9.99 billed weekly (over $40/month if sustained), and a 24-hour free trial that auto-converts to the full $159.99 annual charge, both verified on its own pricing page.
- Memory reportedly degrades within a single session (a few dozen messages) and doesn't persist across sessions on standard plans; storylines and 'relationships' reset.
- NSFW is a toggle with reportedly weak, inconsistent behavior that shifts by model and update. Don't buy Chai as an adult product.
- No image generation confirmed, and voice amounts to advertised character voices we haven't assessed: this is a text-first app.
- Little is documented about its privacy posture either way, despite the company's scale.

Chai's pricing needs reading twice. On web (verified from its own pricing page, 2026-05-28): a free tier; a Weekly Plan at $9.99/week (about $43 a month if sustained, the worst-value surface in our guide) and an Annual Plan at $159.99/yr (~$13.33/mo, as the page itself advertises). The sharpest catch: the 24-hour free trial auto-converts to the full $159.99 annual charge, not to a monthly plan; if you try it, cancel-proof your calendar immediately. The iOS app sells a different SKU set entirely (verified from the App Store listing): Premium at $5.99–7.99/week, $13.99/mo, or $134.99/yr, and an Ultra tier at $29.99/mo, so the surface you subscribe on changes both your price and your terms. No token economy on any surface, which we credit. Practical read: the free tier is the product for most people; if you pay, the annual route is the only structure that isn't punitive, and weekly billing should be avoided on principle; it compounds faster than any subscriber tracks.

おすすめな人
The buyer who wants a free, casual, phone-first toy: you're killing time, you enjoy hopping between lots of user-made characters, and you're not trying to build anything lasting with any of them. Chai fits that person almost perfectly (install, chat within a minute, zero cost, huge variety), and that same person is exactly who shouldn't overthink this review. It also fits the curious mainstream user who wants to see what character chat is about without touching an adult product or a credit card. If you do pay, the annual route (~$13.33/mo effective on web) is the only defensible structure, and note that app-store SKUs price differently than the web plans. Go in expecting short-burst entertainment: the fun is real, the variety is real, and the depth isn't.
見送ったほうがいい人
Skip Chai if you're shopping for a companion rather than a toy. Memory reportedly frays within a single sitting and doesn't carry across sessions on the plans most people use, so there is no accumulating relationship here, which is the thing companion buyers are actually paying for. Skip it for NSFW: the toggle exists, but reported behavior is inconsistent and shifts with model updates; adult-content buyers will find the experience unreliable and should use products built for it. Skip it if you want media: no image generation is confirmed, and we haven't assessed any real voice experience. And be careful rather than absent at checkout: the web plan bills $9.99 weekly, which quietly compounds past $40 a month, and the 24-hour trial auto-converts to a $159.99 annual charge. If you test the trial, calendar the cancellation the moment you start it. Anyone paying monthly-competitor prices expecting companion depth is buying the wrong product.
プライバシーと秘匿性
明細にどう表示されるか
Plainly: little is documented about Chai's privacy posture either way. Our research and live checks found no breach, no regulator action, and no researcher warning, but also no affirmative documentation on the questions that matter: chat encryption, retention timelines, training use of conversations, or deletion handling. Chai publishes far less about its data practices than its scale (ten-million-plus downloads and one of the segment's largest revenue bases) would lead you to expect. Two practical notes. First, on mobile, billing runs through Apple or Google, so your statement shows the app store rather than anything conspicuous: incidental discretion, but real. Second, remember what Chai is: a largely user-generated character platform where conversations are the raw material of the product; if the absence of stated policy makes you uneasy, treat chats as non-private and keep identifying details out. Nothing here is an accusation; it's an absence of evidence, stated as exactly that. We haven't field-tested the product or reviewed its policies beyond what our checks could reach.
