Which one is for you
Pick Character.AI if
- Fits if you want to chat or call characters made by other users
- Works for people who want to build their own character
Look elsewhere if

- Tight if you stay free: ads, slow mode and no premium chat styles
- Watch out: c.ai+ is shown without a billing period
- Not for you if you want a work assistant, since this is character chat
Pick Pi if
- Fits if you want to talk a decision or a worry through before you act on it
- Works for people who'd rather speak than type, since there's a live voice mode
Look elsewhere if
- Skip it if you need files read, images made or code written, as its listings mention none of them
- Not for you if you want the app in your own language, because the App Store shows English only
- Not for you if you're choosing for a teenager, since the App Store rates it 18+
- Watch out: there's no desktop app, nothing it connects to and no API, so on a computer it's a browser tab
How we grade them
| 2.8GPACharacter.AIGood | 2.8GPAPiGood | |
|---|---|---|
| Value for money | BLite is $4.99 a month, inside the category's cheaper quarter. c.ai+ is $9.99 and its billing period isn't shown. | AIt costs nothing. Pi is listed as free on the App Store and Google Play, and neither listing shows a paid plan or in-app purchase, where the middle of this category wants about $12 a month. |
| Free plan and trial | BFree: unlimited messaging on the free chat styles, with ads and slow mode when busy. One person can live on that. | AFree outright, text chats and the live voice mode alike, on the web, iPhone, iPad and Android. There's no paid tier, so nothing is being held back for one. |
| Features | CText and voice, character creation, chat styles and memory pins on paid plans. A narrow job: character chat. | CIt does its one job fully — conversation, typed or spoken, for decisions, hard talks, learning a topic or practising a language — and that's a smaller job than this category's. The listings mention no file reading, no image making and no coding, and the App Store shows English as the only language. |
| Ease of use | BNo rating on record, but it's an app you install and start chatting in with nothing to set up. | C4.4 from about 2,500 App Store ratings, which is the ordinary middle of this category rather than the top. There's nothing to set up: open it and start typing, or talking. |
| Platforms and integrations | BWeb, iPhone and Android. There's no desktop app or API listed. | CWeb, iPhone, iPad and Android, and no more than that. No desktop app is listed, nothing it connects to, and no API. |
| Best for | chat and voice calls with user-made characters | talking things through, by text or out loud |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
