ChatGPT
OpenAI's general-purpose AI assistant for chat, images and voice
rabbit OS3
Task-doing AI agent that works from a chat request
Which one is for you
Pick ChatGPT if
- Fits if you want one app for questions, writing help, images and voice
- Works for trying AI without paying, since text chat is free with no cap
Look elsewhere if
- Skip it if you live in Gmail and Docs, where Gemini plugs in and costs less to upgrade
- Pricey if you outgrow Plus: Pro is $100, $200 or $500 a month, and SCIM and role controls need Enterprise, price unpublished
- Watch out: Go at $8 may show ads, and ads have been tested in the free version for US adults since January 2026
- Tight if you upload files, make images or use voice a lot on the free plan, since each one is capped
- Watch out: the Linux app is only a preview for a few distros, and features have gone missing after updates
Pick rabbit OS3 if
- Fits if you want to hand over a whole job, such as research or sorting files, in a sentence
- Makes sense if you already own the rabbit r1 and want it to do more
Look elsewhere if
- Pricey if you use it heavily: the plans jump from $20 to $99 to $199 a month
- Watch out: usage resets every Friday and what you don't use is lost
- Watch out: there's also a five-hour limit, so capacity comes back slowly after a busy stretch
- Tight if you top up: credits are $5 for 250 and need an active plan
- Skip it if you want to see figures first, because the page shows no usage numbers
How we grade them
| 3.4GPAChatGPTVery good | 1.8GPArabbit OS3Weak | |
|---|---|---|
| Value for money | CGo is $8 a month, and OpenAI says that plan may include ads. The one people actually want is Plus at $20, which is where this category's dearest tenth starts, and above it Pro runs $100, $200 or $500 a month. | D$20 a month is the start of the dearest tenth of AI assistants, and the heavier plans are $99 and $199. The page shows only relative usage levels, never a figure. |
| Free plan and trial | BUnlimited text chats. Uploads, images, voice, deep research and memory are in there too, but each comes with a cap you'll meet soon enough. | CFree usage of the rabbit-hosted model plus 30 phone minutes, with no card. The page doesn't say whether it renews, so it may be a one-off. |
| Features | AChat, image generation, real-time voice, web search and Deep Research reports in one app. Custom GPTs, projects, scheduled tasks and Codex, a coding agent, need the $20 Plus plan, and the always-on agent is on Pro. | CTasks, image creation, connected computers, phone calls and a choice of model. The listing shows no usage figures, so what each plan really buys isn't clear. |
| Ease of use | A4.8 from about 11 million App Store ratings. You open it and type a question the way you'd text a friend. There's nothing to set up first. | CNo rating on record, and a computer has to be connected before it can touch your files. |
| Platforms and integrations | AWeb, Mac, Windows, iPhone and Android, with your chats synced across all of them, and a Linux app in preview. There's an API for developers too, and Codex hooks into Slack. | CBrowser, Mac and Windows apps, Telegram messaging and the rabbit r1 device. No phone app is listed. |
| Best for | everyday questions, writing and images | an AI agent that does multi-step jobs from one request |

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.
