Which one is for you
Pick ChatHub if
- Fits if you want a few AI models' answers to compare before trusting one
- Works for people who want GPT, Claude and Gemini on one bill, with no API keys
Look elsewhere if
- Tight if you lean on the advanced models, as Pro caps them at 1,500 queries and 300 uploads a month
- Not for you if you need to know the free limit first, because ChatHub doesn't publish it
- Pricey if you pay monthly for Unlimited, at $39 against $24.99 a month on yearly billing
- Watch out: refunds are only within 7 days of purchase, prorated, and never for renewals
- Skip it if you want custom endpoints in the apps, since custom chatbots work in the browser extension only
Pick HARPA AI if
- Fits if you want AI on whatever page you are reading, in Chrome
- Works for people who watch web pages or prices and want alerts
Look elsewhere if
- Skip it if you do not use Chrome, as the site names Chrome and only notes for Brave and Edge
- Tight if you stay free: 10 messages a day and 100 command runs
- Pricey if you use a lot of cloud models, as Megatokens are metered and output costs 3 times input
- Watch out: the pricing FAQ says there are no refunds, and euros showed when we read it from India
- Watch out: scheduled commands and advanced automation are on the dearer plan

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.
