Best for AI chat and page summaries inside Chrome
HARPA AI is a Chrome extension that puts chat models on top of the page you have open, summarizing pages, PDFs and YouTube videos and monitoring pages and prices. The free Demo is 10 messages a day, cloud use is metered in Megatokens, and the pricing page showed euros and says no refunds.
Who HARPA AI is for
- 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
Who HARPA AI is not for
- 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

Keep HARPA AI, or make your own?
Keep it
To replace HARPA AI you would be making an AI model, which you can rent by the request but not make. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 57 of the 87 other AI assistants grade higher. It costs $191.71 a year.
What you could not
- An AI model, which you can rent by the request but not make.
- An AI agent, with the models and the safeguards behind it.
- A search engine with an AI model behind it.
- Connections to other products, each kept working as those products change.
What this rests on. HARPA AI’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
