Locus AI

Locus AI has a free plan that covers three documents a day, which is enough to try it on real reading before you pay anything.

Locus AI is an AI search and summarizing tool that pulls answers out of webpages and PDFs, and it runs as a browser extension.

The free tier includes AI helpers and lets you save favorites.

Paid use is called Professional.

It costs $9 a month, or $7.50 a month billed annually at $90.

Both versions remove the document limit and add newer AI models, faster processing and OpenAI integration with unlimited tokens.

You can also choose the role the AI plays.

Trials run 14 days on the monthly plan and 30 days on the annual one.

If you read a lot of PDFs and long pages, the daily cap is the thing to watch on the free plan.
