OpenRead

Paper Q&A, a related paper graph and LLM translation are the core of OpenRead, an AI research tool for reading and analyzing scientific papers.

You upload PDFs, ask questions about them, chat with its assistant called Oat, or run searches with Answer by Oat and Pro Search.

Paper Espresso and Paper Request round out the toolset.

The free plan is small.

Each of the main features is capped at 5 uses a month, and PDFs are limited to 2MB, though uploads themselves are unlimited.

The $5 monthly Basic plan raises most caps to 300, with 100 Paper Espresso uses and 30 Paper Requests.

At $20 a month, Premium removes the usage limits on every feature.

Universities, institutes and enterprises can take a $200 per seat annual subscription that adds single sign-on, usage insights, larger PDF uploads, priority support, and a default that organizational data is not used for AI training.
