Isaac

As an AI writing assistant for academic work, Isaac sets itself apart by keeping literature search, document chat and drafting in a single editor.

Isaac is an AI research tool that helps you write papers, find sources, and ask questions of files you upload.

Paraphrasing and summarizing are covered too, so you can go from reading to drafting without switching apps.

The free plan has no subscription and gives you 20 daily tokens for generative AI and chat, plus 100 MB of upload storage.

That is enough to try Isaac, though heavy users will hit the token cap quickly.

The paid plan costs $20 a month, or $16.66 a month billed yearly.

It removes the limits on AI, chat and file storage, adds first draft generation, and swaps community support for premium support.
