Cogent

Say you have a lecture PDF due for an exam on Friday: in Cogent you can chat with that file, turn it into flashcards, then build a practice exam and have your answers checked.

Cogent is an AI flashcard maker and homework helper for students, and it also works as a quiz generator.

The AI can autocomplete flashcards and generate images for them.

The free plan is small.

You get 3 topics, 3 AI flashcards a month, 2 AI exam creations, 3 exam checks and 5 file chats, with no folders.

Sharing is limited to 3 people per file and has no link option.

Elite costs $2.99 a month and removes those caps, adding unlimited folders, autocomplete, image generation and collaborative access.

A feature called File To Study is marked as coming soon.

At that price, Elite is easy to try if you hit the free limits quickly.
