Prune

Simple Notes sits at the center of Prune, an AI writing assistant that also ships with a library of AI prompts and a canvas for working through ideas.

Prune is an AI productivity tool for people who want drafting, note taking and prompt help in one place instead of juggling separate apps.

The free plan costs $0 a month and covers basic notes, limited canvas features and basic image generation at 5 images per day, with community support.

That is enough to see whether the workflow suits you, though the image cap is tight if you generate often.

Premium is $20 a month.

It adds unlimited images, advanced image features, the full canvas, advanced AI tools and priority support.

If you mostly write and keep notes, the free tier may be all you need.

If images or the canvas become part of your daily routine, Prune Premium is where the limits come off.
