Writers & content creators

Turn a collection of ideas into a story.

Gather the fragments, find the thread, and give your story a structure you can move around.

Get the fragments in one place.

Ideas arrive in the wrong order and in the wrong places: a line in a notes app, a source in a browser tab, an image saved to your phone. A Grein board holds all of it, so you can see what you have before deciding what it is.

Add notes, links, images, and audio as they come. Link cards pull in the page title and a preview, so you can tell your sources apart at a glance.

Example board

Outline with pieces you can move.

Make a card for each beat, section, or episode and put them in order. Stack the supporting research with each beat in a composite block, and it moves with the beat when you restructure, instead of being cut and pasted across a forty-page document.

The Story development template gives you a place to start: prompts for logline, theme, and tone, notes on what each character wants and needs, five story beats, and a scene bank for moments you haven’t placed yet.

Example board

Test an angle before you commit to it.

On Pro, the AI creative partner reads what’s on your board and can suggest angles, outline options, or counterarguments as notes you keep or delete. On desktop, you can connect your own Claude or ChatGPT account instead.

The drafting still happens in your writing app. Grein is for the work before and around the draft: the research, the structure, and the notes that keep both within reach.
