Great ideas deserve
to be remembered
Capture, organize, and develop your best thinking — wherever inspiration strikes.
No credit card. Free forever for solo thinkers.
Features
Built for the way ideas actually arrive
Half-formed in the shower. Mid-sentence on a walk. Three at once in a meeting you should be paying attention to. We handle the mess so the good ones don't slip away.
Capture in a blink
Quick-add from anywhere — web, mobile, browser extension, or a single keystroke. Voice notes auto-transcribe.
Cluster, don’t file
Forget folder-trees. Tag freely, link ideas to ideas, and let related thinking surface itself.
Search that gets it
Semantic search finds what you meant, not just what you typed. "That thing about onboarding from March" works.
Co-think with AI
Turn a raw spark into a brief, a counter-argument, or three angles you hadn’t considered. Optional, never pushy.
Spaces for collaborators
Share a project with a teammate, your editor, or a future-you. Permissions are simple and obvious.
Yours, not ours
Export to Markdown anytime. Your data leaves the way it came in. No lock-in, no hostage notes.
How it works
From half-thought to finished thing
Three steps. One habit. A surprising number of ideas you actually follow through on.
Catch the spark
Hit ⌘K from anywhere and dump the thought. No fields, no friction — just text, a voice memo, or a screenshot.
Let it find its people
Idealust suggests related notes, projects, and tags. Accept, ignore, or wander. The graph builds itself.
Ship the idea
Promote a cluster to a project. Outline it, draft it, share it. Then hand the whole bundle to whoever needs it.
Loved by builders
People who used to lose ideas
“I used to have seven note apps and zero notes I could find. Now I have one app and a startup.”
“The semantic search alone earns its keep. It found a sketch from 2024 I’d completely forgotten existed.”
“It feels less like an app and more like a thinking partner who actually remembers.”
Pricing
Free to start. Fair when you grow.
Pay for power, not for permission to use your own ideas.

About
For those who love a good idea
Idealust started in a notebook that got left on a train. Two years of sketches, three half-companies, and one chapter of a novel — gone. We built the thing we wished we'd had.
We're a small team based in Brooklyn and Lisbon. We believe ideas are the currency of a creative life, and that software should be a partner in that work — not another tab to manage.
