We built Brain for ourselves first.
Brain is made by the team behind Soon, the scheduling app trusted by teams in 60+ countries.
Running Soon, we kept hitting the same wall: decisions got re-discussed, new teammates spent weeks piecing things together, and our AI agents made confident calls on outdated information. Context lived everywhere — Slack, Notion, voice memos, a co-founder's head — and nowhere at the same time.
We wanted one private place that just remembered. That stayed current. That told us what we'd forgotten before a customer did. And that kept our context portable, so we were never locked into one AI tool.
So we built Brain. Soon is tenant zero — every brief, retro, customer call and product decision lives in our Brain too.
— Your team's memory should be on the list too.
What we believe
- Memory is the product. Not features. A team's accumulated context is the most valuable thing they own. We treat it that way.
- Sources beat answers. Every claim Brain makes is anchored to a source you can open. No vibes, no hallucinations.
- Calm by design. We don't notify, badge or nudge. Brain shows up only when it has something worth saying.
- Yours, always. Export as plain markdown. Walk away any time. Privacy is the product.
