For teams building complex things
Give your team's knowledge a real address.
Turn scattered docs into shared intelligence. MainStreet brings your markdown, research, and decisions into one place your whole team can access — and keeps it synced with your repo.
How it works
Bring it all together
Connect your GitHub repo or start fresh. MainStreet imports your markdown and keeps everything in sync.
Make it accessible
Anyone can read and edit in a rich editor. No markdown syntax, no git commands, no setup required.
Watch it compound
Every edit, comment, and decision builds your team's shared intelligence. AI tools work with real knowledge.
Why MainStreet
From scattered docs to shared intelligence.
One home for everything
Research, specs, decisions, context files — stop scattering them across Google Docs, Notion, and Slack threads. MainStreet gives every piece of knowledge a permanent, versioned address your whole team can find.
Knowledge that compounds
Every edit, comment, and decision adds to what your team knows. The longer you use it, the more valuable it gets.
AI-ready by default
Your AI tools work better when they have real context. MainStreet gives them access to everything your team knows — decisions, research, specs — all in one place.
“We used to lose half of what we knew between meetings. Now it lives somewhere real — and it keeps getting smarter.”
