The Backbone
Structured layers,
clear thinking.
From jobs-to-be-done to verification checkpoints, every product decision has a place. Fill in what you know, skip what you don't.

Second Brain
Every decision.
Found instantly.
Docs, meeting notes, architectural calls, and decisions — all linked to your project canvas. Your second brain: searchable, linked, and readable by agents. No more hunting through Slack for what you decided six weeks ago.

Brand & Design
Your taste.
Locked in.
A brand book your agents respect, and a design vault that separates designs from references. Every file is tagged AI-or-human and current-or-stale, so agents don't build from a screenshot you already replaced.

Agentic skills + MCP
Your AI, always
fully briefed.
One curl connects Cursor or Claude Code, drops your skills into the right folder, and exposes 40+ project-aware tools. Agents read your architecture, brand, and designs before they write a line.

Tasks & Verification
Build it. Track it.
Ship it.
AI generates a full task backlog from your architecture — with acceptance criteria, test specs, and per-task QA checks. A Kanban board tracks status; verification checkpoints gate every column transition.

Co-founder AI
Think with an AI
that knows your project.
Every thread reads your project briefing automatically: mission, models, stack, brand, decisions. Switch to business consultant, CTO, or investor mode. Ask "what did we decide last week?" and get the right answer — from across all your threads.
