A multiplayer control plane for AI coding agents
Bundle agent sessions, artifacts, and worktrees into a shared Task that your whole team can open, comment on, and collaborate around.
Six phases from clarifying Questions through Research, Design, Structure, and Plan to Implement, each with checkpoints your team can verify before more code is generated.
Inline comments on versioned design docs let humans and agents negotiate the approach in real time, catching architectural mistakes before implementation.
A local daemon runs many sessions in parallel on your laptop, while cloud daemons handle long-running background work that survives closing your machine.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.

The AI coding agent for building ambitious software
Google's agent-first development platform for building and shipping software with AI agents

SpecialistPowerful enterprise-wide search and knowledge discovery across apps, but lacks Notion's flexible doc creation.

The coding agent that learns your coding taste

Free / Open-sourceOpen-source control plane for orchestrating coding agents

Superior block-based typography and mobile note-taking experience, but fewer robust database and automation features.

SpecialistExcellent developer-focused documentation and Git synchronization, but lacks general database and task management.
Built-in AI agents and automated workflows, but less refined document editing interface.

Free / Open-sourceProject management that turns coding agents into real teammates

SpecialistNetworked object-based knowledge management, but less suited for traditional folder hierarchies and task boards.

Stronger relational tables and formula capabilities, but less polished for simple document writing than Notion.
