Semantix v0.1 preview·early access is open

The IDE that thinks with you

Semantix turns your codebase into a living graph and puts real agents inside it — they remember, they watch, they ship. Conversations become commits.

The spine

Four decisions we'll never walk back.

Everything in Semantix is built on the same four commitments. They are not features — they are the architecture.

Event-driven

One bus carries everything. The UI is a live view over the stream — nothing polls, everything reacts.

Multi-agent

A lead agent that delegates to specialists. A crew with roles — not a chatbot with a text box.

Local-first

Your code lives on your disk and nowhere else. Agents run stateless against an index you own.

Streaming tools

Watch the agent type files into the graph, token by token. No spinners — you see the work.

What it feels like

A coworker, not a copilot.

Conversations become commits.

Tell the agent what you want in plain language. It reads the graph, edits across files, runs your tests — and hands you a commit while you watch every keystroke land.

  • Multi-file edits, streamed live into the graph
  • Tests run before you're asked to trust anything
  • Full diff on every change — one click to land
you

Make the session auth async — and don't break the CLI.

feat(auth): async session handshake

12 files · +214 −96

A coworker in orbit — not a tool in a drawer.

Semantix agents persist. They remember decisions from last week, notice what you're working on right now, and act between sessions — with a heartbeat you can watch.

  • Long-term memory that survives every restart
  • Awareness of the files and problems you're in
  • Scheduled, autonomous work while you sleep

Your code never leaves the building.

The index is built on your disk. Agents run stateless on top of it. There is no cloud copy of your codebase — nothing can leak what was never sent.

  • Semantic index lives in your project folder
  • Works offline — the graph is yours
  • You decide what any agent is allowed to touch
