The IDE that thinks with you

Semantix is an AI-first IDE where agents do the work. Schedule it, automate it, compose it from parts, and every agent keeps a memory of its own. Conversations become commits.

Your models

Your keys. Your plans. No middleman.

Bring your own key, your own CLI, or the plan you already pay for.

Paste one API key and a provider's whole model list shows up in the picker — any OpenAI-compatible or Anthropic endpoint, local or hosted. Already paying for Claude or ChatGPT? Your subscription signs in once and the agents run on it. Living in opencode, Copilot or another CLI? Semantix drives it as the agent. Semantix sells the workspace, not the tokens.

  • One key connects a provider, every model it serves
  • Claude Code runs on the subscription you already have
  • opencode, Copilot and other CLIs run as first-class agents
  • No markup on tokens — Semantix never sits in the billing path

Watch your agent work

No spinner. You see the work as it happens.

Nothing staged in these shots: a real session in a real project, captured as it ran. We build Semantix in Semantix the same way.

It looks around first. Then it writes. You watch both.

Ask for a change and the agent's first moves light up the map of your code: every folder it lists, every file it opens, glows on the graph, so you see what it read before it touches anything. Then each file it writes opens as a live diff in the chat while a card on its node types the code in, line by line, with the token count ticking. Nothing hides behind a progress bar.

  • Every read lights a path on the 3D map of your project
  • Writes stream in as diffs, token by token, not as a finished dump
  • Stop it mid-file if it's heading the wrong way

Many agents

Run as many agents as your machine can carry.

One fixing a bug, one writing a feature, one reviewing the last commit, one onboarding to a new repo. All at once, side by side, on the same map of your code.

One window, one agent

Every chat floats as its own window over your code, with its own conversation, its own model and its own work in flight.

Keep them all in view

Minimise one, maximise another, leave the rest working in the corner of your eye. Each window shows what its agent is doing right now.

Your machine sets the limit

There is no agent count to buy. Open as many as your hardware and your model plans can carry.

Task Manager

Work that runs while you're not looking.

Describe it once. Say when it fires.

A chat window only works while you sit in front of it. A task doesn't. Write what you want done the way you'd tell a colleague, pick the project and the agent, and set the clock — every morning, every push, or just once at three.

  • Plain words, not a pipeline config
  • Runs on a schedule, on an event, or on demand
  • The same agent you talk to, with the same memory

Come back and read what happened.

Every run leaves a record you can open: what the agent read, what it changed, what it decided not to touch, and why. Nothing lands in your tree without a trail. If a run got stuck, you see exactly where — and you pick it up from there.

  • A full history for every task, run by run
  • Diffs, commands and reasoning, not just a green tick
  • Stuck runs tell you where, so you never wait in the dark

Agents

Don't chat with an agent. Build one.

The Agent Composer is a canvas. Drop the pieces, wire them together, give them capabilities, press Run. What you draw is what runs.

Draw it

Drop an agent on the canvas. Wire in a trigger, an output, a second agent in parallel or in a loop. The drawing is the program.

Hand it tools

Reading and writing files, searching your code, running the type-checker, running a command. Two clicks each, and the agent has hands.

Press Run, watch it think

Every call streams onto the canvas as it happens. Save the flow, run it again tomorrow, or hand it to a task and let it run on its own.

Memory

The model forgets. Semantix doesn't.

Nothing gets explained twice.

Close the chat, open a new one tomorrow, and it starts where you left off — your stack, your conventions, the reasons behind them. No notes to keep, no context to paste back in, no “as I mentioned before.” You just carry on.

  • A new conversation opens already caught up
  • Knows your stack, your conventions, your reasons
  • Say “remember this” and it does — for good
  • Follows you to your other machine

A mind you can fly through.

Memory belongs to a named agent of yours and goes wherever you let it work. Open the Memory tab and see that mind as a sky of lights — orbit it, search it, open one memory at a time.

  • One agent, one memory, every project you let it into
  • Every memory a light, related ones drift together
  • Off until you turn it on — your call, always

Open a project.
Summon an agent.
Ship.

Free isn't a trial. The whole Studio is $0: the 3D graph, the agent crew, 10 tasks with 15 hours of runs a month, and 1,000 memories across five agents — about three months of heavy use, and nothing you write is ever lost. Your own keys, no card.

Then press ⌘K and say hello.
