Autonomous Computer Interface Daemon
ACID browses, researches, signs in, uses tools, writes and runs code, and delegates work to subagents. It keeps going while you're away — and hands you the wheel the moment you want it.
Starter compute included. No card required.

Agent framework driving a real browser through structured page state.
Vision-driven workflow automation over live websites.
Headless browser API purpose-built for agent workloads.
Minimal browser engine aimed at automation, not humans.
How it works
No model picker. No API keys. No provider setup. You describe an outcome; ACID plans it, opens the tabs, and reports back.
Plain language. "Compare these five suppliers." "Watch this listing and tell me when the price drops."
ACID breaks the job down and spins up subagents, each with its own browser, working in parallel.
Real pages. Real clicks. It reads, scrolls, fills forms, signs in where you've allowed it, and runs code when that's faster.
A report, a dataset, a decision — plus exactly what it cost. Step in and take over at any moment.
Capabilities
Jobs that take minutes or hours don't need you watching. ACID keeps state, recovers from crashes, and picks up where it left off.
One objective becomes many workers, each in an isolated browser, so four sources get read at once instead of one after another.
Sign in once. ACID keeps sessions, cookies and passkeys in an encrypted vault, scoped per site — and never shows secrets to a model.
Watch it work live. Grab the mouse whenever you like, do the tricky bit yourself, and hand control straight back.
The browser is real and it's yours. Pages render locally, in your Chromium profile, not on somebody's scraping farm.
Start a job at your desk, check it from your phone. Same account, same tasks, same balance.
Desktop and mobile
Tasks live on your account, not in a tab you have to keep open. ACID tells you when something needs a human — a verification code, a decision, a paywall — and waits for you instead of guessing.
Everything else, it just finishes.
Compare inference GPU pricing across four vendors
Pricing
No per-task limits. No message caps. No seats. A small job costs very little; a long autonomous investigation costs more, because it did more.
Your balance is in dollars. Running a task draws it down based on the compute the work required — you never have to think in tokens.

Create an account first and your browser activates itself — no keys to copy.
Questions
It depends on how much work it is. Reading a handful of pages and writing a summary is usually a few cents. A long investigation across dozens of sites with several subagents might be a dollar or two. Every task shows its cost when it finishes, and you can see the breakdown any time.
No. ACID handles inference for you and bills it to your credit balance. If you'd rather run your own models — Ollama, LM Studio, vLLM, or any OpenAI-compatible endpoint — you can, under Settings → Advanced → Inference. That's a power-user option, not a requirement.
Yes. ACID is a Chromium browser that runs on your machine with your profile. Pages render locally. You can watch every action, take the controls mid-task, and stop it whenever you want.
ACID finishes anything it can safely finish, saves the task state, and asks you to top up. Nothing is thrown away — add credits and the work continues from where it paused.
Credentials live in an encrypted vault on your machine, scoped to the sites you allow. Secrets are never shown to a model and never leave your device in a prompt. When a site needs a human — a verification code, say — ACID stops and asks you rather than pretending.
They don't expire, and nothing recurring is switched on by default. Optional auto top-up exists for people who want it, and only after they explicitly turn it on.
Autonomous Computer Interface Daemon. It's a daemon in the old sense — a process that quietly gets on with work in the background — that happens to drive a browser.
Create an account, get starter compute, and hand ACID something you'd rather not do yourself.
