What Is Composite AI?

Composite AI is an automation sidekick that lives right inside the browser you already use. Describe a chore in plain English—“Update my CRM and send the weekly report”—and the agent opens tabs, clicks buttons, types text and ships the work in real time. The magic happens locally on your machine, so there is no hosted cloud browser or scary screen-share tunnel. Everything runs from a small desktop app plus a companion extension, giving you true "autopilot" for web-based busywork. 

Unlike other AI agents that spin up headless servers, Composite AI piggybacks on the active session already logged in to Gmail, LinkedIn, Jira or any other site. That means less fiddling with API keys and zero re-authentication hoops.

Key Features (Why People Are Talking)

Natural-Language Tasking

Simply type or speak what you need. Composite AI parses the instruction, plans a click-by-click route and executes it without additional setup. Recruiters use it to auto-populate applicant-tracking systems, while sales teams pull pipeline data or draft follow-ups at the speed of thought. 

Real-Time Browser Actions

The agent can scroll, copy, paste, select drop-downs and hit submit, all visible in your own tabs. Because it operates in real time, you can watch the cursor move like a “ghost in your machine” and jump in if you ever need to override. 

Local-First privacy

Composite AI runs on-device. No DOM snapshots or credentials leave your computer, easing compliance headaches for security teams. By avoiding cloud rendering, it also dodges common blocks that sites impose on remote browsers. 

Lightning speed

With no round-trip to external servers, actions fire almost instantly. That low latency lets the tool keep working even while you’re screen-sharing on a call, without noticeable lag. 

Integration-Friendly Workflows

Because Composite AI simply drives the sites you already use, it inherits whatever integrations those sites provide. Users routinely chain together LinkedIn → Notion → Slack → Asana handoffs without writing a single line of code. 

macOS-Native Companion App

Today the Workbench desktop app is macOS-only, paired with a small Chrome extension that lets the service take sanctioned actions on page elements. Windows support is on the roadmap, but for now Apple users get the goodies first.

Pricing

Composite AI keeps things simple:

• 30-day free trial with 1,000 model queries so you can stress-test the agent.
• After that, a single paid plan at $20 per month renews the same 1,000 monthly queries.
• A free tier (with tighter limits) remains available for light users or students.

There are no seat minimums, and billing is month-to-month—perfect for side projects or small teams that want to dip a toe before rolling out company-wide. 

FAQ

Is Composite AI safe to use at work?

The tool runs locally and never transmits page content off device, so many IT teams see it as lower risk than cloud RPA bots. Still, you should clear any new automation with your security policies.

Does Composite AI work on Windows?

Not yet. The current release supports macOS (Intel and Apple Silicon). Windows and Linux builds are in development.

How many tasks can I run each month?

You get 1,000 agent queries per month on the $20 plan. If you hit the ceiling, you can either wait for your allowance to refresh or purchase top-up credits.

What happens if a website layout changes?

Composite AI uses a mix of element-recognition heuristics and fallback coordinate clicks. Minor UI tweaks usually self-heal, but major redesigns may require you to re-issue the instruction so the agent can relearn the flow.

Does Composite AI store my passwords?

No. The agent leverages the session already authenticated in your browser; it never extracts or records credentials.

Verdict

Composite AI feels like a quiet workflow partner rather than yet another SaaS dashboard. For $20 a month and zero setup friction, Mac users can offload the grunt work of tab-hopping, form-filling and status syncing to an obedient, local-first browser ghost. If your day is dominated by repetitive web tasks and you crave back some focus time, this might be the browser upgrade you have been waiting for.
