One plan · From $9/month

The AI that builds, browses and gets it done — on your machine.

Cortera plans a task out loud, then actually does it: scaffolds a working app, drives a real browser, writes a real document, or runs on the schedule you gave it — using your own hardware, not a subscription to someone else's.

What it actually does

Not a chat window. An assistant that finishes things.

Six things Cortera genuinely does today — no roadmap items, no "coming soon."

Builds

Turns a sentence into a working app

Describe what you want and Cortera plans it, scaffolds a real server and database, writes the interface, starts it, and checks it in a real browser before calling it done — not a code snippet, a running app.

  • Plans, then builds, then verifies
  • Opens what it built in a browser to check it
  • Dozens of visual styles and layouts to build in

Runs on your machine

Your hardware, not our servers

The model that answers routine requests lives on your machine and stays instant; for something genuinely hard, Cortera automatically brings in a larger model — still local, still yours. Nothing has to leave the building to get an answer.

  • A fast model for routine work, a stronger one for hard problems
  • Switches automatically, no setting to manage
  • Works with the network off

Operates a computer

Uses a browser and your apps like you do

It can open a real website, read the page, click, fill in a form and take a screenshot to prove what happened — and it can drive other apps on your desktop the same way, by actually looking at them.

  • Real browser, real clicks — not a scraped API
  • Reads the screen to find what to click
  • Screenshots every step so nothing is a black box

Writes real documents

Word, Excel and slide decks — actually formatted

Headings, bullet and numbered lists, real tables, a themed header row — a Word document that looks written, not pasted. Slide decks get a real layout, imagery and speaker notes, not a wall of bullet points.

  • Real .docx, .xlsx and .pptx files
  • Dozens of deck styles and layouts
  • Tables that are tables, not text art

Remembers, on its own

"Every morning at 9" is a sentence, not a settings page

Tell it when, in plain language — in twenty minutes, every weekday morning, every Sunday evening — and it runs the request itself and lets you know when it's done.

  • Understands natural time phrases
  • Runs on your machine on schedule
  • A quiet notification when it's done

Speaks

A voice it learned from you, if you want that

Record about eighteen seconds and Cortera can reply in a cloned version of your own voice — or any of its built-in ones — with tone that actually shifts with what it's saying.

  • Voice cloning from a short sample
  • Tone shifts with the content
  • Falls back gracefully with no voice set up

How it works

Three steps, every time.

01

Say what you want

In plain language — build something, find something, write something, schedule something.

02

Watch it work

Cortera plans the steps out loud, then executes them — building, browsing or writing — with the plan visible the whole time.

03

It checks itself

A built app gets opened and tested in a real browser; a scheduled task confirms when it has run. You see the result, not a promise.

Where it's different

Most AI assistants live in a browser tab and think on someone else's servers.

Cortera runs on your own machine, escalating from a fast local model to a stronger one automatically when a request actually needs it — and it doesn't stop at answering. It builds the app, drives the browser, writes the document, or runs the task on your schedule, and shows its work at every step rather than asking you to trust a black box.

Pricing

One plan. Everything included.

Most mainstream AI-assistant subscriptions land around $20/month. Cortera is under half that — one plan, nothing metered.

$9/month

Everything on this page, one plan. No seat tiers, no add-on packs, no usage metering to babysit.

  • App building, verified in a real browser
  • Local model with automatic escalation for hard requests
  • Browser and desktop operation
  • Word, Excel and slide-deck generation
  • Natural-language scheduling
  • Voice, including cloning your own
