A live Tatastu agent session: a plain-language request being turned into a code diff and a passing command, with edits and diffs streamed in real time

03 — Watch it build

It works in front of you

Every edit, command, and search streams live as a clear before-and-after. Nothing happens behind your back. You read it, then you approve it.

04 — The engine

Choose your model

Powered by Claude, the same intelligence behind Claude Code. Switch any time, mid-conversation.

Claude Opus 4.8

Most capable

Anthropic's deepest reasoning model. Reach for it on hard refactors, system architecture, and the gnarly debugging that needs the heaviest lifting. It holds the whole problem in mind.

Claude Sonnet 4.6

05 — What it is

You stay in charge.
The agent does the work.

No syntax to memorize, no terminal to fight. You describe the outcome in plain language. Tatastu shows you the plan, makes the changes in front of you, and waits for your call.

01 Speak it

Say what you want, in your own words

Open a folder, then type or speak a sentence: “add a login page,” “fix the broken checkout.” Tatastu turns plain language into a real plan and real, working code. No commands to memorize, nothing to configure.

The blank canvas. Just start typing.

02 See it build

Watch every move it makes

Edits, commands, searches: everything streams live, right in front of you. Each change lands as a clear before-and-after diff you can read and approve. Nothing happens behind your back. You always know exactly what changed and why.

06 — Made for

Make almost anything

Sites, apps, art, automations, whole stories. If you can describe the project, you can make it. Tatastu is for the people who know what they want to build, not just the people who already know how to code.

  • 01

    Websites

    Landing pages, portfolios, microsites. Go from a sentence to something live people can visit.

  • 02

    Apps & tools

    Dashboards, utilities, little internal tools. Real, working software shaped around what you need.

  • 03

    Automate the busywork

    Scripts that rename, sort, scrape, and glue tasks together. Hand off the repetitive stuff.

  • 04

    Work with your data

    Pull it, clean it, chart it. Turn a spreadsheet or a question into a real, working answer.

  • 05

    Art & visuals

    Generative pieces, posters, covers, interactive visuals. Make something to look at, not just read.

  • 06

    Videos

    Edits, title sequences, motion graphics, generative scenes. Bring a moving picture to life.

  • 07

    Stories & writing

    Worlds, scripts, zines, interactive fiction. Draft, branch, and write something worth reading.

  • 08

    Fix & improve

    Debug it, tidy it, add the feature. Take something that already exists and make it better.

  • 09

    Work on your idea

    That half-formed thing in your head? Tatastu turns it into a real version you can poke at today.
