Internal tools, without the build

Describe the tool your team needs. It builds and runs it.

Synthonic turns a plain-language description into a real internal app — database, interface, and an AI that operates it — live at a URL from your first message. No React. No Go. No infra.

Every team runs on tools that don't exist yet — the tracker, the intake form, the little CRM. Today that means a backlog no engineer gets to, or a spreadsheet everyone quietly outgrows. Synthonic makes describing it enough.

How it works

Three steps, and you skip all the software.

You talk to a coding agent. The agent writes a small folder of data — not code. Synthonic interprets that folder into a live app and hands an AI the keys to run it.

Describe it

Tell your agent what you need — "a pipeline for my deals," "an intake form for facilities requests." It proposes a concrete first cut, already seeded with example data.

"a CRM for my 30 accounts"

It becomes a real app

Schema, views, permissions, and an AI persona — written as a folder of data. One generic engine turns it into a database and interface. Nobody writes React or Go.

schema · views · policy · instructions

It's live, and an AI runs it

You get a URL from turn one — share the draft, promote to production for coworkers. An AI operates the data through the same app, gated by rules you set.

Why it's different

The app is data — not a codebase you inherit.

Because every app is the same kind of thing — a folder a generic engine reads — building, changing, and operating it stays effortless long after the first version ships.

Live from turn one no localhost

There's no "run it on your machine" step for a non-developer to reason about. You build, it's hosted, here's the link — draft to production on the same folder.

An AI operator, not just a builder /mcp

Every app exposes a governed interface an AI can drive — create, update, read — bounded by a default-deny policy. The tool doesn't just get built by AI; it's run by one.

Changing it is cheap reconcile

Edit the folder, redeploy. Presentation and additive changes are instant; your production data is snapshotted before every change. Iteration doesn't accrue debt.

Solo grows into a team one folder

Start with a tool for yourself. When coworkers should use it too, only auth and who-can-reach-it change — same app, same data, no rebuild.

Live demo

A sales pipeline, running as a folder of data.

The same sales/ folder shown above, deployed and interpreted live — a drag-to-move pipeline, opportunities, and companies, with an AI that can read and update every record.
