Build a real app in plain English. Keep changing it safely.
Describe what you need and Lumetis builds a working application with a backend, a database and an interface. Ask for changes the same way. Each change is checked before it goes live, and every version is kept.
Private beta. Free while in beta, with your own AI key.
How it works
Describe it, answer a few questions, open your app. Then keep improving it for as long as you use it.
-
Step 1
Describe it
Write what your app should do, in one sentence or a full page.
-
Step 2
Answer a few questions
When a choice matters, Lumetis asks before it builds.
-
v1 live
Step 3
Open your app
Lumetis builds the backend, the database and the interface, and shows you the decisions it made.
-
v2 live
Step 4
Keep improving it
Ask for changes in plain English. Lumetis checks each one before switching to it, and keeps every version.
Your app will change. Lumetis is built for that.
A change leaves the live version untouched until it has passed its check. Send one and follow it.
-
Your request
Add an expected close date to each deal and show it on the pipeline cards.
-
Understanding your request
It knows your app
Lumetis keeps a model of your whole application: its data, pages, relationships and rules. Each request is handled with everything else in mind.
-
Preparing the change
The request changes that model first.
-
Building the update
The code is regenerated from the model, so the change stays coherent with the rest of the app.
-
Validating the update
Checked before it goes live
Lumetis applies your change, tests the result, and only switches over when it passes.
Nothing breaks silently
If a change fails, the version you have keeps running and you get a clear explanation.
-
Activating the update
The new version becomes the one your app runs on.
-
v5 live
Every version kept
History shows each accepted version and which one is live.
v5 is live. v4 stays in History.
The steps are the ones the product shows while a change runs. The app and its data are an example.
Real software underneath
Every Lumetis app is standard code: a Python and FastAPI backend, a database and a React interface. Each version comes with technical documentation a developer or an auditor can read.
Interface
React,Vite,Tailwind
The pages, forms and navigation people use, wired to the app's own API.
Backend
Python,FastAPI,SQLAlchemy,Pydantic
An API with routes, business rules and validation.
Database
SQLite by default
Tables and relationships designed for what you described.
Documentation for every version
Each accepted version has its own technical documentation, and you can export it as a ZIP. Every app also comes with a README, requirements and package files.
For developersWhat you can build

Your key, your data
Lumetis runs on your own Anthropic or OpenAI key. It's tested when you add it and stored encrypted, and you pay your provider directly for what you use. Your projects are visible only to you.

In research
We're building Lumetis to read an existing application, explain what it does with the evidence behind each conclusion, and plan a change before any code is touched. If your team wants to try it early, talk to us.
- ReadLumetis reads an application it did not build.
- ExplainIt explains what the application does, with the evidence behind each conclusion.
- PlanIt plans the change before any code is touched.
- ApplyThen it applies the change.
Questions, answered plainly
Do I need to know how to code?
No. You describe what you want and ask for changes in plain English. If you do code, you can look at what Lumetis generated and read its technical documentation.
What happens if a change goes wrong?
Lumetis checks every change before switching to it. If the check fails, your current version keeps running and you get a message explaining what happened.
How much does it cost?
Nothing during the beta, apart from your AI provider's usage. Paid plans will come later, and beta users will hear about them first.
Lumetis is in private beta.
