Your AI builds working apps, with their data. You pick how fast. Start below to learn, play or work.

Imagine it. Model it. Use it live.

Say what you want to keep track of. Diesel turns it into a model, and the model is already a working app, with your data in it.

  1. 1

    Imagine

    I run a small coffee-gear shop: my products, my customers and their orders, and what's in stock.
    Got it. A customer places orders, each order lists products, and every product has stock in a warehouse.

    In your own words, or talking it through with AI.

  2. 2

    Model

    ✦ drafted by AI places * lines * stock * Customername, email Orderstatus, total Productname, price Stockqty, warehouse

    Drafted by AI from what you said: the things you track and how they link. Change it by talking, or by hand.

    A working app, right away. No code, no screens to design.

Hero

Your own app, with your data behind it.

For you, your family, your club.

Build me an app to track my portfolio: my holdings, what I paid, today's price, and tell me when a company I hold puts out news.

That's all it takes: a working app with lists, pages and alerts, filled with your own data. Change your mind and the app changes with it.

Pick an app to see it. Each one is just a model and your data.

DescribeIn plain words, or talk it through with AI.
UseLists, pages, maps and editors appear right away.
KeepYour data stays yours, and grows with the app.
Creator

Describe a domain. Use the app it becomes, right away.

For people who build apps and think in models.

Create a domain model for a mining company: its properties and claims, the deposits and their resource estimates, drill programs with holes and assays, and who owns what. Seed it with a few sample companies and let me see it.

Model your domain with AI, see it as a graph, and work with live objects the moment a class exists. Sketch draft views, mock APIs by example, then wire behaviour in with rules, flows and streams. Work on a live specification, not an abstract one!

5 minutesFrom a 20-class model to a working, navigable app, with zero code. That's the bar.

Tap a class. Its screens already exist.

/app/Company

Generated from the model. No screens were designed for this.

ModelClasses, keys and references, drafted with AI, editable as text or as a diagram.
RunLists, object pages, maps and editors, live from the model, no build step.
OrchestrateSequential rules for the everyday, flows for parallel steps, streams when you need them.
Pro

Prototype big domains, rules and APIs, fast.

For architects and teams prototyping enterprise-grade domain models and functionality.

Specs and stories live in readable pages, code sits in small strict blocks, and every story is a test. Mock APIs by example, orchestrate with rules and flows, and prove the model before anyone writes production code.

The same portfolio, as source.


    
WriteProse first, with small blocks of rules where they're explained.
MockDescribe an API by example before it exists.
TestStories double as acceptance tests that keep running.

Master

Work at the speed of thought.

  • Set up your team. A designer, a coder, a tester, guardians: each an AI agent with its own role.
  • Point them. Clear directions, then let them go at it through one shared pipeline.
  • Step in any time. Read, approve or send back any spec, design or build between them.

Extras

More ways to live with diesel.

Living notebook

Keep everything you work on with AI in one living notebook.

For you, your hobby, or your small team.

Your chats with AI produce good stuff: plans, answers, lists, little tools. Then it scrolls away. Diesel keeps it, links it, and keeps it fresh, so next week you pick up where you left off.

Works with Obsidian

Prefer writing in Obsidian? Keep writing there.

Your notes and guides can live in your Obsidian vault and in diesel at the same time. Edit on either side, sync, and both stay the same.

  • Two-way sync: changes flow in both directions.
  • Plain markdown files, exactly as they are in diesel. Nothing extra added to your notes.
  • If both sides changed, you get both copies to compare. Nothing is ever overwritten or deleted behind your back.
  • Works on laptops and on the iPad.

Install it in Obsidian with the BRAT plugin: add razie/obsidian-diesel-sync.
