Your AI builds working apps, with their data, in minutes. You pick the complexity. Start below to learn, play or work.

Talk your app into existence. Watch it grow.

For you, your family, your club.

Tell your AI what you want, in your own words. On the right, your app builds itself while you talk: its page, its data, its look. Change your mind and it changes with it. Say publish and it is live at its own address.

TalkSay what you want, as you would to a person. Your AI asks only when it has to.
WatchThe real page grows beside the chat, one answer at a time. Undo is one sentence.
Publish"Publish it" puts it live at its own address. Keep talking; it keeps growing.

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.

Creator

Describe what you need. Get the model, the data and the app.

For people who build apps and think in models.

Tell your AI what your app is about. It writes the model, fills in sample data and builds the pages, with the rules that keep them right: pay an order and the stock goes down. Then ask to see what's underneath: with Mind Meld on, your AI shows you the model and the data, live.

My shopA real app with its model, rules and data, from one paragraph.

Pro

Spec-first design and building of large apps.

For product managers, analysts and architects, and their teams.

Hand your AI the requirements. It turns them into a spec, a domain model, a design and tests, one feature at a time, and builds the real pages from them. Change a feature and all of it moves together. Guardians check that the app and the tests still match the spec, continuously.

5 minutes
That's the bar!
One feature: spec, model, tests and working pages, kept in step.

Keep in syncChange a feature and every layer moves; guardians catch drift.

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.
