Creating Mini Apps
Describe the tool you want in a channel and Nebula builds it — a one-line prompt is enough to spin up a dashboard, map, form, or simulator.
Mini Apps are small, interactive tools your agent builds inside a channel. You create one by describing it in plain language — no setup, no spec, no separate project.
How to create one
Ask for what you want in the channel you're already in. One sentence is usually enough. Nebula builds the app, drops an icon at the top of the channel, and messages you when it's ready to use.
Score these five apartments with sliders for commute, price, square footage, and neighborhood — I'll paste the numbers.
Built. Your apartment scorer is at the top of this channel. Drag the weight sliders and watch the ranking update — I pre-filled the sample numbers you shared.
Examples
The trick isn't writing a spec. It's saying what you want to see and what you want to do with it.
A dashboard that pulls the numbers together for a specific conversation.
Build me a board-meeting dashboard with revenue by region, a funnel breakdown, and a slider to toggle growth assumptions live.
An interactive map shaped around your actual itinerary, not a generic travel app.
Plan our Japan trip — show the itinerary on an interactive map with our Airbnbs, day trips, and train routes.
A model you can feel, not just a spreadsheet. Sliders, live numbers, break-even lines.
Make a pricing model where I can drag sliders for price, volume, and margin and watch break-even update.
A click-through visualization for a class, a team walkthrough, or a talk.
Turn this into a lesson — an interactive solar system where students click planets to see orbits and compare sizes.

Webhook Triggers
Create webhook triggers in Nebula to start automations from any external service. Receive HTTP POST requests and run workflows automatically.
Using Mini Apps
Every mini app lives in its channel and shows up in the Mini Apps tab — open one alongside the chat or in fullscreen from the sidebar.
