Use Case

Custom App Building

Build interactive personal apps like CRMs, trackers, and dashboards by talking to the agent.

The concept

Jetro’s canvas + AI + local compute is a personal app platform. Describe what you want, the agent builds it as interactive frames on your canvas, and you can deploy it as a standalone app with a public URL.

Example apps

YouTube Tracker

Track your favorite creators. Python fetches RSS feeds, frame renders a video grid. Refreshes hourly.

Personal CRM

Log contacts and interactions. Form inputs saved to DuckDB. Searchable, filterable, exportable.

Expense Tracker

Log expenses with categories. Auto-generates spending charts. Monthly summaries and trends.

PDF Research Assistant

Upload PDFs, ask questions. Uses Claude CLI to search documents and answer with citations.

API Monitor

Ping endpoints on a schedule. Track uptime, response times, and status codes. Alert on failures.

Bookmark Manager

Save links with tags. Full-text search. Auto-fetch page titles and descriptions.

How it works

  1. Describe the app to the agent in the chat
  2. Agent builds frames (the UI) + Python scripts (the backend logic) + DuckDB tables (the database)
  3. Preview on canvas, iterate by talking to the agent
  4. When ready, say “deploy this” and the agent packages and starts the app
  5. Access at localhost or via a public URL (paid tier)
