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