I just built Chrysai which allows you to make data apps, browse your data, and chat with your data using a built in chat or connect your own Claude or ChatGPT.
Looking for feedback and validation.

I've had fun trying out different data apps I made. The following was connected with Claude using tools and helped plan a camping trip viewable in the data browser.
EXAMPLE CONVERSATION:
You:
Make a camping app
AI:
The Camping App has been created with the following schema:
Entities:
- trips — title, location, start/end dates, notes, status
- campsites — name, location, rating, amenities, notes, visited flag → links to a trip
- gear — name, category, quantity, condition, notes, owned flag
- checklist_items — name, packed status, category, notes → links to a trip (required) and optionally to a gear item
Suggested prompts included:
- Plan a New Trip
- Gear Inventory Check
- Trip Summary
- Generate Packing List
You: Plan a trip
AI: What kind of camping trip are you planning?
....
(asks a number of questions)
...

The suggested prompts in the example look well-structured already. One thing I noticed building with Claude: the quality gap between a freeform prompt and one broken into typed blocks (role, objective, constraints, output format) is larger than you'd expect.
I built flompt for exactly this, a visual canvas that decomposes prompts into 12 semantic blocks and compiles to Claude-optimized XML. Could be useful for crafting the system prompts behind apps like this. Open-source: github.com/Nyrok/flompt
This sounds interesting, thank you for sharing. This is an area I need to learn about.
