Project Ideas

Actually plausible

Recipe scaler

Paste a recipe, set the number of servings, get scaled quantities. Handles unit conversion (cups to grams) with a small density table.

Meeting cost timer

A timer that shows the running cost of a meeting based on attendee count and average salary. Motivational and horrifying.

Needs research

Local-first notes sync

CRDT-based sync between devices without a server. Yjs or Automerge, storage in IndexedDB, sync over WebRTC. The hard part is conflict UX, not the tech.

Garden planner

Drag-and-drop garden beds, companion planting warnings, frost date lookups by postal code.

Probably absurd

• A dating app for sourdough starters (they need companionship too)
• Regex-as-a-service but every response is also a regex
• A CLI that replaces all your error messages with encouragement

Graveyard

Ideas that were tried and abandoned, kept as a warning:

• RSS-to-podcast converter — text-to-speech was too robotic in 2024, might be worth revisiting now
• Pomodoro Slack status sync — Slack API rate limits killed it
