longest streak — every day since launch
How it started
Built the first version for myself — no sign-up, no database, just a tool shaped around how I work. Used it every day. Friends saw it and wanted the same.
What you get
Weekly planning in 8 min
Describe tasks in plain language, get back structured cards with time slots. No manual sorting or prioritizing.
Journal that actually responds
AI reads patterns across all your entries — not just today's text. Surfaces what you're not seeing.
Habits that compound
Streaks, XP, badges. Progress feels visible and earned — not like willpower grinding every morning.
Psychology mode
Nobody asked for it — users described needing 'somewhere to put this.' It became the most used feature.
Real numbers after launch
100+ registered users
Signed up organically — no ads, no promotion. Just people who saw it and wanted to try.
15 users tracking daily
Not just registered — actively writing entries every day. That's the real retention metric.
15-day longest streak
A user who has logged in every single day since launch. The habit loop works.
−60 min/week recovered
Aggregate across journaling, planning, problem-solving. Over a year — that's 52 hours returned to deep work.
What's under the hood
Claude API — the brain

Supabase — data + auth
Row-level security — each user's journal is fully isolated. Weekly summaries and streak reminders run on schedule.
Next.js + TypeScript
Full-stack app. Server components for data fetching, client components for real-time habit interactions.
Free. No catch.
Forge is free to use — no paywalls, no trial limits, no credit card. Built it for myself, keeping it free for everyone.
