Automate with computer-use agent (ComputerUse / CUA) for macOS, Windows, Linux, Browser, iOS & Android. It sees the screen, clicks, types, browses and writes the code too. One agent, every computer.
Task detail (/task/[id]): title, difficulty, date and time, repeat, category, notes, steps, share toggle, delete
Repeating tasks and daily habits: the database schedules the next one when you finish (overdue habits skip ahead)
Offline: tasks live in IndexedDB with an outbox that syncs when you're back; a service worker keeps screens available
3. AI
One server route, /api/ai: verifies the user, enforces 10 AI actions a day (reset at local midnight), JSON-only model calls
Difficulty scoring: automatic, free, cached by a hash of title + steps; users can no longer set difficulty themselves
Anti-farming: a same-day duplicate scores 1; tasks are rescored at most 5 times
Task breakdown (quick add toggle or task detail): 3–8 steps with minute estimates
Plan my day: time blocks between your wake and wind-down times, a tip in your coach's voice, "Use this plan" sets the times
Gemini Flash first, Groq as fallback, falling through retired model ids; if both fail, difficulty defaults to 2 and actions are refunded
Guardrails: no medical, legal or financial advice, unsafe tasks refused, emails/phones/links stripped before sending
4. Points, streaks and badges
point_events written only by database triggers: 5/10/20/35/50 by AI difficulty, +20% on or before the due date
Anti-cheat: nothing for tasks under 10 minutes old, max 300 task points a day, un-ticking or deleting removes points
Daily streaks with +5 × tier streak points, a freeze earned every 7 days (covers one missed day), undo if the day's only tick is removed
8 badges from the design (6 unlockable now; Rival and Giant Slayer arrive with challenges and the board), with the flip-in "Badge earned" moment
Today: live points with the weekly goal, streak badge (glowing, or dashed "at risk"), real points on finished tasks
Me: total points, best streak, 18-week streak calendar, badge grid
Onboarding
New accounts go through 5 steps from the design: name and username, coach, colour and dark/light, when the day starts, weekly goal; then a WhatsApp invite
Theme previews live; everything saves in one go; "Replay onboarding" on Me
5. Friends
Invite links (/invite/[code], works signed out, joins after sign-in), WhatsApp, share sheet and an on-demand QR code
+100 points each when a new account (under 7 days old) joins with your link, once per person
Username search, friend requests (20 a day), accept/decline/cancel, remove, block (hides you both ways) and report
Other people's data is only reachable through security-definer functions that return public fields
6. Leaderboard
weekly_board(): you and your friends ranked by this week's points (ties share a rank); resets Monday 00:00 local
Board from the design: reset countdown, podium with gold/silver/bronze rings and #1 glow, ranked list, your row pinned when off screen
Live: Realtime on friends' point events (30-second polling fallback); rows glide to new places and arrows flash on rank changes
Today's rank strip ("#3 this week · 45 pts behind Ada"); board beside the app at 1024 px and up
close_weeks() hourly via pg_cron records each finished week and awards Giant Slayer for finishing #1
7. Challenges
Head-to-head: "first to N tasks" (ends the moment someone gets there) or "most points" by an end time (1 hour to 14 days)
Only points earned after the challenge starts count; +50 and the Rival badge for the winner; ties are a draw
Settled by trigger (first to N), when either player opens the app, and every 5 minutes via pg_cron
Board carousel from the design (scores, VS, progress bars, time left, accept/decline/cancel), /challenge/new, and the full-screen trophy moment
8. Feed
Finishing a task marked Shared posts it for your friends (title and points only; notes and steps stay private). Quick add has a Shared/Private toggle; "Share wins by default" lives in Settings → Privacy
🔥 👏 😂 💪 reactions, toggled optimistically
Photo proof from the feed or the task screen: compressed to WebP under 1 MB, stored in the private proofs bucket, +10 points and a verified tick
"Looks sus": two flags put a post's points on hold until the owner adds a photo
/api/cron/cleanup-proofs runs daily (vercel.json) and deletes photos older than 7 days; the tick and points stay
9. Coach and nudges
Tap a friend on the board (or "Nudge back" on the feed) to nudge them: four preset lines, or one the AI writes in your coach's voice (1 AI action)
3 nudges per friend per day, friends only, max 120 characters (send_nudge)
Nudges you receive: a toast with the sender's avatar shaking, a dot on the Feed tab, and a strip at the top of the feed
From 6 pm, the coach bubble on Today becomes an AI recap of your day (written once per day, saved in coach_recaps); the static lines are the fallback
10. Notifications
Web push for nudges, challenge invites/accepts/results, friend requests/accepts, the Monday result (9 am) and "streak at risk" (8 pm, via pg_cron)
Max 5 a day, held back during your sleep hours, and each kind can be switched off (Settings → Notifications); a one-time "Turn on" card on Today
Queued in the database (push_queue), sent by /api/push/flush: right after the action, when anyone opens the app, and every minute from Supabase (supabase/push-schedule.sql)
Dead devices are removed automatically; on iPhone, push works once Rivl is added to the Home Screen
11. Focus timer and weekly recap
/focus: a 25-minute session timed by the server (+5 when it ends, up to 8 a day), from a task, its options, or the Me screen; keeps the screen awake, corrects for a phone clock that's off, and pays out even if you're on another screen (timer pill and toast)
/recap: the 1080 × 1920 card from the design (rank, points, streak, top task, your theme and accent), drawn as a PNG by /api/recap/card; share straight to WhatsApp Status or Instagram Stories with your invite link, or download it
Private top tasks stay off the card unless you switch them on; Monday's result push opens the recap
Next: polish and launch (step 12).
Getting started
Create a Supabase project and run each file in supabase/migrations/ in order (SQL editor, or supabase db push). If you're not sure which have run, paste supabase/catch-up.sql into the SQL editor instead: it applies everything that's missing and is safe to run any number of times. Regenerate it after adding a migration.
In Supabase → Authentication:
URL configuration: set the Site URL and add http://localhost:3000/auth/callback and your production https://…/auth/callback to the redirect URLs.
Providers: enable Email. Google is optional for now: enable it in Supabase, then set NEXT_PUBLIC_GOOGLE_AUTH_ENABLED=true to show the button.
cp .env.example .env.local and fill in the project URL and publishable key, plus SUPABASE_SECRET_KEY and GEMINI_API_KEY (and optionally GROQ_API_KEY) for AI, CRON_SECRET (any long random string) for the daily photo cleanup and push schedule, and the VAPID keys for push (npx web-push generate-vapid-keys). After deploying, fill in and run supabase/push-schedule.sql once. In Vercel, add the same as environment variables.
npm install, then npm run dev.
/ and /brand work without Supabase; sign-in shows a setup note until the env vars are set.
Theme system
Tokens live in app/globals.css as CSS variables, switched by data-theme and data-accent on <html>. An inline script in app/layout.tsx applies the saved cookie before first paint. The profile is the source of truth across devices (components/theme-sync.tsx).

Accent-coloured text in dark mode uses each accent's base hex, except Nova, which uses #AE7BFF: base Nova is only 3.9:1 in a coach bubble and 4.2:1 on surface-2.
