Shifts the AI assistant from reactive (users ask questions) to proactive (the system surfaces personalized insights automatically). A nightly job analyzes every family's financial data across 7 insight types, writes natural-language explanations via Claude, and surfaces them in a feed on the dashboard and a standalone /insights page. Feature is behind a flag: off by default, enable with INSIGHTS_ENABLED=1 (or via Setting.insights_enabled in the admin UI). Insight types: - spending_anomaly: category spend >25% above/below 3-month rolling average - cash_flow_warning: projected cash balance drops below $500 in 30 days (uses RecurringTransaction + statistical daily baseline) - net_worth_milestone: crossed a round-number milestone or all-time high - subscription_audit: recurring transaction overdue by 45+ days - savings_rate_change: savings rate changed >5 percentage points vs last month - idle_cash: $5k+ sitting in depository account with no activity in 60 days - budget_at_risk / budget_on_track: spending pace vs monthly budget Architecture: - Insight model with dedup_key unique index (upsert, not re-create daily) - Insight::Generator base class + Insight::GeneratorRegistry orchestrator - LLM used as a writer only — financial math runs in pure Ruby - GenerateInsightsJob runs at 6 AM UTC daily via sidekiq-cron - InsightsController with read/dismiss Turbo Stream actions - Dashboard section gated by Current.user.insights_enabled? https://claude.ai/code/session_014vY9xohpm3abSAxVxRF27a

Sure: The personal finance app for everyone
Get involved: Discord • Website • Issues
Important
This repository is a community fork of the now-abandoned Maybe Finance project.
Learn more in their final release doc.
Backstory
The Maybe Finance team spent most of 2021–2022 building a full-featured personal finance and wealth management app. It even included an “Ask an Advisor” feature that connected users with a real CFP/CFA — all included with your subscription.
The business end of things didn't work out, and so they stopped developing the app in mid-2023.
After spending nearly $1 million on development (employees, contractors, data providers, infra, etc.), the team open-sourced the app. Their goal was to let users self-host it for free — and eventually launch a hosted version for a small fee.
They actually did launch that hosted version … briefly.
That also didn’t work out — at least not as a sustainable B2C business — so now here we are: hosting a community-maintained fork to keep the codebase alive and see where this can go next.
Join us!
Hosting Sure
Sure is a fully working personal finance app that can be self hosted with Docker.

Performance Issues
With data-heavy apps, inevitably, there are performance issues. We've set up a public dashboard showing the problematic requests seen on the demo site, along with the stacktraces to help debug them.
