PocketBook AI
A competent technical user can replicate the core manual-entry + AI-insight experience in a few weeks using existing open-source apps and managed services; the vendor's value is convenience, polish, and bank-linking which are not durable moats here.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All PocketBook AI alternatives, with the arithmetic →
What a replacement has to do
- Manually add transactions, categorize them, view charts/reports, and request AI-generated insights about spending.
What it still won’t have
- Bank account aggregation (Plaid-like automatic bank linking)
- Polish, brand trust, and App Store presence of the commercial app
- Any proprietary AI tuning or analytics pipelines the vendor may run
- Scale-tested infrastructure and multi-user reliability guarantees
What remains hard
- Product polish and ongoing maintenance

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal PocketBook-like iOS app using SwiftUI + Combine and Firebase (Auth + Firestore + Storage). Core features in scope: email/Google sign-in; transaction CRUD with categories, multi-currency support, recurring transaction scheduler; dashboard screens with charts (use Charts framework) for day/week/month/year and category breakdown; server-side receipts validation for App Store subscriptions; integrate an LLM (callable via a small Node/Express proxy) to generate personalized spending insights from the user's recent transactions; offline-first sync with Firestore and basic backup. Out of scope: automated bank account aggregation (Plaid), multi-tenant billing dashboard, and advanced analytics pipelines. Require: input validation, error handling, background sync retry, unit tests for data layer, and basic UI tests for main flows.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
