Can AI replace Portfolio Coach?
A private dashboard for holdings, family members, projections, and CSV imports is a credible weekend build. Reliable live pricing for UK funds, a ledger-correct Vanguard importer, household data boundaries, maintained tax rules, and AI advice grounded in every account turn the complete product into a multi-day project.
Replacing a paid app means you set it up and keep it running: hosting, updates and backups can be on you. What you give up.

02Could AI build it for you?
The core job: Import or enter family holdings, value them, inspect allocation and projections, then ask an AI for a portfolio review grounded in that data.
What a working version needs:
- Node 22
- OpenAI-compatible API key for AI reviews
- optional market-data API key
- local SQLite database
Submitted by the maker · the complete hosted product is beyond a one-shot local tracker.
03What you'd give up
- reliable live pricing and UK fund symbol mapping
- ledger-backed Vanguard history import
- secure cloud accounts, family sharing, and support access
- maintained UK tax and estate-planning assumptions
- hosted AI reviews with current web context
The core tracker is free to start. Paid AI credits cover the convenient part: a hosted coach already connected to the household's live holdings, while the product maintains pricing, imports, security boundaries, and UK planning logic.
