We have published a free browser sandbox of Localbook, an AI-assisted manual trade journal pilot.
The sandbox starts with four fictional trades. You can add up to three invented records per session to try the entry form, fees, tags and notes. Nothing is saved; reload resets the test. Sandbox import, export and backups are disabled. Use fictional data only.
The separate full downloadable pilot is a standalone HTML file with manual entry, CSV export and JSON backups. It costs $9 once plus applicable tax, through the link on the demo page. One quote currency per book; completed linear trades only. No exchange connection, live prices, trading signals, execution, funding or tax calculations. Records are not encrypted, so keep backups. Local-file storage and mobile behavior have not been independently verified. AI assistance was used for code, layout and English text.

If you already keep a manual journal, what would make this useful to you, and what would prevent you from choosing it over your spreadsheet?
