Most web tools require cloud accounts, subscription fees, or upload your sensitive financial and document data to remote servers.
PicoAI is built differently:
- 🔒 100% Local-First & Private: Your data never leaves your device's browser memory/IndexedDB.
- ⚡ Instant Access: Zero installation, sign-ups, or framework setup required.
✈️ Offline Capable: Load the page once and run it completely disconnected from the internet.- 💡 Ultra-Lean & Open Source: Clean HTML/JS micro-apps designed for high performance and longevity.
- PicoERP: AI-enabled, offline-first double-entry accounting ERP for shops, societies, and personal finance—books, invoices, inventory, tax, and reporting directly in your browser.
- Mutual Fund Holdings Lite: Consolidated, privacy-first view of your mutual fund portfolio stored local-side.
- Free Accounting System Lite: A lightweight double-entry ledger inspired by GnuCash for personal and small business tracking.
- Inventory ERP Lite: Track orders, supplier relationships, and fulfillment lifecycles locally without complex software setups.
- Mini CTRM Lite: Commodity trading and risk management suite engineered for quick, small-scale local evaluations.
- PicoScan: 100% local, offline OCR and document extraction with zero token limits and zero risk of data exposure.
- Browser PDF Utilities: Merge, process, and manage PDF documents client-side without sending sensitive documents to third-party conversion servers.
Since all applications are pure, client-side HTML, CSS, and Vanilla JavaScript, running the repository locally takes less than a minute.
