Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.

AI bookkeeping that keeps receipts, invoices and statements organized automatically
Photograph a receipt, forward it by email to [email protected], or send it through WhatsApp and Telegram. Documents are filed to the right workspace automatically.
The AI identifies each document type and extracts merchant names, dates, amounts, taxes and currencies, covering receipts, invoices and full bank or card statements.
Expenses are sorted into standard categories, and you can add custom categories and rules that ReceiptsAI applies across every document type so reports match your business.
Track monthly spending by category, spot trends and review budgets without building spreadsheets by hand; export to Excel, CSV or PDF when needed.
