Built for real back offices

One system for everything that lands in the inbox.

Whether it arrives by email, scanner or cloud upload, Epistula treats every document the same way — captured, understood, routed and retained.

✦

Multi-channel ingestion

Scanner drop folders, Gmail filters, IMAP mailboxes, OneDrive, Dropbox, Google Drive, MojERacun, inbound email webhooks — every source lands in the same consumption pipeline.

⚡

AI classification & extraction

Documents are classified, summarized and their fields extracted on arrival. The classifier learns from your corrections, so accuracy improves every week.

⟳

Approval workflows

Configure approval chains per project and document type. Sequential, parallel or any/quorum — with digest emails, reminders and full audit trail.

⌖

Automation rules

Declarative rules: assign projects, tag, notify, move — triggered by correspondent, amount, document type or custom fields. Without writing code.

⛬

Dissemination

Push finished documents to partners via email, Google Drive, OneDrive or Dropbox on the schedule that fits them — daily, weekly or on approval.

🔍

Full-text search

Every document is OCR'd and indexed in MeiliSearch. Find what you need across titles, extracted fields, email bodies and document contents in milliseconds.

🔒

Multi-tenant by design

Every customer gets an isolated database, search index and file storage. No shared state, no accidental cross-tenant reads. Ever.

📱

Mobile inbox

Approve, reject and review documents from iOS and Android. Push notifications for pending approvals — don't let the queue grow while you're travelling.

✉

Inbound email

Give every project a dedicated email address. Forwarded invoices, PDFs from suppliers, receipts — all land tagged and routed automatically.

Sample workflows

Real scenarios, wired end-to-end.
