Encrypted library

Every file, every version — opened right in the browser.

Browse folders, drop files in to upload, and open scans, images, video, PDFs and docs without downloading a thing. The bytes are decrypted on your device, never on our servers.

  • Grid & table views with instant filtering and breadcrumbs
  • Drag-and-drop folder upload with automatic versioning
  • One-click open for 3D scans, maps, media and documents

Messaging

Talk right on the file — not in a separate inbox.

Start a conversation pinned to any file or folder, loop in your team or a group, and share an encrypted attachment inline. Ask QUAIL a question and it answers in the thread.

  • Direct, group, file and folder conversations
  • Live presence, typing and read receipts
  • @QUAIL for instant analysis without leaving chat

File sharing

Share anything — by link or with people — still end-to-end encrypted.

Send a private link that anyone can open (no account needed), or share with specific OWL users. Either way the file’s key never reaches our servers — link shares bake the key into the URL, and people-shares re-encrypt the key to each recipient. Set permissions, an expiry, a password or a QR, and revoke any time.

  • “Anyone with the link” with QR, expiry & optional password
  • Share to people with per-recipient re-encrypted keys & roles
  • Zero-knowledge — revoke access whenever you want

Email sharing

Share a link that looks like a product — not a raw URL.

Copy a branded share card and paste it straight into Gmail, Outlook or Apple Mail. Recipients get a clean preview with a thumbnail, size and an Open in OWL button — the file stays end-to-end encrypted.

  • Three card styles: compact, preview or full details
  • Inline-styled and Gmail-safe — pastes perfectly
  • Live preview before you copy

Log viewer

Drop in any log and read it like a pro.

A virtualized, monospace log viewer with severity colouring, Tx/Rx framing, fast | OR search and span context. Plottable scans unlock charts, and QUAIL’s AI Insights reviews the whole log for you.

  • Millions of lines, virtualized — stays instant
  • Severity filters, Tx/Rx, ± span and charts
  • AI Insights drawer that finds the needle

Self-host & on-prem

Run your own OWL server — on anything, even an air-gapped intranet.

OWL isn’t tied to our cloud. Stand up your own server on Windows, Linux, macOS, a Docker container, a NAS or an ARM box, and keep every byte inside your network. It runs fully offline on an isolated intranet — no outbound connection required — while keeping the same zero-knowledge, end-to-end encryption.

  • Runs on Windows, Linux, macOS, Docker, NAS & ARM
  • Works on air-gapped / intranet-only networks
  • Your server, your keys — zero-knowledge by design
deploy — your-intranet
