The Flow

One workspace,
three moves.

Stop bouncing between apps. Clex connects preparation and delivery into a single, continuous motion.

01
↓

Drop

Drag files into your workspace. Images, PDFs, documents, anything. No signup, no upload to servers.

02
⚡

Prepare

Compress images, merge PDFs, export PDF pages as images, convert DOCX to PDF, bundle into ZIP. Chain tools together, one after another.

Share

Clex finds the fastest route. Direct P2P when possible, local network for speed, Drive as a fallback. Now with Clex Direct+ — chunk-level verification, ACK/retry, and pause/resume keep the transfer stable on flaky networks.

Vault

The private side
of the same system.

Workspace prepares and delivers files. Vault handles encrypted notes, controlled secret links, and timed Drive handoffs without feeling like a separate app.

Local-First Notes With Trusted Sync

Write encrypted notes, organize them into folders, and keep the primary copy on your own device. When you pair trusted devices, Vault can sync the same notes across them without turning the product into a normal cloud notebook.

Secret Links, QR Handoffs, and Reveal Codes

Set link expiry, choose optional protections like view-once or tab-switch lock, then share the full URL, QR code, or reveal code. The hash key stays in the URL fragment, not on the server.

Drive-Backed Timed Sharing

Sign in with Google Drive, upload into your own Clex Share folder, generate per-file links plus an optional folder handoff, and let Vault delete the session automatically after 24 hours.

Meet Clex Direct+

AirDrop-simple. Torrent-stable. Privacy-first. Direct+ adds chunk-level verification, ACK/retry, pause/resume, and a verified transfer receipt to every direct transfer — without changing the privacy model.

  • Chunk manifestPer-chunk SHA-256 + root hash
  • ACK / retryResends only the failed chunks
  • Pause & resumeMid-transfer, no restart from zero
  • Health scoreLive 0–100 transfer health
  • Verified receiptProof root hash, no file content
  • Cross-device queuePending, active, recent transfers

Older Clex peers stay compatible — Direct+ only turns on when both devices support it. Want to drive transfers from a script or terminal? Read the Developers reference.

Smart Routing

Three paths,
one decision engine.

Clex detects your network, finds the other device, and picks the fastest route — or lets you choose.
