Construction sites don't come with reliable Wi-Fi. Basements, remote blocks, regional jobs — the moment you need the drawings, the signal drops. Doclio now works offline, so the set you reviewed yesterday is still on your device today.
What shipped
Save for offline. Pin a whole project with one button. Doclio downloads its drawings, images and annotations to your device and keeps them current whenever you reconnect. Pinned projects show a green ⬇ SAVED OFFLINE badge in the header so you know what's ready.
Per-file pins. Don't need the whole project saved? Open any drawing and click the ⬇ icon in the viewer header. That single file is saved locally, the rest streams as usual.
Install as an app. Doclio is now a full Progressive Web App. On iOS, tap the share icon and "Add to Home Screen". On Android or desktop Chrome, you'll see an install prompt. Launched this way, Doclio runs in its own window — no browser chrome, no tabs to lose, opens in two seconds.
Automatic delta sync. When you come back online, Doclio checks for new drawings or revisions on your pinned projects and quietly downloads the diffs. A small chip in the corner shows progress. No manual refresh, no full re-download.
Passive caching. Every drawing you view while online is automatically cached for 30 days. So even without pinning, the last set you opened is usually still there when signal drops.
What works offline
- View drawings you've pinned or opened while online
- View annotations, comments and attachments
- Review revision history on pinned projects
- Open cached reports
- Navigate between drawings, groups, tags and projects
What doesn't (yet)
Offline mode is read-only and changes are not queued — wait until you have signal before editing. These need a connection:
- Creating or editing annotations
- Posting comments or uploading attachments
- Uploading new drawings
- Approvals
- Using the AI assistant
- Opening drawings you haven't viewed or pinned, and large files (point clouds, videos) unless you marked them to sync
When you reconnect, a red banner drops from the top so you know what hasn't synced.
Storage management
Each pinned project shows a size estimate. A new Offline tab in Settings lists everything you've cached, a storage-usage bar against your device quota, and a one-click "Clear all offline data" button if you ever need to reclaim space. Large files — videos, point clouds, huge CAD exports — are excluded from pins by default to keep things light. You can opt them in per-file if you really need them on the device.
How to try it
- Open any project.
- Click the
⬇ SAVE FOR OFFLINEbutton in the project header. - Go to Settings → Offline and check the green size bar grow.
- Switch your phone to airplane mode and re-open Doclio — it's all there.
Offline Mode works on every Doclio plan. If you have issues, visit docl.io/?kill-sw=1 to reset everything cleanly. You can also contact support to get assistance
