Write offline + auto-sync on reconnect
약 3분 소요
Offline writing isn't a degraded fallback — Slima was designed from the start to write smoothly with no network.

What works offline
- ✅ Typing, editing
- ✅ Creating, deleting, renaming files
- ✅ Creating versions (the version system works locally)
- ✅ Viewing version history, restoring
- ✅ Reading all content of the current book
What doesn't work offline
- ❌ AI Coach chat (needs cloud AI)
- ❌ AI chapter analysis, AI Beta Readers
- ❌ Seeing the latest content written on other devices (not synced down yet)
- ❌ Share links (can be created, but recipients can't reach the content)
How auto-sync works
- You write something → saved instantly to local IndexedDB
- With no network → the change enters a pending queue
- Slima detects the network is back → auto-pushes
- Push order follows timestamp + file dependency
Once back online, syncing usually completes quickly.
Seeing what's pending
Activity bar → hover the sync icon → shows "N pending items" + list.
Does a sudden disconnect lose anything?
No. The first of Slima's four protection layers is instant local IndexedDB saving — the moment the network drops, what you wrote is already on your device.

Syncing after a long offline session
Say you wrote for several hours on a plane:
- Land, connect to wifi → auto-sync starts
- Depending on the volume of changes, it may take a while
- The sync doesn't block you from continuing to write — you can upload and edit at the same time
