Overview
4thewords automatically saves a version of your document every 30 minutes while you’re writing. These saved snapshots are called File Versions, a running history of your file that lets you look back at earlier drafts, compare changes, or restore content you’ve edited away. A file you’ve worked on for 5 continuous hours would have up to 10 individual saved File Versions by the end of that session.Where to find it: Open any file → three-dot menu (⋯) on the format bar → Versions Open in 4TW ↗
How Versions Are Saved
- Auto-save every 30 minutes, but only if the file has been modified since the last save and has at least 1 word.
- No empty saves. Versions are not created for empty files or files with no new changes.
- No manual trigger. The 30-minute interval is automatic.
All files created after May 21, 2025 retain at least 1 saved version as a safety net, regardless of your plan or retention period. So you always have at least one recent backup even on a free account.
Regular Versions vs. Pinned Versions
Two kinds of File Versions: Regular versions are auto-saved snapshots. They are kept for a limited time based on your subscription plan, after which they are automatically deleted. Pinned versions are versions you’ve manually marked to keep. Pinned versions are never automatically deleted. They stay as long as you keep them pinned.Plan Limits
| Plan | Retention Period | Pinned Versions |
|---|---|---|
| Free | 30 days | 50 |
| Member | 6 months | 200 |
| Pro | 1 year | 500 |
| Lifetime Pro | 3 years | 1,000 |
Upgrading your plan extends retention for all existing versions. Downgrading does not immediately shorten retention. Versions saved while on a higher-tier plan keep their original expiry dates.
What You Can Do with File Versions
View Version History
Open the File Versions panel for any file to see a list of all saved versions, newest first. Each entry shows the date and time the version was saved, plus its expiration date.Read a Version
Select any version to open a read-only view of the file content at that point in time. Use this to review what the file looked like without making any changes.
Restore a Version
You can restore any version back to an editable state in two ways:- Restore & replace in current file. Overwrites the current file content with the version’s content. The current state is not saved first, so use this carefully.
- Restore in new file. Creates a copy of your file with the version’s content. The copy appears in your file list as a new document. The original file is untouched.
Pin a Version
Click the pin icon on any version to mark it as pinned. Pinned versions won’t be auto-deleted when your retention period expires. Unpin a version to return it to normal. It will then be subject to automatic deletion based on your plan’s retention rules.
The File Versions Modal
The File Versions modal has three tabs:
- This File’s Versions: all versions for the file you’re currently editing
- My Pinned: all versions across all your files that you’ve pinned
- All File Versions, a complete list grouped by file, showing how many versions each file has
Frequently Asked Questions
How often does the system save a version?

What's the difference between pinning a version and restoring it?
What's the difference between pinning a version and restoring it?
Pinning keeps a version from being auto-deleted. The file itself is not changed. Restoring replaces your current file content (or creates a copy) with the content from that version.
Will I lose my current content if I restore a version?
Will I lose my current content if I restore a version?

Your plan drops to a lower tier with a shorter retention period. However, versions saved while on a higher-tier plan keep their original expiry dates. They aren’t immediately deleted.
Can I delete a version manually?
Can I delete a version manually?
Pinned versions can be unpinned, which makes them eligible for automatic deletion. There is no direct manual delete. Unpinning and letting retention handle it is the standard workflow.

Versions only save if the file was modified AND had at least 1 word during that 30-minute window. Check whether you made changes that were actually committed to the file. Also verify you’re looking at the correct file. Each file has its own separate version history.
