A report published Nov. 8, citing Google’s help center, says Gems for adults with personal accounts are scheduled to become read-only on Nov. 17, 2026, then be removed from the Gemini app on Dec. 17, 2026. The first date changes what users can do with their Gems; the second is the reported deadline to download files that do not transfer to Skills. For broader context, see NeoTeo’s earlier coverage of planned changes to GPTs, Gems and Claude Projects.
The two reported Gemini Gems dates
From Nov. 17, adult personal-account users are reported to be able to open Gems for reference, but not use or edit them or create new ones. The report says Google plans to migrate Gems automatically to Skills, a format described as reusable instruction sets that users invoke in a chat by typing a slash and the Skill’s name.
The reported schedule differs by account type:
| Account type | Reported change | Date |
| Adults with personal accounts | Gems become read-only, then are removed from the Gemini app | Nov. 17 and Dec. 17, 2026 |
| Business and nonprofit accounts | Gems remain available through March 2027 | March 2027 |
| Education accounts | Gems remain available through June 2027 | June 2027 |
The Nov. 8 report said Google had not yet announced a timeline for personal accounts belonging to people under 18.
Which files may not move to Skills
The report says compatible files will move with a Gem, but each Skill has a reported total file limit of 100 MB. If the files exceed that limit, the largest are removed first until the remaining total fits.
Reported file types that do not transfer automatically include audio and video, GitHub files, older Microsoft Office files (.doc, .xls and .ppt), and archives such as .zip, .tar and .rar. Files removed to meet the size limit may also need attention.
Check each Gem’s attachments before relying on automatic migration, especially for listed file types or Skills that could exceed 100 MB.
How to save files the migration misses
The report’s described recovery sequence is to open the old Gem and its new Skill side by side, download each file that did not transfer to a device, then upload it to the Skill. It says personal-account users can download missed files until Dec. 17, 2026, when the Gems are scheduled to leave the app.
