Gemini Gems Are Moving to Skills: Dates, Files and What to Check
Official guidance checked: November 2, 2026. Google says Gemini Gems are moving to Skills. For personal Google accounts belonging to adults aged 18 or older, Gems become read-only on November 17, 2026 and are removed from the Gemini app on December 17. Check your files before the removal date: not every file will transfer. Read Google’s migration guidance.
Which dates apply to you?
| Account | Google’s announced schedule | What to check |
|---|---|---|
| Personal Google account, age 18 or older | November 17, 2026: Gems become read-only; December 17: removed from Gemini | Review instructions and download any files you may need before removal. |
| Personal account under 18 | Google says migration will be announced later | Watch the official guidance for details. |
| Workspace Business, Enterprise, Nonprofit | March 2027 | Check with your organization and confirm the current schedule. |
| Workspace for Education | June 2027 | Check your account and administrator’s guidance. |
Google also says the experimental Gems from Google Labs and Opal will end in November 2026. These are announcements, not proof that every account already has the same interface. Availability and dates can change.
What moves automatically—and what may not
Google says Gems will be recreated as Skills along with supported files when the Gem service ends. Skills have a total file limit of 100 MB. If a Gem exceeds it, larger files are removed until the remaining files fit. Google lists audio, video, GitHub files, older Office formats such as .doc, .xls and .ppt, and archives such as .zip among the unsupported formats. Check the current migration FAQ before relying on the transfer.
- List the Gems and instructions you still need.
- Open each Gem’s knowledge files. Keep an authorized copy of any original you need; personal-account users should do this before December 17, 2026.
- Check file formats and the combined size. Plan a substitute or separate archive for unsupported material.
- After migration, compare each Skill’s instructions and files with your originals. Try a normal case, missing information and a case the assistant should decline or flag.
Do not download, upload or share confidential files unless your organization permits it. Automatic migration is not a substitute for checking access, retention and the result.
Move instructions manually before the automatic migration
Google’s instructions say to open the Gem and copy its name, description and custom instructions. In Gemini, choose Customize → Skills → Create → Create manually, paste those details and create the Skill. Labels can vary by interface and locale.
For knowledge files, Google’s current procedure involves downloading the needed files, downloading the created Skill, placing its instruction file and the documents in a folder named for the Skill, then using the Skill’s replace option to upload the folder. Keep the total under 100 MB and use supported formats. Follow the official step-by-step instructions for the exact naming and current interface. MSL has not performed this migration, so this is documentation-based guidance, not a tested walkthrough.
Skills are not identical to Gems
Skills are reusable instructions that can be invoked in a chat and may be selected automatically when relevant. Google says some functions available with Gems are not yet supported in Skills, including Canvas and Deep Research. File, sharing and connected-app capabilities may evolve. Check the current documentation and your own screen before assuming a workflow will transfer unchanged.
A small test you can reuse
Suppose an old Gem organizes meeting notes. Use fictional input: “The draft is due May 5. The image owner and budget are undecided.” Ask the migrated Skill for decisions, owner, deadline and open questions. The deadline should remain May 5; image owner and budget should stay undecided. If it invents a person or amount, revise the instructions and test again. This is a suggested test, not a measured result.
FAQ
Can I still use my Gem after November 17?
For an adult personal Google account, Google says it becomes read-only on that date: it remains accessible for a time but cannot be used, edited or newly created. Other account types have different schedules.
Will every knowledge file move?
No. The 100 MB total and unsupported formats can prevent files from transferring. Inspect both the original Gem and resulting Skill; retain necessary files with permission.
Do I have to move everything manually?
Google plans automatic migration for Gems and supported files. Manual recreation is an option if you need a Skill sooner. Either way, review the result rather than assuming every capability or file carried over.
