Google is replacing Gems in the Gemini app with skills. On November 17, 2026, personal accounts for users 18 and older switch over, and the original Gems disappear on December 17, according to Google as reported by gHacks. Existing Gems migrate automatically, but attached files face new limits.

Nov 17: Gems become read-only; skills take over.
Dec 17: old Gems are removed from personal accounts.
Workspace accounts keep Gems until at least March 1, 2027.
Education accounts: not before June 1, 2027.

What is the difference between a Gem and a skill?

A Gem has to be opened on its own. A skill can be called anywhere in Gemini, even mid-chat, by typing a slash and its name (Google plans to move the trigger to the at sign). Skills can also run automatically using a "When to use" section, several can be stacked in one chat, and they follow the open SKILL.md standard, so they can move to platforms like Claude and ChatGPT.

What are the limits on Gemini skills?

Limit	Detail
Active skills	100 at a time
Files per skill	100 MB cap
Sharing	Not possible
Drive and Notebook content	Cannot be added
Unsupported features	Canvas, Deep Research, Guided Learning, video and music creation

Which Gem files will be deleted?

Google will drop the largest files to get under 100 MB and delete unsupported types: legacy Office formats (.doc, .xls, .ppt), compressed archives, GitHub files, and audio or video. Simple text-only Gems should migrate without trouble.

How do I move a Gem manually?

Open Gems in the sidebar and click the pencil next to the Gem.
Download every file under Knowledge.
Go to Customize, Skills, Create, then Create manually.
Paste the Gem's name, description and instructions, then Create.
Add files, or upload a folder with SKILL.md using Replace skill.

Does this affect Workspace users?

Gems move into Settings on November 17 but keep working until at least March 1, 2027. Google has not announced a date for skills in Docs, Sheets, Slides and Studio, nor for under-18 accounts.

Verdict

If you rely on Gems with big knowledge files, back them up before December 17. For more Google AI news, see our Gemini Omni 1.2 Flash guide and the best AI for coding comparison.
