Google is replacing Gems, the custom versions of Gemini that people set up with their own instructions, with a newer feature called skills. A notice in the Gems manager in the Gemini app says the switch starts on November 17, 2026, 9to5Google first reported.

What Google says

The banner in Gemini’s Gems manager reads: “Gems will become skills starting Nov 17, 2026.” It adds: “Starting November 17, 2026, we’ll automatically begin migrating your Gems to skills. You will be able to use your Gems until they migrate.”

So nobody has to do anything to keep their Gems, according to Google: they will be converted automatically, and they keep working until then. Google hasn’t said how long the migration will take. The notice links to a Google support page for more details, but that page didn’t exist when Android Authority checked on Monday.

What skills are

Skills do the same basic job as Gems: they let you give Gemini a set of custom instructions for a particular task. The difference is how you use them. Instead of opening a separate Gem from a side panel, you call a skill by typing a forward slash in the normal prompt box, and you can use several skills in the same conversation. That makes them closer to the reusable skills now common in other AI tools.

The catch for free users

Gems have been available to everyone, including people on Gemini’s free tier. Skills, for now, are only available to Google AI Pro and AI Ultra subscribers, through the Gemini Spark tab, according to both 9to5Google and Android Authority. Google hasn’t said what will happen to free users’ Gems after November 17, or whether skills will come to the free tier before then.

Availability could be a problem in some countries too. Readers commenting on the 9to5Google report asked whether people in regions where Gemini Spark isn’t available will lose Gems without getting skills in their place. Google hasn’t answered that yet.

Until Google publishes its support page, a sensible precaution is to copy the instructions from any Gems you rely on and keep them somewhere safe, so you can recreate them if the migration doesn’t go smoothly.

Why it matters

Gems are one of the main ways people make Gemini work the way they want, and many have built up a collection of them. If skills stay behind a paywall, Google will have turned a free feature into a paid one. We’ll update this story when Google’s support page goes live.
