Gemini skills: setup guide and the Gem fallback

Last checked 11 October 2026 against Google's own help pages. See the official guide

Yes, Gemini can use skills on a personal Google account: click Customize, Skills, Upload and choose the skill's .zip. Work and school accounts get skills in the Gemini app from 13 October 2026, rolling out to mid-November. Until then, use a skill's Gem version if it has one, offered up to 1 June 2027.

Three ways to add skills to Gemini

Link Gemini to Trilly once. Then ask Gemini for a skill. Only in the US, with a personal Google account. Trilly hasn't tried linking from Gemini yet.
Copy a skill in, no download. If a skill has a copy-and-paste version, choose Show it to copy on its Add to my AI page. Copy its name, description and instructions into Customize, Skills, Create manually. It won't update by itself.
Download a skill and add it yourself. Step by step

Reads skills on its own: On some plans or versions only.

What you need: A personal Google account, aged 18 or over, with Keep Activity turned on. No paid plan needed. Skills work in the Gemini web app, the Mac app and the mobile app. Google is rolling skills out gradually, so some accounts may not see Skills yet. Work and school (Google Workspace) accounts get skills in the Gemini app from 13 October 2026, rolling out until mid-November.

Step by step

Get the skill from Trilly
On the skill's Trilly page, press Add to my AI, choose Gemini and download the .zip. Trilly makes it for Gemini, with SKILL.md at the top as Google asks, so upload it as it is.
Open Skills in Gemini
Go to gemini.google.com. On the sidebar, click Customize (if you don't see it, click More first). At the top, click Skills.
Upload it
At the top, click Upload, choose the .zip, then click Open.
Check and create
Gemini shows the skill's name, description and instructions. Check them, then click Create at the top.
Use it
In a chat, type / (or @) and choose the skill, or just ask. Gemini also uses active skills by itself when they fit.

Connectors and browser helpers

Checked 12 October 2026. Each skill on Trilly says what it can do beyond the chat under "What you get". You choose: let your AI use your apps and do the clicking, or get a copy-ready version to paste yourself. What connected apps and browser helpers are

Connected apps. Gemini works with Google's own apps (Gmail, Calendar, Drive, Docs, Sheets, Keep and Tasks) and a few others, such as Wix and OpenTable. Open Settings, then Connected apps. On personal accounts it can find and sum up Gmail and Drive, and add to Calendar, Keep and Tasks.

Browser helper. Gemini in Chrome (auto browse) is in the US only, with Google AI Pro (US$19.99 a month) or Ultra, in Chrome on a computer, in English. It asks before it sends or submits anything. Elsewhere, use Claude in Chrome, ChatGPT Work or Comet with a Trilly skill.

Limits Google sets

A skill can be up to 100 MB in total.
Allowed files are text and code (such as .md, .txt, .json, .csv and .html), PDFs and images. Word and Excel files (.docx, .doc, .xlsx) aren't accepted.
Scripts inside a skill can't reach the internet.
You can keep as many skills as you like, but only 100 can be active at once.
Skills don't work with Canvas or Deep Research yet, and you can't share them yet.

A word on privacy

Keep Activity means Google may use your activity to improve its services, including training its models. Keep client names and private details out of chats on a personal account.

Turn off, update or delete a skill

Turn off: on the Skills page, click the skill, then More, then Deactivate. Click Activate to turn it back on.
Update: click More, then Replace skill, and upload the whole new .zip.
Delete: hover over the skill, click More, then Delete. This can't be undone.

Work and school accounts

Google is bringing skills in the Gemini app to all Google Workspace customers, work and school accounts included, from 13 October 2026, finishing around mid-November. Google Workspace has its own skills, built in Workspace Studio. They need Gemini Beta and an admin switch, and they don't sync with Gemini app skills.

Until then, use the Gem version, if the skill's maker made one. Trilly offers Gem versions up to 1 June 2027:

On the skill's Add to my AI page, choose the Gem version.
In Gemini, open Gems in the sidebar and choose New Gem.
Give it the skill's name and paste the Gem version into the instructions.
If the page lists extra files, add them under Knowledge.
Save, then chat with the Gem when you want the skill's help.

Gems on business accounts keep working until no sooner than 1 March 2027, and on education accounts until no sooner than 1 June 2027. A pasted copy is a snapshot. It won't update when the maker improves the skill, and Trilly can't count your use in the skill's public numbers.

Linking Gemini to Trilly

Gemini can add custom MCP apps only on personal accounts in the US, in English. So most people in Australia can't link Gemini to Trilly. Download and upload the skill instead. Your Trilly library shows when a skill you added has a new version.

Gemini CLI is now Antigravity CLI

Google replaced Gemini CLI with Antigravity CLI for Free, Google One, AI Pro and Ultra users on 18 June 2026. To use skills in Google's coding tools, see the Antigravity guide.

Why Gems are becoming skills: AI skills vs prompts vs custom GPTs.
Google's own pages: skills in the Gemini app and Gems turning into skills.

Questions people ask

Do I need Google AI Pro for skills?

No. Google says skills in the Gemini app need a personal Google account, age 18 or over, and Keep Activity turned on. No subscription is needed.

What happens to my Gems?

On personal accounts, Google turns Gems into skills from November 2026. Business accounts follow no sooner than 1 March 2027, and education accounts no sooner than 1 June 2027. Each moved skill keeps its name, instructions and files, and you check it and turn it on.

Can a Gemini skill reach the internet?

No. Google says scripts in a skill can't reach the internet or act on other websites. Trilly also checks every skill for anything that tries to send your information away.

How do I update a skill?

On the Skills page, open the skill, click More, then Replace skill, and upload the whole new .zip from Trilly. Your Trilly library shows when a skill has a new version.

Why don't I see Skills under Customize?

Google is rolling skills out a bit at a time, starting with personal accounts. Check you're signed in to a personal account, are 18 or over, and have Keep Activity on.
