Share a Gemini Gem or Canvas

Hand someone a custom assistant you set up — your instructions and reference files baked in — or an interactive doc Gemini built with you, as a link they open and use. A Gem can answer from files already in your team's Drive — the reach you get for staying inside Google.

Reach for it when you're already in Google's world and want a sharable assistant or doc without leaving it. Skip it when you want your agent to do the sharing (this is all manual) or to reach non-Google people with an interactive app — a Claude Artifact is the cross-provider equivalent and opens for anyone.

It allows you to

  • Hand over an assistant, not just an answer. A shared Gem lets others chat with the helper you configured — your instructions plus reference files — as if you'd built them a tool. [confirmed]
  • Ground it in your team's Drive. A Gem can answer from files you keep in Google Drive — the reason to pick this over a non-Google tool. [confirmed]
  • Hand over an interactive doc. A shared Canvas opens as a live link they use, edit, and copy — the same present-to-use pattern as a Claude Artifact. [confirmed]
  • Pick use-only or let them edit, and pull it back. Viewer runs your Gem untouched, Editor can rewrite or delete it, and switching to Private drops it out of their Drive. Details: Who can get in. [confirmed]

Ideal for

  • A Gem grounded in your team's Drive — a "research digester" that reads from your shared folder of reports and hands the whole team the same synthesis, no programming needed. Google's nonprofit blog cites exactly this: Dutch Bamboo's research-digester Gem.
  • A Canvas a Workspace team co-uses — a planning doc or mini-tool you and your colleagues open, edit, and copy from one g.co/gemini/share link, all inside the org's existing Google login.
  • A ready-made helper for non-technical colleagues — a Gem with your tone and rules baked in, shared as Viewer so they run it without changing how it works.

Who can get in

  • Two roles. Viewer uses it; Editor can rewrite, re-share, or delete it — hand Editor out deliberately. [confirmed]
  • No account needed to use a shared Gem. Anyone with the link can use it without signing in to Google. [confirmed] (For a Canvas, the docs don't say. [unclear])
  • Account type bounds reach. A personal account shares all the way to public; a work account is capped by admin Drive policy, which can block external sharing. Full split → the fine print. [confirmed]

Which rungs it can hold. Just you / named people / org-only / anyone with the link / public — all five on a personal account. → Who can see it? [confirmed]

Handing data to the host. Hosted by Google; a paid Workspace account doesn't train on your files by contract, while consumer Gemini trains by default unless you flip one setting. → Can you trust the company? [confirmed]

What you do to set it up

There's no agent path — this is manual in the Gemini web app, because Gemini exposes no sharing API your agent could call. Build the Gem at gemini.google.com, click Share, pick the access, and copy the link (a Canvas uses Share & export atop the Canvas panel).

  • The Share click is the un-delegable step — roughly ~2 min per share once the Gem exists. [estimate]
  • One catch that blocks sharing: a Gem with knowledge files only shares if those files are Drive or device uploads — not a code folder or your Gmail. Swap them first. [confirmed]
  • One-time: a free Google account with Gemini can build and share Gems, ~5 min once. [estimate]

What the other person does

  • Use it: open the link and chat with the Gem (no sign-in needed), or view/edit/copy the Canvas. [confirmed] for the Gem; whether a Canvas needs a Google account to open isn't documented. [unclear]
  • Edit a Gem's setup: needs Editor plus a Google sign-in — a free account, ~3 min once if new. [confirmed]
  • Cost to them: nothing.
    • Shared Canvas links open in the browser, not the Gemini mobile app. [confirmed]

Other ways to share

  • Want your agent to do it, or to reach non-Google people with an interactive app? → a Claude Artifact. Same click-a-link-it-runs as a Canvas, cross-provider, and openable by anyone.
  • Want an ongoing shared AI workspace, not a single assistant? → a shared AI workspace (Claude or ChatGPT Projects) keeps a group's files, instructions, and chats in one place over time.
  • It's really a document people read or mark up? → export the Canvas to a Google Doc — one-tap viewing, no account, comments in the margin.

Good to know

  • Editor can delete your original, not just edit it — for most hand-offs share as Viewer, or tell people to make a copy. [confirmed]
  • Gem sharing is recent (launched 2025-09-18) and rides on Google Drive's share machinery, so your org's Drive rules govern reach. Full dates and caveats → the fine print. [confirmed]
