Choose the assistant that fits your inbox and account: Gemini is the most direct fit for people who use Gmail and want help with email threads, searches, replies, and drafts inside Gmail. Outlook Copilot offers writing and inbox tools in Outlook, but eligibility depends on the account, license, app, and mailbox. Microsoft also supports Copilot with some connected Gmail, Yahoo, and iCloud accounts in supported Outlook apps; that does not mean every Outlook Copilot feature works with every connected account. Shortwave is another AI email service to investigate, but its homepage description alone is not enough to compare its features or privacy controls.

Can Gemini or Copilot summarize and search email?
Gemini in Gmail
Google describes Gemini as able to summarize a thread and answer more involved questions about email. Its inbox search can help retrieve details from messages, including receipts or confirmation numbers. This is useful when the source is already in Gmail and you want a summary or a detail without manually scanning a long conversation.
Copilot in Outlook
Microsoft documents thread summaries and inbox triage in Outlook. Copilot can also create or manage rules in natural language, and its chat can work with organizational and web information. The supported Outlook experience and mailbox type matter: Microsoft says Outlook Copilot scenarios apply to a user’s primary mailbox and do not apply to certain archive, group, shared, or delegate mailboxes. Mailboxes not hosted on Exchange Online are not supported for these scenarios.

Which assistant helps with drafts and replies?
Gemini: compose, polish, and reply in Gmail
Google describes prompted draft creation, draft polishing, and contextual replies. Gmail can also use a Google Drive file as a reference when composing. These functions make Gemini a natural choice if you want writing assistance without moving your Gmail workflow into another email client.
Copilot: draft and coach in Outlook
Microsoft documents prompted email drafting that can draw on the thread and organizational context, along with coaching on tone, sentiment, and clarity. Treat the result as a starting point: Microsoft advises users to “review, edit, and verify” AI-generated content. Check names, dates, factual claims, and any commitment before sending.

Can Copilot work with Gmail?
Microsoft says eligible subscription or work/school Copilot access can be used with connected Gmail, Yahoo, and iCloud accounts in supported Outlook apps. Connected Experiences must be enabled, and the connected-account sharing feature is unavailable in classic Outlook for Windows.
This is a statement about using Copilot with eligible connected accounts in supported Outlook experiences—not a promise that all Outlook Copilot functions work with Gmail or with every mailbox. Microsoft’s feature guidance includes separate limits for mailbox type and protected messages. Check the specific feature and app you intend to use before relying on it.

What account or plan do you need?
Gmail and Gemini
Google’s Gemini in Gmail page says personal Gmail access is available to users with a Google AI or Ultra plan and that Gemini is included with Google Workspace subscription plans. Google’s Gmail Help availability listing also qualifies access by plan, language, and platform. Availability can differ by account and region, so verify the feature in your own Gmail rather than assuming that every Gmail account includes it.
Outlook and Copilot
Microsoft’s Outlook Copilot FAQ describes access that varies by license and scenario, including a work Copilot license for some functions. Eligibility also depends on the Outlook app and mailbox. Some encrypted or labeled messages are unsupported. If you use a connected third-party account, check both the connected-account requirements and the limitations for the particular feature you want.

Third-party services
Shortwave’s homepage describes it as an AI email automation service. That description does not, by itself, establish which email providers it supports, what its specific AI features do, or what privacy controls apply. Before connecting an account, look for current provider compatibility, feature documentation, and privacy terms for the exact service and plan.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What do the vendors say about privacy and review?
In a Gmail privacy post published April 7, 2026, Google said that it does not train its foundational AI models, including Gemini, on personal emails, and that Gemini in Gmail does not retain user data. These are Google’s statements about its own practices, not independent audit findings; they should not be generalized to every Google AI product.

Microsoft’s guidance emphasizes human review rather than making a comparable privacy claim here: it says to review, edit, and verify generated content. For either service, check the current terms and any organization-specific settings that apply to your account before using AI with sensitive messages.
Which AI email assistant fits your account?
- You use Gmail and want assistance inside Gmail: Start with Gemini if your account and plan have the features you need. Its documented tools cover thread summaries, inbox search, drafting, polishing, and contextual replies.
- You use Outlook and want help across writing and inbox tasks: Check Copilot eligibility for your license, app, and primary mailbox. Its documented Outlook functions include drafting, coaching, summaries, triage, and rules.
- You use Gmail but prefer Outlook: Microsoft documents Copilot for eligible connected Gmail accounts in supported Outlook apps. Confirm that your connected-account setup and the individual Copilot feature both meet their requirements.
- You are considering a third-party service: Evaluate its provider support, feature details, privacy terms, and account permissions before connecting your inbox. Do not infer those details from an “AI email” label alone.
Whichever assistant you choose, use it to prepare or locate information—not to bypass review. Verify consequential details and edit the message so it reflects what you actually intend to say.
