Let an AI search your Gmail
When you reach the end of this page, you will be able to ask Claude or ChatGPT to find and explain emails in the Gmail account you choose. You will also know how to check its answer, keep sending under your control, and disconnect Gmail later if you want to.
Gmail becomes one of the AI’s tools
A connector or app is a controlled connection between an AI and another service. Here, that service is Gmail. It lets the AI find and read email when you ask a question that needs it. It does not make the AI automatically read your inbox all day.
Connect only an account whose email you are comfortable discussing with Claude. A work or school Google account may need approval from its administrator before it can connect.
What you need
- A computer, tablet, or phone with a browser and either a Claude or ChatGPT account.
- The Google account you want to connect. You sign in on Google’s own page, never by typing your Google password into Claude.
- One email you already know is in your inbox. It gives you a simple way to check whether the connection worked.
Claude or ChatGPT: use the one you already have
Both routes connect only the Google account you choose. The screens will look different, but the safe habit is the same: start by asking the AI to read, check the original email, and approve nothing you do not mean to happen.
Route A: ClaudeOpen Claude’s Gmail instructions
Open Claude and sign in
Go to claude.ai. Start a new chat.
WhyYour connection belongs to your Claude account.
Find the Gmail connector
Use the + beside the message box, then look for Connectors and Gmail. If Gmail is not already available there, ask Claude a Gmail question; it can prompt you to connect Google when access is needed.
WhyConnectors are the part of Claude that can reach services outside the chat.
Choose Gmail and connect it
Follow Claude’s connection prompt. It will send you to Google to choose the Google account you want to use.
WhyGoogle, not Claude, handles the sign-in.
Check the address bar before you sign in
Only enter your password on a Google page whose address starts with accounts.google.com. Choose the account you mean to connect, especially if your browser has more than one Google account signed in.
WhyThis is the moment you choose which inbox Claude can use.
Read the permission screen, then decide
Google may list permission to send email as well as read it. That is because Claude can draft, send, reply to, and forward mail. By default, Claude asks for approval before sending, replying, or forwarding.
WhyRead access helps answer questions; sending is a separate action you should review before approving.
Ask one read-only test question
Use an email you can recognize. Replace the words in square brackets before sending:
Find my most recent email from [person or organization]. Tell me its subject and date, and do not change anything in my Gmail.WhyYou already know roughly what you expect to find, so you can tell whether Claude used the right message.
Check the source before you rely on the answer
Claude normally shows citations or links for the emails it used. Open the message in Gmail and compare it with the answer. For important decisions, treat Claude’s answer as a helpful summary and the original email as the record.
WhyA good habit here prevents a small misunderstanding from becoming a sent email, missed deadline, or wrong decision.
Route B: ChatGPTOpen ChatGPT’s Gmail instructions
Open ChatGPT and sign in
Go to chatgpt.com. Start a new text chat.
WhyYour connection belongs to your ChatGPT account.
Open Settings, then Plugins
Open ChatGPT’s settings and choose Plugins. Find Gmail, or the plugin or app that includes it. If you see Install plugin, choose it and continue with the setup flow.
WhyThat is where ChatGPT keeps the external apps it can use in a chat.
Connect the Google account you mean to use
Choose Connect when ChatGPT asks, then complete Google’s sign-in screen. Only enter your password on a page whose address starts with accounts.google.com. If you have more than one Google account, stop and choose the inbox you actually want ChatGPT to use.
WhyThe connected account controls what ChatGPT can see; it does not get access to your other Gmail accounts.
Review Google’s requested permissions
Read the Google permission screen before you approve it. If ChatGPT says all selected permissions are required, use its option to select fewer Google apps if you only want Gmail, then approve every permission needed for the apps you selected.
WhyAccount permissions, ChatGPT settings, and any work or school administrator rules can all affect what becomes available.
Use Gmail in a chat
In a supported chat, type @Gmail before your question, or use the + menu to select Gmail when it is available. Some ChatGPT screens put this choice under More.
WhyThat tells ChatGPT which connected app you want it to use.
Run the same read-only test
Replace the words in square brackets, then send:
@Gmail Find my most recent email from [person or organization]. Tell me its subject and date, and do not change anything in my Gmail.WhyStart with something you recognize so you can check it against Gmail.
Check the original email
Open the message ChatGPT used, if it provides a reference, and compare the original with the answer. Ask a narrower question if anything is unclear.
WhyThe original email remains the record, especially for decisions, dates, money, or promises.
Start by reading, not changing
These are safe first jobs because they ask Claude to find and explain information. Copy one, change the words in square brackets, and send it.
Ask for the original beside the summary. That is how you stay in the saddle.
Three rules worth keeping
- Say what must not happen. Add “do not send, reply, forward, delete, archive, or label anything” when you only want information.
- Check before approving a write. Claude asks for approval by default before it sends, replies to, or forwards an email. Read what will be sent and who will receive it.
- Use the smallest question first. Ask about one person, topic, or thread before asking Claude to sort a whole inbox.
Turn Gmail off or disconnect it
For one Claude conversation, turn the Gmail connector off from the connector controls near the chat box. To disconnect Claude completely, go to Customize, then Connectors, open the Google connection, and choose Disconnect.
For ChatGPT, open Settings, then Plugins, choose the relevant Gmail app or plugin, open its account options, and choose Disconnect. Disconnecting stops future access; it does not automatically delete existing chats, saved memories, or data already in a conversation.
You can also review connected apps on your Google Account’s linked apps page. Find Claude or ChatGPT/OpenAI there and choose Remove access if you no longer want it to reach that Google account.
Quick fixes
- I cannot find Gmail in Claude or ChatGPT
- In Claude, ask a Gmail question in a new chat and look for its connection prompt. In ChatGPT, check Settings > Plugins. Availability can vary by plan, region, account, interface, and workspace settings. A work or school administrator may need to enable or approve it.
- Google says access is blocked
- That commonly means a work or school Google Workspace administrator has not allowed Claude. Ask the person who manages that account; do not try to work around the block.
- Claude gives an answer but I cannot see the source
- Ask it to link or cite the email it used, then open that email in Gmail. If it cannot show the source, narrow the question and try again.
- Claude asks to reconnect
- Disconnect the Google connection in Claude’s connector settings, then reconnect it and make sure you choose the intended Google account.
A useful boundary
- Claude can search and read Gmail, work with email threads, and help draft messages.
- Claude can see attachment metadata, but Gmail attachment content is not directly available through this connector.
- Claude only uses Gmail when you ask a question or request an action that needs it.
- Connector results can remain with the chat. Do not paste sensitive email text into a chat unless you are comfortable keeping that conversation.
This guide was checked on October 6, 2026 against official documentation: Anthropic’s Use Google Workspace connectors and Gmail connector; OpenAI’s Connecting and managing app accounts in ChatGPT, Connected apps in ChatGPT, and Google app data controls FAQ. The screens and available actions can change, so use the labels you see on your own account.
You can do this one question at a time.
