Gmail's AI Inbox, powered by Gemini 3, launched in January 2026 and gives you conversational search ('what did my dentist send me last month?'), thread summaries, Help Me Write for drafting full emails, and Suggested Replies — all free. The AI Inbox daily briefing and Gmail Live voice interface are paid features. Google opted everyone in by default, but you can turn any of it off in Gmail settings.
Most people search their Gmail the same way they did ten years ago: type a keyword, scroll through results, hope the right email shows up. In January 2026, Google changed that. The new Gmail AI Inbox — powered by Gemini 3 — lets you ask your inbox questions the way you'd ask a person. You don't have to remember a subject line or a sender's name. You can just describe what you're looking for.
Here is how each feature works and where to find it.
What's free and what costs money
Before getting into the steps, a quick overview. Conversational search, AI Overviews in search results, thread summaries, Help Me Write, and Suggested Replies are all free with any Google account. Two features require a paid Google One AI Premium subscription: the AI Inbox personalized daily briefing and Gmail Live (the voice interface, announced at Google I/O on May 19, 2026). Google turned on all AI features for users by default when the AI Inbox launched on January 8, 2026 — instructions for opting out are at the end of this guide.
Ask your inbox a question instead of searching
Click the search bar at the top of Gmail and type a question in plain English, the way you'd describe it to someone else.
What did my doctor's office send me last month?
Is there an email about my car insurance renewal?
Find emails with attachments from the plumber who gave me a quote
Gmail's AI Overviews show a summary answer at the top of the results, followed by the matching emails underneath. You don't need to remember the sender's exact name or the subject line — the AI reads the content of your messages to find what you're asking about.
Catch up on a long thread with a summary
Open any email thread that has grown beyond a few messages. At the top of the conversation, look for a "Summarize this email" chip or button, or a summary card that may appear automatically with a brief recap.
Tap or click it to get a short summary of the whole exchange: who said what, what was decided, and what (if anything) still needs a response.
This is particularly useful for long family group threads, work emails you were copied on, or any chain that grew while you were away. Instead of reading 20 messages in order, you read one paragraph and then decide whether you need to go deeper.
Draft an email with Help Me Write
Start composing a new email (the pencil icon or Compose button, usually at the bottom left). In the compose window, look for a small icon near the bottom of the text area — it may look like a pen, a star, or a sparkle, depending on your version of Gmail.
Click it and choose "Help me write." Then type a short note about what you want the email to say:
Politely reply that I can't make the meeting on Thursday and suggest Friday afternoon instead
Write to the tradesman who gave me a quote last week and ask if the price is still valid
Gmail will draft a full email based on your note. Read it through, fill in any details the AI left as placeholders, and edit anything that doesn't sound like you. You can also ask it to adjust the tone — more formal, friendlier, or shorter — before you send.
Use Suggested Replies for quick responses
When you open an email that ends with a question or a request, Gmail often shows two or three short reply options below the message: something like "Sounds good, I'll be there" or "Thanks, I'll take a look."
Tap one to open it as a draft you can edit before sending, or ignore them if you want to write your own reply. The 2026 AI Inbox update made these suggestions more context-aware — they now draw on the full thread, not just the last message.
Try the AI Inbox daily briefing (paid feature)
If you have a Google One AI Premium subscription, look for the AI Inbox section near the top of your Gmail. It shows a personalized summary of what needs your attention today: packages arriving, upcoming appointments confirmed by email, bills due, and priority messages from people you hear from regularly.
The briefing puts emails from your frequent contacts first. You can dismiss it once you have read it, or tap individual items to open the underlying email directly.
Turn AI features off if you'd rather not use them
Google enabled AI features for all users by default, but turning them off takes less than a minute.
On Gmail on the web: click the gear icon (top right) > See all settings > General tab > scroll to Smart features and personalization > toggle it off.
On the Gmail app (Android or iOS): tap your profile picture > Manage your Google Account > Data & privacy > scroll to More options > Other Google activity > Gmail smart features and personalization > turn it off.
Disabling this turns off thread summaries, Help Me Write, AI Overviews in search, and Suggested Replies. Your email continues to work exactly as before — you just see no AI assistance.
What to watch out for
Summaries can miss nuance. A thread summary gives you the shape of a conversation, but tone and context can get lost. A sarcastic "fine, if that's what you want" might be summarized as agreement. For anything important — medical, legal, financial — read the actual emails before acting on a summary.
Help Me Write doesn't know your specifics. If you ask it to reply to a tradesman about a quote, it won't know the quoted amount, the job details, or the contractor's name unless you put them in your prompt. Read the draft before sending and fill in anything it left as a generic placeholder.
Your emails are being processed by Google. The AI reads your email content on Google's servers to make these features work. Google says it does not use personal Gmail content for advertising, but if you use Gmail for sensitive work, check your employer's data policies before using AI drafting features.
Gmail Live is still rolling out. The voice interface was announced at I/O in May 2026 for Google AI Ultra subscribers. If you cannot find it, it may not have reached your region or account type yet.
Proofread is a paid feature. The Proofread tool, which reviews your draft for grammar and tone, requires a Google One AI Premium subscription — it is not part of the free features.
