What is the best AI email assistant for Gmail?
For most Gmail users who want follow-ups, scheduling and drafts handled without leaving Gmail, Momo AI is the best fit, and it is free during early access. For speed inside email, Superhuman. For sorting and drafting with Outlook support, Fyxer. For a cheap cleanup tool, Inbox Zero. For on-demand help with the email you have open, Gemini in Gmail if you already pay for it.
We make Momo AI, so read our placement of it with that in mind. Prices are from each vendor's own pricing page on 11 October 2026 and change often.
Decide the shape first
Nine tools, four shapes. Pick the shape and the list gets short.
- Email clients replace Gmail's interface: Superhuman, Shortwave. You still write every email, faster.
- Inbox assistants work on your existing Gmail: Fyxer, Inbox Zero, alfred_, Momo AI. They sort, draft and, in some cases, track and schedule.
- Built-in: Gemini in Gmail. Helps with the open email when you ask.
- General agents: Lindy, Instinct. Email is one of many things they do; more reach, more trust required.
The nine, side by side
Prices are the vendor's own, read on 11 October 2026. "Who sends" is the question most listicles skip and the one that matters most.

Best for follow-ups and scheduling without leaving Gmail: Momo AI
Momo AI is an AI chief of staff for Gmail and Google Calendar. It sorts the week, drafts replies in your voice to Gmail Drafts, flags every thread waiting on a reply with the nudge written, books meetings by emailing free slots, tracks promises in both directions and sends a morning brief. Every email waits for your tap.
Weaknesses: Gmail only, no Outlook; no keyboard-first client; still in early access and Google verification is in progress, so you will see an "unverified app" screen at sign-in. Free now, ₹499 per month planned.
Best for speed inside email: Superhuman
If you process hundreds of emails a day and want each one faster, Superhuman's client is the benchmark: shortcuts, split inbox, snippets, read statuses, Outlook support. AI drafting (Auto Drafts) is on the Business plan. From $25 per user per month annual. You still do the work; see Momo AI vs Superhuman.
Best for sorting and drafting across Gmail and Outlook: Fyxer
Fyxer categorises your inbox and drafts replies in your tone, and it supports Outlook, which Momo AI does not. It has a free tier and Pro at $37 per month annual. It does not track follow-ups or schedule over email. See the Fyxer alternative page.
Best cheap cleanup: Inbox Zero
Inbox Zero is open source with a hosted Starter plan at $18 per month annual. Bulk unsubscribe, cold-email blocking, reply tracking and AI reply drafts. A good pick if your problem is volume rather than follow-through.
Best if you already pay Google: Gemini in Gmail
Gemini summarises, drafts from a prompt and suggests times inside the open email. It is included with Workspace Business Starter (₹270 per user per month annual) and Google AI Pro (₹1,950 per month). It does nothing in the background. What Gemini in Gmail can and can't do has the detail.
How to choose an AI email assistant for Gmail
Five questions, in order.
- 1Does it keep you in Gmail, or replace it? Replacing is a bigger change than it sounds.
- 2Who presses Send? Look for a tool that drafts and waits. Autopilot is where the horror stories come from.
- 3Does it work while Gmail is closed? Follow-up tracking and a morning brief need a background assistant.
- 4Which Gmail permissions does it ask for, and is the app verified by Google? Is it safe to give AI access to Gmail explains the scopes.
- 5What does it cost in your currency? Most are priced in dollars; Momo AI is priced in rupees.
