The best AI email assistant for Gmail depends on one question: do you want to get faster inside email, or do you want the work around email done for you? Clients like Superhuman and Shortwave do the first. Assistants like Fyxer, Inbox Zero and Momo AI do the second, inside the Gmail you already have. Here are nine options with prices read on 11 October 2026, and a plain recommendation for each kind of user.

## 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](/ai-chief-of-staff). 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](/compare/momo-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](/alternatives/fyxer).

## 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](/blog/gemini-in-gmail-what-it-can-do) has the detail.
