You can polish and correct email in Gmail today. Write the reply however it comes out, tap polish, and FlickReply fixes the spelling, grammar and punctuation and returns 3 to 4 rewritten versions to choose from — that works in every Android app, Gmail included. What does not work in Gmail yet is the AI reply assistant, which reads a conversation and drafts a reply from it; that currently works in WhatsApp and Instagram and Gmail support is in development.
Reply drafting is not available here yet. Polish and correct works in Gmail today, like every other app. The AI reply assistant — which reads a conversation and drafts a reply from it — works in WhatsApp and Instagram today, and Gmail support is in development.
Why Gmail in particular
Email on a phone is where people most often give up and decide to "do it properly at a laptop later" — and later usually means three days. Most of that friction is the blank compose field and the worry that a thumb-typed reply will read as curt. It is a good fit for an AI keyboard, which is why it is next on the list.
Three things reply drafting in Gmail is being built for
These describe reply drafting, which is not in Gmail yet — it works in WhatsApp and Instagram today. Polishing and correcting a message you have written already works here.
Turning a two-line thumb reply into something sendable
The intended workflow: write what you actually mean in the shortest possible form, then refine it into a professional tone — far faster than composing a formal email on a phone keyboard. This is how it already works in WhatsApp and Instagram, and how it is designed to work in Gmail.
Replying to a long thread from your phone
Tap the AI key in the compose field and have it draft from what is there, then edit. The first draft is the expensive part on mobile; editing one is not.
Keeping the tone right for the recipient
The same information going to a client and to a colleague are different emails. Switching a written draft between professional and friendly is the feature that would carry the most weight here.
What it actually returns
Real messages, typed the way people actually type them, and the versions that come back.
Replying to a colleague you have left waiting
What you typed
hey sorry i didnt get bak to u yesterday was swamped, can we push the call to thurs? also i still need those numbers from ur team before we can finalise anythign
What comes back
Apologies for the slow reply yesterday — it was a busy one. Could we move the call to Thursday? I also still need those figures from your team before we can finalise anything.
Sorry for not getting back to you yesterday, things were hectic. Can we push the call to Thursday? I'll also need those numbers from your team before we can wrap this up.
Sorry for the delay. Can we move the call to Thursday? Still waiting on your team for the numbers before we finalise.
Four spelling errors, two missing apostrophes and a run-on sentence, fixed in the same pass as the rewrite. The third version is what the short tone produces.
Declining something without sounding blunt
What you typed
cant do friday, got too much on. maybe next week idk
What comes back
Friday is not going to work for me — I have too much on. Could we look at some time next week instead?
I can't manage Friday, unfortunately. Would next week be easier?
Can't do Friday. Next week work?
The original is not rude, it just reads as though you could not be bothered. This is the most common reason people reach for polish.
When it will not help
Worth knowing before you install rather than after.
It cannot know what you meant
If the original message is ambiguous, the rewrites will be confidently ambiguous in 3 to 4 different ways. Polish improves how a message reads, not whether the underlying thought was clear.
It will flatten a deliberate voice
If you write in a distinctive way on purpose — clipped, blunt, very informal — the rewrites will smooth that out. Some people polish everything; others only use it for work messages for exactly this reason.
It is not an as-you-type corrector
Nothing changes until you tap. If you want mistakes fixed silently while you write, that is autocorrect, and FlickReply does not replace it.

AI reply assistant that drafts an email from the thread you are replying to
Re-toning a generated draft between professional, friendly and short
FlickReply is an Android input method, so the system hands it every text field on the device — the keyboard itself, the whole tools panel, and polishing a message you have written all work in Gmail, your browser, your notes app and anything you install next month. Only reply drafting is per-app, because it reads the conversation on screen, and that works in WhatsApp and Instagram today.
Setting it up takes about two minutes
Install FlickReply from Google Play. It is free, and the AI allowance on the free tier is 10 requests a day.
Enable it in Android keyboard settings. Android walks you through enabling a new input method and then selecting it — the prompt appears on first launch.
Tap polish on anything you write. In Gmail that already corrects the spelling and grammar and gives you several rewritten versions, plus the full keyboard and tools panel. For a reply drafted from the conversation, open WhatsApp and Instagram — Gmail will work the same way once support ships, with nothing to reinstall.
FAQ
Gmail and FlickReply: common questions
Partly, today. FlickReply can correct and rewrite an email you have written in Gmail right now: tap polish and it fixes the spelling, grammar and punctuation and gives you 3 to 4 rewritten versions to pick from. That works in every Android app. What it cannot do yet is read an email thread and draft a reply to it from scratch — reply drafting works in WhatsApp and Instagram and Gmail support is in development with no confirmed date.
There is no announced date. Gmail is one of the next apps planned for AI support, along with LinkedIn. We would rather say that plainly than publish a date and miss it — if you want to know when it lands, the contact page is the fastest way to ask to be told.
You can use it as your keyboard in Gmail today, which gets you clipboard history, emoji, the text editing and share tools, keyboard resize, one-handed mode and the floating keyboard. For the AI drafting and rewriting, you would need to be in WhatsApp and Instagram. Nothing stops you from drafting in one of those and pasting into Gmail, but that is exactly the copy-paste round trip FlickReply exists to remove, so it is a workaround rather than a recommendation.
No, and it will not when Gmail support ships. FlickReply is an Android keyboard: it has no connection to your Google account, no OAuth permission and no access to your mailbox. It works with the text in the field you are typing in, nothing more.
Correcting and rewriting a message works in Gmail right now, free. Reply drafting works in WhatsApp and Instagram today and Gmail will follow, with nothing to reinstall.
