GemAI writes and checks email for you without leaving the compose window. Give it a short prompt and it drafts the message, or hand it what you already wrote and it proofreads it.
Where the GemAI buttons are
Open Compose, or a reply, and look at the bottom-left of the compose toolbar:
- The pen with "AI" opens GemAI Writer in generate mode.
- The lines with a checkmark opens it in proofread mode.
Both appear only while GemAI is switched on, under Settings | Global Settings | Advanced Features | Enable GemAI.
Draft a new email
- Tap the Writer (pen) icon.
- Type a few words describing what you want to say — a whole sentence is not needed.
- Tap the arrow and wait for the draft to type itself out.
- Tap Use to drop it into your message, or Regenerate (↻) for a different version.
GemAI fills in the Subject as well as the body. If the draft addresses someone by name, BlueMail substitutes the real name as it goes in, so a [name] or [recipient] placeholder becomes your recipient automatically. Add the recipient before tapping Use and there is nothing left to edit; write to nobody in particular and the placeholder stays put for you to fill in yourself.
Proofread what you wrote
- Write your message as usual.
- Tap the Proofread icon — the one with the checkmark.
- Read the corrected version and tap Use to replace your text.
Proofreading is non-destructive: you can retry or close the sheet without changing anything you wrote.
Change the length, tone or language
Tap the sliders icon inside the GemAI Writer sheet for:
| Option | Choices |
|---|---|
| Length | Default, Shorter, Longer |
| Tone | Default, Formal, Conversational, Respectful, Informal, Motivating, Exciting, Cautionary, Friendly, Serious, Optimistic |
| Emoji | None, One, A Few |
| Language | The language the draft is written in — also on the flag in the sheet header |
Replying with the thread as context
When you generate a draft inside a reply, a switch labeled Refer to sender's email lets GemAI read the message you are answering first, so the reply matches what was already said. Switch it off — the label then reads Refer to sender's email (not included) — if you want the draft written from your prompt alone.
Summarize an email you received
Open the email and tap the GemAI icon in the mail view for a short summary of the message, so you can see what it says without reading all of it.
If the buttons aren't there
- Check Enable GemAI under Settings | Global Settings | Advanced Features — it may be switched off.
- Some managed or company accounts have GemAI disabled by an administrator.
- "You've Hit Your Daily Limit" means you have used the daily allowance that applies across all GemAI actions. It resets the next day, or upgrade to remove the limit.
