MailHero by AISaver

An AI email context assistant for Gmail: analyze the thread you open, draft and improve replies, and save selected knowledge to Notion.

MailHero by AISaver is a Gmail Add-on. It reads only the Gmail thread you explicitly open—never your inbox in the background—and acts only when you choose an action.

Acme SupportRe: Failed data import

10:42

Hi, the CSV import failed again after we changed the date format. We need this resolved before Friday’s launch.

Could you confirm whether the new parser supports DD/MM/YYYY and who owns the fix?

MAILHERO / CASE BRIEF

Import blocks Friday launch

Fact: Date format changed to DD/MM/YYYY
Risk: Launch deadline is Friday
Next: Confirm parser support and owner

Fluent is not the same as correct.✦Reply with context, not guesses.✦Your email history should compound.✦

One deliberate loop

Today’s email becomes tomorrow’s context.

MailHero stays inside Gmail, does the organizing work, and keeps you in control at every boundary.

01
Analyze—or reply directly
Extract the request, facts, decisions, risks, and next actions from the thread you explicitly opened, or go straight to an AI reply for a simple response.
READ
02
Save what matters
Review the Case Brief, or save a thread directly, to your chosen Notion database. MailHero can create a database in an authorized page and add its missing fields.
REMEMBER
03
Recall on demand
When the next email arrives, select the specific past records you want the AI to use—nothing hidden, nothing automatic.
RECALL
04
Reply with control
Draft from the current thread and selected history, then edit, refine, or translate the response before creating a Gmail draft. You decide whether to send.
REPLY

Not another email writer

Every answer carries its receipts.

MailHero exposes the facts and saved records behind a draft. You can remove context before generation and edit every result before it leaves Gmail.

SUGGESTED REPLY

Hi — yes, the parser supports DD/MM/YYYY. I’m confirming the fix owner now and will send you an update today, well ahead of Friday’s launch.

Privacy is a product surface

Small permissions.
Visible data flow.

Open means readable

MailHero reads the Gmail thread you explicitly open. It does not scan or search your inbox in the background.

Click means saved

Nothing enters Notion until you click Save. You choose whether to include the original email content in that save.

You pick the context

Past records are displayed first. You choose which ones the model may use for a reply.

You press Send

MailHero creates a Gmail draft. It never sends email automatically.

Flexible by design

Use MailHero AI—or bring your own compatible provider.

Choose MailHero’s managed AI service, or connect an OpenAI-compatible provider with your own credentials. Your Notion workspace remains your chosen destination for saved knowledge.

Each action makes its data flow explicit: the current thread, the optional history you select, and the provider you choose.
