AI mail drafting, without leaving your inbox

Generate accurate replies, summarise long threads, polish your wording and translate messages — powered by GPT-6 Astra. Start with the Gmail add-on, or step up to an AI assistant that handles the whole inbox for you.

Two ways to put AI in your email

Gmail add-on

AI Mail Assistant for Gmail

A lightweight add-on that lives inside Gmail. Install it and it works on the messages you already have — no migration, no new inbox, nothing to configure.

  • Generate a full reply from a short instruction, in the tone you choose
  • Summarise long threads down to the points that actually matter
  • Improve grammar and wording before you hit send
  • Translate messages in 13 languages, both directions
  • Ask ChatGPT a question without leaving the Gmail window

Klart AI platform

Klarty, your AI executive assistant

For teams that want more than drafting. Klarty reads and writes across the whole inbox, prepares the meetings that come out of it, and tracks what was promised — grounded in your real company sources, with citations.

  • Reads and drafts across your full inbox, not one message at a time
  • Books and prepares meetings, and takes notes on the calls
  • Tracks every open item so follow-ups stop slipping
  • Answers only from sources you connect — with citations, or it says it does not know
  • Works in Gmail, Slack and Microsoft Teams under permissions you set

What AI email drafting actually handles

Replies that sound like you

Give a one-line instruction and get a complete draft back, matched to the tone you pick — brief, formal, friendly — instead of a blank compose window.

Long threads, summarised

Twenty messages of back-and-forth reduced to the decisions, the open questions and who owes what, so you can answer without re-reading everything.

Grammar and wording polish

Catches mistakes and suggests cleaner phrasing before the message goes out — particularly useful when you write in a second language.

Translation in 13 languages

Read an incoming message in your language and reply in theirs, without copying anything into a separate translation tool.

AI email drafting — common questions

The Gmail add-on is free to install and includes a usage allowance, with paid tiers if you need more volume. Klart AI is a separate product with its own free tier and paid plans — see the pricing page for that.

If you want AI drafting inside Gmail for yourself, take the add-on: it installs in a minute and needs no setup. If you want an assistant that works across a team, answers from your internal documents with citations, and handles calendar and follow-ups as well as email, that is Klart AI.

The Gmail add-on runs on OpenAI GPT-6 Astra. Klart AI routes each task to the best model for the job — OpenAI, Claude, Mistral and others — under one set of governance and sourcing rules, so you are not locked to a single vendor.

The Gmail add-on only acts on the message you have open when you ask it to. Klart AI works from the sources you explicitly connect and inherits your existing access rules, so it can never surface something you could not already see yourself.
