How Replai Works - Setup, AI Agents and Reply Automation

You paste a few emails. We learn your style. Agents draft replies in your own words. Here is exactly how it works, step by step.

Quick summary

What does setup actually involve?

Create a free account, no card needed, paste three to five emails you have already written, and Replai handles the rest. It reads your examples, scores your Formality, Warmth, and Directness, and builds your private reply identity. No rules to write, no settings to tune, no software to install.

Once your identity is built, AI agents go to work. Paste in an email you have received and they draft a reply in your exact voice. You review, tweak if you like, and send. Every reply after that gets a little faster and a little sharper.

Every step explained

Exactly what happens at each stage, how long it takes, and what you do.

Step 1
30 seconds

Create a free account

Just your name and email. No credit card. No phone number. No company details. Your account is live in seconds.

A private reply identity number is generated for you automatically.
Your password is hashed and never stored in plain text.
No inbox connection is required at this stage or any stage.
Step 2
2 minutes

Paste three real replies you have written

Open your Gmail or Outlook sent folder, grab three to five emails that sound like you at your best, and paste them in. Short is fine. Formatting does not matter.

Three examples is enough to start. Ten gives a strong match.
Strip out anything sensitive before you paste, if you prefer.
Examples stay private, visible only to you, deletable any time.
What to look for in sent emails: a greeting that comes naturally, your usual sign-off, the way you handle a follow-up. More variety, better analysis.
For a sharper, more accurate match: Connect Gmail or Outlook and let Replai read up to 100 emails from your Sent folder. It learns your voice far better than pasting examples by hand. We never read, store, or share emails you have not explicitly asked us to access, and we never delete anything.
Step 3
Automatic

Replai builds your reply identity

It happens the moment you save an example. Replai reads your writing and produces three style scores. You configure nothing.

Formality
72 / 100
Warmth
88 / 100
Directness
65 / 100

Example scores from a real Replai identity.

It also records your typical greetings and sign-offs.
Scores update every time you add or remove an example.
Step 4
Ongoing

AI agents draft replies in your voice

Paste the email you received into the reply generator. Agents read it, match it to your identity, and write a reply that sounds like you wrote it. You review, tweak if you want, and send.

Each draft is shaped by your Formality, Warmth, and Directness scores.
Nothing is sent automatically. You always review first.
The more you use Replai, the closer it gets to your voice.

Replai vs the other ways to handle email

Most options sound robotic, take hours to set up, or demand full inbox access. Here is an honest comparison.

Setup and how it works - Common questions

No. Replai is a web tool. Open it in your browser, create a free account, and start pasting examples. Nothing to download, no browser extension, no app to set up.
No. Replai needs no inbox connection at any point. You paste your own example emails by hand. That is by design: it means we never read your inbox, which is a core privacy commitment.
Three is the minimum for a style score. Five to eight gives a good match. Ten is the max and produces the most accurate identity. Add, edit, or delete examples any time from your account.
Save your first example and your identity scores are calculated on the spot. From there, the email reply generator is yours to use. Sign-up to first draft takes most people under three minutes.
Replai agents shape the draft from your Formality, Warmth, and Directness scores, your usual greeting, and your usual sign-off. They also read the content and tone of the email you paste in. The result matches how you would genuinely respond.
They get closer the more examples you save. Three gives a rough match. Ten gives a much stronger one. Most people say replies sound noticeably like them after five examples, and that editing drops sharply over time.
