MailMaestro vs AI Reply Writer: an email assistant or a reply tool for every app?
MailMaestro (formerly Flowrite) vs AI Reply Writer: an AI email assistant for Outlook and Gmail, versus one reply button for email, chat, social and reviews.
MailMaestro, which took over Flowrite's email business, is an AI email assistant for Outlook and Gmail: it drafts emails and replies, summarises threads, and offers templates for teams. AI Reply Writer covers email too, but its reply button works on 23 sites, including WhatsApp Web, LinkedIn, Instagram, Slack and review sites. Choose MailMaestro if your work happens almost entirely in email; choose AI Reply Writer if your replies are spread across many apps.

What MailMaestro is
MailMaestro is an AI assistant that lives inside your email. It drafts new emails from short prompts, writes replies that use the thread as context, rewrites drafts, and summarises long threads. It is aimed at professionals and teams, with shared templates for repeated emails. Flowrite, one of the early AI email tools, passed its email business to MailMaestro's maker, and Flowrite users were directed there.
What AI Reply Writer is
AI Reply Writer drafts replies in Gmail and Outlook on the web too — reading the thread and attachments such as photos and PDFs — but email is only part of what it covers. The same ✦ AI Reply button sits in the reply box of 23 sites.
- Chat: WhatsApp Web, Messenger, Telegram, Slack, Teams, Discord, Google Chat.
- Social: LinkedIn, Instagram, Facebook, X, YouTube, Reddit and more.
- Reviews: Google Business Profile and Trustpilot, reading the stars.
- A Follow-ups list of promises made in your replies, with dates.
The main differences
Email depth vs app breadth
MailMaestro is built only for email, with features such as thread summaries and team templates. AI Reply Writer trades some of that email-specific depth for covering the other places people now reply: chat apps, social media and review sites.
Outlook desktop
If your team works in the Outlook desktop app, check MailMaestro's support for your setup. AI Reply Writer works in Outlook on the web in your browser, not in the desktop app.
Customers outside email
Businesses whose customers write on WhatsApp, Instagram or Google reviews will get more from a tool that works there too.

Which should you choose?
