Smart Reply in Gmail
ForthWrite is an AI email writing assistant for Gmail and Outlook that learns your writing style from your real sent mail. The more you use it, the more it sounds like you. Get smart drafts in seconds, auto-draft replies before you open your inbox, and maintain your personal voice at scale. Free to start, no credit card required. Works inside Gmail and Outlook on the web.
How it works
ForthWrite captures your tone, sentence rhythm, and sign-offs from your actual sent emails, then uses that profile to generate drafts that match how you write, not a generic AI voice. Every draft you edit or send improves the model over time.
Key features
Who uses it
Professionals who send high volumes of relationship-critical email: lawyers, financial advisors, recruiters, account executives, founders, and anyone who wants their inbox handled without sounding like a chatbot wrote it.
Pricing
Free tier includes 10 drafts per week with no credit card required. Paid plans start at $12/month and include unlimited drafts, custom persona prompts, and auto-draft.
ForthWrite
Smart Reply ProForthWrite's answer
ForthWrite learns your writing style from your actual sent mail, not a generic prompt. Every draft sounds like you wrote it because it was trained on how you actually write. It also auto-drafts replies before you open your inbox, so your email is partially handled before your day starts.
Smart Reply Pro's answer:
Smart Reply Pro is the only AI built for one specific job: the reply. Instead of trying to do everything like general-purpose chatbots, it focuses on reading the tone, pressure, and intent of any incoming message and drafting five calibrated reply variants in your own voice โ in under a second. It learns your "Tone DNA" from how you write, never logs into your accounts, never auto-sends anything, and never reads your inbox in the background. You stay fully in control: it proposes, you decide.
ForthWrite's answer
Most AI email tools give you a blank box and a "write for me" button. ForthWrite builds a voice profile from your sent history and gets more accurate with every draft you edit or send. Unlike ChatGPT or Gemini, it works natively inside Gmail and Outlook with no copy-paste. Unlike Lavender, it writes the draft, not just scores it.
Smart Reply Pro's answer:
Three reasons. First, it sounds like you, not like AI โ Style learning mirrors your cadence, vocabulary, and restraint, so the longer you use it the more it matches your voice. Second, it's privacy-first by design: no inbox access, no OAuth, no IMAP/SMTP, no auto-send, no training on your messages, no selling data. The extension only sees text you actively select. Third, it's fast and tactical โ sub-second drafts with five voices (Neutral, Direct, Polite, Friendly, Confident) plus Pro tactical modes, a Command Palette, Tone Morph dial, and Hover Oracle that reveals the sender's true pressure and hidden ask. And the pricing respects you: free tier with 5 replies a day, Pro at โฌ6/month, cancel anytime.
ForthWrite's answer
Professionals who send high volumes of relationship-critical email and cannot afford to sound generic: lawyers, financial advisors, recruiters, account executives, consultants, and founders managing their own inbox.
Smart Reply Pro's answer:
People who write for a living and want their messages back without losing their own voice. Specifically: founders, freelancers, recruiters, customer support teams, short-term rental hosts, sales professionals, and anyone who handles a high volume of email, LinkedIn, Slack, WhatsApp, or DMs and cares about tone, boundaries, and privacy. It's for people who've tried ChatGPT for replies and felt it sounded like a stranger pretending to be them.
ForthWrite's answer
Built out of frustration with AI writing tools that produce text that sounds nothing like the person sending it, and as a way to handle large amounts of daily email. The core insight was that your sent mail is the best training data you already have, and no tool was using it.
Smart Reply Pro's answer:
Smart Reply Pro was built by Darko, a solo founder based in Serbia, after every "AI reply" tool he tried sounded like a stranger pretending to be him. He wanted a reply assistant that learns your actual voice, respects your privacy as a foundation rather than a marketing line, and never automates anything on your behalf. So he built it himself โ one person reads every bug report, one person reads every refund request, and the privacy promises on the site are the reason the product exists in the first place.

Smart Reply Pro's answer:
Based on what's publicly visible: a Next.js web app (the site uses Next.js image optimization) hosted on Vercel, a Chrome extension built on Manifest V3 that works across all sites, HMAC-SHA256 webhook verification for backend integrity, environment-isolated secrets in Vercel, least-privilege database roles, and a PCI-DSS-compliant Merchant of Record handling payments so card data never touches the app directly. GDPR-compliant with Article 33 breach response within 72 hours.
Smart Reply Pro's answer:
The website doesn't list named enterprise customers (this is an indie product, not an enterprise SaaS), so I'd suggest answering honestly with the customer segments the product serves. Something like:
Short-term rental hosts managing guest inboxes Founders handling investor and customer messages Recruiters running high-volume candidate conversations Customer support teams across SaaS and e-commerce Freelancers managing client communication Sales professionals working deal threads on email and LinkedIn
I built ForthWrite because I kept sending emails that sounded like they came from the same generic AI as everyone else. After launching it, I still use it for my own inbox every day, which is about the most honest endorsement I can give.
The Chrome extension lives inside Gmail and Outlook on the web. Open a thread, hit Alt+Shift+D, and a draft comes back in your voice, not a template. The free tier is real: 10 drafts per week, no API key, no credit card. Voice matching is included on free, because that is the point.
What keeps it useful compared to Gemini or a chat tab: it learns from what you actually send. Every edit you make before hitting send becomes a signal. Over time the drafts drift closer to how you really write, and the dashboard shows the improvement curve so you can see it happening.
The web compose surface lets you draft from forthwrite.ai without installing anything, useful for people who want to try before committing to the extension.
Standard adds recipient-aware and intent-aware drafting plus AI coaching. Pro adds auto-draft (replies waiting when you open Gmail), batch replies, and Prompt Lab for version-controlling your prompts. Teams adds a shared persona and seat-level analytics.
ForthWrite is not for everyone. If you just need quick replies and tone does not matter, Gemini is free and already in your inbox. ForthWrite is for people where tone does matter: client communication, relationship-driven threads, external correspondence where sounding off costs something real.
Disclosure: I am the founder and use it daily. Happy to answer questions in the comments.
