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.

  • Voice matching from your real sent mail, not templates
  • Recipient-aware drafts that adapt to who you are emailing
  • Prompt Lab for version-controlling and A/B testing your persona prompt

  • Training data export and full data portability

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.

Questions & Answers

As answered by people managing BirdReply and ForthWrite.

Which are the primary technologies used for building your product?

ForthWrite's answer:

Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API

What makes your product unique?

BirdReply's answer

BirdReply is unique because it connects three things in one workflow:

  • It understands what your SaaS actually solves.
  • It finds fresh conversations where people are already discussing that problem.
  • It helps you write a useful, natural reply without posting automatically.

Instead of generating generic marketing ideas, BirdReply points you toward real customer pain and shows you where to participate while the conversation is still relevant.

ForthWrite'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.

Why should a person choose your product over its competitors?

BirdReply's answer

People should choose BirdReply if they want customer opportunities they can act on immediatelyโ€”not just keyword alerts or broad social-monitoring data.

BirdReply is built specifically for small SaaS teams:

  • Understands the product and customer problems from the website
  • Finds fresh, relevant conversationsโ€”not just mentions
  • Prioritizes real buyer pain, recommendations, and alternatives
  • Explains why each thread may be a good fit
  • Generates a helpful reply draft while keeping the founder in control
  • Focuses on turning conversations into genuine customer relationships

The difference is the workflow: discover the right conversation, understand the opportunity, and respond helpfully in one place.

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.

How would you describe the primary audience of your product?

BirdReply's answer

BirdReply is built for indie hackers, SaaS founders, and small product teams who need to find their first customers without a large marketing or sales budget.

It is especially useful for founders who want to discover real customer pain, join relevant online conversations, and turn helpful replies into product awareness, signups, and feedback.

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.

What's the story behind your product?

BirdReply's answer

BirdReply started with a simple realization: AI had made building a SaaS dramatically faster, but finding customers was still just as difficult.

I could create a product, launch it, and improve it quicklyโ€”but none of that mattered if the right people never discovered it. The most valuable potential customers were already discussing their problems online, but finding those conversations was slow and unpredictable.

BirdReply was created to help founders discover those fresh conversations, understand the underlying customer pain, and respond with something genuinely useful.

It is built around a simple belief: the best early distribution often starts by helping people who are already looking for a solution.

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.

    I built ForthWrite to fix generic AI email, and I still use it every day

    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.
