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

  • Auto-draft: replies waiting in Gmail before you open your inbox
  • 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
  • BYOK support: bring your own API key for Claude, OpenAI, Grok, Mistral, and more
  • Works in Gmail and Outlook on the web, plus a standalone browser widget
  • 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.

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.

Lemmy features and specs

  • Decentralization
    Lemmy is built on the ActivityPub protocol, making it part of the larger Fediverse, which promotes distributed and federated networks, reducing reliance on a single central authority.
  • Privacy
    Being open-source, users can audit the code for security vulnerabilities. Furthermore, federated networks tend to have better privacy controls compared to centralized social media platforms.
  • Open-source
    Lemmy's code is publicly available, allowing anyone to contribute to its development or create their own instances, fostering a community-driven approach.
  • Customization
    Instance administrators can tailor the appearance, rules, and functionalities of their Lemmy instances, offering a more tailored user experience.
  • Community Control
    Communities on Lemmy have more control over their content and moderation policies, which can result in higher quality discussions and interactions.
  • Reduced Censorship
    Because Lemmy is federated, there's less chance of blanket censorship as different instances can have varying rules and policies.

Possible disadvantages of Lemmy

  • Smaller User Base
    Compared to mainstream social media platforms like Reddit or Facebook, Lemmy has a smaller user base, which can limit the variety and volume of content.
  • Learning Curve
    New users might find it challenging to understand how decentralized networks and federated instances operate, which can be a barrier to entry.
  • Instance Fragmentation
    Content and user communities are spread across multiple instances, which can lead to fragmented discussions and a lack of unified content discovery.
  • Variable Quality
    Since any instance can have its own moderation rules, the quality and tone of discussions can vary greatly between instances, potentially leading to inconsistent user experiences.
  • Technical Expertise Required
    Running and maintaining a Lemmy instance requires technical knowledge, which might not be accessible to general users without background in system administration.
  • Limited Features
    As a relatively new and developing platform, Lemmy might lack some features and functionalities that users are accustomed to on larger, more established platforms.

Questions & Answers

As answered by people managing Lemmy 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?

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?

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?

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?

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.

    ๐Ÿ Competitors: Jace.ai, Fyxer, Mailmeteor
    ๐Ÿ‘ Pros:    Drafts land inside gmail and outlook; no copy-pasting from a chat window|Voice matching is on the free tier, not paywalled behind paid plans|No api key, no credit card to start; free tier runs on a server-side proxy|Learns from every edit you make before sending; drafts improve over time|Full keyboard flow: alt+shift+d to draft in any thread, no mouse required|Byok on paid plans, 9 providers supported, keys encrypted at rest|Web compose at forthwrite.ai works without installing the extension at all
    ๐Ÿ‘Ž Cons:    10 free drafts/week is enough to evaluate, not enough for a heavy inbox|Auto-draft, batch replies, and prompt lab all require the pro tier|Early-stage product; fewer third-party integrations than mature inbox tools|No mobile app: the extension and add-in are desktop-only (chrome on web, or the outlook desktop add-in)

  • Lemmy Scraper: export posts and comments from any Fediverse community

  • Moderation on Lemmy is a fucking joke
    A few weeks a go I posted a meme with the caption "My wife out-drinking everyone at the table-- Our unborn son:" [picture of Tom the cat in the womb]. I understand abortion is a touchy subject for some people, but it's not like I was advocating for or against abortion. After that, I posted a meme complaining about the lack of specificity of the rules on Lemmy and that post also got removed. That's enough to let me... Source: almost 3 years ago
  • This whole lemmy universe has me quite confused, but I would like to utilize it. seeking assistance
    Im using the Jeroba app on android first of all. It just seems like lemmy is a complete and total mess. So many contradicting things Im seeing. And then theres instances and communities but apparently it "doesn't matter what instance you choose because you'll still have access to all other communities anyway". Well that is pretty much false. Like using lemmy.world for example. I'll search up for a linux community... Source: almost 3 years ago
  • Iโ€™m a fan of Squabbles, but the constant circlejerk over the developer is turning me off the site
    Signing up isn't complicated, people just get confused by what "federation" means... It doesn't matter what instance (or "server" if it's easier to understand) you sign up for. I'm on lemmy.world but I post and comment on lemmy.ml and 10-15 other instances all the time. Think of instances as "copies" with different users and posts, but they all interact with each other (with a few exceptions). Source: about 3 years ago
  • I'm so lost. Is there an easy mode to the fediverse?
    Whereas the top three on my subscribed feed are from [Games@lemmy.world](mailto:Games@lemmy.world), [gaming@lemmy.ml](mailto:gaming@lemmy.ml) and [gaming@beehaw.org](mailto:gaming@beehaw.org). My subs on lemmy are mostly related to video games, but this points out something that confuses some folks coming over from Reddit - lemmy.ml and beehaw.org both have communities named "gaming" and they are separate...
