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.

MonoGame features and specs

  • Cross-Platform Support
    MonoGame allows developers to create games that run on multiple platforms (Windows, macOS, Linux, iOS, Android, and more) from a single codebase.
  • Open Source
    Being open-source, MonoGame is free to use and has a community-driven development process. Developers can contribute to its growth and adapt it to their needs.
  • Familiarity
    MonoGame retains the XNA framework's API, which is familiar to many game developers who have previously worked with Microsoft's XNA.
  • Extensive Documentation
    The MonoGame community has created extensive documentation, tutorials, and examples, making it easier for new developers to get started.
  • High Performance
    MonoGame is built with performance in mind, enabling developers to create games that run efficiently across different devices.

Possible disadvantages of MonoGame

  • Manual Resource Management
    Developers need to handle resource management manually, including loading and unloading assets, which can be cumbersome and error-prone.
  • Steep Learning Curve
    While it offers extensive support, new developers may find MonoGame's learning curve steep, especially those unfamiliar with game development or the XNA framework.
  • Lacks Built-in Editors
    Unlike some game engines, MonoGame does not come with built-in level or asset editors. Developers must rely on third-party tools or create their own.
  • Limited High-Level Features
    MonoGame offers a more low-level framework compared to some other engines like Unity or Unreal Engine, lacking advanced built-in features such as physics engines or advanced AI systems.
  • Community Dependency
    As an open-source project, MonoGame's development and support heavily depend on its community. This can result in slower updates and potentially less reliable support compared to commercial engines with dedicated support teams.

Questions & Answers

As answered by people managing MonoGame 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)

  • Rust Dependencies Scare Me
    To be fair, there is no language that has a framework that contains all of these things... Unless you're using one of the game engines like Unity/Unreal. If you're willing to constrain yourself to 2D games, and exclude physics engines (assume you just use one of the Box2D bindings) and also UI (2D gamedevs tend to make their own UI systems anyway)... Then your best bet in the C# world is Monogame... - Source: Hacker News / about 1 year ago
  • Free high-performance cross-platform game engine
    Defold has been there for a while, not sure of why this in on the front page right now. Anyways, Defold is good, the community, docs etc. Are on the lower side as compared to Godot. The other options include MonoGame https://monogame.net/ (Stardew Valley was written in it) and of-course the biggies like Unity or Unreal. A lot depends on how much investment in learning one wants to make, what is the feature set one... - Source: Hacker News / about 1 year ago
