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.

Redox features and specs

  • Security
    Redox is designed with security in mind, leveraging the Rust programming language which is known for its memory safety features, reducing common vulnerabilities such as buffer overflows.
  • Modern Language
    It's built in Rust, a modern programming language celebrated for its performance and safety, which brings modern development principles and community support to the OS.
  • Microkernel Architecture
    Redox utilizes a microkernel architecture, which can offer increased stability and robustness by running most services outside of the kernel, reducing the risk of system crashes.
  • Open Source
    Redox is open source, allowing developers to examine, modify, and contribute to the project, fostering transparency and collaboration.
  • UNIX-like Interface
    Redox provides a familiar environment for UNIX users with a similar command line and system interface, making it easier for developers accustomed to UNIX systems to adopt.

Possible disadvantages of Redox

  • Maturity
    Redox OS is still in its early stages of development, lacking the maturity and stability found in more established operating systems like Linux or Windows.
  • Application Support
    The limited ecosystem means fewer applications are available or compatible with Redox, making it less practical for daily use compared to mainstream operating systems.
  • Hardware Compatibility
    Since it's a relatively new OS, Redox may not support as wide a range of hardware compared to more established operating systems, potentially limiting its usability on certain devices.
  • Community Size
    While the Rust community is growing, Redox itself has a smaller user and developer base, which can impact the speed of development and availability of community support.
  • Performance
    Microkernel architectures can have performance overheads due to the context switching between kernel and user space, potentially impacting the efficiency of the OS.

Analysis of Redox

Overall verdict

  • Redox OS is a promising and innovative project, particularly appealing to developers and enthusiasts interested in systems programming, Rust, and security-focused environments. However, as a relatively young project compared to mainstream operating systems, it may lack comprehensive driver support and application compatibility.

Why this product is good

  • Redox OS is an open-source operating system written in Rust, which provides memory safety and prevents common bugs that occur in languages without these safety features. It is microkernel-based, making it more modular and secure. The emphasis on safety and modularity is ideal for environments where security and reliability are paramount.

Recommended for

  • Developers interested in Rust and systems programming
  • Security-conscious users looking for safer operating systems
  • Enthusiasts interested in exploring new and innovative OS projects
  • Academics and researchers studying operating system design

Questions & Answers

As answered by people managing Redox 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)
