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.

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

  • 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.

Krotos Studio features and specs

  • Real-time sound design
    Krotos Studio enables real-time sound design and audio creation, allowing users to generate and manipulate sounds on the fly rather than relying solely on pre-recorded samples, which significantly speeds up the creative workflow.
  • Intuitive interface for complex sound creation
    The software provides a user-friendly interface that simplifies the process of creating complex, layered sounds. Users can combine multiple sound sources, apply effects, and sculpt audio without needing deep technical expertise in synthesis or DSP.
  • AI and intelligent sound matching
    Krotos Studio incorporates intelligent features and AI-assisted tools that help users find and match sounds quickly, making it easier to achieve desired results and reducing the time spent manually searching through large sample libraries.
  • Versatile for game audio and post-production
    The tool is well-suited for multiple professional workflows including game audio, film post-production, and animation, offering flexible integration that appeals to sound designers across different industries.
  • Powerful layering and modulation capabilities
    Krotos Studio offers robust layering, modulation, and randomization features that allow sound designers to create unique, dynamic, and evolving sounds that avoid the repetitive quality of static samples.

Possible disadvantages of Krotos Studio

  • Steep learning curve for advanced features
    While the basic interface is approachable, mastering the more advanced features such as complex modulation routing and real-time performance controls can require significant time and effort, especially for users new to sound design.
  • Relatively niche user base
    Compared to mainstream DAWs and audio tools, Krotos Studio has a smaller community, which means fewer tutorials, third-party resources, and community-driven support are available online for troubleshooting and learning.
  • Cost may be prohibitive for hobbyists
    The pricing of Krotos Studio and its associated products can be significant, particularly for independent creators, hobbyists, or students who may find it difficult to justify the investment compared to free or lower-cost alternatives.
  • System resource demands
    Real-time sound generation and processing with multiple layers and effects can be CPU-intensive, potentially causing performance issues on older or less powerful systems, especially when used alongside other plugins in a DAW session.
  • Limited traditional sample library approach
    Krotos Studio is primarily designed around procedural and real-time sound generation rather than functioning as a traditional sample library player. Users who prefer browsing and triggering pre-made sounds may find the workflow less intuitive than dedicated sample management tools.

Questions & Answers

As answered by people managing Krotos Studio 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)
