Questions & Answers

As answered by people managing Mizage Divvy 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)

  • Ghostty Is Leaving GitHub
    I like Divvy because it supports more than just halves and quarters โ€” I use a 7ร—6 grid so my browser can be wider than my editor and terminal, and my editor taller than my terminal: https://mizage.com/divvy/ Pairs well with Stay to make windows automatically return to their assigned layout when plugging/unplugging my external display: https://cordlessdog.com/stay/. - Source: Hacker News / 2 months ago
  • HopTabโ€“free,open source macOS app switcher and tiler that replaces Cmd+Tab
    Divvy handles this very well. It's been my go-to for like fifteen years: https://mizage.com/divvy/. - Source: Hacker News / 4 months ago
  • Rift โ€“ a tiling window manager for macOS
    Personally, I really like how Divvy (https://mizage.com/divvy/) uses a modal (press cmd-alt-ctrl-x, then press a single key to chose a layout for the frontmost window), but it's no longer maintained. - Source: Hacker News / 9 months ago
  • Rift โ€“ a tiling window manager for macOS
    Similar experience and pov here -- but w/ Divvy^1 (not Rectangle). 1. https://mizage.com/divvy/. - Source: Hacker News / 9 months ago
  • Loop: Open-Source macOS Window Manager
    I am a big fan of Divvy (https://mizage.com/divvy/)โ€”while both dated and paid, it has a wonderful feature of a visual tile map you can use. In all other cases I know, there are a bunch of shortcuts to make a window upper-top or something. But in many cases, it is not enough, as I need fine-grain control. - Source: Hacker News / about 2 years ago
