Questions & Answers

As answered by people managing SomaFM 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)

  • The lost joy of music piracy
    Can I offer you a SomaFM[0] in these trying times? They're entirely listener supported and the music they play is - to my knowledge - entirely human curated. I've found many tracks and artists new to me, with some artists not even having a presence (or a very small one) on Spotify. Their curation is so good that they've become a significant resource I go to when seeking out new music. It feels like a warm hug from... - Source: Hacker News / 6 days ago
  • Music for Programming
    For programming, I cannot recommend Soma FM [1] highly enough. There are a huge number of stations, most lyric-free (as to reduce the potential for flow interruption). [1] https://somafm.com/. - Source: Hacker News / 4 months ago
  • First, Make Me Care
    Check out KEXP and SomaFM. KEXP in particular is a great way to discover new music that you might not normally listen to. https://www.kexp.org/ https://somafm.com/. - Source: Hacker News / 6 months ago
  • How Spotify Made Me Self Host
    My other favorites, especially for coding, are SomaFM (Groove Salad or DEFCON substations)[1] and SceneSAT[2]. [1] https://somafm.com [2] https://scenesat.com/. - Source: Hacker News / 7 months ago
  • Radio Garden
    Anyone looking for a commercial-free, listener-supported "radio" station would be remiss not to check out https://radioparadise.com -- it is truly a rare-gem in our over-commercialized world. And we can't talk about music streaming on the Internet without mentioning one of the originals -- https://somafm.com -- still going strong. I support both of these stations because their "business model" is so refreshing,... - Source: Hacker News / about 1 year ago
