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.

Bitcoin features and specs

  • Decentralization
    Bitcoin operates on a decentralized network, which means no single entity controls it. This reduces the risk of systemic failures and central authority misuse.
  • Transparency
    All transactions are recorded on a public ledger called the blockchain, providing transparency and making it difficult to commit fraud.
  • Lower Transaction Fees
    Bitcoin transactions often have lower fees compared to traditional banking systems and can be more cost-effective for international transfers.
  • Limited Supply
    Bitcoin has a capped supply of 21 million coins, which can potentially preserve its value over time, making it an attractive investment.
  • Security
    Bitcoin transactions are secured by cryptographic algorithms, making them very difficult to tamper with or hack.
  • Accessibility
    Bitcoin provides financial services to unbanked and underbanked populations, offering a means of transferring and storing wealth.

Possible disadvantages of Bitcoin

  • Volatility
    Bitcoin's price can be highly volatile, making it a risky investment and potentially unsuitable for low-risk tolerance individuals.
  • Scalability
    Bitcoinโ€™s network can struggle to handle a high number of transactions simultaneously, leading to slower transaction times and higher fees.
  • Regulatory Risk
    Governments around the world are still determining how to regulate Bitcoin, posing potential regulatory risks which can impact its use and value.
  • Irreversible Transactions
    Once a Bitcoin transaction is made, it cannot be reversed. This can be a disadvantage if a mistake is made or in cases of fraud.
  • Energy Consumption
    Bitcoin mining requires significant computational power and energy, raising concerns about its environmental impact.
  • Adoption and Acceptance
    While growing, Bitcoin is not universally accepted and its usability as a currency is still limited compared to traditional forms of money.

Analysis of Bitcoin

Overall verdict

  • Bitcoin's potential as a financial tool and asset largely depends on individual perspectives on risk, market volatility, and the desire for alternative financial systems. It can be a good choice for those aligned with these principles but comes with significant volatility and risks.

Why this product is good

  • Decentralization: Bitcoin is decentralized, meaning it's not controlled by any government or financial institution, which attracts users who value financial independence.
  • Limited Supply: Bitcoin has a capped supply of 21 million coins, resulting in scarcity that proponents argue could lead to increased value over time.
  • Security: Bitcoin's blockchain technology is considered highly secure, making it a reliable store of value.

  • Advocates of Decentralization: Individuals who support decentralized financial systems and want to participate in alternative economic models.

Questions & Answers

As answered by people managing Bitcoin 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)
