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.

Wicked PDF features and specs

  • Ruby on Rails Integration
    Wicked PDF is specifically designed to integrate seamlessly with Ruby on Rails applications, making it a popular choice for developers working within this framework.
  • Customization Options
    The library allows for extensive customization, providing options to modify the layout and design of the PDF, such as margins, headers, and footers.
  • HTML to PDF Conversion
    Wicked PDF efficiently converts HTML content to PDF using the powerful wkhtmltopdf tool, allowing developers to leverage their existing HTML/CSS skills.
  • Active Community Support
    Being an open-source project, Wicked PDF benefits from an active community that contributes to its improvement and provides support through discussions and shared solutions.
  • Embedded Resource Support
    It supports the embedding of images, CSS, and JavaScript in the rendered PDFs, facilitating the creation of dynamic and interactive PDF documents.

Possible disadvantages of Wicked PDF

  • wkhtmltopdf Dependency
    Wicked PDF relies on the wkhtmltopdf external binary, which may require additional installation and configuration on the server to function properly.
  • Limited Vendor Support
    As an open-source solution, Wicked PDF may not offer the same level of professional support or SLA guarantees that a proprietary library might provide.
  • Complex CSS Handling
    Rendering complex CSS or JavaScript-heavy pages might be challenging due to wkhtmltopdf's limitations or differences in how it interprets styles.
  • Performance Overhead
    Generating PDFs using wkhtmltopdf can be resource-intensive, leading to potential performance overheads, especially for large-scale applications generating many PDFs concurrently.
  • Cross-Platform Compatibility
    Ensuring consistent behavior across different operating systems can be tricky, as wkhtmltopdf's performance and features vary slightly between platforms.

Questions & Answers

As answered by people managing Wicked PDF 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)

    My first contact with building PDFs was with rails using https://github.com/mileszs/wicked_pdf. The task always seems easy, you just build HTML and render that to pdf. And in fact, the part of rendering the info to the pdf is easy. The nightmare comes when implementing what is on the mockups. How will CSS behave in printing mode?

  • Creating PDFs in a Ruby on Rails application
    You have a few options when trying to create a PDF in a Rails environment. Prawn and Wicked PDF have been around for quite a while. I have been using both gems and they work fine. However, they have a few limitations that can make it difficult to handle more complex PDFs. I recently discovered Grover, which can remediate some of this inflexibility in creating PDFs. - Source: dev.to / almost 5 years ago
  • Converting HTML to PDF using Rails
    A couple of popular gems to convert HTML to PDF in Rails are PDFKit and WickedPDF. They both use a command line utility called wkhtmltopdf under the hood; which uses WebKit to render a PDF from HTML. - Source: dev.to / about 5 years ago
