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.

  • 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.

Skeleton CSS features and specs

  • Lightweight
    Skeleton CSS is extremely lightweight, with a file size of just about 400 lines of code, making it quick to load and easy to manage compared to bulkier frameworks.
  • Simplicity
    Its simplicity makes it easy to learn and implement, which is ideal for beginners or for small projects that don't require complex styling.
  • Responsive Grid
    Skeleton CSS includes a responsive grid system, which helps in creating responsive layouts that easily adjust to various screen sizes.
  • Clean Design
    Skeleton offers a clean and minimal design by default, providing a good starting point for further customization without unnecessary bloat.

Possible disadvantages of Skeleton CSS

  • Limited Components
    Skeleton CSS lacks the range of components available in larger frameworks like Bootstrap or Foundation, making it less flexible for larger or more complex projects.
  • Customization
    While its simplicity is an advantage, it also means less out-of-the-box customization options compared to more comprehensive frameworks.
  • Community and Support
    Skeleton CSS has a smaller community and fewer resources or plugins available, meaning less peer and developer support is accessible compared to more popular frameworks.
  • Scalability
    It is less suited for large-scale applications where a more feature-rich and modular framework might be necessary to manage complex requirements.

Analysis of Skeleton CSS

Overall verdict

  • Skeleton CSS is a good choice for developers seeking a minimalist framework that provides essential styling without unnecessary complexity. It's particularly beneficial for small projects or when you need to rapidly prototype designs. However, for larger projects with extensive UI component requirements, a more comprehensive framework might be more suitable.

Why this product is good

  • Skeleton CSS is a lightweight CSS framework designed for simplicity and ease of use. It provides a flexible grid system and basic styles for common HTML elements, making it ideal for starting projects quickly without the overhead of more complex frameworks. Its minimalistic approach ensures that developers have a clean slate to work from, without being overwhelmed by pre-designed components or themes. Additionally, its simplicity makes it easy to learn and modify, which is great for developers who prefer more control over their project's appearance.

Recommended for

    Skeleton CSS is recommended for developers who appreciate a minimalist approach, those working on small to medium-sized projects, designers who want a lightweight starting point without a steep learning curve, and anyone looking to quickly prototype ideas without being bogged down by extensive styling rules or pre-existing themes.

Questions & Answers

As answered by people managing Skeleton CSS 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.

22 Best Bootstrap Alternatives & What Each Is Best For
Balance Functionality and Performance: High functionality might come with the cost of performance. For example, MUI is exceptional for material design, but it might be heavier compared to lighter frameworks like Skeleton. Strive for a balance between the functionality you need and the performance you can afford to sacrifice.

However, it's important to note that Skeleton lacks active maintenance, posing a significant drawback. Additionally, the security of the Skeleton website is currently questionable. Furthermore, its use of outdated markup for layout, such as floats and clear fixes, may present compatibility issues in modern web development environments.

    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)

    I had been using similar projects such as skeleton[0] and milligram[1] for small experiments such as repfl[2], and wanted to create something similar that I would find aesthetically pleasing and that would fit in as little space as possible.

    Here's my personal goto: Find some minimal CSS framework. My preference is Skeleton [0] or Bootstrap [1]. The key is just finding something minimal that works without too much fuss. Personally, I rather have a minimal framework provide 'responsiveness' so I don't have to worry about it but I also want it to get out of the way of anything I do. Use JQuery [2].

    I use an older css library called skeleton. Itโ€™s a utility framework that came out before css grid. It has a really nice and easy to use grid system built without css-grid. I had to get rid of the media queries to get it work but itโ€™s been great otherwise! Source: almost 4 years ago

    I use a minified and customised simple boilerplate / grid system based in skeleton (http://getskeleton.com/). It has no mediaqueries predefined, but the rules for each screen resolution are stated. I start making the website for computer screen formats (large resolutions) and end adapting up the design to phone screens. Source: almost 4 years ago
