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.

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.

Questions & Answers

As answered by people managing SocialDeck and ForthWrite.

What's the story behind your product?

SocialDeck's answer

The project started when our team of social media enthusiasts noticed a growing "privacy gap" on Instagram. We realized that many people felt hesitant to view stories because of the social pressure of the "seen" notification. We built SocialDeck.ai to democratize access to public information, giving users the freedom to explore content without the fear of being tracked, all while maintaining a clean, ad-light interface that prioritizes user experience over profit.

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.

Why should a person choose your product over its competitors?

SocialDeck's answer

Users choose us because of three core advantages:

Safety & No Login: Most competitors eventually prompt for a login or contain malware; SocialDeck is 100% web-based and requires no personal data.

Original Quality: We donโ€™t compress images or videos. What you see and download is the original high-resolution content directly from Instagram's servers.

Stability: Our infrastructure is optimized to handle Instagram's frequent algorithm updates, ensuring the service remains functional while other tools often crash or go offline.

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?

SocialDeck's answer

Our primary audience consists of three main groups:

Privacy-Conscious Users: Individuals who want to keep up with friends or public figures without appearing in their "viewed" list.

Digital Marketers & Competitor Analysts: Professionals who need to monitor competitors' daily content strategies and saved highlights anonymously for market research.

Content Creators: Influencers looking for inspiration or wanting to save specific content assets from the public domain for mood boarding and trend analysis.

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 makes your product unique?

SocialDeck's answer

The uniqueness of SocialDeckโ€™s tool lies in its "Zero-Footprint" philosophy combined with extreme speed. Unlike many tools that require a browser extension or display intrusive ads, our viewer is a pure web-based solution. It offers a seamless, high-definition (HD) preview and download experience that bypasses the need for an Instagram API login, ensuring that the userโ€™s identity remains 100% encrypted and hidden from the story creator's "seen" list.

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.

Which are the primary technologies used for building your product?

SocialDeck's answer

We utilize a modern, scalable tech stack to ensure high performance:

Backend: Node.js and Python-based scraping engines designed for high-concurrency and real-time data fetching.

Frontend: React.js for a fast, responsive, and mobile-friendly UI.

Cloud Infrastructure: AWS (Amazon Web Services) for global CDN delivery, ensuring low latency regardless of the user's location.

Security: Advanced SSL encryption and automated proxy rotation to ensure anonymous requests and protect user privacy.

ForthWrite's answer:

Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API

Who are some of the biggest customers of your product?

SocialDeck's answer

While we respect the privacy of our individual users and do not track specific identities, our tool is widely utilized by professionals at:

Independent Social Media Marketing Agencies

Freelance Content Strategists

E-commerce Brand Managers

Digital Journalism and Media Research Firms

Competitive Intelligence Consultants

    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)
