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
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.
WorkLLM helps companies become AI-native by giving every team a shared AI brain for work. Instead of employees using AI in isolated chats and personal accounts, WorkLLM provides a central AI workspace connected to company knowledge, team workflows, AI tools, assistants, agents, and 200+ AI models.
With WorkLLM, teams can collaborate in shared AI threads, preserve important context through Organization Memory, create reusable AI tools for common tasks, and build custom AI assistants for departments such as marketing, sales, support, product, HR, and operations. The platform helps companies reduce repeated prompting, improve output consistency, retain institutional knowledge, and make AI easier to adopt across the organization.
WorkLLM is designed for companies that want to move beyond individual AI productivity and embed AI into daily workflows, decisions, and processes. From creating brand-safe content and sales emails to supporting onboarding, research, documentation, and internal knowledge sharing, WorkLLM helps teams work faster, stay aligned, and build intelligence that compounds over time.

ForthWrite WorkLLMForthWrite'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.
WorkLLM's answer:
WorkLLM gives companies a shared AI brain for work, combining organization memory, team AI workspace, reusable AI tools, custom assistants, AI agents, and 200+ AI models in one platform.
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.
WorkLLM's answer:
Most AI tools are built for individual productivity. WorkLLM is built for teams, helping companies preserve knowledge, reduce repeated work, create consistent outputs, and become AI-native.
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.
WorkLLM's answer:
WorkLLM is built for growing companies, startups, and teams across marketing, sales, support, product, HR, and operations that want to use AI across the organization.
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.
WorkLLM's answer:
WorkLLM was created after seeing that employees were using AI every day, but companies were not becoming smarter because knowledge stayed scattered across personal chats, tools, and documents.

WorkLLM's answer:
WorkLLM uses large language models, retrieval-augmented generation, AI agents, workflow automation, vector search, integrations with work applications, and secure cloud infrastructure.
WorkLLM's answer:
WorkLLM works with growing teams and early customers using AI across product, marketing, sales, support, and operations. Customer names are not publicly listed unless shared through approved case studies or references.
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.
