ForthWrite is an AI-powered email writing assistant that helps professionals draft emails that sound like they actually wrote them. Unlike traditional AI email tools that generate generic responses, ForthWrite continuously learns from your sent emails and editing patterns to create replies that closely match your personal writing style. It integrates directly with Gmail and Outlook through a Chrome extension, allowing users to generate context-aware email drafts without leaving their inbox.
Designed for business professionals, executives, sales teams, consultants, recruiters, founders, and anyone who spends significant time managing emails, ForthWrite aims to reduce inbox workload while maintaining authentic communication. As users continue editing and sending emails, the AI refines its understanding of their tone, vocabulary, greetings, sentence structure, and writing habits, producing increasingly personalized drafts over time.
Features
AI Voice Matching
ForthWrite analyzes your previously sent emails to understand your tone, writing style, greetings, sign-offs, sentence rhythm, and phrasing. Every new draft becomes more personalized as the AI continues learning from your edits.
Context-Aware Email Drafting
The platform reads complete email threads, including forwarded messages and nested conversations, to generate replies that address every relevant point instead of responding only to the latest message.
Gmail & Outlook Integration
ForthWrite works directly inside Gmail and Outlook through a Chrome extension, allowing users to generate email drafts without switching applications. Setup typically takes only a few minutes.
Auto-Draft Emails
Pro users can enable automatic draft generation so replies are prepared in the background before opening an email thread, reducing response time significantly.
Batch Drafting
Generate replies for multiple email threads simultaneously, making inbox management much faster for professionals handling large volumes of email.
Prompt Lab
The Prompt Lab lets users create, version-control, optimize, and A/B test custom prompts to improve AI-generated email quality for different communication scenarios.
Performance Analytics
Track metrics such as acceptance rate, similarity to your writing style, edit distance, and time saved. These insights help users measure how closely AI-generated drafts match their personal communication style.
AI Coaching
ForthWrite provides coaching reports that highlight how your writing style evolves and suggests improvements for more consistent communication.
Multiple AI Models
Users can choose from several leading AI providers, including OpenAI, Claude, Gemini, Grok, DeepSeek, Cohere, Mistral, Perplexity, and others. Advanced users can also connect their own API keys for greater flexibility and lower subscription costs.
Privacy & Security
The platform states that stored emails are encrypted, isolated to individual accounts, never shared with other users, and not used to train shared AI models. Users can export or delete their data whenever they choose.
