About

ForthWrite is an AI email writer that drafts replies in your voice, right inside Gmail and Outlook. Open any thread, and your reply is already sitting there, sounding more like you with every email you send. Instead of producing a generic “professional tone” reply, ForthWrite learns from your real sent emails, capturing tone, sentence rhythm, sign-offs, terminology, and the edits you make over time. Click Generate Draft, get a polished reply in your voice, edit if needed, and send; every accepted draft and sent reply becomes part of a private writing profile unique to you. ForthWrite is built for people who care how their email reads, especially when messages need to feel personal, precise, and not templated. It works inside Gmail and Outlook Web, supports both work and personal inboxes, and lets users keep drafting without switching tabs or copying prompts into a separate AI tool.

About

Sinceerly is a lightweight AI-powered “humanizer” designed to reverse the polished, formulaic tone of AI-generated writing and make emails feel more natural, imperfect, and authentically human. Positioned as the opposite of traditional writing assistants, it integrates directly into Gmail as a Chrome extension, allowing users to draft emails normally and then transform them with a single click. It focuses on removing common AI writing signals, such as em dashes, repetitive phrases like “not just…,” and overly structured language, replacing them with simpler wording, abbreviations, and intentional imperfections. It introduces controlled variability through a single slider with three intensity levels, each progressively altering tone, structure, and formatting to mimic real-world communication styles. Users can preview all edits through highlighted changes and selectively apply them, maintaining control over the final message.
