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

AFFiNE's answer
AFFiNE is unique because it combines flexibility with strong privacy protections, making it ideal for users who value both control over their workspace and data security. The platformโs canvas feature allows for a highly customizable layout, enabling users to visually organize information in a free-form, drag-and-drop manner. This flexibility supports diverse workflows, from brainstorming and project planning to note-taking and task management, making AFFiNE a versatile tool adaptable to personal and professional needs.
What sets AFFiNE apart even further is its commitment to privacy with a local-first approach. This means data is stored locally on usersโ devices, safeguarding sensitive information and ensuring full offline access. As an open-source platform, AFFiNE also invites community contributions and customization, allowing users to shape the tool to fit their specific requirements. This blend of privacy, flexibility, and user-driven development creates a truly unique productivity solution.
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.
ForthWrite's answer:
Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API
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.
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.
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.
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.

I'd say Affine or Obsidian. Obsidian is built on-top of just markdown files, so you can do whatever you want with them. E.g. If you need multiplayer editing you could use 3rd party solutions or even something like HedgeDoc. Affine is more closer to Notion and self-hostable.

I wrote a more detailed comparison of Notion vs Obsidian here: https://bryanhogan.com/blog/notion-obsidian-comparison I kinda dislike where Notion is heading though, forcing more and more things on their users without any ways to disable them. But yes, it's capable to do what you are looking for. Maybe Affine could also work though, you can self-host it and it's more customizable: https://affine.pro/. - Source: Hacker News / 3 months ago
AFFiNE is a workspace that merges docs, whiteboards, and databases into one tool. The editor supports block-based writing similar to Notion, but adds an infinite canvas (whiteboard) mode where blocks can be freely positioned. It's built with TypeScript/React and uses PostgreSQL and Redis for the self-hosted backend. - Source: dev.to / 5 months ago
I made the jump to AFFiNe (https://affine.pro/) a few months ago and have really liked using it. I am able to self host and have found it to be a _nearly_ 1:1 replacement for Notion. Affine's database implementation isn't nearly as nice though - but they are workable and they are improving. My biggest gripe is that the OSS project is very oriented around a hosted product rather than the self hosted - so things... - Source: Hacker News / 11 months ago
Affine : https://affine.pro/ You can self host too if you like. Not all features as Notion but comes very close. Seems more private too compared to Notion. I am also looking for more private and secure Notion alternatives. My company doesnโt allow using Notion. I like templates, tasks, scrum etc. Which I use for personal use. But I am reluctant on saving any personal information in it. - Source: Hacker News / about 1 year ago
