Instead of asking you to learn a new tool, it installs as a Gmail and Outlook web extension and adds a drafting widget directly to the compose box. On first use it analyses emails you have already sent to build a voice profile, so the very first suggested reply starts close to something you would actually send. The model is tuned for nuance and can also take a manual persona prompt when you want a specific register. The product family spans three levels. Inbox is the individual product, with a free tier that provides 10 AI drafts a week plus voice matching, and a Pro tier that unlocks auto-drafting, batch drafting of long threads, a Prompt Lab for versioning and A/B testing prompts, recipient- and intent-aware drafting, voice dictation, smart retrieval over your past mail, and performance analytics. Teams extends Pro drafting to every seat in an organisation with a shared voice baseline, a shared prompt library, a team analytics dashboard, and a review record showing what was drafted, what changed, and which model produced it. ForthWrite also sells consulting to professional-services firms such as accounting, tax, advisory, lending, and brokerage practices. Those engagements begin with a free 30-minute diagnostic and can extend into a paid audit, a 30-60 day roadmap, and implementation with written SOPs. The company is clear about its operating principle: ForthWrite drafts, and a person sends, so accountability and signature stay with the user. **Pricing & Plans:** Freemium with a free forever tier (10 drafts per week, voice matching, no card required), Pro at $24/month billed annually ($29 monthly), and Teams from $59/seat/month billed annually ($79 monthly, 2-seat minimum). All paid plans start with a 14-day free trial; Teams gets a 30-day trial. An optional Bring Your Own API Key mode takes roughly 17% off. Consulting is scoped separately per firm. - **Voice matching from your sent mail:** ForthWrite reads emails you have already sent to build a voice profile, then refreshes it roughly every 50 captured emails so drafts keep tracking how your writing evolves. - **Auto-draft and batch drafting:** Pro users can have replies waiting when they open Gmail, and clear dozens of threads in parallel instead of writing each one by hand. - **Recipient- and intent-aware drafting:** Drafts adapt tone to the person you are replying to and treat follow-ups, intros, and status updates as genuinely different jobs rather than one generic template. - **Prompt Lab and performance analytics:** Version control and A/B test your prompts, then track acceptance rate, voice match, and intent mix on a measurable improvement curve. - **Team standards and compliance guardrails:** On Teams, a shared voice baseline and shared prompt library keep every seat consistent, and a draft that breaks a firm rule stops the preparer with a written reason. **Strengths:** Drafts pick up your real tone because the voice profile is built from mail you have already sent; Works inside Gmail and Outlook web with no migration or new inbox to learn; Strong free tier with 10 drafts a week and voice matching included, no card required; Teams adds shared prompts, team analytics, and a review record that firms usually need **Limitations:** Web-based Gmail and Outlook only; there is no full desktop client experience; Full value depends on having a decent history of previously sent emails for the voice profile; Consulting engagements are custom-scoped, so pricing is not published [Profile (Markdown)](https://openaitools.app/tool/forthwrite.md) ## ReplaiGPT ReplaiGPT tackles a common annoyance with AI email tools: most assistants know nothing about who you are, so their drafts sound generic. ReplaiGPT makes you build reusable context profiles — details about yourself, your products, your standard answers — and then uses that stored context plus the currently open email to produce a reply that fits the actual request. The extension works directly inside Gmail. You click the ReplaiGPT icon on an open message, pick one of your saved contexts, choose a language, and hit Generate. The result appears in roughly 10–15 seconds and can be sent after a quick edit. It is aimed at people who answer the same kinds of recurring requests over and over and want a faster first draft. Privacy is handled locally: contexts and emails are stored in your browser rather than on ReplaiGPT's servers, and you supply your own OpenAI API key, so usage is billed by OpenAI directly. The basic version is free, with in-app purchases available. **Pricing & Plans:** Freemium. The basic version is free to use and requires your own OpenAI API key (billed by OpenAI). Optional in-app purchases unlock extra functionality. - **Custom context profiles:** Create and save reusable descriptions of yourself, your products or your business so every AI reply carries the right background. - **One-click Gmail replies:** Open a message, click the extension icon, select a context and generate a draft reply without leaving your inbox. - **Bring your own OpenAI key:** Connect your own OpenAI API key so generation costs go to your own account and you keep control of the model. - **Local-first privacy:** Emails and contexts stay in your browser instead of being stored on the developer's servers. - **Multilingual output:** Choose the language from the context dropdown and generate replies in any popular language. **Strengths:** Replies reflect your own context instead of generic AI phrasing; No server-side storage of emails — contexts stay in your browser; Works in any language and with your own OpenAI API key; Free basic tier with no upfront cost **Limitations:** Requires a separate OpenAI API key and account; Generation takes around 10–15 seconds per reply; Limited user base, so fewer community tips or reviews [Profile (Markdown)](https://openaitools.app/tool/replaigpt.md) ## Frequently Asked Questions ### How do ForthWrite and ReplaiGPT compare in monthly traffic?
