## ForthWrite

ForthWrite is an AI writing assistant aimed at people who live in their inbox. 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

## RK Email Assistant

RK Email Assistant — branded RKMail in its store listing — is a lightweight Chrome extension that plugs into Gmail and helps you deal with a busy inbox. The pitch is straightforward: rather than typing every reply from scratch, you let the extension draft a response for you and then send or tweak it. The listing claims this makes replying roughly ten times faster, and it emphasizes the low effort of a few clicks per message.

This is a third-party tool: it is published by an independent developer (rkmail-extension.com, contact rakib@rkdevelopers.co.uk), so it is not an official Google or Gmail add-on. The listing notes that it offers in-app purchases, meaning some capability sits behind a payment, while the extension itself is free to try. It was last updated in March 2023 and shows modest adoption with a small user base and a single rating, so it is best treated as a small, focused utility rather than a heavily maintained platform.

Because the extension runs inside the browser, its value depends on how well it integrates with your existing Gmail workflow. If you send a lot of similar or routine emails, an AI drafting layer can save real time; if your mail is highly bespoke, expect to edit the drafts. Note that the extension declares it handles personally identifiable information and personal communications, so review the privacy disclosure before granting access.

**Pricing & Plans:** Free to try, with in-app purchases available according to the Chrome Web Store listing. No specific price points are published in the listing.

- **AI reply drafting in Gmail:** Generates email responses inside your Gmail inbox using advanced language models.
- **Few-click workflow:** Reply to emails with just a few clicks instead of typing each message from scratch.
- **Busy-inbox focus:** Built for people managing high volumes of routine email who need to keep up.
- **Lightweight Chrome extension:** Installs into Chrome as a small extension rather than a separate app.
- **In-app purchases:** Offers optional paid functionality beyond the free trial, per the store listing.

**Strengths:** Works directly inside Gmail via Chrome; Cuts time on routine, repetitive replies; Free to try with optional paid features; Small, focused extension with low setup overhead

**Limitations:** Last updated in March 2023, so it may lag newer Gmail changes; Small user base and a single rating in the store listing; Handles personal communications and PII, so privacy review is needed
