## 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

## Zapdroid Extension

Zapdroid Extension is a Chrome browser add-on built around one narrow idea: remove writer's block while you are already typing. Instead of switching to a separate writing app or chatbot tab, you call up the extension and it returns creative, contextually aware suggestions that you can adapt into emails, articles, essays or marketing copy.

The tool is distributed through the Chrome Web Store under the developer's own website (zapdroid.io) and is published as a free extension. The current listing shows version 2.2.2, last updated in April 2025, and a small user base, so it is best treated as a lightweight helper rather than a full writing suite. The developer declares that the extension does not collect its users' data.

Because it stays inside the browser, Zapdroid fits naturally into existing workflows — drafting replies, brainstorming angles for a blog post, or polishing a paragraph — without any account setup or installation beyond clicking "Add to Chrome".

**Pricing & Plans:** Free. The Chrome Web Store listing installs at no cost and shows no paid tiers or in-app purchases.

- **Inline AI writing suggestions:** Generates creative, contextually relevant text for whatever you are drafting, from emails to essays.
- **Runs inside the browser:** Delivered as a Chrome extension, so you can get suggestions without leaving the page or opening another app.
- **Multiple content formats:** Suited to emails, articles, essays and general short-form copy rather than a single fixed template.
- **No cost to install:** Free to add from the Chrome Web Store with no subscription shown on the listing.
- **Privacy-conscious design:** The developer declares that user data is not collected, sold, or used for unrelated purposes.

**Strengths:** Free Chrome extension with no listed subscription; Works inline in the browser, so no separate app is needed; Covers several formats: emails, articles, essays and copy; Developer states no user data is collected or sold

**Limitations:** Very small user base and no ratings on the listing; Only available for Chrome-based browsers; Last update was April 2025, so the feature set is static; No published pricing, API or team features to scale with
