## 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

## Prompt Engine Pro

Prompt Engine Pro tackles a very practical problem: writing replies takes time, and the blank cursor is intimidating whether you are answering a client, a recruiter or a match on a dating app. The extension sits in your browser and, when you need to respond, uses ChatGPT behind the scenes to draft a suggestion. Rather than generating text in a vacuum, it reads the conversation around the message — its context, tone and length — so the suggestion lands closer to what a real reply would sound like.

A distinctive part of the product is its response archive. Every ChatGPT-generated reply is saved into your Prompt Engine Pro account, which means you gradually build a personal library of messages you can revisit or adapt instead of regenerating answers from scratch. The extension also adapts to your own writing style, so the drafts converge on your voice rather than a generic AI register. Developers note that the tool does not collect or use your data, an unusual and welcome stance for an extension that handles private messages.

The extension is distributed through the Chrome Web Store under a freemium model, with roughly two thousand users, a 4.8 rating and a recent update. Its developer publishes it through jargonhandlers.com and home.promptenginepro.com. It is best understood as a lightweight communication accelerator rather than a full AI assistant: its job is to get a good first draft on screen fast.

**Pricing & Plans:** Prompt Engine Pro is offered as a freemium browser extension — free to install with paid tiers for expanded use. Check the Chrome Web Store listing and the developer's site for current pricing.

- **Context-aware reply suggestions:** The extension reads the tone, intent and length of the ongoing conversation so suggestions actually fit the exchange.
- **Style adaptation:** It adjusts to your writing style over time, so replies sound like something you would genuinely send.
- **Saved response library:** ChatGPT-generated responses are stored in your account, giving you a reusable archive of replies you can pull up later.
- **In-browser workflow:** Everything happens inside the page you are already on — no copy-pasting between tabs or separate dashboard.
- **Time-saving automation:** Removes the blank-page hesitation from messaging by offering a ready draft for every message you receive.

**Strengths:** Cuts the time spent drafting replies to everyday messages; Context-aware suggestions read tone and length, not just keywords; Saved-account response library turns one-off replies into reusable assets; Developer states the extension does not collect or use your data

**Limitations:** Nothing guarantees a suggested reply will be accurate or appropriate for sensitive conversations; Its value depends on how much time you spend writing messages in a browser; Developer is an individual publisher, so enterprise-grade support is unlikely
