## 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

## Gmail GPT Assistant

Gmail GPT Assistant is one of the earliest wave of Gmail add-ons built on top of OpenAI's language models. It was created by independent developer Clément Duveau and published as an open-source project, with the complete code available on GitHub. The mechanism is deliberately minimal: a new button appears in Gmail, it reads the email you want to answer, and it pastes an AI-generated reply into a fresh draft.

Because the code is public, this extension appeals to people who want to see how an AI email assistant works under the hood before trusting it with their inbox. The scope is narrow compared with commercial alternatives - there is no template library, no translation panel, no summary feature. It does one job: turn an incoming message into a starting draft.

The trade-off is maturity. The store listing shows version 0.2, last updated in March 2023, with a very small user base and no ratings yet. That is not evidence the extension is broken, but it does mean the project has not been actively modernised as newer, cheaper and faster OpenAI models arrived. If you value transparency and a single-purpose tool over breadth of features, it still does exactly what it promises.

**Pricing & Plans:** Free extension. The Chrome Web Store listing is in the Contact for Pricing model only because the developer supplies no commercial tiers; usage depends on your own OpenAI access.

- **Draft replies from an open thread:** Click the extension button on any message and it generates an answer based on the previous email in the thread.
- **Automatic draft creation:** A new Gmail draft is opened for you with the generated text already pasted in, ready for editing.
- **Open-source codebase:** The full source is public on GitHub, so you can inspect exactly what the extension sends and how it works.
- **Bilingual interface:** The listing ships with English and French localisation.

**Strengths:** Completely free to install with no subscription tier; Open-source code you can audit on GitHub; Extremely simple workflow: one button, one draft, one paste; Lightweight at roughly 1 MB

**Limitations:** Last updated in 2023 and built around the older GPT-3 / DaVinci generation; Tiny user base and no ratings makes quality harder to judge; No templates, translation, summarisation or other conveniences
