## 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

## Ghostwriter AI for Microsoft Office

Ghostwriter targets people who live inside Microsoft Office rather than in a separate chat window. Instead of copying text back and forth between Word and a chatbot, you install the add-in from the Office Add-in Store and call up AI actions on a selection, a document or a table. Each edition ships its own set of Quick Action prompts, personas and style controls, so a student, a litigator and a novelist each get a tailored starting point.

The product line is deliberately modular. Ghostwriter Word comes in Basic, PRO and Ultimate tiers, with Ultimate adding an interactive interface and support for the latest reasoning models. Separate editions exist for Outlook email drafting, Excel data analysis and sample-data generation, and PowerPoint bullet generation. There are also vertical editions for authors and legal professionals that add role-specific prompts, genre and document-type templates.

Pricing is a one-time purchase per user key rather than a subscription, and the add-in itself does not include model usage. You supply your own API key from OpenAI, Google Gemini or xAI Grok, which means generation costs are billed by the model provider directly. The developer emphasises a privacy-first posture, stating a commitment to not treat users as the product. The site is a single-developer operation, so support runs by email and product keys can take around an hour to arrive after purchase.

**Pricing & Plans:** One-time purchase per edition, no subscription: Word Basic $50, Word PRO $100, Word Ultimate $150, Outlook $50, Excel $50, PowerPoint $50, Office Bundle (all four apps) $200, Author Edition $100 and Legal Edition $250 (USD). Model usage is not included — you connect your own OpenAI, Google Gemini or xAI Grok API key and pay that provider separately.

- **Native Office add-ins:** Works inside Word, Excel, Outlook and PowerPoint on Windows, Mac, the web and iPad through the Microsoft Office Add-in Store.
- **Bring your own model key:** Unlock OpenAI, Google Gemini or xAI Grok models with your own API key, so you control provider choice and usage spend.
- **Personas, prompts and styles:** Editions ship with Quick Action prompts, agent personas, writing styles and tones, creative-level and response-length controls.
- **Spreadsheet and slide generation:** Ask Ghostwriter Excel to analyse a selected table, generate sample data, or have Ghostwriter PowerPoint produce quick bulleted facts.
- **Profession-specific editions:** Dedicated Author and Legal editions add publishing genres, writing styles and legal document types for those workflows.

**Strengths:** One-time pricing instead of a recurring subscription; Runs inside the Office apps most teams already pay for; Bring-your-own API key gives control over model choice and cost; Multiple vertical editions tuned for authors, legal and students

**Limitations:** Model API costs are extra and must be set up by the user; Licences are single-user keys, so team management is manual; Product keys can take up to an hour to be delivered by email
