## 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

## HyperWrite

HyperWrite positions itself as a predictive AI writing assistant that follows you across the web. Through its Chrome extension, it offers TypeAhead suggestions that complete sentences as you type inside Gmail, Google Docs, and other web editors, alongside AutoWrite for generating paragraphs from a short instruction. An email responder drafts full replies from a few keywords, which is a common productivity win for people who live in their inbox.

Beyond the assistant itself, the product ships a large library of pre-built tools covering rewriting, summarization, explaining complex topics in plain language, speeches, and more. Users can also assemble custom AI tools that chain steps together for repeated workflows. HyperWrite Scholar adds a research layer by searching scholarly articles and papers, so generated text can be grounded in current, citation-backed information rather than the assistant's memory alone.

Pricing is subscription-based with a free entry point alongside paid tiers. Paid plans increase the monthly AI message allowance, unlock custom personas that mimic your writing style, and give unlimited TypeAhead suggestions. Higher tiers remove the message cap entirely and provide early access to experimental writing and agent features.

**Pricing & Plans:** Freemium. A free tier introduces the assistant and a limited message allowance; Premium is listed around $19.99/month with 250 AI messages, citations, real-time info, and 3 custom personas; Ultra around $44.99/month adds unlimited AI messages, 10 personas, and early access to experimental features. Annual billing is available at a discount.

- **TypeAhead autocomplete:** Context-aware sentence completions appear as you type in Gmail, Google Docs, and other sites through the Chrome extension.
- **AutoWrite and rewriting tools:** Generate a paragraph from a short prompt or rewrite existing text in a new tone while preserving meaning.
- **Citation-backed research:** HyperWrite Scholar searches millions of scholarly articles so drafts can include factual, properly cited information.
- **Email responder:** Turn a few keywords into a complete, ready-to-send email reply without switching tabs.
- **Custom AI tools:** Build your own reusable AI tools that chain prompts and steps for recurring workflows.

**Strengths:** Works directly inside the browser via a Chrome extension, so no app switching; Combines writing help with citation-backed research in one subscription; Large catalog of ready-made tools plus custom tool building; Essays, emails, and rewrites share one account and one message allowance

**Limitations:** Message caps on lower tiers can be limiting for heavy users; Best autocomplete experience depends on using the Chrome extension; Full capabilities require a paid plan beyond the free allowance
