## Compose AI

Compose AI is built around the idea that most knowledge workers write inside other applications, not inside a dedicated editor. It installs as a browser extension and layers autocomplete on top of ordinary text fields, so sentences finish themselves while you type in email, documents, forms, and chat windows. A generate feature covers the opposite case, where you want a full block of text produced from a short instruction.

A distinctive piece is personalization. Rather than emitting generic robotic phrasing, the assistant studies how you write and suggests phrasing that matches your voice, aiming to reduce the awkward, obviously-AI tone that general chatbots often produce. Because the extension runs wherever text inputs exist, there is no per-app integration to configure and no workflow to migrate.

The product follows a freemium structure. The core extension is free to use indefinitely, and a premium tier adds advanced features including parts of the personalization engine. The company reports that more than 400,000 individuals and over 10,000 teams use it. It is aimed at people who write constantly — sales, support, recruiting, and anyone whose day is dominated by email and documents.

**Pricing & Plans:** Compose AI is freemium. The Chrome extension and core autocomplete are free forever, with a premium subscription unlocking advanced features such as parts of the personalized writing engine. Team plans are available on request.

- **Autocomplete everywhere:** Finish sentences inline in any text field across your browser, from email clients and docs to chat and CRM tools.
- **Generated drafts on demand:** Produce full paragraphs, replies, or documents from a short prompt without leaving the page you are working on.
- **Personalized writing voice:** The engine learns how you write and suggests phrasing that sounds like you rather than generic AI output.
- **Zero workflow change:** Works as a browser extension, so there is no new app to adopt and no per-tool setup for the sites you already use.
- **Team and business use:** Individual and team plans make the assistant available across an organization's shared writing workflows.

**Strengths:** Works inside the apps you already use instead of adding another destination to check; Holds a large user base, with 400,000+ individuals reported, suggesting a mature and stable extension; Free tier covers everyday autocomplete, so value can be tested with no cost; Personalization features target your own tone rather than producing noticeably generic AI text

**Limitations:** Browser-extension form factor means it is limited to environments where you can install extensions; Personalization and advanced generation sit mostly behind the paid tier; Autocomplete suggestions still need review for accuracy in specialised or technical writing

## 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
