## 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

## WriteSharp

WriteSharp is a browser extension focused on one job: making the text you type online sound clearer and more professional. When you highlight a sentence in a web form, email client, or social media box, WriteSharp sends it to an AI model, returns an improved version, and displays the original and the rewrite next to each other so you stay in control of what changes.

The extension supports custom prompts, so rather than accepting a single generic rewrite you can describe what you want — shorter, friendlier, more formal — and the AI adjusts accordingly. You can also hand-edit the suggestion before inserting it back into the page, making it a review-and-approve workflow rather than an automatic overwrite.

WriteSharp runs as a privacy-conscious tool: text is processed through your own OpenAI API key, which you supply in the settings, and the developer states that no user data is collected or sold. It works on many common email and social platforms, though the developer notes it is not compatible with complex editors such as Google Docs, Microsoft Office Online, or Google Sheets because of how those apps render their documents.

**Pricing & Plans:** The extension itself is distributed through the Chrome Web Store at no charge, but it requires your own OpenAI API key, so you pay OpenAI directly for the model calls you make. There is no separate WriteSharp subscription.

- **Inline text refinement:** Highlight any text on a supported page and get a clearer, more professional AI rewrite without leaving the browser tab.
- **Side-by-side comparison:** The original and improved versions appear together, so you can see exactly what the AI changed before accepting it.
- **One-click insertion:** Edit the suggestion if needed, then drop the polished text straight back into the page with a single click.
- **Custom prompts:** Tell the AI how you want the text changed — shorter, warmer, more formal — to tailor the rewrite to your audience.
- **Bring your own API key:** Text is processed through an OpenAI key you control, with the developer declaring no collection or sale of your data.

**Strengths:** Very simple, single-purpose workflow that fits into any web form; Side-by-side view keeps you in control of every change; Custom prompts let you steer tone and length; You use your own API key, so there is no extra subscription

**Limitations:** Requires an OpenAI API key and a paid OpenAI account to function; Does not work with Google Docs, Office Online, or Sheets; Small user base and no ratings, so long-term support is unproven
