## 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

## Cosmo AI

Cosmo AI is a browser-native AI assistant rather than a standalone chatbot. Once installed, it adds a side panel and inline helpers to Chrome, so the assistant travels with you from site to site. The pitch is simplicity: instead of copying text into a separate AI tool and pasting the result back, you ask Cosmo directly on the page you are reading and use the output where you need it.

The feature set is aimed at everyday knowledge work. You can hold a general conversation with the assistant, generate long-form or social content, draft tweets with suggested hashtags, write replies to email, and produce LinkedIn posts such as hiring notices or company milestones. A select-and-ask behaviour lets you highlight a passage on any site and request a summary or explanation of just that text.

Cosmo AI is published by Nordfjord Limited and has been updated steadily through 2025. It is a lightweight extension, installs in a click, and is positioned as a general productivity layer for people who spend their working day inside the browser rather than in a dedicated writing app.

**Pricing & Plans:** Free to install as a Chrome extension, with optional in-app purchases (freemium). Specific tier prices are not published on the store listing.

- **In-browser AI chat:** Open a chat panel on any website and ask questions, brainstorm ideas or get quick information without leaving the page.
- **Content and copy generation:** Turn a rough idea into blog paragraphs, marketing copy or product descriptions directly inside the tab where you are working.
- **Tweet composition and hashtag ideas:** Draft complete posts, generate hashtags and brainstorm angles for X/Twitter, then publish when you are happy with the wording.
- **Email reply drafting:** Generate ready-to-send replies for incoming messages so clearing an inbox takes minutes instead of an afternoon.
- **Select-and-ask anywhere:** Highlight any text on any site — an article, a spec, a contract snippet — and let Cosmo summarise or explain it in place.
- **LinkedIn post generation:** Produce hiring announcements, milestone posts and launch updates sized for LinkedIn's format with a single click.

**Strengths:** Works on top of whatever website you are already on, so there is no context switching; Covers several everyday writing jobs — social posts, emails, LinkedIn content, instant answers — in one extension; Very small install (around 1.6 MB) and a one-click setup; Actively maintained: the publisher has shipped updates through 2025

**Limitations:** Child of the browser: it only runs as a Chrome extension, so it is useless in Safari, Firefox or mobile browsers; Ratings volume is thin (a handful of reviews), so it is hard to judge long-term reliability; No published price list on the store page; costs show up only as in-app purchases; Generated drafts still need a human edit before you post them publicly
