## 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

## Promptly

Promptly is distributed as a Chrome extension from Flipside Labs and targets a very specific frustration: knowing you have a powerful AI writer available but not knowing how to phrase the request that gets the best result. The extension bundles a collection of pre-written prompts covering everything from simple questions to more elaborate writing scenarios, so you always have a credible starting point.

The workflow is deliberately minimal. You install the extension, open your AI writing tool, and pull a prompt from the library. Because the prompts are pre-written, you spend less time inventing instructions and more time editing and refining the output. It is aimed at writers, marketers, and content creators who want to produce engaging content more efficiently without building their own prompt collection from scratch.

The Chrome Web Store listing describes Promptly as a tool that enhances AI writing software such as ChatGPT or Jasper by providing a collection of pre-written prompts. It is a small, focused utility rather than a full content platform, and the listing shows version 1.6, last updated February 22, 2023, with around 3,000 users. Promptly is an independent third-party extension and is not affiliated with ChatGPT, Jasper, or their parent companies.

**Pricing & Plans:** Free. The Chrome Web Store listing shows no paid tier or in-app purchase; the extension is installed at no cost.

- **Predefined prompt library:** A curated set of pre-written prompts you can drop into ChatGPT, Jasper, or another AI writer as a starting point for blog posts, ad copy, and more.
- **One-click prompt access:** Trigger prompts directly from the browser toolbar while you work in your AI writing tool, so you never break your writing flow to hunt for ideas.
- **Simple to complex prompts:** Prompts range from short simple questions to richer multi-part scenarios, making the extension useful for both quick tasks and deeper content briefs.
- **No setup required:** Install the extension from the Chrome Web Store and start using prompts immediately, with no account setup, API key, or configuration required.
- **Built for content workflows:** Designed for writers, marketers, and content creators who want more consistent output from their existing AI writing software.

**Strengths:** Completely free to install and use; Removes blank-page friction with a ready-made prompt library; Works alongside the AI writers you already use, including ChatGPT and Jasper; The prompt library spans simple questions through more complex scenarios

**Limitations:** Last updated in February 2023, so its prompt library has not kept pace with newer AI models; Very small user base and only a handful of store ratings; No paid features means no support guarantee or roadmap commitment; Prompt sets are static, with no evaluation or A/B testing tools
