## 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

## PromptPolish

PromptPolish removes the copy-paste loop from AI-assisted writing. Instead of opening a chat window, pasting a paragraph, waiting for a reply and pasting the result back, you select text directly on the page, pick or type a prompt, and the extension replaces the selection with the rewritten version. Because prompt templates are reusable, recurring tasks such as tightening a draft, changing tone, fixing grammar or translating a block of text become one-click actions.

The extension deliberately stays thin on infrastructure. You bring your own API key for the AI service you want to use, and PromptPolish only relays the request and the response. According to its Chrome Web Store disclosure, the developer does not collect or sell your data, and your credentials are stored locally and shared solely with the provider you define. That design keeps the extension free to run while giving you control over which model handles your content.

PromptPolish is a small, early-stage project — it has modest install numbers and few reviews, and its last store update was in December 2024. It is nonetheless available, installable and functional, and it suits users who want a minimal, privacy-conscious rewriting helper rather than a full writing suite.

**Pricing & Plans:** The extension itself is free to install and use. You pay only your chosen AI provider for the API calls the extension makes, since you supply your own API key.

- **In-place text rewriting:** Select text on any web page and replace it with an improved version without leaving the page or touching the clipboard.
- **Custom reusable prompts:** Define your own instructions — shorten, formalize, translate, summarize — and reuse them across pages and sessions.
- **Bring your own AI provider:** Connect the extension to services such as OpenAI using your own API key, so you control cost and model choice.
- **Privacy-minded storage:** Credentials, inputs and prompts are kept locally and sent only to the AI service you explicitly configure.
- **Simple popup workflow:** A compact interface keeps the rewrite action one or two clicks away, aimed at speed and low friction.

**Strengths:** Free extension with no subscription for the tool itself; Keeps you in the browser instead of a separate chat tab; Custom prompts make repetitive rewriting tasks fast; Credentials stored locally and shared only with your chosen provider

**Limitations:** Requires you to obtain and configure your own AI API key; Small install base and very few user reviews; Last Chrome Web Store update was December 2024, so the project moves slowly
