## ChatGPT Rewriter

ChatGPT Rewriter is a browser extension for people who write in the browser and want AI help without leaving the page. When you highlight editable text, the extension shows a small menu with two choices: "Rewrite using ChatGPT" to improve or rephrase the selected passage, and "Ask ChatGPT" to pose a question whose answer replaces the selection. A loading indicator appears in the upper right so you know processing is underway.

Setup is straightforward. The extension requires a ChatGPT account, and it walks you through generating and configuring the OpenAI API key it uses to make requests. Once the key is stored, the rewrite and ask actions work from the selection menu rather than a separate chat window, which keeps the workflow focused on the document or field you are editing.

The extension is published by an individual developer, is free to install, and was last updated in 2023. It carries a featured badge on the Chrome Web Store and has a few hundred users. Because it relies on your own API key, running costs depend on your OpenAI usage rather than on the extension itself, and it is a lightweight assistive tool rather than a full writing suite.

**Pricing & Plans:** Free to install; usage depends on your own OpenAI API key and any charges on your OpenAI account.

- **In-place rewriting:** Select text in any editable field and have ChatGPT rewrite it without leaving the page.
- **Ask-and-replace:** Pose a question about the selected text and drop the answer straight into your document.
- **Selection menu access:** The rewrite and ask options appear right where you highlight text, so there is no extra panel to manage.
- **Bring-your-own API key:** You connect your own OpenAI key, keeping control of the account and its limits.
- **Progress indicator:** A small corner indicator shows when your text is being processed.

**Strengths:** Works inline on any editable text field; Two clear actions: rewrite and ask; No separate ChatGPT window needed while writing; Free extension with your own API key

**Limitations:** Requires you to create and configure an OpenAI API key; Low user rating in reviews at the time of listing; Not updated since 2023, and API changes could affect it

## 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
