## 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

## Review Express

Review Express is a Chrome extension built around one of the most repetitive tasks in research: getting through a long paper fast enough to decide whether it matters. Instead of a general-purpose summariser, it ships with pre-engineered prompts aimed specifically at scientific papers, and lets you choose a summary mode that matches why you are reading - a broad overview, the key findings, or something in between.

The published version works on highlighted text. You select a passage on a journal site or any web page, trigger the extension, and get a summary in your chosen mode. You can also ask direct questions about the selection, which is handy when you need to check whether a paper actually supports a specific claim before citing it. The developer notes that the extension consults the surrounding article text as well as your selection, so summaries are more contextual than the highlight alone would suggest.

Review Express is a small, early-stage project - the public version is 0.1.x and the developer describes more features as forthcoming. It is currently English-only in the interface, and it is an independent tool rather than something published by a journal, university, or AI vendor. For a research workflow where you read many abstracts and papers in a day, that narrow focus on scientific summarization is the main reason to try it.

**Pricing & Plans:** Freemium. The extension is free to add from the Chrome Web Store, and the developer also operates a web app at review-express-v1.vercel.app that offers a download and a sign-in, suggesting account-based paid or expanded usage. No specific plan prices or free-tier limits were published on the pages checked, so exact quotas should be confirmed in the app itself.

- **Prompts built for scientific papers:** A pre-engineered prompt library tuned for journal articles, so summaries focus on the parts researchers actually need rather than generic gist.
- **Multiple summary modes:** Pick from different summary modes depending on whether you want an overview, the key findings, or a specific angle on the passage.
- **Ask questions about the selected text:** Go beyond summarizing by asking targeted questions about the text you have selected, useful for checking whether a paper supports a claim.
- **Journal articles and general web pages:** Works on journal sites as well as ordinary web pages, so long reports, documentation, and news articles are fair game.
- **In-browser workflow:** Runs inside Chrome on the page you are already reading, with no separate app or dashboard to switch to.

**Strengths:** Prompts are purpose-built for scientific papers instead of generic summarization; Several summary modes let you match the output to your reading goal; Question answering on selected text helps verify claims before citing; Works on journal sites and ordinary web pages alike

**Limitations:** Currently only summarises text you highlight, not entire documents in one pass; English-only interface; Early-stage release with a small user base and further features still promised
