## 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

## SAiY

For organisations, it leans on security: SAiY describes itself as the AI keyboard built around enterprise data policy, with customizable controls and Enterprise features such as centralized deployment and billing, a dedicated account manager and volume discounts. It is published by Adi Holding LLC.
