## chatlyn AI

chatlyn AI is published by chatlyn GmbH as the official Chrome companion for chatlyn.com, a customer-service chatbot and messenger-inbox platform. The extension puts the knowledge you have already stored in chatlyn to work directly in the browser: you highlight text on any page, and it produces an answer grounded in the selected text and sends that answer to your clipboard. That means an agent can summarize a guest inquiry, draft a reply to a review, or turn a long paragraph into a short response without switching applications.

In the extension settings you can register numerous chatlyn.ai assistants and switch between them at any time, which lets one browser profile serve several workflows — for example a hospitality team handling guest messages and a support team handling product questions. Because the answers are derived from text you explicitly select, the extension is a focused writing aid rather than an autonomous agent.

The extension is free to install from the Chrome Web Store and is developed by chatlyn GmbH in Vienna, Austria. It is a companion tool, so it assumes you already use the chatlyn.com platform; on its own it will not act as a standalone chatbot. The listing notes that it handles authentication information, does not sell data to third parties, and is not used for credit or lending decisions. Interface languages are German and English.

**Pricing & Plans:** Free to install. The extension itself is free; any subscription costs come from the chatlyn.com platform it accompanies.

- **Answer generation from selected text:** Highlight text on any web page and the extension drafts an answer based on that selection, so you can respond without leaving the site you are on.
- **Automatic clipboard hand-off:** Generated answers are copied to your clipboard automatically, ready to paste into your chat, email or review-reply tool.
- **Multiple assistants, switchable:** Register multiple chatlyn.ai assistants and switch between them whenever the task changes — reviews, guest inquiries, or internal Q&A.
- **Summarize and reply in place:** Handles reviews, guest inquiries and similar inbound text directly in the browser, removing the need to jump between tabs and apps.
- **Companion to chatlyn.com:** Built and published by chatlyn GmbH as the official companion to the chatlyn.com customer-service chatbot.

**Strengths:** Turns selected text into a usable answer in a single action; Clipboard output means it drops into any reply tool you already use; Multiple assistants can be configured and swapped on the fly; Runs inside the browser, so no tab switching during support work

**Limitations:** Only useful if you already use the chatlyn.com platform — it is a companion app, not a standalone chatbot; Requires being signed in to a chatlyn account, so setup is gated by that product; Translations/interface limited to German and English; Small user base means fewer community tips and shared workflows

## 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
