The extension intercepts that keypress on supported sites and turns Enter into an ordinary newline, while you press Ctrl+Enter or Cmd+Enter to deliberately submit. It is not limited to one service. The developer maintains an active list that covers ChatGPT (chatgpt.com), Google Gemini, Claude and Perplexity AI, and the list is updated as new platforms appear. Settings are synchronised across tabs and browsers, so a single configuration follows you between open windows and signed-in Chrome profiles rather than having to be repeated on every site. The extension is published on the Chrome Web Store by an independent developer, is free to install, requests no data collection, and is a good fit for power users, writers and anyone who drafts long prompts with line breaks or bullet lists. **Pricing & Plans:** Free. The extension has no paid tier, subscription or in-app purchase; installing it from the Chrome Web Store is the only step. - **Enter becomes a newline:** Pressing Enter inside a supported AI chat box inserts a line break instead of firing the message off to the model. - **Ctrl/Cmd+Enter to send:** Deliberate submission stays available through the modifier-key shortcut, so nothing about your normal workflow is lost. - **Multi-platform coverage:** Works on ChatGPT, Google Gemini, Claude and Perplexity AI, with the supported-service list refreshed as new chat UIs launch. - **Settings sync across tabs and browsers:** Configure once and the behaviour follows you between tabs and signed-in Chrome profiles. - **No data collection:** The developer declares that no user data is collected, sold or transferred; the extension is tiny (~99 KB) and runs locally. **Strengths:** Free with no account, no ads and no data collection declared; Covers four major AI chat platforms rather than a single one; Settings stay in sync across tabs and browsers; Very small install size with negligible performance impact **Limitations:** Only works on the specific AI sites the developer has added to its list; Last update was September 2024, so very new chat UIs may not be covered yet; Small user base and a modest rating, so long-term maintenance is not guaranteed [Profile (Markdown)](https://openaitools.app/tool/block-enter.md) ## PromptBox PromptBox is designed for people who write a lot of prompts and reuse them constantly. It replaces scattered notes and browser bookmarks with a single, searchable library of prompts and snippets you can organize into folders. Each prompt can include variables, so when you trigger it a small field appears and you fill in the specifics before the text is inserted — useful for outreach emails, customer service replies, code snippets and terminal commands alike. Insertion is the core of the experience: you type a short trigger and PromptBox expands it into the full content, directly in Gmail, ChatGPT, your docs, your code editor or any website that accepts text. This turns PromptBox into a practical cross-application text expander rather than just a prompt repository. PromptBox has been available through early-access marketplaces as well as its own site, and reviewers highlight its folder organization, working custom variables and responsive support. It runs as an extension-style tool that stays out of the way until you need it. **Pricing & Plans:** PromptBox offers a free trial and paid plans; lifetime deals have historically been available through marketplaces such as AppSumo. Check the official site for current tiers and pricing. - **Prompt & snippet library:** Store prompts, replies, code snippets and templates in folders so your best content is always one search away instead of buried in notes. - **Custom variables:** Add variables to any prompt and fill them in through a small field when you use it, so one template adapts to many situations. - **Shortcut insertion anywhere:** Type a trigger and PromptBox expands it into full text directly inside Gmail, ChatGPT, docs, editors or any site with a text field. - **Cross-tool reusability:** Keep one library that works across your AI tools and everyday apps, ending duplicate copying and pasting between them. - **Organization & search:** Folder-based organization and quick search make a large collection of prompts manageable and easy to maintain. **Strengths:** Turns scattered prompts and snippets into one organized, searchable library; Variables let a single template serve many situations; Works across apps and sites, not tied to one AI provider; Custom variables and folder structure are repeatedly praised by users **Limitations:** The main site is JavaScript-heavy, so some tools and previews need a browser to load fully; Value depends on building and maintaining your own prompt library; Feature parity across every supported platform and browser may vary [Profile (Markdown)](https://openaitools.app/tool/promptbox.md) ## Frequently Asked Questions ### How do Block Enter and PromptBox compare in monthly traffic?
