lifesaver for long prompts
Finally I can type multi-line ChatGPT questions without accidentally firing half-baked thoughts into the chat box.
ctrl+enter muscle memory activated
Stops the rage of sending a broken prompt just because my finger slipped.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Pressing Enter inside a supported AI chat box inserts a line break instead of firing the message off to the model.
Deliberate submission stays available through the modifier-key shortcut, so nothing about your normal workflow is lost.
Works on ChatGPT, Google Gemini, Claude and Perplexity AI, with the supported-service list refreshed as new chat UIs launch.
Configure once and the behaviour follows you between tabs and signed-in Chrome profiles.
The developer declares that no user data is collected, sold or transferred; the extension is tiny (~99 KB) and runs locally.
Block Enter solves a small but genuinely annoying problem: AI chat boxes send your message the moment you tap Enter, so anyone who types multi-line prompts or composes thoughts slowly ends up posting unfinished messages. 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.
Write multi-paragraph prompts with headings and bullet lists without accidentally submitting halfway through.
Compose and re-read text at your own pace, then send with Ctrl+Enter only when the wording is right.
Stop the Enter used to confirm an IME conversion from doubling as a send action in chat inputs.
Keep the same Enter-to-newline behaviour whether you are in ChatGPT, Gemini, Claude or Perplexity.
