ChatGPT Enter Key Control (by marusin)

Prevent accidental sends when you meant to insert a line break in ChatGPT.

Press Enter for a new line. Send when you're ready. ChatGPT Enter Key Control stops Enter from sending your message while you're still writing. Use Enter for new lines, then send with Shift+Enter, Ctrl+Enter, Cmd+Enter, or the shortcut you choose. Finish your thought before you send. ✨ Latest update (September 29, 2026) Updated for the ChatGPT web input environment as of September 29, 2026. Improved composer detection when multiple input fields exist within the page, improving compatibility and stability for Enter-to-new-line behavior and configured send shortcuts. ✨ Featured feature Includes a fix for an issue that can cause IME input to become scrambled after pasting multiple lines of text. ■ How to use 1. Install the extension 2. If ChatGPT is already open, reload the page once 3. Use Enter for new lines and Shift+Enter to send ※⚠️ IMPORTANT: If the extension does not work immediately after installation, reload the ChatGPT page once. The extension is enabled by default, so you can start using it right away. If you prefer, open the extension from your browser toolbar to choose another send shortcut or turn Enter-key control on or off. ■ Main features ・Enter inserts a new line instead of sending immediately ・Send only when you're ready ・Choose your preferred send shortcut ・Supports shortcuts such as Shift+Enter, Ctrl+Enter, Cmd+Enter, and Shift+Cmd+Enter ・Designed to work smoothly with IME input ・Helps reduce IME input issues that can occur after pasting multiple lines of text ・Helps prevent unintended duplicate sends caused by holding down a key ・Settings can be changed anytime from the extension popup ■ IME input after pasting multiple lines In some environments, IME input may become scrambled after pasting multiple lines of text. The extension adjusts the handling of supported simple multiline text pastes so that you can continue typing with IME more smoothly afterward. It does not interfere with unsupported paste types such as HTML, rich text, images, files, or URLs, allowing the original paste behavior to take priority. ■ Supported service The extension supports the official ChatGPT web version. Both the current web version and the legacy domain are supported. ■ Not supported The extension is designed for the standard chat message composer. It does not apply to input fields inside dialogs or fields that cannot be reliably identified as a supported composer. It also does not apply to web services other than ChatGPT. ■ Privacy and security ・No input content is collected ・No conversation content is collected ・No input content is stored ・No input or conversation content is sent to external servers ・Only the permissions required for supported features are used ・The source code is publicly available on GitHub ■ About site permissions This extension uses site access permissions to control Enter-key behavior in supported chat input fields. The extension does not collect, store, or transmit your input or conversation content. Site access permissions are used only to control Enter-key behavior in supported input fields. ■ Release notes Version 1.3.2 ・Updated for the ChatGPT web input environment as of September 29, 2026 ・Improved composer detection when multiple input fields exist within the page ・Improved compatibility and stability of Enter-key control Version 1.3.1 ・Added compatibility with the new web message composer as of September 27, 2026 ・Improved compatibility so Enter for new lines and configured send shortcuts work correctly with the new composer ・Extended the multiline-paste IME fix to work with the new composer Version 1.3.0 ・Improved an issue where IME input could become scrambled after pasting multiple lines of text ・Improved multiline plain-text paste handling for better compatibility with IME input Version 1.2.0 ・Added Cmd+Enter / Shift+Cmd+Enter send shortcuts on Mac ・Improved compatibility with Japanese, Chinese, Korean, and other IME input so Enter-key control is less likely to interfere with text conversion or confirmation ・Fixed an issue that could insert an extra line break in certain situations Version 1.1.6 ・Added Spanish, Brazilian Portuguese, and Traditional Chinese UI support ・Fixed an issue where the language selector could be clipped in some languages If ChatGPT Enter Key Control helps you finish what you're writing without sending too early, a rating or review on the store would be greatly appreciated.
