About ChatGPT Pre-Send Filter
This Chrome extension automatically replaces specified words and phrases in the ChatGPT input field before your message is sent.
You can register words or phrases that you do not want to send to ChatGPT as-is—such as company names, personal names, and project names—in a replacement dictionary.
## Key Features
- Store “target phrase -> replacement phrase” rules locally on your device
- Automatically replace registered words and phrases
- Display an on-screen notification showing the number of replacements made
- Turn the entire filter on or off
- Enable or disable individual rules
- No replacement history is stored
## Examples
Smith -> S
John -> J
Blue Sky LLC -> Company A
<Product Name> -> Product A
Dictionary entries and settings are stored locally on your device using Chrome’s local storage. They are not sent to the developer’s servers or any third party.
## Important Notes
- Text contained in attachments, such as PDFs, images, and documents, is not covered by this extension.
- The original words or phrases entered in the input field may briefly appear on the screen before they are replaced.
- The extension may stop working correctly if ChatGPT’s interface changes.
- Always review the replacement results before sending your message. This extension does not guarantee that every word or phrase will be replaced correctly.
- To the extent permitted by law, the developer is not liable for any damages arising from the use of this extension or the content submitted through it.
