onlyreadai/onlyread is a Chrome extension that blocks write requests from artificial intelligence agents running in the browser, making them read-only. The latest release recorded in the repository is v1.0.0. The provided materials do not say what changed in this version. Therefore, no specific change can be asserted beyond the release number.
This extension aims to block send, post, edit, and delete requests before they leave the browser. Instead of changing how the model behaves, it judges requests at the network layer beneath the model. It combines rules, per-site request decoders, a decision cache, and an AI judge, and rejects a request when it has no confidence in the decision or cannot reach the judge. In other words, from the published description alone, it cannot be said to block every write path on every site; the actual scope of coverage depends on the supported sites and the request decoders.
The repository is written in TypeScript and is licensed under AGPL-3.0. It also includes a structure description, a personal data handling document, and documentation covering supported sites and limitations. The research record lists 13 stars and a momentum score of 5.6, but no novelty, technical, or quality scores are given. Since the documentation sets out the boundaries and supported scope separately, it is more accurate to view this extension as one approach to restricting writes by browser agents.
