Small tools that do one job.

Three extensions for Chrome. Each does a single thing well, in the browser you already have open. Nothing they read about you leaves your computer: the only request any of them can make is a licence check, and the build refuses to package if a network call appears anywhere else.

Channel Blocklist Free Hide blocked channels in YouTube search, Home and the sidebar. Optional comment hiding. Free, with a local blocklist.
Search Browser History $4.99 one-time Save and search browser history beyond 90 days. Find old pages by title, site or date in a private local archive.
Chat History Search $6.99 one-time Search the AI conversations you open across ChatGPT, Claude and Gemini. Saved locally after installation; reopen older chats to add them.

How they are built

One job each

No suites, no dashboards, no account. Install it, use it, forget it is there.

Local by construction

In each of the three, the packaging script refuses to build if fetch, XMLHttpRequest, sendBeacon, WebSocket or EventSource appears in a file that handles your data. Enforced by the build, not promised in a sentence.

Buy once

Where there is a paid feature it is a single payment and a licence key you paste in. No subscription, no login, no email address required.
