Search webpages by meaning or exact words. Private, offline, and entirely on your device.

SemSearch lets you search beyond keywords to find what you mean. It’s free, preserves your privacy, and uses an AI model that runs entirely on your device with no ads or account setup. For the best experience, use a powerful computer, as indexing can be slow on less capable devices. Add SemSearch to Chrome and start searching by meaning. • See exact and keyword matches first, followed by related ideas with similarity scores. • Move between highlighted sentences with the arrows. • Reuse prepared sentences across searches. Stop and continue preparation without losing progress. • Search offline with the included model. No account, tracking, or search uploads. • Search selected text from the right-click menu. • English and Turkish interface. Page preparation starts when you open semsearch. You can search immediately while it runs; the first preparation may take longer as the model loads. Semantic search requires WebGPU; keyword search remains available without it. Search covers loaded, visible page text, excluding protected Chrome pages, embedded frames, and editable fields. Related matches are suggestions and can miss your meaning. By lessontime.ai.
