Show HN: Deepmark – Search your bookmarks by what's inside them, not the title

Deepmark, a bookmark search tool, launched publicly on August 13, 2026, per a Show HN post by author shafkathullah. The product is accessible at usedeepmark.com and positions itself around indexing the full content of bookmarked pages rather than relying on titles or URLs alone.

The core proposition, as described in the HN listing, is that users can retrieve saved links by searching for concepts, phrases, or details that appear within the pages themselves — not just the labels they assigned at save time. This targets a common frustration with browser-native bookmarking, where retrieval depends on the user remembering what they titled a link or which folder they filed it under.

The Show HN post provides no information about the founding team beyond the submitting username, no disclosed funding, and no detail on pricing or whether a free tier is available. The post received 2 points and no comments at the time of publication.

Semantic or full-text bookmark search is a narrow but recurring space. Tools like Raindrop.io, Pocket, and browser extensions such as Memex have offered various degrees of content-aware search for saved links. Deepmark's framing — "what's inside them, not the title" — suggests a semantic or crawl-and-index approach, though the technical implementation is not described in the available sources.

No roadmap, hiring plans, or expansion details were included in the HN post. The launch's traction and whether the tool supports major browsers or requires a dedicated import step remain unconfirmed from the available sources.
