Search Fragments
Resolve half-remembered queries without guessing. A confident answer, a ranked shortlist, or an honest no. For when you half-remember something and can't place it. Half-remembered, cross-source queries usually take a dozen tabs and five rephrasings; Search Fragments collapses that into one call. Not for well-known facts, where normal search is faster.
Tools: resolve_fragment, verify_claim, submit_resolution_feedback
Free. No signup required.
Available in Claude, Cursor, Raycast and GitHub, or add the URL below to any MCP-compatible agent.

Why this exists
AI agents tend to become confidently wrong on fragmented queries: partial memories, indirect relationships, missing names. There's real signal in the fragment — enough for a model to recognize the pattern — but not enough to verify an answer from memory alone. The result is fluent, specific, and wrong.
Search Fragments is built to decline rather than guess. Every query resolves to one of three honest shapes:
- Resolved — a named answer, with confidence backed by evidence found.
- Weighted Partial — a ranked shortlist of candidates to decide by eye.
- No Resolution — an explicit "not resolvable from these clues," with no confidence claimed.
In a test against a baseline agent on 50 hard, under-documented fragments, the baseline fabricated three specific wrong answers with no hedge — Search Fragments declined honestly on all three. Full write-up: searchfragments.com/agent-hallucinations.
