The recorded URL now redirects offsite — often an acquisition, rebrand, or wind-down; the destination is recorded in the telemetry below. Pulse has been flat over the last 30 days.

generated from the observed metrics above · no external narrativeLUIS.ai's listed URL redirected off its original domain (to https://learn.microsoft.com/en-us/previous-versions/azure/ai-services/luis/?tabs=rest-api) when we last probed it on Aug 26, 2026 — we mark it redirected, not dead. Its Pulse Index is 19.2 of 100, built from 2 of 4 observed signal families. Observed footprint: 9 functional tags. It has no curated competitive-alternative edges yet, so the comparable set below is functional tag-similarity — read it with the confidence flags.

Confidence reflects source and category coherence: curated = an editorially linked alternative; similar = strong functional tag-overlap in the same category; tag-overlap = shared tags only and may be noisy. Overlap is the shared functional-tag ratio (Jaccard) for tag-matched rows. Pulse is the observed-activity index real and 30d Δ its signed month change; a dash means insufficient observed history, never zero.
