Unified observability, security and incident response for cloud-scale engineering teams
Agents, cloud integrations and OpenTelemetry collectors feed one platform where metrics, distributed traces, profiles and logs can be pivoted between without context switching.
Bits AI, an agent builder and LLM/AI-agent observability help teams triage alerts, explain anomalies and monitor model latency, token spend and agent traces.
Cloud SIEM, cloud security posture management, vulnerability management, workload protection and code scanning correlate threat signals with the telemetry you already collect.
Real user monitoring, session replay, product analytics, synthetic and mobile testing sit alongside CI visibility, test optimization, feature flags and DORA metrics.

A free, AI-powered academic search engine for 240M+ papers across every scientific field
Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.

Synthesizes direct evidence-based answers from scientific papers, but has a less comprehensive raw database than Semantic Scholar.
#2
Offers an immersive AI reading and PDF analysis workspace, but is less focused on pure bibliographic search.
#3Excels at automated systematic review data extraction and evidence synthesis, but indexes a narrower slice of literature.
SpecialistProvides advanced Smart Citations showing how papers support or dispute each other, but has a smaller overall index.

SpecialistFeatures excellent visual citation collections and literature tracking recommendations, but lacks inline paper summarization features.
SpecialistOffers superior visual graph mapping of academic paper connections, but lacks traditional keyword search and full-text reading tools.
AI-native workspace for literature reviews and auditable systematic reviews

SpecialistSpecializes in tracing and debugging production LLM applications, but does not provide general cloud infrastructure metrics or log management.


SpecialistProvides advanced AI-driven threat detection for cloud networks, but focuses purely on security rather than general application performance monitoring.
