Bigspin is an AI agent monitoring platform that helps teams building AI products see their invisible failures, understand why their happening, and resolve them quickly. By analyzing 100% of conversations rather than samples or flagged cases, Bigspin surfaces failure patterns, quality drops, and user pain points that standard monitoring tools miss entirely. Early-stage teams use it to catch invisible failures before they tank retention, without standing up a dedicated QA team or building eval infra from scratch. Enterprise teams use it to scale conversation analysis across millions of interactions, with the audit trail and governance leadership requires.Documentation Index

How Bigspin works
Bigspin follows a simple loop that turns AI transcripts into actionable improvements:Connect your transcripts
Import conversation data from files (CSV, JSONL, Parquet) or connect a data source like LangSmith or Braintrust to stream traces automatically. We run LLM annotations on every message, tool call, event, and trace — not keyword search and not just sampling. Consistent analysis across 100% of your transcripts.
See what's happening
Did your agent even answer the right question? Did the user encounter any friction? Was the AI factual and behaviorally consistent? What are users doing that you didn’t expect?Each finding comes with evidence, severity, and recommended action. Your roadmap becomes a function of what users actually experience.
Act on what matters
Bigspin delivers a daily briefing built for product teams: what went wrong, why it happened, what to do about it. This is not another dashboard, it’s an analyst working alongside you, investigating issues, surfacing patterns, and recommending what to ship next.Every recommendation is traceable to specific conversations, defensible to leadership, reviewable by your team, and auditable for compliance.
