The AI that builds better AIs

Tropir is the first AI that builds better AIs. We don’t just trace where your pipeline broke—we fix it. Tropir analyzes the flow of logic across prompts, tools, and retrievals to pinpoint root causes, suggests targeted changes, reruns the pipeline with those fixes, and runs evals to check if things actually improved. If not, it keeps iterating until they do. You build the flow. We make it unbreakable. We're already used by teams building advanced agents, copilots, and RAG pipelines. As LLM-based systems grow, we believe Tropir will become essential infrastructure for every serious AI team.

Modern AI pipelines fail constantly—hallucinations, bad retrievals, broken tool calls.

Tropir fixes that.

It traces exactly where things went wrong, suggests a targeted fix, reruns the pipeline, and tells you if the fix worked. All automatically.

🔁 Trace → Fix → Rerun → Evaluate → Repeat

Most observability tools stop at logs. Tropir doesn’t just show you what broke—it tells you why, applies a fix, reruns the whole pipeline, and checks if the problem’s actually solved.

You can say: “Figure out why the @last_log wasn’t grounded in retrieved context. Use @faithfulness_eval.” Or just: “This output sucks. Use the full eval set to fix it.”

Tropir handles the rest.

🧠 Why Tropir is Different

  • Traceback Engine — Finds the root cause across prompts, retrievals, tools, and context.
  • Fix + Rerun — Smart patches injected on the fly. No code rewrites.
  • Built-in Evals — Relevance, grounding, structure—all tested automatically. Add your own evals if you like!
  • Conversational Interface — It’s like interrogating your agent after runtime.
  • Plug & Play — Two lines of code to setup Tropir and you’re done.
