Use Case Recommendations
Best for: Agnost AI
Agnost AI is product analytics for teams building conversational agents, built around a specific gap: your evals pass and production still fails. It continuously analyzes real production conversations to find where users get stuck, get frustrated, or fail to convert, clusters those into patterns, ranks them by impact, and turns the highest-impact ones into fixes your team reviews rather than a list of anomalies someone has to triage. The distinction from a standard observability tool is that Agnost is reading the conversation as a user experience, not the trace as a system event — the failures it surfaces are the ones where nothing errored and the agent still lost the user. A second output falls out of the same analysis: unmet demand. One customer describes discovering 1,247 feature requests sitting inside chats they had already had, for features they didn't have and didn't know people wanted. The company also reports autonomous pull requests, with 16 of 18 merged at one customer, so the loop runs from production signal through to proposed code change. Public references are unusually concrete for an early company — a Google engineer describing observability integrated into MCP Toolbox for Databases, a member of technical staff at Exa on analytics and error-rate tracking, and a GTM lead at Corgi Insure reporting that voice BDRs booked more meetings once Agnost surfaced which conversation patterns actually converted.
Ideal use cases:
- •Teams or individuals who need continuous analysis of production conversations for stuck, frustrated, and non-converting users
- •Teams or individuals who need failure patterns ranked by impact instead of raw anomaly lists
- •Teams or individuals who need reviewed fixes and autonomous pull requests generated from production signal
- •Teams or individuals who need feature-request mining from conversations users already had
- •Anyone focused on agent analytics workflows
- •Anyone focused on conversation analysis workflows
Best for: PromptVault
PromptVault takes prompts out of your codebase so that changing one stops being a deploy. Prompts live in a hosted vault, your application fetches the current version at request time, and an edit is live in production in under a second — no pull request, no CI wait, no production hotfix. It is deliberately not a gateway: PromptVault stores prompt text and metadata while your own code keeps calling your own LLM client, so it works with OpenAI, Claude, Gemini, Llama, Mistral, DeepSeek, Perplexity, Hugging Face, Ollama or a private gateway without introducing a proxy hop or vendor lock-in. Around that sit the operational features a team discovers it needs on the second bad prompt: full version history with one-click diff and revert, a staging-to-live promotion flow that keeps the same prompt id across environments so nothing drifts from copy-paste, a signed webhook on every save so a trace can be tied back to the exact prompt version that produced it, an activity feed recording who changed what and when, and ownership gates so a PM or support lead can edit tone directly while a reviewer controls what reaches live. An AI Evaluator runs a daily structural review and queues suspected regressions rather than waiting for the on-call alert.
Ideal use cases:
- •Teams or individuals who need live prompt edits without redeploy
- •Teams or individuals who need version history with diff and one-click revert
- •Teams or individuals who need staging → live promotion on one prompt id
- •Teams or individuals who need signed webhook on every save
- •Anyone focused on prompts workflows
- •Anyone focused on llm workflows
