AI governance, testing, and observability for regulated enterprises
AI test library and custom evals
Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
CI/CD regression testing
Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
Observability, tracing, and cost analytics
Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
Governance registry and lifecycle gates
Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.
Strengths & Pros
+Covers the full loop from pre-release testing to production monitoring and governance in one platform
+Strong compliance and risk-mapping capability built for regulated industries
+Generous free Basic plan makes evaluation tooling accessible to small teams

Whimsical
The collaborative whiteboard built for product builders
Prompt-to-visual AI tools
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
One infinite canvas
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Real-time multiplayer editing
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.

Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
Strengths & Pros

+Single workspace replaces separate diagramming, whiteboarding, wireframing and docs tools
+Unlimited viewers and guests are free on every plan, including Free

Limitations
–Free plan caps you at 50 board objects and 50 doc blocks per month plus export watermarks
–AI credits are limited per seat and extra credits cost more
–Advanced admin and security features are locked behind the Business tier
–Very large, asset-heavy boards can feel slower than focused single-purpose tools
–No full offline mode; the desktop app still depends on connectivity
