The data, evaluations and systems behind AI that has to be right.
Human-sourced and expert-annotated training data, including specialist contributors with advanced degrees, at the quality bar frontier labs require.
Public leaderboards plus private benchmarks that test model capability and safety for the most ambitious AI developers.
Platform and services teams that pick the right use case, build the system and take ownership of the outcome.
Agentic systems designed around measurable business outcomes across private equity portfolios, energy and healthcare operations.

The collaborative whiteboard built for product builders
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.
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.
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.

#2
Focuses heavily on enterprise data labeling and training data curation, similar to Scale's core annotation business.
Free / Open-sourceCombines mind mapping and project workflows with AI agents, but less focused on pure visual diagramming and wireframes.
Robust collaborative whiteboard with strong AI diagramming tools, but less polished UI wireframing capabilities than Whimsical.

Provides enterprise multimodal annotation and data management tools, but with less emphasis on managed labeling workforces.

SpecialistTrack, evaluate, and ship AI models and agents in one connected environment.


SpecialistFocuses on post-deployment LLM observability and evaluation rather than training data generation or annotation.
Specializes in data infrastructure and annotation specifically tailored for computer vision and physical AI workloads.

Dedicated diagramming platform with strong AI chart generation, but less focus on freeform collaborative brainstorming whiteboards.
SpecialistInstantly turns natural language prompts into mind maps and flowcharts, but offers less freeform canvas drawing flexibility.
Combines whiteboarding and documentation with AI generation, but lacks Whimsical's specialized wireframe shape library.
