AI diagrams and technical design docs built from your code and systems
Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.

#1
Large consumer panel for market research surveys, but lacks Prolific's specialized focus on academic studies and AI tuning.

SpecialistAutomatically embeds visual diagrams directly inside text documents, though it lacks Eraser's specialized cloud architecture focus.
#3
SpecialistThe environments frontier AI trains on, and the agents that do the recurring work

Enterprise-grade data annotation and AI alignment workforce, but less self-serve for academic study recruitment and casual surveys.

SpecialistAI data infrastructure for building production-grade models
Provides extensive drag-and-drop shapes and templates for general diagrams, but weaker automated code-to-diagram capabilities than Eraser.

SpecialistSpecializes in video-based consumer interviews and AI qualitative analysis, but less focused on quantitative academic survey panels.


SpecialistSources verified B2B professionals and healthcare experts for specialized research, but lacks broad general-population academic panels.

Combines team whiteboarding, documentation, and diagramming in one platform, but less tailored for automated codebase architecture.

Free / Open-sourceOpen-source data labeling and evaluation platform for AI workflows, but requires bringing your own annotation workforce.
