Open infrastructure for trustworthy AI in safety science.
in4r helps toxicology, chemical-safety, biotech/R&D, and regulatory evidence teams turn existing tools and data sources into private, auditable AI workflows. Every source, tool call, assumption, and human review gate can be captured.
Scientific track record, public infrastructure, and a practical bounded-pilot model.
Creator/maintainer of public open-source tooling, including ToxMCP modules and O-QT-related workflows
Open infrastructure across ToxMCP, O-QT, QSAR, PBPK, exposure, ADMET, and AOP workflows
Opening pilot and design-partner conversations for review-heavy safety-science workflows
Consulting and infrastructure for scientific teams adopting AI carefully.
Start with one workflow, one accountable team, and one useful artifact. Then decide what should become reusable infrastructure.
Turn one real case study into an inspectable AI workflow.
Bring a workflow where speed matters, but traceability, privacy, and expert review cannot be optional.
Example: connect OECD QSAR Toolbox outputs, profiler alerts, analogue rationale, literature context, and expert review into one evidence bundle with provenance and audit logs.

in4r is not starting from a blank slide deck. The public ToxMCP suite shows the practical direction: modular MCP servers for safety-science tools, evidence sources, and reviewable workflows.

PUBLIC REPOSA public module map for chemical safety, toxicology, QSAR, exposure, PBPK, ADMET, and mechanistic reasoning workflows.
Paid pilots and consulting help turn this infrastructure into stable, documented, reusable open-source tools.
O-QT assistantStart with one case-study pilot or advisory retainer.
Bring one safety-science or research case study. We will define the pilot boundary, consulting scope, evidence sources, review gates, and deployment path before scaling anything. We are opening pilot and design-partner conversations for teams operationalizing AI in review-heavy scientific workflows.
