Project memory
One project memory,
every source.
One memory, every source
Capture pasted ChatGPT conversations, supported shared ChatGPT and Claude links, notes, URLs, email, repository documentation, and Mac Companion activity.
Decisions with evidence
Keep sources, assumptions, owners, approval status, related tasks, superseded choices, and project-health effects together.
Bounded context for AI
Discover intent, select a project, rank evidence, respect token budgets, and send only relevant context to the configured provider.
Context Engine
Relevant context, assembled before the model answers.
ReasonTrail does not indiscriminately send an entire database to a model. It builds a bounded, versioned context package for the selected provider.

Human review boundary
AI can propose. People control the record.
Important project memory is not silently accepted. Proposed changes enter review with their provenance attached.

Verified Operator actions follow one persisted lifecycle. Sensitive writes require scoped approval, and memory is updated only after verification.
Model Context Protocol
A controlled boundary between AI clients and project memory.
Cloud MCP is coming during private beta. The planned endpoint is not operational. Local stdio MCP remains available for developers and self-hosted installations.
