A persistent intelligence layer

Continuous intelligence
for software systems

AI is accelerating software development, but it also increases system risk. Overtones continuously understands your code, architecture, and runtime behaviour — helping engineers and AI tools make safer, more informed decisions.

Modern software systems evolve too quickly for teams to fully understand their impact. We build a persistent intelligence layer over your repositories, infrastructure, and operational data, enabling automated insights, safer AI-assisted development, and faster incident diagnosis.

You're on the list — we'll be in touch.

Early access. No spam.

Three capabilities, one intelligence layer

Continuously understand your system, guard it against AI-driven risk, and connect development decisions to real-world outcomes.

01
Understand Your Software System
Continuous intelligence across code, architecture, and documentation.

We build a structured understanding of your repository, extracting entities, relationships, and knowledge so both engineers and AI tools can reason about the system.

  • Code entities & dependency graphs
  • Semantic embeddings & knowledge
  • Architectural structure
  • AI-queryable system model
  • Change impact analysis
02
Guardrails for AI-Driven Development
Prevent regressions and architectural drift before changes merge.

Automatically analyse pull requests using repository intelligence to identify risks, diagnose problems, and provide actionable feedback — before they reach production.

  • PR risk analysis
  • Architectural drift detection
  • Dependency impact analysis
  • Documentation validation
  • Human-in-the-loop review

03
Diagnose Systems Faster
Connect code, infrastructure, and runtime behaviour.

Trace incidents back to the changes and architectural factors that caused them, enabling faster diagnosis and more reliable systems.

  • Change-to-incident tracing
  • Runtime behaviour correlation
  • Automated root cause analysis
  • Operational context for engineers
  • Continuous feedback into dev

Connected to everything that matters

Overtones ingests signals from across your stack — then continuously builds and maintains the intelligence layer on top of them.

01
Connect your repository

Overtones indexes your code, commit history, and documentation using tree-sitter AST analysis and semantic embeddings.

02
Build system intelligence

Entities, relationships, and architectural structure are maintained as a persistent, always-current knowledge model.

03
Connect operational context

Enrich the model with docs, infrastructure, and runtime signals for full lifecycle intelligence.

Where intelligence gets applied

The same system model powers insights across the full engineering lifecycle.

PR Review
  • Automatic risk scoring on every pull request
  • Regression & drift detection against the live model
  • Dependency impact traced through the graph
  • Actionable feedback for engineers and AI agents
Incident Diagnosis
  • Runtime signals correlated to code changes
  • Root cause traced back through deployment & PR history
  • Architectural context surfaced alongside the incident
  • Faster resolution with structured, traceable evidence
Architecture Insights
  • Query system structure as it actually exists today
  • Dependency graphs & module boundaries always current
  • Drift from intended architecture surfaced continuously
  • Onboard engineers with a live map of the codebase
AI Context
  • Structured knowledge fed directly to AI coding tools
  • Entities, relationships & intent — not raw files
  • Safer AI-generated code through system-level awareness
  • Compatible with any MCP-capable AI agent
