The Synapse Ecosystem
Synapse makes AI aware of human states. It integrates with tools like Claude Code and VS Code, managing interruptions and matching help.

Synapse Ecosystem
A layer, not another assistant
Your team keeps the agents and models it already uses. Synapse is the layer underneath delivered primarily as an MCP server supplying what those tools can’t see on their own.
Consent-gated HSI signals — focus, fragmentation, capacity — so AI tools can time and shape their help.
A “why” graph of decisions and context, built from the tools your org already works in.
Org-scoped GitHub, Slack, and Notion connectors feed the work-signal side of the picture.
Works with the host’s agent loop and model over MCP nothing to replace.
The AI Effectiveness Index
Each case study follows one research question from hypothesis to finding, and where relevant, into what shipped. 2 active studies, more added as they progress.
Works with the host’s agent loop and model over MCP — nothing to replace.

Two views, one boundary
Private self-insight: flow, focus fragmentation, context switching, and (with consent) how work demand lines up against capacity.


Privacy-preserving team-health aggregates — how the system of work affects the team. Never individual scores, never rankings.
Synapse measures how work and human capacity interact. It measures the system, not the person and that boundary is architectural, not policy:
Read Privacy & Data
The consent gate executes on the device before serialization — an unconsented field is never created, not merely hidden.
Aggregates require a minimum cohort of 10 consented participants, enforced in the aggregation service, not the UI.
Opt-out is invisible to managers — absence is indistinguishable from cohort-floor suppression.
There is no individual-record endpoint for organizational roles, and no configuration that creates one.
No emotion inference in workplace deployments — by design and by policy.
Principles
never surveillance, never scoring.
opt-in, transparent, revocable at any time.
Physiological signals remain on-device; Synapse uses validated HSI output.
adapt systems around engineers, don’t replace them.
Why Synapse
Coding agents grasp code and builds, but not the humans. A 2,000-line refactor is reasonable but harmful under cognitive load. Interruptions cost time; refocusing takes about 23 minutes, impacting productivity.


FAQ
Synapse is live for AI-first engineering teams. It plugs into the agents you already run over MCP, measuring the system, not the person.
