Delivery work is held together by decisions made in many places: a steering call, a corridor conversation, a thread, a planning session. Individually each is small. Together they are the project. When they live only in scattered memories and half-finished notes, the person running delivery becomes the single point of failure for "what did we agree".
Overshow takes that load off you. It runs on your own machine, captures your meetings and your screen, indexes your project documents, and lets you ask a direct question to recover a decision, returning a grounded answer with when it was made, in which meeting, and the reasoning, quoted from the source. Decisions and actions are also held in a commitments record you can look up directly.
This is about eliminating your personal context loss, not measuring organisation-wide metrics. Capture, indexing and search run locally, with your data encrypted at rest, so commercially sensitive project and client information stays on your own machine by default.
Overshow does not run the project for you. It makes sure the context the project depends on is always within reach, so re-explaining and re-deciding stop eating your week.
