Introduction

What Overshow is, who it is for, and how local capture and search fit together.

Last updated: 2 April 2026

What is Overshow?

Overshow is a privacy-first tool for screen and audio capture with search built for knowledge work. It records what appears on your screen and what you say nearby, processes that material on your Mac, and stores it in a local database so you can find it quickly later.

Search combines full-text matching with semantic search, so you can ask in your own words and still surface relevant moments. Answers are grounded in what Overshow has actually captured — nothing is invented beyond your own content.

Why people use it

Privacy-first, on-device processing

Your captures stay on your machine. Processing — including transcription, text extraction, and embeddings — runs locally. That keeps sensitive work inside your environment and reduces dependence on cloud services for day-to-day recall.

Comprehensive screen and audio capture

Overshow records screen activity and microphone audio. On-device optical character recognition pulls text from the screen, and speech-to-text turns audio into searchable transcripts. Together, they build a searchable record of how work actually happened.

AI-powered search with grounded answers

You can search across OCR text, transcripts, and related signals using both keyword and meaning-based retrieval. When you use Ask, Overshow finds and presents information drawn from your captures rather than producing generic text from a model alone.

Who it is for

Overshow suits knowledge workers who need reliable recall across tools and conversations: engineers revisiting decisions, operations staff tracing incidents, support teams checking past cases, and product people reconstructing context. It is aimed at individuals and teams who value local control and auditability.
