Introduction

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

Last updated: 24 September 2026

Overshow

Overshow is knowledge capture for consultancies. It runs on each consultant's computer, on Mac and Windows, reads the work on screen as text and keeps it in an encrypted private history. Once engagement records are set up for your consultancy, Overshow drafts a day record against the engagement the work belongs to. The consultant checks and approves the record, then chooses what to publish for colleagues who can access the engagement.

Search matches words in your captured history. On the Mac, Ask uses retrieved passages to produce answers with source references. Open those sources to check an answer against the captured text.

Everyday use

Local processing

Your private history, the local capture index, stays on your computer. Text extraction and search run locally on Mac and Windows. Ask runs on the device on a Mac, and on Windows it uses an AI provider you set up. Meeting recording requires an experimental Mac build with meeting support. Existing transcripts remain searchable when the installed build omits recording. A separate Publish action sends an approved record and its approved source excerpts to the organisation repository, and the privacy overview lists every other route, such as an AI connection you approve.

Capture

Overshow captures screen text on Mac and Windows. Experimental Mac builds with meeting support can also capture meeting audio. Screen capture is event-driven: when your active window changes, Overshow reads the on-screen text (accessibility-first, with OCR where needed) and indexes it locally. No screenshots or video are stored: only the extracted text and metadata that make your work searchable. In a build with meeting support, audio is recorded only while a meeting is active or manually started, and on-device speech-to-text turns it into searchable transcripts. With your permission, Overshow can also draw on your calendar and connected email accounts for context. Watched-folder document indexing is unavailable in this release. Visible document text can still enter screen capture in an allowed application. Together these build a searchable record of what you saw, discussed, and decided.

Grounded answers

You can search across captured screen text, meeting transcripts on the Mac and authorised mail excerpts using full-text retrieval. When you use Ask, Overshow finds and presents information drawn from your captures rather than producing generic text from a model alone.

Consultancies

Overshow is built for consultancies. Consultants use it to keep an accurate record of each engagement: what the client asked for, what was decided and what is still open. Published records give colleagues the same picture for handover, scope and dispute discussions, in Overshow or, if the consultancy uses it, Microsoft 365 Copilot.
