Overlay

Turn any Google Doc, Sheet, or Slides deck you already have into a reusable template. Highlight text (or a cell), turn it into a variable, and edit it once — every occurrence updates instantly, in the real file. No find-and-replace, no rewriting your document, no new tool to learn. HOW IT WORKS Select text or a cell and copy it (Cmd/Ctrl+C) Click "Create Variable" in the sidebar Edit the value — every occurrence updates live WHAT'S INCLUDED • Google Docs, Sheets, and Slides • Unlimited variables and documents — free, no account • Sheets: bind to one cell, one sheet, or the whole spreadsheet • Slides: bind to one slide or the whole deck, with jump-to-slide navigation • Multi-tab Docs fully supported • Built-in undo for edits and deletions • PDF/Word export in Docs Overlay reads only the file you connect it to. Your content is never sent to our servers. Questions or ideas: overlaylab.co/support --------------------------- New: Google Slides support. Turn slide text into a variable — update once, every occurrence in your deck updates live. Bind to one slide or the whole deck, with a sidebar that jumps you straight to each occurrence.
