gtools is a suite of independent, single-purpose tools that use Sign in with Google to read — and in a couple of cases edit — one specific part of your Google Workspace data each: GTD26 and Tasks manage your Google Tasks; Omnisearch searches across your Drive, Calendar, Gmail and Contacts; Calendar View reads your Calendar; Sheet Card reads and edits rows in a Google Sheet you open; Keep reads your Google Keep notes. No tool requests more than the one Google service it needs, and everything runs entirely in your browser — there is no backend server, so your data is never sent anywhere except directly between your browser and Google's own APIs.
