Two small tools for people who work out of Gmail. Both run entirely in your browser: nothing is uploaded, nothing is stored, and neither one asks you to sign in or connect an account.
Gmail Search Operator Builder
Build a Gmail search string from a form — sender, size, age, attachments — and open it straight in Gmail.
Gmail Filter Generator
Build filter rules, download the XML, and import them all into Gmail at once.
We build Google Workspace add-ons for a living — Simple CRM for Gmail keeps contacts, notes and follow-ups in the Gmail sidebar, and Gmail to Calendar AI turns an email into a calendar event.
