Calendar Event Creator

Create Google Calendar events from selected text or a screenshot using OpenAI

Calendar Event Creator turns anything on a webpage into a Google Calendar event. Select text, or draw a box over a poster, invite, or screenshot, and AI extracts the details — title, time, location, description — ready to confirm and add. What's new in v1.3.0 - New: create events from a screenshot. Click "Capture screenshot" in the popup, or right-click and choose "Add screenshot to Google Calendar", then draw a box over the part of the page that holds the event - Only the box you draw is captured — it's downscaled in your browser, sent for extraction, and discarded, never stored. Press Enter or double-click for the whole visible tab; Esc cancels - A thumbnail in the confirmation window shows exactly what was read - The right-click screenshot item steps aside when you have text selected, so a selection offers the text action alone — and it can be turned off entirely in the popup - Fixed: the usage bar shows your real monthly count as soon as the popup opens, events you haven't added yet survive a failed screenshot, and you stay signed in after an extraction Key features - One-click event creation from any webpage text - Screenshot any part of a page — posters, embedded calendars, chat screenshots, PDFs — and turn it into events - Multi-event extraction — select text with several events and get them all at once - Automatic timezone detection using your browser's timezone - Works with receipts, card transactions, reservations, deliveries, and other dated records - Event titles match the language of your text (Japanese text → Japanese titles) - Preview and confirm in a draggable window; each event has its own "Add to Calendar" button - Visual usage tracker with color-coded progress bar (for signed-in users) Two ways to use it - Sign in with Google (recommended): 50 free event creations per month, no API key needed — and failed requests don't count against your limit - Bring your own OpenAI API key: unlimited client-side processing, for text and screenshots alike Perfect for creating events from emails, messages, receipts, booking confirmations, posters, or any text or image containing a date.
