Event Dropper
User Guide

For first-time users

Just drop the event document. The event goes to your Calendar and the file goes to your Drive — in one step. You can also create a WhatsApp/SNS post from the same details.

What is Dropper?

Dropper is a web tool that reads an event document (PDF or image), creates the event in your Google Calendar, and saves the file to your Google Drive.

No install. Runs in the browser. Reading and saving all happen inside your own Google account. Event Dropper has no server and holds none of your data.

Before you start

All you need is a Google account.

What you need	Notes
Google account	For Calendar and Drive
Browser	Chrome / Edge / Safari, etc.
Event document	PDF or image (JPG / PNG)

How it works

1Sign in

Click "Sign in with Google" and choose your account.

The Sign in with Google button — Click "Sign in with Google"

Google will ask for permissions. Dropper requests only these three:

Calendar events — to create the tournament event
Drive files created by Dropper — to save the event document
App configuration data — to remember your settings

Google consent screen listing the three permissions — The consent screen — only three permissions

2Drop the event document

Drag and drop the event document PDF or image onto the drop area. You can also click to choose a file.

3Check the results

The tournament name, date, venue, events and more are read automatically and shown on a card. Always check the results here. Anything wrong can be fixed on the spot.

4Register

Click "Register" and everything goes to your Calendar and Drive.

The registration complete message — Done

What gets registered

Where	What
Google Calendar	The tournament-day event (name, time, venue)
Google Drive	A folder tree `<Year> Tournaments / <Month> / Tournament name /` in My Drive (e.g. `2026 Tournaments / 09 /`), with the event document inside

Google Drive folder structure: year, month, tournament name — The folders created in Drive

Using AI (optional)

For better reading accuracy you can use AI (Google Gemini). It's entirely your choice. The basic reading works without it.

Turning AI on

After signing in, a popup asks whether to use AI. Choose "Use AI" and the API key screen opens.

Getting an API key

Open Google AI Studio
Sign in with your Google account
Click "Create API key"
Copy the key and paste it into Dropper

It's free and takes about 3 minutes.

🔒 Your key is stored only on your device (browser). It is never sent to the developer.

⚠️ On the free tier, submitted content may be used to improve Google's services. Do not drop confidential documents.

Your choice is remembered, so the popup won't appear again. To change it, click "AI settings" in the banner at the top of the screen.

FAQ

Is it free?: No. Everything is free to use.
Which sports are supported?: Table tennis and several other sports. Pick one from the sport selector at the top of the screen.
The reading was wrong.: You can edit the card directly before registering. Some document layouts are harder to read; using AI often helps.
How do I delete a registered event?: Delete it from Google Calendar and Drive as you normally would. Dropper has no delete function.
Is my data sent anywhere?: No. Event Dropper has no server. Only when you use AI mode is the text of your event document sent to Gemini, using your own API key. See the privacy policy for details.
