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 installation — it runs in your browser. Reading and registration all happen inside your own Google account. Dropper has no server and never stores 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.
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
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.
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 |
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 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?
- Free for now. Paid plans are planned for the future.
- 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. Dropper has no server. Only if you enable AI, the event document text is sent to Gemini using your own API key. See the privacy policy for details.
