Completely free
Your AI free tier is sitting idle.
Put it to work here.
Your Google account refills a free AI allowance every day. Left alone, it simply expires. No credit card, no cost, about three minutes — and it goes straight into what Dropper reads for you.
※ Dropper works fine without a key. AI mode is optional.
Series
Tools you use simply by dropping in a file. Pick the one that fits what you want to do and start right away.
Just drop in the event document (PDF or image) and the date and venue are added to Google Calendar automatically. You can also create ready-to-post WhatsApp/SNS announcements from the details in one tap. Works for any event.
Completely free
Drop one sheet — a year planner, a fixture list, a season calendar — and every entry on it is read at once. Check the list, then add them all to Google Calendar in one go. Calendar-grid layouts work too.
Completely free
Drop a chat screenshot, meeting notes or minutes, and it sorts them into what was decided, what is still open, what to do, and a record of what already happened. No more scrolling back to ask what you actually settled. Handwritten notes and photos of a whiteboard work too.
Completely free
Drop a blank tournament entry form (Excel), pick the players from your club roster, and it fills in gender, date of birth, age, address and phone number. You can build the roster here too, with addresses filled in from the postcode. Made for Japanese entry forms (the tool is in Japanese only).
Completely free
🙋 Attendance
Collects and counts replies from your members. Start it from an event you just read, or on its own without any document. Members pick their name from the roster and tap yes / maybe / no - no app and no sign-up.
Start it from “🙋 Just collect attendance” on the first screen. It is still a preview, so screens and steps may change.
PLAYGROUND
Drop a photo and a monster card is born.
The inside of your fridge, a view from your walk, your desk. Every photo gives birth to a one-of-a-kind card. Drop two or three at once to fuse them, or marry a male card and a female card to have children. Not a tool — just for fun.
Play Monster DropperAI Mode
No more copy-paste, over and over.
AI mode reads more accurately, and it is the only way to read grid-style calendar planners. All it needs is one API key, free from Google. No credit card registration involved.
Notes
Every tool is free, so anyone can give them a try. In return, please note the following before you start.
Every tool is published free of charge. Pick only the ones you need.
Because the tools are free, we don't offer one-on-one support. Please refer to each tool's guide for how to use it.
There's no support, but tools are improved from time to time, and new information is delivered to you automatically from the tool.
About
“Just drop in a file, and the hassle is handled.” We call these little tools Dropper, and we build and release them as a series. There are three so far. One reads an event document, adds the date and venue to Google Calendar, and writes the WhatsApp/SNS announcement for you. One reads a single sheet with many dates on it — a year planner, for example — and puts them all into your calendar at once. One takes a chat screenshot or a page of meeting notes and sorts it into what was decided, what is still open, what needs doing, and a plain record. They all work the same way — just drop — so anyone can use them, not only a particular group or sport.
Alongside them there is Attendance. The others take a sheet of paper and get something out of it; this one collects from people instead. The direction is reversed, so it sits on its own shelf. Members pick their name from the roster and tap yes, maybe or no — no app, no sign-up, no login. You can start it from an event you just read, or on its own with no document at all. More tools will be added over time.
