Add Stackey on LINE and drop photos, videos, and documents straight from your chat.
Add on LINEDrop photos, videos, and documents straight from WhatsApp — same automatic naming and filing.
Add on WhatsAppNo naming. No folders. No more thinking.
The moment you save a file, it's renamed, sorted, and ready.
"IMG_4521.jpg" becomes "Spring_Walk_With_The_Dogs.jpg". "document_final_v3.pdf" becomes "Contract · $1,000 · 2026/03". Stackey reads what's inside and gives it the right name — automatically.
No folders to create or choose. Receipts to receipts. Photos to photos. Contracts to contracts. The moment you save, it's in place.
Receipts, invoices, contracts, photos, videos — identified instantly. Dates and amounts extracted automatically.
PDF, Word, Excel, PowerPoint, images — you know what's inside without clicking.
MP3, MP4, MOV — play right where they sit. Up to 2 GB.
MP3, MP4, MOV — play right where it sits. No download. Files up to 2 GB stream in full. And voice messages from WhatsApp, Slack, or LINE? Stackey listens, understands what was said, and gives the file a name that means something. Voice memos, meetings, video footage — no need to open anything.
Adobe Illustrator files are previewed too — without launching Illustrator. PDFs, images, Word, Excel, PowerPoint: just scrolling, you sense what each one is. For creative teams, no more waiting.
Stay on the preview screen and send with one click. No mail app to launch. No subject to write. Type the recipient. Hit send. That's it. The recipient sees a clean email — your name, the file name, and an "Open File" button.
You don't search by file name. You search by memory. "That contract from last spring, the company with the blue logo." "The invoice I sent Amy last month." Speak in fragments of memory, and Stackey finds it in seconds.
Drop in a Thai invoice, and it's saved as "Somchai Co._Purchase Invoice_฿45,000_March 2026.pdf" — in your language, with key details attached.
The original stays untouched. But you search in your language, with your memory.
Works in any language. Saves in yours.
Stackey Web is a PWA built for PC, tablet, smartphone, and LINE.
Open it in your browser, or add it to your home screen or Dock to launch like a native app.
No downloads. No installations. Always the latest Stackey.
If you use Stackey on LINE, signing in on your PC is effortless.
No email, no password.
Just send the 6-digit code shown on your PC to LINE.
The same sign-in works over WhatsApp, too.
(You can also sign in with Email, Google, or Apple.)
Whatever comes to mind — type it or speak it out loud. Stackey writes the title, the summary, and files it into a folder automatically. Forward a text to yourself on LINE, and it lives here as a memo too. "I'll write it later" stops disappearing.
For what you truly don't want seen, just switch the whole folder to Private.
It disappears completely from the list — kept safe.
It appears only when you enter your PIN (4-digit code). You reach it only when you want to.
Forgot your PIN? No problem — reopen it easily via your registered LINE, email, or WhatsApp.
Stackey gets things in order, on its own. But when a title doesn't quite fit,
rewrite it. Teach Stackey the names that matter to you.
Choose the quality that suits the moment.
When the auto-generated title or summary isn't quite right, rewrite every character. "Mom's birthday flowers." "Contract — Suzuki-san." Whatever helps you find it later, that's what it becomes.
Register the people and pets you love, and Stackey writes them into titles and summaries the moment they appear. Not "a black dog" but "Coco." Not "with a friend" but "with Miki." Search later, find instantly.
Photos: Standard (Full HD) / High (4K) / Original. Videos are saved at their original quality with no compression. Keep family memories full resolution; keep daily notes light.
How it counts: Photos — Standard = 1 Stack / High = 2 / Original = 4. Videos — by length (≤1 min = 1 / 1–3 min = 2 / 3–7 min = 4 / 7+ min = 8). Documents, audio, memos = 1 Stack. The app shows "This save uses N Stacks" before each upload.
Quick Look that lives in the cloud, names your files for you,
and remembers your searches. That kind of place.
PDF, Word, Excel, PowerPoint, video, audio, photos, Adobe Illustrator — preview them right inside Stackey, no native app required. Thumbnails are generated automatically the moment you drop a file in.
"the design with the blue cover," "last month's restaurant receipt." Search by memory, not by string match.
Filename, document type, client, summary — generated automatically the moment you drop a file in.
Open, check, email it. No app switching — the whole flow lives in one screen.
A Japanese invoice, a Chinese menu — whatever language the file is in, Stackey saves a summary in yours. No more lost-in-translation.
Same experience. Same files. Phone, tablet, PC — all in sync.
Now on iPhone, iPad, Mac, Windows, and Android.
