Flashcards
A private flashcards in one HTML file on your machine: no account, no cloud, no server to talk to.
This is not a screenshot. It's the real tool, running right here: go on, put something in it.
Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.
The vocabulary you 'definitely knew' on Sunday had other plans by Thursday. Flashcards keeps the oldest study tool in the world in its simplest form: a question on one side, an answer on the other, and the humbling moment in between. Making the cards yourself is half the learning; the other half is being honest when you flip them.

- Questionshort text
- Answernotes
Standing facts
- One HTML file. Opens in any modern browser, on any operating system.
- No account. No login, no sign-up, no e-mail wall.
- No cloud. Nothing leaves your browser: no server, no telemetry, no analytics.
- Yours forever. The file keeps working whether or not Offline.Ltd does.
- Ages with use. Entries you tend keep their bloom; the years travel with the file through every reforge.
In ten years
Whatever you put in (Question and Answer) stays inside the file itself. There is no account to lapse, no plan to be sunset, no migration e-mail with a deadline in it. A decade of flashcards entries is a decade of your own handwriting, kept in a document you can back up like any other.
If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.
Getting your data out
Export to CSV from inside the tool and open it in anything: a spreadsheet, another app, a text editor. Or keep the HTML file: it is plain, readable, and inspectable; you can open it in a text editor and see your own rows sitting there. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.
Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.
Who else sees this
Nobody. Your Question and Answer never leave the file on your own disk. There is no account, no telemetry, no analytics, and no code in the file that opens a network connection, pull the cable and watch it carry on working. How privacy works across the Knowledge tools →
Questions people ask
How do these Flashcards work?
Each card is a question and an answer. You write them yourself, then quiz yourself against them — the writing plants the memory and the flipping tests it.
What subjects are Flashcards good for?
Anything that fits a question-and-answer shape: vocabulary, dates, formulas, definitions, the bones of any exam. If it can be asked, it can be a card.
Do the Flashcards work offline, say on a train?
Perfectly. The whole deck lives in one HTML file that runs in your browser with no connection and no account — your cards never leave the page, and the file is yours to keep and study anywhere.
