One Swiss Knife in the exact shape of your life.

Lesson Planner

A private lesson planner 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.

Sunday evening, kitchen table, next week's lessons circling in your head like planes waiting to land. Lesson Planner gives each one a place: the lesson, its date, and the objectives and plan written out where Thursday-morning-you can find them. The teaching is yours; this just makes sure the plan survives until it's needed.

What it keeps

Standing facts

In ten years

Whatever you put in (Lesson, Date and Objectives & plan) 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 lesson planner 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 Lesson, Date and Objectives & plan 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

01

How does the Lesson Planner organise my week?

One entry per lesson: its name, its date, and a free-form space for objectives and the plan itself. Line them up by date and the week stops circling and lands.

02

Is the Lesson Planner tied to a particular curriculum?

No — the objectives and plan field is yours to fill however your school, subject, or country requires. It holds the plan; it doesn't have opinions about it.

03

Does the school's IT department need to approve this?

There's mercifully little to approve: it's one HTML file that runs offline in your browser, with no account, no server, and no student data going anywhere. Your plans stay on the page, and the file is yours forever.
