Thinking in algorithms

Computational thinking starts with a simple question: how can we turn a problem into a series of clear, repeatable steps?

01 / The main idea

A process, not just an answer

An algorithm takes an input, follows a sequence of instructions, and produces an output. Different approaches can solve the same problem with very different amounts of work.

Start with Scratch

Visual blocks make the logic visible: combine conditions, loops and functions to build an interactive program.

From a video to a reusable note.

  1. Choose a source

    Paste a supported link in the Web workspace. Use Companion when browser assistance is needed.

  2. Generate and review

    AI prepares the note automatically. Follow timestamps to check details against the video.

  3. Revisit or export

    Read your saved note in your library or download it for your own knowledge tools.

More useful after the video ends.

01

Find the idea again

Structured sections and timestamps help you return to the part that matters.

02

Build a personal library

Search your saved notes and reopen them without starting another generation.

03

Keep your own copy

Export Markdown. When a note includes images, keep its assets folder alongside it in Obsidian.
