Geometry and math
A construction where the bisector really bisects, with its points lettered the way the textbook letters them.
Features Diagrams
Diagrams drawn exactly, part by part.
Chasca draws the diagrams a lesson needs, exactly: tables, geometry constructions, family and decision trees, flowcharts and code, alongside graphs, worked equations, force diagrams, timelines and bar charts. Every one is computed, not sketched, so a bisector really bisects and a table’s columns line up, and each part appears as the narrator says it.
On every plan and in every language, right to left in Arabic.
How it works
A diagram in your video, in four steps.
- 1
Describe it, or paste it
Paste the table, the triangle and its measures, the steps of a process or the code. A photo of a worksheet works too: it is read in full.
- 2
Chasca works it out
Points, angles, rows and branches are computed exactly: midpoints, bisectors and perpendiculars land where they really fall.
- 3
Watch it draw
The diagram builds as it’s explained: a table’s header, then each row as it’s spoken; a construction one line at a time.
- 4
Change one thing
Turn on subtitles, switch the style or add music, free. The diagram and the narration stay exactly as they were.
What people use it for
For lessons that need the real figure.
Science and data
A classification tree, a comparison table or the numbers from your document, each row drawn as it’s spoken.
Computing and logic
Truth tables, flowcharts with decision diamonds, and code written out line by line.
Yes. Chasca draws tables, geometry constructions, family and decision trees, flowcharts and code, as well as graphs, worked equations, force diagrams, timelines and bar charts. Each one is computed, not sketched, and each part appears as the narrator says it.
Yes. A construction is drawn to scale, without stretching, and every point built from others is computed exactly: midpoints, the feet of perpendiculars and where an angle bisector meets the opposite side. Each letter sits outside the shape, clear of the lines.
Yes. Upload the document, or a photo of the page, and ask for the table in your request. It is drawn with its header first, then each row as it is spoken, with long cells wrapped and numbers lined up.
Yes. A code excerpt is written out line by line, exactly as you gave it, in a monospaced face with light coloring. It is never translated, even in a video in another language, and always runs left to right.
Yes. On an Arabic board, a table’s first column is on the right, a tree’s first branch is on the right and a flowchart starts on the right. Words in Latin letters inside them, such as “A AND B”, still read left to right. More on Arabic math.
