Heavy friction: this sample scores 64/100 on a simple friction scale built from sentence length, advanced-word density, and long-word share.

Reading friction

Heavy friction

Directional estimate of how much the text may interrupt reading flow.

Friction score

64/100

Built from structure plus vocabulary density.

Advanced-word share

35.7%

Estimated B2-C2 vocabulary in the sample.

Long-word share

25.0%

Words with 8+ characters.

Takeaways

This sample is dense enough that reading flow may break often. Anki can support it, but only if you filter hard and keep expectations realistic.

Because the sample is short, use the score as a comparison aid rather than a precise label.

The score was driven more by general density patterns than by explicit signal-word matches.

Matched signals

No strong signal words detected in this sample.

How to interpret this tool

A text does not need to be officially advanced to feel slow. Reading friction appears when structure, vocabulary density, and word shape combine to interrupt flow again and again.

This tool gives that density a single practical score so you can compare candidate texts before they become an extraction project.

Usage notes

Treat short samples as directional only. The tool becomes more useful when the text reflects the real body of the book.

If vocabulary looks manageable but the text still feels hard, syntax or topic familiarity may be doing the damage.

Use the result to compare texts against each other, not to pretend the score is an official assessment.

FAQ

What is reading friction?

It is a practical estimate of how often the text may break your momentum through dense syntax, advanced vocabulary, or visually long words.

Is a higher friction score always bad?

Not always. It depends on your goal. High-friction texts can still be useful, but they usually require more patience and stricter extraction discipline.
