Pick the tool you need

These tools are built for quick classroom decisions: choose texts with more confidence, and prioritize writing feedback faster.

Reading Text Analyzer

Estimate the reading level of a passage and get a practical snapshot of text complexity for classroom use. Results are framed as signals (not pass/fail) so you can match texts to your students.

Open Analyzer About + How to Interpret Results
Good for: grade-band fit • read-aloud vs partner vs independent reading • spotting sentence spikes that may need chunking

Student Writing Checker

A fast snapshot for grading. Flags patterns that often reduce clarity: sentence boundaries, mechanics cues, and writing load. Designed to help you prioritize feedback efficiently.

  • Plan reading mode: decide if a passage is better as read-aloud, partner reading, or independent reading.
  • Grade faster: spot sentence-boundary patterns (run-ons / fragments) and mechanics cues that often affect clarity.

How to interpret results (quick guidance)

Reading Text Analyzer: what the main numbers mean
  • FKGL: a readability estimate driven mostly by sentence length and word syllables.
  • Grade band: a teacher-facing suggestion that should be adjusted for your students.
  • Other signals: punctuation density, long-word ratio, and sentence spikes help you spot where students may need chunking, modeling, or vocabulary support.
Student Writing Checker: what to use first
  • Sentence-boundary flags: run-on and fragment signals often explain “hard to follow” writing quickly.
  • Writing load: longer sentences and heavy punctuation can raise cognitive load and reduce clarity.
  • Mechanics cues: quick indicators to prioritize where feedback will improve meaning most.
  • AI-pattern signal: an advisory consistency signal meant to prompt a closer look when needed.

FAQ

Do I need an account?

No. Open the tool and use it immediately.

Is the text stored anywhere?

No. The tools run locally in your browser.

Can I upload Google Docs or Word documents?

Upload supports .txt only. For Google Docs or Word, copy and paste the text into the tool.

What should I do if the grade band feels off?

Use grade band as a starting point. Adjust based on your students’ decoding ability, background knowledge, and reading mode (read-aloud vs independent).

Where can I learn what each metric means?
