Readability Analyzer

What it does

Readability Analyzer is a deterministic tool that evaluates the reading difficulty of text or documents. It accepts plain text, TXT, Markdown, HTML, PDF, and DOCX files. The analysis returns 11 standard readability formula scores (e.g., Flesch Reading Ease, Gunning Fog, SMOG), a grade band estimate, sentence-level flags for hard and very hard sentences, and comprehensive text statistics (word count, unique words, syllables, reading time, etc.). It also identifies score drivers—factors that most influence readability—and lists long words, many-syllable words, and adverbs per sentence. The tool is available as an Apify Actor with pay-per-event pricing ($0.01 per 1,000 analyzed words).

Who it is for

This tool is designed for content creators, editors, technical writers, educators, and developers who need to assess the readability of documentation, help-center articles, landing page copy, policy drafts, classroom material, or any written content. It is particularly useful for teams that want to integrate readability checks into automated workflows via the Apify API, schedules, webhooks, or dataset exports. The tool does not require any login, AI model, or third-party API key.

Why it matters

Readability directly impacts user comprehension and engagement. By providing multiple formula scores and granular sentence-level evidence, Readability Analyzer helps writers identify overly complex sentences and adjust their content for the target audience. The deterministic nature ensures consistent, reproducible results—no AI hallucinations or subjective judgments. The ability to process uploaded files (including PDFs and DOCX) makes it easy to incorporate into existing content QA pipelines. However, note that scanned or image-only PDFs are not supported (no OCR).

Launch signal

The Actor was first released as version 1.0 on Apify Store. It is maintained by the community and has 2 total users (1 monthly active) as of the available data. The developer, Maxime Dupré, offers support and claims to fix issues within 24 hours. The tool is listed alongside related Actors like Webpage Text Extractor and Profanity Checker, suggesting a suite of text-processing utilities.

Brand and naming

The name "Readability Analyzer" is straightforward and descriptive, clearly communicating the tool's function. It is memorable and easy to find via search. The branding on Apify Store is minimal, relying on the platform's standard layout. The developer's personal brand (Maxime Dupré) is present but not emphasized. The tagline "Analyze text readability with scores, grades, and word statistics via API" effectively summarizes the core value proposition.
