Sound and Rhythm

Lexica Reader analyzes the physical sounds of your essay by focusing on syllabic accents within sentences and physical patterns between sentences.

Emotional Context

Lexica Reader analyzes how human readers might perceive your essay by focusing on the use of fancy-sounding prestige words and the emotional sentiment of your writing.

Lexica Reader finds and highlights common stylistic quirks that could potentially weaken your writing, representing them in an easy-to-navigate visual display.

Submitting an essay

Navigate to the front page and paste your essay into the large text box. Including a title is optional but makes it easier to organize your essay. Click on the "Analyze" button and wait for your essay to process.

Viewing an essay

After processing, you will be able to view and edit your essay freely. The righthand panel contains information about the measured attributes of your essay, including an overall score. A score closer to 100 percent is more ideal.

Viewing an essay's statistical breakdown

Lexica Reader shows you how your particular essay scored on certain heuristics and compares it to an ideal essay using a normal distribution model. A value of 0 percent is generally undesirable and a value of 100 percent is near-ideal.

Managing an essay's suggestions

By default, Lexica Reader will highlight parts of your essays in different colors in order to indicate certain stylistic quirks that may or may not harm the quality of your essay. To turn off certain highlighted suggestions, simply click on the toggle buttons.
