# rudra496/stealthhumanizer architecture > Architecture diagram of the GitHub repository rudra496/stealthhumanizer, generated by GitDiagram from its file tree, README and a sample of source files (last updated 2026-09-26). It is an AI-made overview: check details against the source. - Interactive diagram: https://gitdiagram.com/rudra496/stealthhumanizer - Repository: https://github.com/rudra496/stealthhumanizer ## Overview StealthHumanizer is a web app and API for rewriting AI-generated text, checking its AI-likeness, and refining or exporting the result. The main workflow runs from the writing UI through the humanization API, which selects a provider or hosted model, rewrites text, and returns detection and fidelity assessments. Separate branches provide detection, grammar, batch work, file upload, and sentence refinement. The README documents additional provider and style options; the graph focuses on runtime paths supported by the sampled source and tree.
