About Lutrakit and its maker
Lutrakit is made and published by Bastien Sulyan, a sole proprietor in Strasbourg, France. It is a focused collection of utilities designed to finish practical tasks without sending selected file contents to an application server.
Who is behind the site
Bastien Sulyan defines the product, maintains the site and takes responsibility for its published explanations. The work is practical: make each control match the underlying logic, test representative success and failure paths, document limits, and correct defects when evidence changes. No diploma, regulated title or unrelated employment is claimed here.
How the tools are checked
File-processing tools are reviewed so selected bytes stay in the browser. Automated tests exercise every published route in English, Spanish and Japanese, verify localized URLs and metadata, and use browser-level sentinels on representative PDF and audio processing paths. Tests reduce risk but do not make every output infallible, so each tool keeps visible verification and limitation guidance.
How authorship works
Published guides name a real author, show their stated editorial dates, cite primary sources for changing claims, link to the tools they explain, and record the in-house checks applied. Bastien Sulyan is the public author only for work released under his responsibility. AI-assisted translations receive a second AI quality pass and in-house spot checks; no native or external legal review is claimed.
Clear limits
Lutrakit does not claim professional authority it does not have. Tool pages state important limits: calculations should be checked, visual PDF signatures are not digital certificates, and planning tools are not medical, legal, financial or academic advice.
