AI-Generated Content and Critical Disclaimers

Nature of AI-Generated Content

THE GUIDANCE, INSTRUCTIONS, RECOMMENDATIONS, STEPS, SAFETY WARNINGS, DIFFICULTY RATINGS, TIME ESTIMATES, COST CALCULATIONS, TOOL LISTS, AND ALL OTHER CONTENT PROVIDED BY OUR SERVICE IS GENERATED BY ARTIFICIAL INTELLIGENCE AND MAY CONTAIN ERRORS, INACCURACIES, OMISSIONS, OR INAPPROPRIATE RECOMMENDATIONS.

CRITICAL: AI-GENERATED SAFETY WARNINGS MAY BE INCOMPLETE, INSUFFICIENT, OR COMPLETELY INCORRECT. DO NOT RELY ON AI-GENERATED SAFETY WARNINGS AS YOUR SOLE SOURCE OF SAFETY INFORMATION. ALWAYS CONSULT PROFESSIONAL SAFETY GUIDELINES, MANUFACTURER INSTRUCTIONS, AND QUALIFIED EXPERTS.

Our AI models are trained on large datasets and may:

Provide incorrect or incomplete instructions that could lead to injury or death
Suggest inappropriate methods or materials that create safety hazards
Misidentify problems or situations in ways that could cause harm
Offer guidance that is not suitable for your specific circumstances and could be dangerous
Generate safety warnings that are insufficient, inaccurate, or missing entirely
Fail to warn of significant risks or hazards, including risks of death or serious injury
Provide outdated or non-current information that no longer meets safety standards
Misinterpret uploaded images or descriptions, leading to dangerous recommendations
Make errors in calculations, measurements, or specifications that could compromise safety

No Professional Verification

We do not employ licensed contractors, mechanics, electricians, plumbers, or other professionals to verify the accuracy, safety, or appropriateness of AI-generated content.
