DRAFT — pending licensed-attorney ratification.

This is a working DRAFT. Nothing on this page is final, and nothing here is legal advice. Every word below must be reviewed, corrected, and ratified by a licensed attorney before it is published or relied upon. Bracketed placeholders — [EFFECTIVE DATE], [STATE OF INCORPORATION], [CONTACT], [ARBITRATION BODY] — mark facts that counsel must confirm. Enforceability of any limitation, waiver, or disclaimer below depends on your jurisdiction and must be verified by counsel.

Stesso Safety & AI-Content Disclaimer

Last updated: [EFFECTIVE DATE] Applies to: the Stesso website (stesso.com), the Stesso mobile app, the Stesso AI chat and AI-generated project and step guidance, the Stesso assistant embedded or displayed on third-party merchant websites and storefronts (for example, Shopify stores), Stesso brand-demonstration sites, the Stesso public/partner API, Stesso creator tools and automated creator-voice replies, and any Stesso content that appears in search engines, AI assistants, or other answer engines.

This is the standalone safety page that our in-product safety notices link to. Please read it before you act on anything Stesso shows you. If anything here conflicts with the Stesso Terms of Service, the Terms of Service control; this page explains the safety points in plain language. See the Stesso Terms of Service and Privacy Policy.

1. The one thing to remember

Stesso's guidance is generated by artificial intelligence. It can be wrong, incomplete, out of date, or unsafe. It is not reviewed by a qualified professional. It is not professional advice. You use it at your own risk.

Everything else on this page expands on that single point.

2. What Stesso is — and what it is not

Stesso is an AI-powered tool that helps you plan do-it-yourself ("DIY") projects. It generates project ideas, step-by-step instructions, tool and material lists, and matches videos to steps. It runs on the Stesso website and app, inside chat, inside assistants embedded on other companies' websites, through our API for approved partners, and in content we publish to video platforms and search/answer engines.

Stesso is NOT:

  • a licensed electrician, plumber, gas fitter, mechanic, structural engineer, contractor, architect, or building inspector;
  • a doctor, nurse, pharmacist, dietitian, allergist, poison-control center, or any other medical or health professional;
  • a substitute for the manufacturer's instructions for any product, tool, appliance, vehicle, or material;
  • a substitute for your local building codes, permit requirements, or inspections;
  • a substitute for hiring a licensed, insured professional to do work that could hurt you, hurt someone else, or damage property.

No professional relationship is created by using Stesso. Using Stesso does not create a contractor, engineer, medical, legal, or other professional relationship, and no Stesso output should be treated as the advice of a licensed professional.

3. AI can be wrong, and no human checks it first

Stesso's instructions, warnings, tool lists, measurements, and video matches are produced automatically by AI models. Please understand all of the following:

  • The AI can be confidently wrong. It may state something as fact that is incorrect, unsafe, or dangerous. It can invent steps, skip critical safety precautions, recommend the wrong tool or material, or misjudge how risky a task is.
  • No qualified professional reviews the output before you see it. Stesso content is not pre-screened by an electrician, mechanic, engineer, doctor, or other expert. Where a person reviews certain content, that is noted; everything else is unreviewed AI output.
  • The AI may not know your specific situation. It does not see your actual wiring, your specific appliance model, the real condition of your vehicle, your home's structure, your health conditions, or your local rules. Guidance that is fine in general can be wrong or dangerous for you.
  • The AI may be out of date. Codes, product instructions, recalls, and safety standards change. The AI may not reflect the current version.
  • Safety warnings the AI generates are themselves AI-generated and unverified. A "Safety Warning," "Tip," or "Caution" that appears inside Stesso guidance is also produced by AI and may itself be wrong or incomplete. Do not treat the absence of a warning as a sign that something is safe.

Always verify before you act. Check Stesso's guidance against the manufacturer's instructions for your exact product, against your local building codes and permit requirements, and against a qualified professional — and stop if anything does not match or you are unsure.

4. You assume all risk

By using Stesso and acting on its guidance, you accept that you are responsible for what you do. You are responsible for deciding whether a task is safe for you to attempt, for working safely, for using the right tools and protective equipment, for following manufacturer instructions and local codes, for pulling any required permits, and for the results.

If you are not fully confident you can do a task safely and correctly, do not attempt it — hire a licensed, insured professional. When in doubt, stop.

This assumption of risk is part of your agreement with Stesso. See the Terms of Service for the full, controlling language.

5. High-risk work — and the work we refuse to help with

Some DIY work is dangerous enough that a single small mistake can kill or seriously injure someone, start a fire, cause a structural collapse, or poison the air. We treat that work differently.

5.1 Work we REFUSE to generate do-it-yourself steps for

Stesso will not produce do-it-yourself, step-by-step instructions for the highest-hazard work. When you ask for it, Stesso declines and points you to a licensed, insured professional instead. We refuse to generate DIY steps for:

  • Natural-gas and propane work — connecting, disconnecting, moving, converting, or repairing gas appliances (ranges, dryers, water heaters, furnaces, fireplaces); running, cutting, extending, or repairing gas lines, valves, regulators, or connectors. *(Turning a gas appliance OFF at the shutoff in an emergency is a safety action, not "work" — do that and leave the building if you smell gas.)*
  • Automotive brake, steering, and airbag (and fuel-system) work — brakes, rotors, calipers, brake lines, master cylinders, bleeding; steering racks, tie rods, ball joints, power steering; airbags, SRS, seatbelt pretensioners; fuel pumps, lines, tanks, and injectors. These are systems where failure means loss of vehicle control.
  • Structural and load-bearing work — removing, cutting, or notching load-bearing walls, beams, joists, rafters, or posts; foundation underpinning; roof structure or truss changes; structural deck attachment; over-height retaining walls.
  • High-voltage and electrical service-panel work — service panels, main breakers, meter bases, service-entrance conductors, subpanel installation, anything upstream of the main breaker or on a 240V service feed, and knob-and-tube or aluminum branch remediation.
  • Defeating a life-safety device — anything whose effect is to disable or bypass a smoke or carbon-monoxide alarm, a GFCI or AFCI, a gas shutoff, a pressure-relief valve, or a brake/airbag safety interlock.
  • Food-safety and allergen safety determinations — Stesso will not tell you whether a food is "safe to eat," whether a substitution is "allergen-free," or whether something is safe for a person with a specific allergy or medical condition. Stesso can share ordinary recipes and cooking technique, but it refuses safety and allergen determinations and points you to the manufacturer's label, a medical professional, and authoritative food-safety sources.

There is no "advanced," "for professionals," "educational," or "hypothetical" version of these refusals. Claiming to be a professional does not unlock them. For this work, hire a licensed, insured professional — every time.

5.2 Other high-risk work (allowed, but with a warning)

Other work is serious but can be done more safely with proper precautions — for example, general branch-circuit electrical work on a de-energized circuit, working at height, and chemical handling. For this work, Stesso may provide guidance, but only after warning you that it is high-risk, naming the hazard, and asking you to confirm that you understand and accept the risk.

For high-risk guidance, you must be at least 18 years old. Stesso asks you to confirm your age, and you must sign in and accept the Terms before high-risk guidance is shown. If you are under 18, do not attempt high-risk work and do not use the high-risk features — get a qualified adult or a licensed professional.

Even for "allowed" high-risk work: turn off and lock out the power, gas, or water at the source; use the right protective equipment; follow the manufacturer's instructions; check your local codes and whether you need a permit and an inspection; and stop and call a professional if anything is unexpected or you are unsure.

6. Always hire a licensed, insured professional for risky work

For anything that could injure you or others, damage property, start a fire, or violate a code, the safe choice is to hire a licensed, insured professional. A professional:

  • is trained, licensed, and accountable for the work;
  • carries insurance if something goes wrong;
  • knows the current codes, permit requirements, and inspections in your area;
  • can see and assess your actual situation, which the AI cannot.

If you are weighing "save money and do it myself" against a task on the list in Section 5.1, or any task you are not fully confident in: hire the professional. Stesso can help you scope the job so you know what to ask for.

7. Verify against manufacturer instructions and local codes and permits

Before and during any project:

  • Read and follow the manufacturer's instructions for every product, tool, appliance, vehicle, and material involved. The manufacturer's instructions control over anything Stesso says. If they conflict, follow the manufacturer and stop relying on Stesso for that step.
  • Check your local building, electrical, plumbing, mechanical, and fire codes. Codes vary by location and change over time. Stesso's general guidance may not match your jurisdiction.
  • Pull any required permits and schedule any required inspections. Doing permitted work without a permit can be illegal, unsafe, and can void your insurance.

8. Emergencies

If you are facing an emergency, stop using Stesso and get real help now.

  • In a life-threatening emergency, call 911 (or your local emergency number).
  • If you smell gas, do not use any switch, phone, or flame; leave the building immediately and call your gas utility's emergency line or 911 from a safe location.
  • For a medical emergency, allergic reaction, or poisoning, call 911 or your local poison-control center.
  • For fire, electrical shock, structural collapse, or any immediate danger, call 911.
  • For risky work that has gone wrong or is beyond you, stop, make the area safe if you can do so without risk, and call a licensed, insured professional.

Stesso is not an emergency service, is not monitored in real time, and cannot help you in an emergency. Do not rely on it for emergencies.

9. This page applies everywhere you encounter Stesso

These safety points apply to every place Stesso content appears, not just stesso.com:

  • Website and mobile app — every project, step, video, clip, chat message, and AI suggestion.
  • AI chat and AI-generated guidance — anything the assistant says or generates, anywhere.
  • Assistants embedded on other companies' websites and storefronts (for example, Shopify stores) — the Stesso assistant you see on a merchant's site is Stesso's AI, not that merchant's staff. The merchant does not write, review, or vouch for its answers. The same "AI can be wrong, verify before you act, you assume the risk" rules apply.
  • Brand-demonstration sites — these are demonstrations only. They are not affiliated with, endorsed by, or operated by the named brand, and their responses are illustrative AI output, not real advice. Do not act on them.
  • The Stesso API (approved partners only) — guidance delivered through our API to vetted partners is AI-generated and not professionally reviewed; partners are required to display this disclaimer to their own users.
  • Creator tools and automated creator-voice replies — replies posted in a creator's voice on video platforms are automated AI replies operated by Stesso (and disclosed as such); they are not the personal advice of the creator and are subject to this disclaimer.
  • Search engines and AI answer engines — when Stesso content is summarized or read aloud by Google, an AI assistant, or another answer engine, it is still AI-generated DIY guidance that may be incomplete or incorrect. The safety warnings on this page still apply even if the surface you are reading or hearing does not repeat them. Verify against manufacturer instructions and local codes before relying on it.

10. No liability for outcomes

Stesso provides its content "as is" and "as available," without warranties of any kind to the fullest extent the law allows, and Stesso is not liable for what happens when you act on AI-generated guidance. The full warranty disclaimer, limitation of liability, dispute-resolution terms, and your responsibilities are in the Stesso Terms of Service, which control. In plain terms, and subject to the important exceptions below and the controlling language in the Terms:

  • You are responsible for the outcomes of work you do or have done based on Stesso's guidance.
  • Stesso does not warrant that its guidance is accurate, complete, current, safe, or fit for your purpose.
  • Stesso's overall liability to you for most claims is limited as set out in the Terms.

These exceptions are NOT capped, NOT disclaimed, and NOT waived — Stesso does not, and these terms do not purport to, limit or eliminate liability for:

  • death or bodily injury, and personal-injury safety matters;
  • Stesso's own gross negligence, recklessness, or willful misconduct; and
  • fraud.

Nothing on this page or in the Terms takes away rights you have under the consumer-protection laws of your home state that cannot legally be waived. The dispute-resolution section of the Terms includes binding individual arbitration and a class-action waiver, with a 30-day opt-out and other consumer-fair features described there; please read it. See the Terms of Service for the complete, controlling language, including the limitation-of-liability cap, the warranty disclaimer and its personal-injury/safety carve-out, indemnification, governing law, and your eligibility and acceptance obligations.
