About these tools
The calculators run as plain JavaScript in your browser. They do exactly what they describe and they never send anything anywhere. The AI-assist tools generate ready-to-paste prompts you can use in any AI tool of your choice; the structure encodes practice-area guardrails (operator perspective, jurisdiction-aware caveats, what to verify with counsel).
The goal is to close the gap between what a non-lawyer needs to understand before signing and what they can reasonably get without buying an hour of attorney time. None of these are legal advice. None of them create an attorney-client relationship.
