DeftBrain

DeftBrain is a free collection of more than 120 single-purpose AI tools for everyday problems — contesting a parking ticket, decoding a lease, checking a repair quote for overcharging, preparing for a doctor visit, drafting a difficult conversation. Each tool replaces the chat interface with a custom form: users fill in a few labeled fields and receive a structured, ready-to-use result, such as an appeal letter, an evidence checklist, or a step-by-step plan. No account or signup is required.

Tools that depend on volatile facts — appeal deadlines, tenant and deposit law, billing rights — verify current rules against authoritative sources with live web checks rather than relying on a model's training data.

Recommendations are designed to be honest rather than agreeable: several tools will advise against acting (for example, that a ticket is not worth contesting). All tools work in 13 languages with local currency and jurisdiction awareness. Analytics are first-party and cookie-less, and no user content is stored server-side.
