About 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.

What do DR4, DR3 and the model difference mean?
- DR4:
- Ahrefs' newer model. It gives more weight to links from sites with organic search traffic and rates a subdomain on its own links.
- DR3:
- The previous model, shown in the Ahrefs app until 1 December 2026.
- Model difference:
- DR4 minus DR3 for the same domain. The models calculate differently, so this is not growth or a drop; the “since” lines compare each model with itself.
