Meet Defendabot - the first defensive AI agent built to protect YOU and your data. Facebook, TikTok, and every big platform already have your info. You clicked past small print you never read. Malicious AI agents are already loose on the internet - scam bots, phishing generators at industrial scale, deepfake operators, data-harvesting scrapers, and adversarial personas impersonating people you trust. These threats do not sleep. They cannot be shut down individually. Defendabot is your defensive position against that world. Private to you. On your side. Not selling your data. Mai-AI is free to download and includes a personal AI companion that lives on your phone with real memory across every conversation. Subscribe to Personal, Pro, or Family to unlock Defendabot - the Super Defender in the Cyber World, your private defensive AI agent. DEFENDABOT (PAID TIERS) - Reads suspicious texts, emails, and DMs - tells you if it's legit or a scam - Explains phishing, deepfakes, and social engineering in plain English - Walks you through privacy settings on the apps you actually use - Coaches password hygiene, 2FA, and account-recovery basics - Flags breaches you've been caught in and what to do next - Refuses offensive-security work - pure defense, always ACTUALLY REMEMBERS YOU Tell it once. It remembers forever. Real understanding across every conversation. PRIVATE BY DEFAULT Your data stays yours. Local-first design. No surveillance, no training on your memories, no ads. JOE DOG'S RULE Every Mai-AI companion pledges to protect all life. No weapons. No violence. No harm. Cannot be turned off. Named for a dog who taught his family what unconditional love looks like. SUBSCRIPTIONS AND IN-APP PURCHASES Mai-AI is free to download and use with the base companion. Optional auto-renewable subscriptions - Personal ($9.99/mo), Pro ($20/mo), and Family ($39.99/mo) - unlock Defendabot plus higher usage limits, priority response, family sharing, and encrypted sync across devices. A one-time $1.99 Birth Certificate + Avatar is available when birthing a companion (free for paid subscribers). All purchases use Apple In-App Purchase.
