About bcat
bcat is an AI chat agent built around a simple idea: a truly useful AI assistant shouldn't require you to hand over your conversations to a corporation. The mascot is Brody — a real tuxedo cat in smart glasses — and the project is named after him.
Why privacy matters here
Most AI chat products work by sending every word you type to a remote server, processing it through a company's model, and returning a result. Your questions, your ideas, your half-formed thoughts — all of it logged, potentially used for training, and subject to that company's data policies.
bcat sidesteps all of that. Processing happens on the machine running bcat. If you're using the hosted version at chat.bcat.app, your conversations are stored only there — never forwarded to any third-party AI service. No OpenAI. No Anthropic. No Google. Just bcat.
What bcat can do
Research & information
bcat doesn't just answer from memory — it looks things up. It can search the web in real time, read the full text of any page you point it at, and pull results from Wikipedia, Hacker News, the Wayback Machine, and Wiktionary. Ask it to find academic sources and it searches arXiv, PubMed, and OpenAlex and summarises the papers for you.
Code & math
bcat writes code in any language, explains what existing code does, and can run it in a safe sandbox to show you the actual output rather than guessing. For mathematics — from algebra to proofs — it routes automatically to a dedicated math specialist that reasons step by step.
Images
Upload a screenshot, a photo, a diagram, a handwritten note — anything visual. bcat analyses it and answers questions about what it contains.
Memory
Tell bcat something once and it remembers across conversations. You can ask it to recall, search, or remove things from memory at any time. Memory is yours — bcat won't silently forget it, and it won't silently use it for anything you didn't ask for.
Domain specialists
Not every question needs the same kind of answer. bcat automatically routes hard questions to domain specialists: dedicated reasoning tracks for mathematics, coding, biology, security, science, and ancient history. You don't have to tell it which one — it figures that out.
Developer tools
bcat can search GitHub repositories and Stack Exchange threads, explain error messages, suggest fixes, and help debug problems — all without leaving the conversation window.
Translation
Translates text across dozens of languages and goes beyond word-for-word substitution — it explains idiomatic meaning, tone, and context when those things matter.
Live facts
Current weather, country profiles, time zones, word definitions — bcat pulls these from live sources so the answer reflects right now, not whenever the training data was collected.
Self-improving over time
bcat runs a nightly loop where it probes its own reasoning, identifies patterns it handled well, and stores those patterns for future conversations. It gets sharper the more it's used, without requiring you to do anything.
Who builds it
bcat is a privacy-first tool built on the principle that useful software shouldn't require you to trust a corporation with your data. bcat is free for individuals.
