Generic AI Makes Things Up. You Need Answers You Can Trust.
ChatGPT pulls from everywhere and cites nothing. You ask a specific question about your research, your documents, your field — and get a confident-sounding answer that might be completely wrong. There's no way to verify it. That's not intelligence. That's a liability.
AI That Knows Its Limits
myCodex only answers from your uploaded materials. If the answer isn't in your sources, it says so.
Zero Internet Knowledge
No web scraping. No general training data. No Wikipedia summaries. The AI is completely isolated to the materials you provide.
Upload Anything
PDFs, YouTube videos, audio recordings — any source material you trust. Build a knowledge base from exactly the content you choose.
Citation-First Answers
Every response includes clickable citations — PDF page numbers, video timestamps, audio segments. Verify every claim in seconds.
Three Steps. That's It.
