knoyu is an AI with perfect long-term memory. Unlike chatbots that forget everything between sessions, knoyu remembers every conversation forever, detects contradictions in what you say, and tracks how your emotions evolve over weeks and months. It's not an assistant — it's a confidant.
ChatGPT forgets you the second you close the tab. knoyu never does. It extracts structured memories from every conversation — facts, feelings, decisions, goals — with timestamps and emotional context. It catches you when you contradict yourself ('wait, you said you'd never quit that job'). And it visualizes your emotional arc over time so you can see patterns you'd never notice yourself. No other AI does all three.
knoyu's contradiction detection notices when your story changes. If you said in January you'd never leave your job, then in March you're talking about quitting, knoyu will surface that. It's not judgmental — it asks the right questions to help you understand your own evolution.
knoyu tracks the emotional context of everything you share — not just what you said, but how you felt when you said it. Over weeks and months, this builds an emotional arc: a visualization of how your feelings about relationships, work, goals, and life have shifted over time.
Yes. Every detail you share is distilled into structured memories with timestamps, emotional context, and semantic connections. Nothing fades unless you choose to delete it. You can also use Forget Mode for conversations you don't want saved, or Secret Mode for memories only you can access.
knoyu never trains on your data. Your conversations and memories are yours alone. You can export everything as JSON or Markdown anytime, and delete any or all of your data from Settings. All data is encrypted in transit and at rest.
