AI Memory
Unlike ordinary chatbots, your Second Self remembers what matters β€” always with your permission, always under your control.
Daily Diary
Every day becomes a page in your story β€” automatically written, always searchable.
What did I do this month?

  • Built the Second Humans homepage and Memory module
  • Connected Firebase authentication and Firestore
  • Set up AI Search with Google Custom Search API
Your Daily Diary pulls automatically from your Memory Timeline β€” write nothing, remember everything.
Diary entries here mirror the same data as your AI Memory Timeline β€” no extra setup needed once Firebase is connected.
File Intelligence
Upload anything β€” PDFs, docs, spreadsheets, images β€” and your Second Self remembers what's inside.
