+Is DayPage free?
Yes. The app is free. You bring your own LLM key (OpenAI, DeepSeek, or Aliyun DashScope), so the only running cost is your AI usage — usually under $1/month for typical journaling.
+Where does my data live?
On your device, as Markdown files inside a vault folder. You can open it in Obsidian, copy it to a USB stick, or back it up to any sync service you trust.
+Do you train on my journal?
No. We never train models on user data. Your raw memos never reach our servers — they go directly from your device to the LLM provider you configured.
+What does AI actually do?
Every night around 2am, AI reads the day's raw memos and produces: a structured diary page, entity pages for people/places/projects mentioned, and links into your growing knowledge graph. You review in the morning.
+Which models do you support?
OpenAI (gpt-4 / gpt-4o), DeepSeek (deepseek-chat / deepseek-reasoner), and Aliyun DashScope (qwen3.5-plus). Whisper for voice transcription. All configurable.
+Does it work offline?
Capture works fully offline. Voice, text, photo — all queued locally. Compilation needs network to reach the LLM. We surface a quiet banner when something is queued.
+Is there a web version?
Web is read-only for now — you review compiled pages at daypage.app/today. iOS is the primary capture surface. macOS is in private beta.
+Can I export everything?
Your vault is already exported — it's just a folder of Markdown files. Nothing is locked in a proprietary database. Drag the folder, copy it, version-control it.
