Moonshot AI's long-context assistant for research, coding, and agentic work
Feed in lengthy documents, papers, or code and ask questions across the full text without losing earlier context.
Hand over multi-step jobs that involve planning, browsing, and tool use instead of only single-turn answers.
Generate structured research reports, slide decks, and formatted documents directly from your prompt or source files.
Extend capabilities with plugins and set recurring jobs so the assistant keeps working between sessions.

An AI journaling companion that listens, responds, and remembers your story
Instant Chat replies on the next line as you write, and one-tap actions like Go Deeper or Get Perspective give you a fresh angle without leaving your journal page.
Talk out loud in a real-time back-and-forth and save the transcript, or simply dictate an entry and let Reflection transcribe it.
Natural-language search across everything you have written, so you can ask about patterns, people or a specific period and get a plain-language answer.
Structured programs on gratitude, anxiety, relationships and productivity, plus journaling templates, daily reminders and nine light/dark color themes.
