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.
AI NOTAM decoder that turns dense aviation notices into actionable briefings
Raw NOTAM messages are rewritten into a one-sentence plain-language summary backed by structured fields such as affected service, traffic type and time window.
Briefings combine route, time applicability, runway context and aircraft profile so only notices relevant to the planned movement are surfaced.
Upload a flight roster once and Notamify stores it, then auto-schedules email briefings and regenerates flight-plan briefings on demand.
Track many airports at once and receive email alerts filtered by effect, category, ICAO code, day of week or time of day.
