Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.
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.
