The document introduces Tripnary, a new tool for searching for flights within the workplace communication platform Slack. It allows users to find flights by sending messages to Tripnary like "/tripnary find flights from NYC to AUS leaving 4/8". Tripnary searches millions of flights from Skyscanner to provide the cheapest fares. It understands both structured phrases and natural language for flight searches. Future updates will expand its capabilities to include hotels and more natural language queries.
