Human-in-the-loop (HITL) agents are AI systems that pause to get a person's approval, correction, or input before taking consequential actions.
ApplicationsAgent guardrails are the safety rules, filters, and limits that constrain what an AI agent is allowed to do, say, or access.
ApplicationsAI meeting notetakers join your video or audio calls, transcribe everything spoken, and automatically produce summaries, action items, and searchable records.
ApplicationsRecommendation systems are the AI engines that decide what you see next: the movie Netflix surfaces, the product Amazon suggests, the next video on YouTube.
ApplicationsAI fraud detection uses machine learning to spot suspicious transactions, accounts, and behaviors in real time, before money disappears.
ApplicationsAnomaly detection is AI that learns what 'normal' looks like and then flags anything that doesn't fit, from a failing machine to a network intrusion.
ApplicationsAI slide generation turns a prompt, outline, or document into a formatted presentation deck in seconds.
ApplicationsAI browser automation lets a model see and control a web browser, clicking, typing, and navigating like a person to complete tasks.
ApplicationsAI data extraction pipelines turn messy, unstructured sources like PDFs, emails, and scanned forms into clean, structured data.
ApplicationsAI test generation uses machine learning and large language models to automatically write software tests, freeing developers from tedious manual work.
ApplicationsAI demand forecasting predicts how much of a product or service customers will want, using machine learning to crunch sales history, prices, weather…
ApplicationsAI personalization engines tailor what each user sees, from product recommendations to homepage layouts, by learning individual tastes from behavior.
