手寫筆記、PDF 註記與 AI 學習工具，都在同一塊畫布上
低延遲墨跡、防誤觸手掌辨識、劃掉即擦除以及手寫轉文字，讓書寫接近紙筆手感。
匯入合約、論文或教材，用手直接標註，註記可搜尋並可乾淨匯出。
同時檢索鍵入文字、手寫與速寫，並把筆記轉成摘要、心智圖或結構化計畫。
在共享筆記本、文件和白板上同時協作，不再有版本衝突或反覆傳檔案。
Openlayer is a platform that tests AI systems before release, monitors them in production, and enforces policy and compliance requirements across every model and agent your company runs.
Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.
