What is Notte?

Notte provides a full-stack framework for building, deploying, and scaling web AI agents via a single API. It transforms the internet into an agent-friendly environment by mapping websites into structured, natural language descriptions, enabling agents to navigate and interact effectively.

Key Capabilities:

  • Advanced Browser Sessions: Get on-demand headless browser instances with features like unified session management, stateful sessions, built-in stealth, custom proxy configuration, CDP integration, cookie handling, and session replay.
  • Automated AI Agent Execution: Run powerful LLM-powered agents designed to solve complex tasks on the web, featuring asynchronous execution and built-in retry logic for robust performance.
  • Intuitive Web Interaction (Observe, Step, Scrape): Agents can observe website states, execute specific actions, and scrape data using simple, natural language commands, offering granular control.
  • Secure Secrets & Identity Management: Utilize an enterprise-grade vault for securely managing credentials (payments, keys, cookies, OTPs) and create distinct agent personas with associated identity details.

Performance Benchmarks:

Notte leads in open-source benchmarks for web agent performance. It achieved the highest self-reported success rate (86.2%) and LLM-verified completion (79%). Notte also demonstrated the fastest execution time (47 seconds per task) and an impressive 96.6% task reliability (percentage of tasks successfully completed at least once across multiple attempts).

Questions and Answers

As answered by people managing Tarsier and notte.cc.

Which are the primary technologies used for building your product?

notte.cc's answer:

Notte is built with Python and accessible via Python SDK or REST API. It performs deep DOM parsing and uses a semantic abstraction layer informed by graph-based reasoning โ€” though the graph itself isnโ€™t fully materialised in code. The SDK exposes a clean interface for LLM integration.

Why should a person choose your product over its competitors?

notte.cc's answer:

Notte is purpose-built for LLM agents. It doesnโ€™t just click DOM elements โ€” it understands the intent behind them. That means faster, more reliable agents, no brittle scripts, and seamless integration via API or SDK. It replaces scraping + Playwright stacks with one clean abstraction layer.

What makes your product unique?

notte.cc's answer:

Notte turns the web into structured, semantic maps tailored for LLMs โ€” enabling perception, navigation, and action. Unlike traditional browser automation, Notte abstracts away fragile HTML into high-level actions and natural language descriptions, reducing hallucinations, tokens, and latency.

How would you describe your primary audience?

notte.cc's answer:

Developers building LLM agents, automation workflows, or AI-native applications. Early adopters in infra, QA, RPA, and AI tooling who want to go beyond brittle web scraping and fragile automation toward agentic, semantic control of the internet.

What's the story behind your product?

notte.cc's answer:

Notte was founded by Andrea and Lucas, two ML researchers who met at EPFL in 2019 and have been building together ever since. After working across top research labs, they saw a clear gap: existing browser automation tools werenโ€™t built for LLMs. Notte is their response โ€” a framework that makes the web usable for agents through structured, semantic understanding. Itโ€™s designed to bridge research and real-world execution.
