-# Introduction
+# W&B Weave
 
-**Weave** is a lightweight toolkit for tracking and evaluating LLM applications, built by Weights & Biases.
+Weights & Biases (W&B) Weave is a framework for tracking, experimenting with, evaluating, deploying, and improving LLM-based applications. Designed for flexibility and scalability, Weave supports every stage of your LLM application development workflow:
 
-Our goal is to bring rigor, best-practices, and composability to the inherently experimental process of developing AI applications, without introducing cognitive overhead.
+- **Tracing & Monitoring**: [Track your application from input to output](./guides/tracking/) to debug and analyze production systems.
+- **Systematic Iteration**: Refine and iterate on [prompts](./guides/core-types/prompts.md), [datasets](./guides/core-types/datasets.md), and [models](./guides/core-types/models.md).
+- **Experimentation**: Experiment with different models and prompts in the [LLM Playground](./guides/tools/playground.md). 
+- **Evaluation**: Use [pre-built scorers](./guides/evaluation/scorers#predefined-scorers), [object comparison](./guides/tools/comparison.md), and LLM  tools to systematically assess and enhance application performance.
+- **Guardrails**: Protect your application with [pre- and post-safeguards](./guides/evaluation/guardrails_and_monitors.md) for content moderation, prompt safety, and more.
 
-**[Get started](/quickstart)** by decorating Python functions with `@weave.op()`.
+Integrate Weave with your existing development stack via the:
+- [Python SDK](./reference/python-sdk/weave/index.md)
+- [TypeScript SDK](./reference/typescript-sdk/weave/README.md)
+- [Service API](./reference/service-api/call-start-call-start-post)
 
-![Weave Hero](../static/img/weave-hero.png)
+Weave supports [numerous LLM providers, local models, frameworks, and third-party services](./guides/integrations/index.md).

+Are you new to Weave? Set up and start using Weave with the [Python quickstart](/quickstart) or [TypeScript quickstart](./reference/generated_typescript_docs/intro-notebook.md).
 
-- Log and debug language model inputs, outputs, and traces
-- Build rigorous, apples-to-apples evaluations for language model use cases
-- Organize all the information generated across the LLM workflow, from experimentation to evaluations to production
