-## What is CodeRabbit?
+# Introduction
 
-> **CodeRabbit** is an AI-powered code reviewer that delivers context-aware feedback on pull requests within minutes, reducing the time and effort needed for manual code reviews. It provides a fresh perspective and catches issues that are often missed, enhancing the overall review quality.
+This page provides a conceptual introduction to CodeRabbit. For a hands-on tutorial, see [Quickstart](/getting-started/quickstart/).
 
-Developers can interact directly with the bot within the code, offering additional context, asking questions, or even having the bot generate code. Over time, **CodeRabbit** learns from user input and improves its suggestions.

-## Integration with GitHub, GitLab and Azure DevOps
+## Core features
 
-> **CodeRabbit** integrates with GitHub, GitLab and Azure DevOps repositories to deliver continuous and incremental reviews for each commit in a pull request (PR) or merge request (MR). Review feedback is automatically sent back to the PR/MR and can be committed directly.
+Core CodeRabbit features include the following:
 
-It works via a webhook, monitoring Pull Request (PR) and Merge Request (MR) events. A comprehensive review is performed when a PR or MR is created, and for
-incremental commits and comments addressed to the bot. The feedback is then sent directly back to the Pull Request or Merge Request.
+- Integrates rapidly with popular Git platforms and workflows.
+- Applies dozens of open-source, industry-standard code analyzers to every commit.
+- Implements code reviews as familiar pull-request comments.
+- Works with contributors through natural-language conversation in comments.
+- Learns and adapts to your team's code style and review preferences.
+- Provides an observability dashboard of code-contribution activity.
+- Practices strong privacy and security, with no retention of analyzed code.
+- Offers free use for public repositories, and flexible pricing for private codebases.

+## Seamless workflow integration
 
-## Data Privacy and Security
+CodeRabbit shares its reviews as comments attached to pull requests, using the same Git platform that your team already uses. Further commits in the same pull review prompt CodeRabbit to make further reviews, using the earlier reviews as context.
 
-> **CodeRabbit** does not use data collected from code reviews to train or influence its models. All queries to Large Language Models (LLMs) are ephemeral, with zero retention. No data is shared with third parties.
+Each time that it performs a code review, CodeRabbit runs the relevant code changes through [an array of industry-standard code linters, security analyzers, and other tools](/tools/). CodeRabbit synthesizes the output of these tools into its reviews, offering a high-level analysis that can suggest areas for further focus and improvement.
 
-- **Temporary Storage**: Code is temporarily stored in memory during the review process and deleted afterward.
-- **Stored Embeddings**: While the code itself isn’t stored, **CodeRabbit** stores embeddings based on chat conversations and workflow systems (Linear, Jira, GitHub/GitLab issues) to improve future reviews.
-- **Compliance**: All data is kept confidential, isolated by organization, and complies with **SOC2 Type II** and **GDPR** standards.
+Your team can have conversations with CodeRabbit about its reviews by replying to it with follow-up comments on pull requests, asking it questions or making observations about the review using natural language. CodeRabbit continues the conversation appropriately, offering further insights about the code changes, or adjusting its own review style based on feedback.
 
-### Opting Out
+### Customizable review preferences
 
-You can opt out of data storage at any time without affecting your access to **CodeRabbit**.
-:::warning
-However, opting out may reduce the level of personalized review feedback.
-:::
+As you interact with CodeRabbit through chat, it learns the review preferences of your team, and applies them to all future reviews on a given repository.
 
-## Try CodeRabbit Now
+For example, if CodeRabbit uses a linter to suggest that your pull request use four-space indentations, but your team uses a two-space indentation style, then you can reply to CodeRabbit's pull-request comment to tell it exactly that. CodeRabbit acknowledges your feedback and adjusts all of its subsequent reviews with that repository appropriately.

-:::tip
-For open source projects CodeRabbit Pro is **_FREE_**, forever.
+If you need to fine-tune CodeRabbit's behavior beyond this, then you can [add a CodeRabbit-specific configuration file](/getting-started/configure-coderabbit) to your repository, or use the CodeRabbit web UI to set further preferences. This file can include [path-based instructions](/guides/review-instructions) for how CodeRabbit should review different files within your codebase.
 
-- No credit card required
-- Unlimited public repositories
+No matter how you tune and customize CodeRabbit, its default settings make it useful out of the box, able to meaningfully review pull requests within minutes of its introduction to a repository.
