+## Why use PR-Agent?
+
+A reasonable question that can be asked is: `"Why use PR-Agent? What make it stand out from existing tools?"`
+
+Here are some of the reasons why:
+
+- We emphasize **real-life practical usage**. Each tool (review, improve, ask, ...) has a single GPT-4 call, no more. We feel that this is critical for realistic team usage - obtaining an answer quickly (~30 seconds) and affordably.
+- Our [PR Compression strategy](./PR_COMPRESSION.md)  is a core ability that enables to effectively tackle both short and long PRs.
+- Our JSON prompting strategy enables to have **modular, customizable tools**. For example, the '/review' tool categories can be controlled via the configuration file. Adding additional categories is easy and accessible.
+- We support **multiple git providers** (GitHub, Gitlab, Bitbucket), and multiple ways to use the tool (CLI, GitHub Action, Docker, ...).
+- We are open-source, and welcome contributions from the community.

 ## Roadmap
 
 - [ ] Support open-source models, as a replacement for OpenAI models. (Note - a minimal requirement for each open-source model is to have 8k+ context, and good support for generating JSON as an output)
