# Why ProBot

> How ProBot compares to generic chatbot platforms: your key, your data, free and open source.

Most chatbot builders are closed, hosted-only SaaS: their model, their key, their pricing, your data on their servers. ProBot is the opposite - your key, your data, free and open source.

## Honest comparison

| What matters                       | ProBot | Generic platform |
| ---------------------------------- | :----: | :--------------: |
| Bring your own LLM key (no markup) |    ✅   |         ❌        |
| Free to use                        |    ✅   |         ❌        |
| Open source (MIT)                  |    ✅   |         ❌        |
| Self-hostable                      |    ✅   |         ❌        |
| Keys never logged                  |    ✅   |         ❌        |
| GDPR data export + deletion        |    ✅   |         ❌        |
| No telemetry / no ad tracking      |    ✅   |         ❌        |
| Embeddable widget                  |    ✅   |         ✅        |

*"Generic platform" reflects the common default of closed-source, hosted-only chatbot builders. The point is what ProBot guarantees by design.*

## The short version

* **Your key, no markup.** Use your own Claude / OpenAI / Gemini / Azure key. We never resell tokens.
* **Your data.** Conversations are logged anonymously; export or delete everything any time.
* **Open and auditable.** Read every line, fork it, self-host it.
