DocChat vs. Custom Assistant Platforms
Custom assistant platforms let you prompt a model with your knowledge. Let's compare that with a purpose-built RAG chatbot.
There's a whole category of platforms that prompt a large model with your uploaded files. They're powerful, but they leave the retrieval engineering to you. DocChat specializes in it.
DocChat vs. custom assistant platforms
| DocChat | Assistant platforms | |
|---|---|---|
| Automatic retrieval (RAG) | Built-in chunking + search | You configure the pipeline |
| Source citations | Default on | Optional / manual |
| Chunking quality | Tuned for grounding | Up to you |
| Widget + embed | Drop-in widget | Varies by platform |
| Setup time | Minutes | Hours of configuration |
When each makes sense
Assistant platforms are flexible and worth it for complex, custom reasoning chains. But if your core need is simple — turn your documents into a chatbot people can actually trust — a purpose-built RAG tool removes the configuration work and gets you a cited, grounded answer out of the box.
