In this comprehensive guide, we compare Chatbase and Coveo across various parameters including features, pricing, performance, and customer support to help you make the best decision for your business needs.

Overview

Welcome to the comparison between Chatbase and Coveo!

Here are some unique insights on Chatbase:

Chatbase.co pitches itself as a no-code RAG tool—upload a few PDFs or web pages, and you’ve got a chatbot you can drop into Slack or your site. It’s a smooth on-ramp, but if you’re planning big integrations or expect serious traffic, you’ll want to dig past the splash screen. Simplicity is great, yet it can hide limits around deep customization and scaling.

Use this overview as a jumping-off point for a closer look at how Chatbase.co stacks up when projects grow more demanding.

And here's more information on Coveo:

Coveo adds RAG features to its enterprise search platform, folding AI answers into a unified index of SharePoint, Salesforce, file shares, and more. It’s powerful, especially with built-in permission filters, but setup targets larger orgs that already rely on Coveo for search.
