DoxyChat vs Chatbase 2026: Same RAG, Very Different Data Sovereignty

If you’re comparing DoxyChat and Chatbase, you’ve already made a smart decision: you want a chatbot that answers only from your own documents, with no hallucinations beyond your knowledge base. Both platforms use Retrieval-Augmented Generation (RAG) to do exactly that.

But for businesses operating under European data protection law, the technical similarity between these two tools hides a regulatory gap that could put your compliance at risk. Here’s what you need to know before choosing.

How RAG Works in Both Tools

RAG (Retrieval-Augmented Generation) is the architecture that makes document-trained chatbots accurate. Rather than drawing on a language model’s general memory, the chatbot first retrieves the most relevant chunks from your uploaded content, then generates an answer strictly grounded in those sources.

Both DoxyChat and Chatbase implement RAG. Upload your PDFs, connect your website, and your chatbot will answer from your content — not from the internet or the model’s training data.

The difference lies in what happens beneath the surface: which LLM processes your queries, and where your data is stored.

Chatbase runs on OpenAI models (GPT-3.5 and GPT-4) and operates exclusively on US-based infrastructure. Every user message and every document you upload transits through American servers — twice: once to Chatbase’s systems, then again to OpenAI’s API.

DoxyChat runs on Mistral, a European LLM developed in Paris and hosted on Scaleway’s French infrastructure. Your data never leaves France. There is no cross-Atlantic data flow, no OpenAI dependency, and no CLOUD Act exposure.

Feature-by-Feature Comparison

The GDPR Reality Behind Chatbase’s Compliance Badge

In 2024, Chatbase achieved formal GDPR compliance: DPA available, AES-256 encryption, SOC 2 Type II certified. The security page looks reassuring.

But there’s a critical distinction that many buyers miss: GDPR compliance via Standard Contractual Clauses (SCCs) is not the same as EU data residency.

Chatbase’s own privacy policy states clearly: “Personal data is stored on servers and cloud-based services located in the United States.” No EU hosting region exists. No European data center option is available.

This creates two specific risks for European businesses:

CLOUD Act exposure. Under the Clarifying Lawful Overseas Use of Data Act, US authorities can compel access to data held on US-based infrastructure, regardless of where the data subject is located. SCCs provide contractual protections but cannot override this statute.

OpenAI in the data chain. Every user message processed by Chatbase is sent to OpenAI’s API — an additional US entity in your data pipeline. For businesses in healthcare, finance, legal services, or public administration, where data flows must be explicitly controlled and documented, this dual US exposure is often a disqualifying factor.

DoxyChat eliminates these issues by design. Data stays in France, on Mistral-powered Scaleway infrastructure. No Standard Contractual Clauses are required because the data never moves outside the EU in the first place.

Pricing: The Full Picture

At the mid-tier, the gap is significant. DoxyChat Growth delivers 5 chatbots and 500 documents for €39. Chatbase Standard gives you 2 agents and 40 MB of data for approximately $49.

The most surprising cost in Chatbase’s model is the white label fee. Removing the “Powered by Chatbase” badge from your widget — something most professional deployments require — costs an extra $199 per month on top of your base plan. A $49 Standard plan becomes a $248/month commitment just for a brandless widget.

DoxyChat includes full white-label customization (colors, logo, widget appearance) on every plan, including the free Discovery tier.

What Chatbase Does Well — And Where It Falls Short

Chatbase has strong name recognition in the English-speaking market and a clean setup experience. If you’re based outside the EU, processing non-sensitive data, and only need one or two chatbots for internal testing or a side project, it’s a capable tool.

However, Chatbase is also repositioning itself. Their homepage now leads with “AI agents built to elevate customer experiences” — a pivot toward agentic AI workflows that moves them away from their original focus on document-based RAG chatbots. For businesses that need a reliable, focused RAG solution that trains on documents and stays on topic, this strategic drift is worth monitoring.

DoxyChat, by contrast, is purpose-built and stays focused: upload your content, get a chatbot that answers only from it, deploy it anywhere with one line of JavaScript.

Which Platform Fits Your Situation?

Choose Chatbase if:

• You’re outside the EU and data residency is not a compliance requirement
• You need a quick single-agent setup for a personal or small-scale project
• You’re comfortable with US infrastructure and OpenAI’s data processing terms

Choose DoxyChat if:

• You process data subject to GDPR and need genuine EU hosting — not just SCCs
• You work in a regulated sector: finance, healthcare, legal, education, or public services
• You need multiple chatbots (agencies, multi-site businesses, internal + external deployment)
• You want white-label branding included without a separate fee
• You need to keep your chatbot current with live web content or RSS feeds
• You want a free plan without a countdown timer

Conclusion

Both DoxyChat and Chatbase let you build a RAG chatbot from your documents. The user experience of setting one up is similar. The technical architecture is comparable.

But for European businesses — and especially those in regulated industries — the infrastructure choice is not a technical preference. It’s a compliance decision.

Chatbase routes your data through US servers and OpenAI’s US-based API. DoxyChat keeps everything in France, on Mistral-powered infrastructure with no transatlantic data flows, no Cloud Act exposure, and GDPR compliance built in by default rather than bolted on.

If you want to test the difference for yourself, DoxyChat’s Discovery plan is free forever — no credit card required, no 14-day deadline, no badge fees.
