GDPR audits, data residency requirements, and the legal team's veto on US-hosted AI kill most off-the-shelf chat tools before the first sprint ends — Synaplan exists for exactly that wall.
Built by metadist data management GmbH and fully open-source, Synaplan runs on your own infrastructure, routes queries across OpenAI, Claude, Gemini, and local Ollama models, and tracks every token and its cost in one place. The RAG pipeline ingests PDFs, crawled web pages, and structured text, then surfaces answers through an embeddable chat widget — no custom coding required for the widget itself. Persistent memories let the model retain tone, preferences, and brand voice across sessions, which matters when your support agent needs to sound like the same person on every call. The visual DAG routing layer handles which model answers which query, though teams with complex conditional branching will find that abstraction has a ceiling.
Bottom line: Pick Synaplan when data sovereignty and audit logs are non-negotiable and your routing logic fits a drag-and-drop DAG; plan a different architecture when your branching conditions require programmatic control that the visual layer cannot express.

Synaplan is an open-source AI platform that lets teams connect multiple LLM providers — OpenAI, Claude, Gemini, and local models via Ollama — under a single interface with per-token cost tracking, GDPR-compliant data handling, and self-hosting as a first-class option. The core workflow runs in three layers: a RAG pipeline that ingests PDFs, crawled website URLs, and structured text; a DAG-based routing layer that maps incoming queries to the right model or knowledge source; and a chat widget that embeds on any website without requiring the site owner to write backend code. Audit logs accompany every interaction, satisfying compliance requirements that would otherwise block deployment in regulated European markets.
The memory system is the feature that separates Synaplan from a generic RAG wrapper. Rather than treating each session as stateless, Synaplan captures preferences, tone markers, and factual context as categorized memory nodes, visualized as a neural map that grows with use. The vendor states this enables the model to draft replies that sound consistent with a team’s established voice — useful for support agents or branded chat where session-to-session inconsistency would be noticeable.
Synaplan fits well for European companies that need a widget-based support interface backed by their own document corpus, and for developers who want to experiment with multi-model routing without handing data to a third-party SaaS. CRM and ERP integration for personalized widget answers is a paid-only feature. Where it breaks: the visual DAG routing layer, while accessible, is not a substitute for code when routing logic involves more than a few conditions. Teams that outgrow the canvas typically end up maintaining a parallel scripting layer, which raises the question of why they kept the visual layer at all. MCP server support is described in the v3.6.4 release notes, indicating the platform can act as an MCP host, though the docs describe this as basic at this stage.
