Your AI answers from your documents

Upload PDFs, Word files, or crawl entire websites. RAG grounds every answer in your own data — so replies are accurate, not generic.

Every prompt, response, model, and token count is logged with a timestamp. Export for compliance or feed your existing SIEM.

Reach

Your data, your rules

Self-host on your own infrastructure or use our EU cloud. Full data sovereignty, always.

Memories

AI Memories & RAG — structured and actually used

Capture preferences, tone, and facts as categorized memories. The neural view shows how they connect to your categories so the model can draft replies, automate email, and sound like you.

You open the web app — you describe tone and context in your own words. Each save adds a memory; the neural map grows category by category beside the conversation.

Frequently asked questions

Everything you need to know about Synaplan — from setup to GDPR compliance.

Synaplan is an open-source AI platform built on PHP 8.3+. It lets you connect multiple AI models (OpenAI, Anthropic, Groq, Gemini, Ollama), embed a chat widget on any website, search your documents with RAG (retrieval-augmented generation), and extend functionality with business-specific plugins — all in one self-hosted platform.

Yes. Unlike ChatGPT, Synaplan runs on your own infrastructure, supports multiple AI models simultaneously, is fully open source, and keeps all data within your control. You are not dependent on a single provider and can switch models at any time.

Absolutely. Synaplan can be self-hosted entirely within Germany or the EU — your data never leaves your servers. With local models via Ollama, no external API calls are made at all. This makes Synaplan one of the few AI platforms that can be operated in full GDPR compliance.

You embed a small JavaScript snippet into your website — just like a Google Analytics or live chat script. The widget connects to your Synaplan instance, uses your custom knowledge base (uploaded documents, FAQs, etc.), and can be styled to match your brand. Setup takes less than 10 minutes.

Synaplan supports OpenAI (GPT-5.5, GPT-5.5 Pro), Anthropic (Claude Opus 4.8), Google Gemini, Groq (ultra-fast inference), and Ollama for local self-hosted models. You can assign different models to different use cases or let the platform route automatically.

Yes — that is one of Synaplan's core strengths. A single `docker compose up -d` is all it takes. The standard setup (~9 GB) includes local AI via Ollama; the minimal setup (~5 GB) works with cloud APIs only (Groq, OpenAI). Runs on any standard Linux server.

Plugins are company-specific AI extensions that connect Synaplan to your existing business processes. Examples include SortX (AI-powered file management), marketing automation, and document workflows. You can use existing plugins or commission a custom plugin tailored to your company.

Synaplan is used by SMBs and enterprises across industries including hospitality, trades & crafts, healthcare, and technology. Website operators use the chat widget for customer service, while larger organizations use the full platform for internal knowledge management, document processing, WhatsApp integration, and email automation.
