Question 1

What is Open WebUI and how is it a self-hosted alternative to Notion AI?

Accepted Answer

Open WebUI is a self-hosted web interface for any Large Language Model. Unlike Notion AI (which is a feature bolted onto Notion's core product), Open WebUI is built from the ground up as an AI-first platform. Notion AI searches only Notion docs and sends prompts to external LLM providers (30-day data retention). Open WebUI can run entirely offline, search across 45+ knowledge sources (Notion, GitHub, Slack, Confluence, Google Drive), and keep all data on your infrastructure. You also choose which LLM to use: ChatGPT, Claude, Llama 3 locally, Mistral, or any OpenAI-compatible API.

Question 2

How much does Open WebUI cost compared to Notion AI?

Accepted Answer

Notion AI is included in Notion Business (€19.50/user/month). A 10-person team costs €195/month. Add Custom Agents (automated workflows) and you pay an additional €10 per 1,000 monthly credits. Easily €300+/month for modest automation. Open WebUI managed hosting: €30/month flat rate, unlimited users, unlimited usage, no overages. That's 86% savings. Self-hosted Open WebUI is completely free—only your infrastructure costs apply (which often fits in free or low-cost tiers on AWS, Azure, or your datacenter).

Question 3

Can I migrate my data from Notion AI to Open WebUI for free?

Accepted Answer

Yes. Use oikb (Open WebUI's knowledge sync tool) to import documents from Notion, GitHub, Slack, Confluence, Google Drive, and 40+ other sources. The process is straightforward: authorize the source, select documents, and oikb syncs them into Open WebUI's vector database for instant RAG search. You can also manually export Notion docs as Markdown or PDF and upload them directly to Open WebUI. The hardest part is deciding which documents to migrate—we recommend starting with your most-accessed knowledge bases and scaling up.

Question 4

Is Open WebUI GDPR compliant?

Accepted Answer

Yes. Open WebUI is fully GDPR-compliant by default. When self-hosted, all data stays on your infrastructure—no external transfers, no third-party processors, no data retention issues. You own everything. If using Opsily managed hosting, we offer EU-based data residency, and all data stays within the EU region you choose. Notion AI, by contrast, requires LLM provider access. Even Notion Business plans retain data for 30 days with third-party LLM providers. Only Notion Enterprise offers zero-retention (at custom, higher pricing). If GDPR compliance is critical, Open WebUI is simpler and more straightforward.

Question 5

What LLM models can I use with Open WebUI?

Accepted Answer

Open WebUI supports 50+ LLM providers and models: OpenAI (GPT-4, GPT-4o), Anthropic Claude, Mistral, Groq, Google Gemini, Ollama (run Llama 3, Mistral locally), LMStudio, vLLM, and any OpenAI-compatible API. You can even mix and match—use Claude for analysis today, switch to a local Llama 3 tomorrow, then try Groq next week. No re-architecture. No data migration. No vendor lock-in. This flexibility is why teams choose Open WebUI: you're not locked into Notion's LLM partners.

Question 6

Does Open WebUI support team collaboration and GDPR compliance?

Accepted Answer

Yes. Open WebUI includes full team collaboration: real-time shared spaces, channels, threads, and reactions. Permission management via role-based access control (RBAC) and user groups lets you grant granular access per document or workspace. SSO integration (Okta, Azure AD, Google Workspace) makes provisioning quick. Audit logs track every user action—critical for compliance. LDAP and Active Directory support mean it integrates with your existing identity system. All these features come standard in every plan, and data residency is fully under your control.

Question 7

How do I set up Open WebUI for my team?

Accepted Answer

Three options: (1) Self-host for free using Docker or Kubernetes—deploy in minutes on AWS, Azure, GCP, or on-prem. (2) Use Opsily managed hosting—set up via web UI, no server knowledge required. (3) Use a managed hosting partner like Elestio or Agntable—they handle infrastructure, you handle the rest. All three approaches are simple. Self-hosted is free but requires you to manage updates and backups. Opsily managed includes automatic updates, SSL, backups, and monitoring. Pick the option that matches your team's comfort level.

Question 8

What happens to my data with Open WebUI vs. Notion AI?

Accepted Answer

With Notion AI, your prompts go to external LLM providers, which retain them for 30 days (Notion's data retention policy). Your knowledge base stays in Notion's cloud. You don't own the infrastructure. With self-hosted Open WebUI, all data stays on your servers—zero external calls unless you configure an external LLM API. Your knowledge base is yours. You control backups, retention, and access. With Opsily managed hosting, data stays in the region you choose (EU or US), is encrypted in transit and at rest, and never touches third parties unless you explicitly connect an LLM provider. You always own your data.
