AppFlowy is an open-source (AGPL-3.0) collaborative workspace and Notion alternative built in Flutter/Rust, available as desktop and mobile apps plus a self-hostable backend. Its AI features (writing assistance, summarization, chat over your docs, generation) are BYOK in several ways: AppFlowy Local AI lets you point the desktop app at your own local models installed through Ollama (gemma3, qwen3, Llama 3.1, DeepSeek R1, Phi4, etc.) so data stays fully on-device, and this was made free for everyone. Beyond local models, self-hosted and cloud setups let you supply your own OpenAI API key, switch to Anthropic Claude in AI Settings, or configure a custom OpenAI-compatible base URL with an optional API key, enabling any OpenAI-compatible provider.

How this tool was scored

Key handling 90/100 (where your key rests and who sees it, comparable across any licence) and verifiability 70/100 (how much of that BYOAIK could confirm, lower for closed source). Neither contains a popularity signal.

  • Key Safety 23/25: The key is held on your own device.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under AGPL-3.0, so anyone can check how the key is handled.
  • Privacy 14/15: Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control.
  • Maintenance 8/10: Commits within the last six months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

How your API key is handled

Your API key is stored locally on your device. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Open settings, paste your provider API key, choose a model, and start. The key stays on your device.
