Everything you need to get the most out of Holo Chat Pro.
Holo Chat Pro lets you chat with any AI model through OpenAI-compatible APIs, with 31+ built-in tools at your command.
You'll need an API key from an OpenAI-compatible provider. Popular options:
Go to Settings → API Key and paste your key. It's stored securely in iOS Keychain — never shared or uploaded anywhere.
That's it! Choose a model, type or speak your message, and your AI can use 31+ tools to help you get things done.
Yes. Holo Chat Pro does not provide API services. You bring your own key and connect directly to your chosen provider. You are responsible for its availability and usage.
No. The app is free to download. You only pay your provider directly for the tokens you use. No markups, no hidden fees.
Save multiple API profiles and switch with one tap. Keep different keys and model preferences organized.
Everything stays on your device. Chats are saved as individual files you can browse, back up, or transfer through the Files app. No data is sent to any server except your chosen API provider.
Any model available through your API provider. With OpenRouter you get 200+ models: GPT-4o, Claude 3.5/3.7, Gemini 2.0, DeepSeek V3/R1, Qwen, GLM, Groq, Mistral, Llama 3, and more.
Some providers (like OpenRouter with Claude) support prompt caching, reusing repeated context from previous turns. This can cut your API costs by 50% or more on long conversations.
Yes. Link a conversation to a local project folder. The AI can read, write, search, and manage your project files — like a coding assistant built into your chat.
Deleted conversations go to the Recycle Bin and stay there for 30 days. You can recover or permanently delete them at any time.
