HoloChat Pro

Meet Holo Chat Pro — the universal AI chat app that connects to any OpenAI-compatible API, and puts 31+ real-world tools at your fingertips. This app does not provide any API service. You bring your own API key from your preferred AI provider, and you are responsible for its availability and usage. Holo Chat Pro simply connects you to the models you already have access to. Connect to OpenAI, or use OpenRouter to access Claude, Gemini, Grok, DeepSeek, Qwen, GLM, Groq, local LLMs, and hundreds more. No subscriptions to this app. You pay only for the models you use, at your provider's direct prices. Switch between models instantly — save multiple API profiles and jump from DeepSeek to Claude to Qwen with one tap. No need to reconfigure every time. Prompt caching support for compatible models can significantly reduce your token usage on long conversations — potentially cutting API costs by half or more on repeated context. Why Holo Chat Pro is different Most AI chat apps can only talk. Holo Chat Pro can act. Your AI searches the web, runs code, downloads files, reads and writes project files, sends emails, sets calendar events, checks your location, opens navigation, plays music, generates PDFs — 31+ tools in one conversation. Extend the AI with custom skills Tell the AI to write and run custom scripts on the fly — process data, generate html, svgs. If the 31+ built-in tools aren't enough, the AI creates what you need. True multimodal conversations Send images, record voice memos, attach video files. Receive image and audio replies. The AI sees and hears what you do, all in one thread. Beautiful message rendering Markdown formatting, LaTeX math formulas, Mermaid diagrams, syntax-highlighted code, and live previews of SVG and HTML — all rendered natively in your conversation. Tap any message for full-screen reading. Smart conversation management Color-coded tags for effortless organization. Filter, batch-select, bulk-tag, and auto-summarize with AI. Search titles and message content. Lock conversations with Face ID or Touch ID. Your conversations, your files Every chat is saved as an individual file on your device. Browse, copy, back up, edit, or transfer them through the Files app. No lock-in, no gatekeeping. Project-linked coding assistant Link a conversation to a local project folder. Your AI can read, write, search, and manage your project files. Home screen widgets Three widget sizes show your recent conversations with colors that match your app theme. Full desktop-grade WebUI Holo Chat Pro includes a powerful web interface that turns any browser on your network into a management console. Browse conversations, edit profiles, manage backups, organize projects, curate app whitelist, maintain system prompt templates, and upload music files. The built-in model browser lets you explore hundreds of OpenRouter models with smart filters for Tools, Reasoning, Structured Outputs, and Vision support — plus expiration warnings so you are never caught off guard by a deprecated model.
