<br>

**API2CHAT** is a lightweight (below 13KBs), purely client-side Graphical User Interface designed to interact with any OpenAI-compatible LLM endpoint. It bypasses the need for bloated backends, databases, or subscriptions, allowing you to plug in your own API keys securely. 

**NEW v2 release!** Added the free OpenRouter models by default (https://openrouter.ai/openrouter/free), so you can simply paste your OpenRouter API key. **Important!** OpenRouter's free tier for free models typically allows 200 daily queries. If you purchase at least 10 credits (about $10), your daily limit increases to 1000 free model requests per day :)

## 💡 [SEE LIVE DEMO](https://pacifaist.github.io/API2CHAT/)

## 🚀 Key Features

* **🛡️ 100% Zero-Knowledge Security:** No data, API keys, or chat logs are ever transmitted to or stored on a centralized server. The app runs entirely in your browser's volatile memory. Refreshing or flushing the session destroys the keys locally.
* **🔌 Maximum Compatibility:** Natively supports OpenAI, Google (Gemini via OpenAI Shim), DeepSeek, and OpenRouter. Features a "Custom" mode to connect to any local (e.g., LM Studio, Ollama) or remote provider using the OpenAI standard.
* **📎 Local File Context:**  Files are read locally by your browser and injected into the LLM prompt without requiring an upload server. Even when you can attach a file to it (e.g., a PDF) it is not stored anywhere.
* **💻 Host Anywhere:** Because there is no PHP, Python, or Node.js required, you can host API2CHAT on GitHub Pages, S3 buckets, cheap shared hosting (e.g., Namecheap), or simply double-click `index.html` on your desktop (Windows, Linux, iOS, Android, rpi-related...).
* **🎨 Hacker Aesthetic:** A sleek, minimal, dark-mode UI with full Markdown rendering and code syntax highlighting.

### 📎 Local File Reading (Zero-Upload)
API2CHAT can natively read local files and inject them directly into your LLM prompt. **Files are never uploaded to a server**. Your browser reads the text locally and sends it straight to the API provider. 

## 🛠️ Deployment Locally or Starting from a Cheap Shared Webhosting

1. Clone or download this repository or its [ZIP release](https://github.com/PacifAIst/API2CHAT/releases/download/API2CHAT_v2/API2CHAT-API2CHAT_v2.0.0.zip) (less than 13KBs).
2. **Unzip the contents** to your device or any hosting provider _(from low-end Namecheap, Hostgator, etc... will work!)._
3. Double-click `index.html` to open it **in any browser and OS** _(requires no: PHP, Python, Node.js... nothing!)._
4. Select provider, paste your API key, and start chatting. You can **copy/paste text or upload a file** to ask the LLM.
5. _(Optionally)_ To make sure all data was erased click **"Flush session"**, or if you wish to start a new clean chat.
