Cypher

Cypher is a free AI assistant that brings together web search, file upload, and multi-model intelligence in one clean, private interface.

Unlike most AI chatbots, Cypher doesn't just chat — it works with your data. You can upload PDFs, CSV files, TXT documents, JPG images, or PNG files and ask questions about their content. Turn on web search for real-time answers to current questions.

Cypher gives you control over how it responds. Switch between five distinct personalities — Analyst (data-driven, logical), Writer (creative, descriptive), Coder (technical, code-focused), Friend (warm, conversational), or Default (balanced). Each personality changes the way the AI thinks and responds.

Behind the scenes, Cypher uses DeepSeek V4 Pro with a multi-model Fusion system that combines Gemini 3 Flash, Kimi K2.6, and DeepSeek V4 Pro in a panel. A judge model synthesizes the best answer from all three — giving you deeper, more accurate responses than a single model.

Everything runs in your browser. No login required. No data stored. No hidden costs. Just open the link and start chatting.

Built with Python, Flask, and the OpenRouter API, Cypher is designed for people who need real answers — not just chatbot fluff. Whether you're analyzing data, researching a topic, writing code, or just brainstorming, Cypher adapts to what you need.

The interface is clean and minimal. Switch between light and dark mode. Edit your messages to refine your questions. Rate responses to help the bot improve. All features are free and available immediately.

Cypher was created by a field operations professional who wanted to build tools that actually help people — not just another AI wrapper. It's the result of 11+ years of hands-on experience in the field, combined with a passion for building practical solutions.
