What Is Open Source AI? Transparency in AI Tools
Open source AI refers to AI software whose source code is publicly available under a license that allows inspection, modification, and redistribution. This includes open-weights models (like Llama, Mistral) and tools released under licenses such as MIT or GPL. Some apps publish source on GitHub for transparency without granting full open-source rights.
Explanation
In AI, "open source" has two dimensions:
1. Open source models: AI models whose weights and training code are publicly released. Llama (Meta), Mistral, Phi (Microsoft), and Gemma (Google) are examples. Anyone can download and run these models.
2. Open source tools: Applications built on AI that publish their source code. Users can verify exactly what the tool does with their data, building trust through transparency.
Open source matters especially for AI tools that handle sensitive text. With closed-source tools, you trust the company's claims about privacy. With open source, anyone can verify the code does what it promises.
How Echoo Helps
Echoo publishes its source on GitHub so you can review how it handles text and API keys. Echoo is free to use and proprietary. Combined with local LLMs, you can keep sensitive text entirely on your Mac.

Local LLM
A local LLM (Large Language Model) is an AI model that runs entirely on your own computer instead of in the cloud. Tools like Ollama, LocalAI, and LiteLLM make it easy to run models locally on Mac.
BYOK (Bring Your Own Key)
BYOK (Bring Your Own Key) is a model where an AI tool lets you use your own API key from an AI provider rather than routing your data through the tool's servers. This gives you direct control over privacy, costs, and model selection.
Ollama
Ollama is an open-source tool that makes it easy to run large language models (LLMs) locally on your computer. It handles model downloading, optimization, and serving through a simple command-line interface and local API.
