EchooAI is an AI assistant for chatting, answering questions, solving problems, searching the web, and generating images. It offers access to multiple AI models, including Gemini 2.5, Qwen 3, LLaMA 4, and DeepSeek. The service also includes specialized AI reviews intended to identify missing assumptions or potential errors, with additional deterministic checks for Python syntax and simple arithmetic where applicable. EchooAI notes that its answers may be incorrect and recommends verifying important information. Users can ask questions or request help with tasks such as coding, mathematics, writing, research, and idea development. For web research, responses may include live sources. The site also provides a goal setting and tracking workspace: users can turn recommendations into measurable goals, record check ins, and ask the assistant to adjust plans based on their progress. User instructions can be added to guide the assistant’s behavior and are stored in the current browser using local storage. EchooAI offers a free starting tier and paid options that include unlimited messages and faster responses. The website does not specify particular device or software requirements.
