Echo is a voice and text note-taking application that integrates AI technology to help users organize and refine their thoughts. Utilizing the GPT-4o large language model for transcription, recall, and insight generation, Echo accurately transcribes users' voice input and provides meaningful feedback based on past ideas, making the journaling experience more interactive and engaging. The product prioritizes privacy and security with encrypted notes, does not view user data, nor use it to train AI, adhering to industry best practices for data protection. Echo is currently in a free testing phase, with plans to introduce advanced features in the future.
