Show HN: Echologue – the private AI voice journal I built for myself

Echologue is a private AI voice journal available on iPhone and Android, designed for local-first operation. It allows users to export or wipe their data anytime, offering local JSON/CSV backups and the option to move memories to other AI tools. No account is required, ensuring no server archive to delete. Echologue focuses on private capture, structured recall, and answers grounded in the user's own history, distinguishing itself from typical write-only journals or chat apps that flatten conversations.
