Features
EchoLive turns documents, feeds, and videos into high-quality audio — with a production studio (segment editing, SSML, exports) and a listening inbox (feed reader, organization, AI search) so you can listen, refine, and publish.

Your content stays private. Long jobs stay reliable. Access stays protected.
Each account has its own dedicated database. Your projects, feeds, and search index are isolated from every other user, not just filtered by permission.
Project text, AI comprehension data, and sensitive metadata are encrypted before storage. Your content is protected even at the infrastructure level.
Your text and audio are never logged or used for training. Client monitoring redacts sensitive fields by default. You own your content.
Background processing with progress tracking, automatic retries, and resumable sessions. Long scripts generate reliably without losing your place.
Modern authentication protects access across devices. Provider credentials are managed server-side and never exposed to the client.
Full data export and account deletion endpoints available. Your data is yours to keep or remove at any time.

Feed readers like Feedly and Inoreader are great at RSS aggregation. EchoLive is also a full feed reader, but it adds audio generation, AI-powered search, and a production studio on top.
If you use a feed reader today and wish it could also read content aloud, search semantically, or produce audio for sharing, EchoLive replaces the feed reader and adds everything else.
