Show HN: EchoStream – A Local AI Agent That Lives on Your iPhone

Hi HN,

I’ve been working on a project called EchoStream, and I’d love to share it with you.

As an AI startup founder, the first thing I do every morning is open Hacker News. I look for what other founders are building, check out new GitHub projects, and explore new products. But I started noticing that it was taking me the whole morning just to get through it all.

I began to wonder: could an AI help me read Hacker News more efficiently? Could it summarize everything so I can quickly scan through, and then dive deeper into what interests me? And more than that—could it store what I’ve seen so I can recall it later when it's relevant?

That’s the idea behind EchoStream.

EchoStream is a local AI agent that runs entirely on your iPhone. It includes a built-in thinking model to help you do more with less effort—privately and efficiently, without sending your data anywhere.

Some of its key features:

- Read and understand web pages using AI

- OCR for recognizing and processing text in images

- Automatically record, transcribe, and summarize audio

- An AI-powered news feed with fresh, relevant updates

- Memory search that connects new info with what you’ve seen before

It’s still early, but I’d really appreciate your feedback or thoughts. I built this for myself, and now I want to share it with all of you.

You can have a try here:https://apps.apple.com/us/app/echostream-mind-copilot/id6476... or to the homesite: https://www.echostream-ai.com/

Note: It works well on any iDevice with at least 4GB of RAM.
