Echoes

Voice notes you can search.

[ THE PROBLEM ]

Voice notes are easy to record and almost impossible to use later. You end up scrubbing through audio trying to find the one thing you said last week.

Echoes was built for an audience of one: me. I wanted a place to talk through ideas on a walk, and I wanted to test how far I could push API calls and AI inside an app before betting a real product on those skills.

[ ABOUT ]

Ever record a voice note and then forget what you said? Or spend ten minutes scrubbing through audio to find that one thing?

Echoes transcribes your voice notes automatically. Talk, and it turns into text you can actually search later. You can also chat with your notes. Ask it to pull up what you said yesterday and it finds it.

There's an unfinished feature I still think about: a mind-map view that connects related notes. Record a note about the grocery store one Sunday, record a meal idea ten days later, and Echoes draws the line between them.

[ HOW IT WORKS ]
01

Record

Hit record and talk. Brain dump, meeting notes, random ideas in the shower. Whatever you need to capture.

02

Transcribe

Echoes uses AI to turn your voice into text. Fast, accurate, and happens automatically.

03

Search

Need to find something you said last week? Just search. No more scrubbing through audio.

[ KEY DECISIONS ]
01

Build it as a test bed, not a product

Echoes was where I learned to wire AI into an app: transcription, chat-with-your-notes, connecting related ideas. Those skills went straight into everything I shipped after it, including Ripple's entire AI pipeline.

02

Don't ship it

It would have been easy to polish Echoes and push it to the App Store like everything else. I didn't. It solves my problem, it taught me what it needed to teach me, and not every project earns a launch. Knowing which ones don't is the skill.

[ RESULTS ]
Never shipped, on purposeand still used daily by its only intended user. The AI patterns it proved out went into every product that came after.
