I lost my uncle to violence in Nigeria a few years back. Before he died he sent me a voice note of encouragement, and I still have it, but it’s frozen. It can’t answer anything I ask it now.
EchoVault is my attempt to fix that. You do guided check-in sessions with an AI biographer that draws your actual stories out of you, and over time it builds an Echo that talks the way you talk and knows what you’d say. Most things in this space build an avatar from a few minutes of uploaded footage. This works the other way around, so the Echo can answer questions you never explicitly answered because it’s learned how you actually think.
Every response is grounded in something you really said, which means it won’t invent memories you never had.
Text is free forever with unlimited check-ins and no card. $12/mo adds your real cloned voice. There’s a $99.99 one-time setup for a lifelike video avatar that includes 3 months of live video, then $18/mo after that. The video tier is a live face to face conversation, not a rendered clip.
You name custodians up front. If a full year passes with no activity on your account, your Echo transfers to them automatically. No paperwork for a grieving family to figure out.
I shipped text, voice, and real-time video together in June 2025, which as far as I know made this the first digital legacy product where all three worked at once.

Built solo, nights only. Happy to answer anything. Will appreciate any feedback too, thanks

Briefcase is an iOS portfolio tracker I built solo, stocks, crypto, bonds, real estate, cash, all in one place. Just shipped an update today aimed squarely at a specific time-sink: checking on your portfolio and then manually digging through news to figure out why something moved.
The old flow, for me and probably you: open the app, see a red number, open a browser, search the ticker, skim three articles, still not sure which one actually explains it. That’s 10-15 minutes for something that should take 30 seconds.
What the update does instead:
Every holding shows its top headlines right on your dashboard, no separate search

Tap “Why did this move?” and the agent explains today’s price action with the actual news behind it, cited

A daily brief every morning ranks your biggest movers with the news attached, so you start the day already knowing what happened overnight instead of piecing it together

The part that actually saves time isn’t the AI part, it’s that you don’t have to leave the app or open five tabs. Everything that used to take a separate research detour is now inline.
It’s honest when it doesn’t know something too. Not every move has a clear cause, and the agent says so instead of inventing a reason, which matters if you’re going to trust it enough to skip own googling.

Briefcase is an iOS app I built solo for tracking your investments, stocks, crypto, bonds, real estate, cash, all in one place. Just shipped an update that replaced the AI feature’s old single-shot prompt with an actual agent, and wanted to share the before/after since this sub cares about that distinction.
What changed:
Old version: prompt template, no memory of your actual holdings, no way to verify what it said

New version: agent with tool access, pulls real market data + news per holding, and shows its actual tool calls (source, ticker, query) instead of just a confident-sounding answer

Proof it’s not running on stale training data: I asked it to break down today’s moves across a few holdings, and it correctly reasoned through the SpaceX-Cursor acquisition’s effect on SPCX, an event from just a few weeks ago. Most models would either not know about it or hallucinate something plausible-sounding instead.
New features on top of that:
Daily Brief: morning digest of your biggest movers with cited news

Headlines on every holding, right on your dashboard and on each asset’s detail page

“Why did this move?” — tap any holding, agent explains today’s price action with sources

The fun part was making it degrade gracefully. Not every mover has news behind it, so the agent has to say “no specific news explains this” instead of making something up. That honesty was harder to get right than the tool-calling itself. AppStore: https://apps.apple.com/us/app/briefcaseapp-8782dc/id6758148658

Been building Briefcase (iOS portfolio tracker) solo, and just shipped the update I’ve been wanting to build since v1: the AI feature finally has tools instead of just a prompt template. Briefcase is an iOS app built for tracking your investments, stocks, crypto, bonds, real estate, cash, all in one place

What changed:

**•** Old version: single-shot prompt, no memory of your actual holdings, no way to verify what it said

**•** “Why did this move?” - tap any holding, agent explains today’s price action with sources

I will appreciate any feedback or downloads and yes I will update the AppStore screenshots soon to showcase the new news features. AppStore: https://apps.apple.com/us/app/briefcaseapp-8782dc/id6758148658

I have just shipped version 1.03 of Prelude therapy prep. For context, it’s an Apple Intelligence powered tool that helps users prepare for therapy through a voice session that surfaces the thoughts most pertinent to share in therapy. With the feedback I got from my initial post I went and did a broad sweep of bugs and improved most of the features. The worst of the bugs was a broken voice prefetch system I thought was working, I removed it completely and replaced it with clear instructions on how to download natural voice(the app automatically detects it). The agent was also cutting people off when they made short pauses, I increased the silence threshold to 1300ms making it less likely for the agent to interrupt incomplete user entries. I also worked on the brief quality, it introduced a bit of latency with brief generation I will hopefully address that in the next update. The next update will be built to support ios27 and I will be transitioning the app to use the Private cloud compute for better model quality. Also the increased context window would let me leverage prompts better. Prelude remains free, but I will be adding a one time download fee once I cross 500 users, about half way there. App Store: https://apps.apple.com/us/app/prelude-therapy-prep/id6761587576

If you downloaded Prelude recently and noticed your therapy prep sessions getting cut off early, that was a real bug and not your device. The iOS 26.4 update changed how the foundation models behave on-device and it was tearing down sessions before they could complete. Basically unusable.

I shipped v1.0.2 this week with the fix. Sessions run to completion now and the brief generation works properly again.

For context, Prelude runs fully on-device with no backend, no cloud, no third-party APIs. Everything stays local. That’s the whole point of the app. So when the foundation model behavior shifted in 26.4, there was no server-side patch I could push. Had to ship a proper update.

If you tried it and gave up, worth giving it another shot. And if you’re on auto-updates you probably already have it. The next update coming in a few days will have barge-in support.

I know some may find this dystopian, but this was literally inspired by black mirror episodes. I created a digital clone of myself and embedded it with my memories and personalities also gave it my voice and physical likeness so that it can video call my relatives and friends when I’m gone. I’ve been met with a lot of controversy but since this idea came from black mirror, I decided to share it here. Would you clone yourself BM style or am I crazy? The clone was built on echovault.me

I was wasting sessions. Showing up with nothing organized, blanking for 45 minutes, then remembering everything I wanted to say on the drive home.
Prelude fixes that. A voice agent talks with you before each session to surface what’s on your mind. Then it generates a structured brief you and your therapist work through together. My therapist said sessions noticeably improved once we started using the briefs.
Fully offline. Nothing leaves your phone. Free forever, no ads, no in-app purchases. Built it as a charity project for the mental health community.

A few of you asked what this actually looks like in practice.
This is my answer.
What you’re watching is not me. It’s an AI echo trained on my voice, my memories, and my personality, having a real-time video conversation. This is the technology I was describing. Not a concept. Not a render. A working demonstration.
We are genuinely at the point where the mind does not have to end when the body does. That sentence used to be philosophy. Now it’s just an engineering problem that a small number of people are actively solving.
The reactions I’ve been getting mirror what this community said. Some people find it fascinating. Some find it deeply unsettling. Both reactions make sense to me.
Where do you land after seeing it?
