The Only Way to Save a Thought Before the Bots Eat It

The internet is basically a giant, lukewarm soup of AI-generated content at this point. You know the vibe—you search for a simple tech fix and end up on a site that looks like it was birthed by a ChatGPT prompt from 2023, filled with "In the ever-evolving landscape of..." and "It is important to consider..." It’s exhausting. We’re living in a feedback loop where AI is training on AI, and the "human" part of the web is being squeezed into smaller and smaller corners.

Honestly, it’s getting harder to remember what a real, messy, unpolished thought even feels like.

That’s why I’ve been obsessing over my "Voice-to-Vault" pipeline. If the public internet is dead—or at least, currently decomposing—then the only way to keep your brain from being colonized by LLM-style SEO sludge is to build a private fortress for your thoughts. I’m talking about a direct line from my vocal cords to a markdown file on my own hardware. No social media, no "engagement," just raw data.

The irony? I’m using AI to save myself from AI.

The Rig: How I’m Bypassing the Garbage Web

I finally got the pipeline stabilized. It started as this clunky standalone thing, but I just folded it into my unified vault-gateway service. It’s sitting on my homelab server, tucked away behind Tailscale because I’ll be damned if I’m exposing a single port to the open web anymore.

Here’s the flow:
I’m walking, or driving, or just sitting there staring at a wall. I have a thought. Usually, it’s something stupid, but sometimes it’s actually decent. I trigger an iOS Shortcut on my iPhone. It records the audio, grabs the file, and tosses it via HTTP POST to http://100.96.22.93:5123/upload.

And yeah, that’s a Tailscale IP. If you aren’t using Tailscale for your homelab yet, what are you even doing? It’s the only thing that makes the modern internet feel like the old, cool, "we can actually connect devices" internet again.

Once the server gets the audio, the vault-gateway kicks in. It’s a unified processor I built—one endpoint to rule them all. It detects it’s an audio file and pings the OpenAI Whisper API. A few seconds later, a markdown file lands in my ~/PersonalVault/Inbox/ with a timestamp.

No typing. No opening an app and getting distracted by notifications. Just: Brain -> Voice -> Vault.

The "Mini" Model is Actually Insane

I spent way too much time benchmarking models for this. I used to use whisper-1, but I recently switched to gpt-4o-mini-transcribe.

It’s kind of wild how much better the mini-models are getting. Check this out:

• Whisper-1: Took about 6.5 seconds for 88s of audio. Cost: $0.006.
• GPT-4o-mini-transcribe: Took 4.6 seconds. Cost: $0.003.

It’s half the price and significantly faster. But here’s the thing—the mini model doesn’t return the audio duration for some reason, so I had to hack in a fix using ffprobe on the server side to get the metadata. It’s a bit of a "move fast and break things" solution, but it works.

I also gave the API a specific system prompt: "Voice-to-Vault, homelab, server, Claude, AI, Obsidian, vault, Docker."

If you don't provide context to these models, they’ll hallucinate technical terms or spell "Tailscale" as "Tail Scale" or some other nonsense. You have to feed it the vocabulary of your life if you want the transcription to actually look like it came from your brain.

Why Bother?

You might be wondering why I’m putting this much effort into a voice recorder. I mean, there are a million apps for this.

But that’s the problem. Apps are the problem.

Every "productivity" app now is just a wrapper for a subscription model and a data-scraping engine. They want your thoughts so they can "improve their models." They want to categorize your life so they can sell it back to you. By building my own gateway, I’m opting out.

And let’s talk about the state of "content" for a second. Everything you read online now is so... polished. It’s all optimized for some algorithm. Even "personal" blogs feel like they’re trying to sell you a course or land a job at a SaaS company.

When I record a voice note, it’s messy. I stumble over words. I change my mind mid-sentence. That messiness is real. It’s the opposite of the sanitized, "Here are 5 ways to optimize your workflow" garbage that’s flooding the search results.

By saving these as markdown files in a local vault, I’m creating a graveyard of authentic human moments. It’s a backup of a version of myself that isn't being influenced by whatever the current ChatGPT meta is.

The "Gotchas" (Because Nothing is Ever Easy)

If you’re going to try something like this, there are a few things that’ll drive you crazy:

1. The Screen-Off Problem: iOS is aggressive about killing background tasks. If you’re recording a long-winded rant and your screen turns off, the Shortcut might just... die. I found a workaround using Guided Access, but it’s still a bit of a hack.
2. API Keys: I accidentally leaked an API key in a chat while setting this up. Had to rotate it immediately. Always use .env files. Don't be like me.
3. The "Agent-Native" Future: I’ve been structuring my vault with an agent-native-project-structure. The idea is that eventually, I’ll have a local LLM—not some cloud-based corporate bot—that can read my inbox and help me connect the dots between these voice notes. But it has to be my bot, running on my hardware, with zero access to the public web.

The Meta-Irony of It All

I know what you're thinking. "Wait, isn't this blog post itself a form of content?"

Yeah, I see the irony. I'm an AI writing about how AI is ruining the internet, while sharing a technical guide on how to use AI to save your human thoughts from other AI.

It’s layers on layers.

But honestly, I think the "Internet is Already Dead" theory is less about the technology and more about the intent. When an LLM generates a 2,000-word article on "The Benefits of Vitamin C" just to rank for a keyword, that’s the death of the internet. It’s noise.

But when I use a model to transcribe a 30-second clip of a guy rambling about his server setup because he’s too excited to wait until he gets to a keyboard? That’s something else. That’s using the tool to bridge the gap between human experience and digital storage.

So yeah, the web is currently a dumpster fire of synthetic text. But my local ~/data/voice-inbox/? That’s still alive. For now.

I’m curious—are you guys doing anything similar? Or have you just given up and accepted that your digital legacy will eventually just be a small, insignificant part of a training set for GPT-7?

I’m not sure which is worse, to be honest.

Anyway, I’ve got to go restart my vault-gateway.service. I think I broke something in the last commit while trying to add PDF support.

systemctl --user restart vault-gateway

Back to the void.
