Most second brain apps stop at storage. You capture a note, tag it, link it, and hope you find it again someday. NeverWrite is built around the idea that your second brain should actually help you think, not just hold your thoughts. It's a local-first desktop app for macOS and Windows where your notes are plain Markdown files on your machine. No cloud sync, no account required, no telemetry. Your vault is yours.

The part I'm most excited about is the AI layer. NeverWrite supports agents powered by Claude, Codex, Gemini and Kilo, that work directly inside your vault. You can ask an agent to help you synthesize notes on a topic, find connections you missed, or draft a new note from your existing material. The key thing is that agents propose edits and you review them before anything changes, it has inline review hunks like modern code editors. The AI helps you process and connect your knowledge; it never rewrites your vault behind your back. That felt like the only honest way to build this.

If you've been frustrated by second brain tools that are great at capture but useless at synthesis, or by AI tools that feel like a black box you can't trust, NeverWrite is trying to solve both at once. Happy to answer any questions about how the agent review flow works or anything else.

Also, is open source ;)

Have fun with your vaults!

Out of sight, out of mind is a cliché. For me it's a lived thing.

I have a friend who's really well-connected in education. Another who knows everyone in the startup space. A cousin who went through something hard last year. And I... just don't think about any of them until something external forces the thought.

It's not that I don't care. I care a lot. It's that my brain doesn't passively maintain people. They go quiet and they disappear, until a WhatsApp notification or a random memory brings them back.

I started looking for something that could help. Not a CRM, I'm not managing relationships like a sales pipeline. Something more like a memory extension. "Hold onto things about people so I can actually show up for them." I couldn't find it.

Something like a Telegram bot. You voice-note into it after a conversation, "just got off a call with Neha, she's going through a job transition, mentioned she wants to get into product", and it stores that. When you're like "who in my life knows about product roles?" it surfaces Neha.

I want to understand - has anyone else dealt with this specific thing? And if so, what have you tried?

Did you find any app that actually helps with this? A notes system? A habit?

Would love to know what's worked (or what's failed) for others.

(Open Source) I built a second brain app where AI agents help you think — but you review every change before it happens

Anyone else constantly forget people exist - not because you don't care, but because your brain just... drops them?
