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!

As a freelancer and lead software engineer, Obsidian is my main tool for everything: note-taking, project management, client docs, and technical research.

What started as a note-taking experiment turned into a full second brain. I even built a small CRM inside it using templates and bases to manage clients and projects.

But the real game changer? MCP with Claude Code and Claude Desktop. Having AI that can actually read, write, and navigate my vault changed how I capture and organize information entirely. It helps with note-taking, research, drafting docs, basically anything that used to slow me down.

I haven’t started saving my chat history into the vault yet, but I’m seriously thinking about it. Would love to hear from anyone who does that already.

Every cluster in this graph is a different area of my work and life. Still a lot of isolated nodes but watching the connections grow over time is genuinely satisfying.

Anyone else using Obsidian + MCP as their main OS for work?

I have had a hard time collecting stuff and finding it later. Whether it be designs, articles, code snippets, or just random inspiration, it always ended up scattered across bookmarks and forgotten apps.

To fix this, I built a free extension that uses a quick shortcut to snip exactly what you see directly into one Notion database. It is as quick as a regular bookmark, but keeps everything visually accessible from anywhere.

Hey there 👋

I built a Second Brain system in Notion to manage projects, notes, goals, and knowledge in one place without it turning into a messy note dump.

Here’s what it actually includes:

• Life areas (personal, health, work, finance, growth)
• Projects linked to goals and areas
• Tasks connected to projects (not floating todo)
• Notebook, notes, topics, and resources organized
• Accountability partner that shows your report

Productivity framework used:

• PARA-based structure (Projects, Areas, Resources, Archive)
• Get Things Done productivity framework
• Eisenhower matrix

How it helps in real life:

Before:
• Notes everywhere
• Tasks disconnected from goals
• Hard to remember what mattered

After:
• Everything has a place
• Projects and goals stay visible
• Easier to think, plan, and execute

I realized something kind of frustrating.
I save a lot of tings because I think they might matter later.

-a good article.
-a YouTube video.
-a PDF document.
-a quote.
-a note.
-a screenshot.
-a random idea.
-a post that explains something better than I could.

But after a while, all of it becomes scattered across different apps. Bookmarks become a graveyard. Notes become messy. Screenshots get buried. Saved posts disappear. And the things that once felt important slowly became impossible to find again. That bothered us.Because we don't just consume content for entertainment. A lot of us consume to learn, build, think, research, create, and understand the world better.

So why does most of what we save become useless?

That's the problem we're trying to solve with Recallr.

We're building an iOS-native AI second brain that turns your saved links, videos, PDFs, notes, and ideas into a private memory layer. The goal is not just storage. Not just summaries.Not just another notes app.

The goal is to build a second brain that adapts to what you care about.

As you save more, Recallr starts building a knowledge map around your content, a visual network of ideas, sources, and connections. Instead of everything sitting in isolated folders, your saved content becomes linked together through meaning. You can see how one idea connects to another, ask questions across everything you’ve saved, and rediscover things you forgot you even had. Instead of your saved content becoming digital clutter, it becomes something you can actually think with.

We're still early, and the waitlist is open now.

If you've ever felt like your bookmarks, notes, screenshots, and saved posts are slowly turning into a pile of forgotten knowledge, we'd genuinely love for you to try and give us feedback.

Also curious:
When you save something "for later," where does it usually go - and do you actually find it again?
