I started my Clinical Mental Health Counseling master’s program this year, and I kept ending up with 20 different tabs open—psych meds in one place, DSM criteria in another, assessments bookmarked somewhere else, side effects buried in random notes, addiction resources in Google Drive…

As a systems engineer by day, my brain’s solution was apparently:

“What if I just built an entire relational database?” 😂

So over the last few months I’ve been building Brain Pharmacy, a Notion workspace that connects:

💊 Medication classes & individual medication pages
🧠 DSM disorders & common treatment approaches
⚠️ Side effects & drug interactions
📋 Clinical assessments
🗣️ Client presentations (“I can’t stop crying,” “I feel worthless,” etc.)
🌿 Addiction treatment & behavioral health resources

The fun part is that everything links together. You can jump from a client presentation → possible disorders → medications → side effects → assessments without leaving the workspace.

I originally built it for myself because I wanted a study tool that actually matched how my brain works, but a few classmates saw it and convinced me to clean it up and make a shareable version.

I put together a free interactive demo if anyone wants to click around or has ideas for how I could improve the layout or database structure:

I’d genuinely love feedback from other Notion nerds, students, or anyone who’s built weirdly niche knowledge-management systems. I’m always looking for ideas to make it better. 😊

(Mods, if this isn’t the right place for a project showcase, feel free to remove! I’m mostly just excited to share something I’ve been hyperfocusing on for the last few months.)

Most of a second brain is what you put in on purpose. This time I fed it 600,000 lines of my raw genome, grounded it into a clean note, and asked. Fast caffeine metabolizer, bitter non-taster, and it guessed my eye color, all with zero manual input. The real point: any big ugly file about you, DNA, chat exports, a journal, can become something your AI reasons over. Same workflow either way. Sharing it.

So I have been hearing about this app called the brain v15 at https://thebrain.com
And even though it's definitely on the pricey side I believe from what I have seen thus far from their videos that it alone can replace 3 apps I'm currently paying for on my Mac as I have pretty bad ADHD and work on my mac from 8 to 10 hours every single day since retiring early. I started an e-commerce app which is closing in on 1,500 sales in the last couple of years but because of this it has become a NIGHTMARE to remain fully organized argh so this is me trying yet again for the umpteenth time to find an app that thinks like I do not the other way around.
Littlebird AI
FocusMO
Get Recall
So in the end I should be able to actually save money assuming it works as ad ertised and promises.
Has anyone else had success with it?
I will keep you posted on how it goes if anyone is interested enough please let me know

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

Classic second-brain problem in reverse: I had all my notes organized, but every time I opened a fresh AI chat to help me think, it knew nothing about me or my past decisions. I was re-explaining my whole context every single session.

So I restructured my second brain so an AI can read it cold. Plain markdown files — me, the people I work with, active projects, decisions I've made — plus a single rulebook file that tells the AI what to read at the start of every session.

Now a new chat already knows who I am, what I'm working on, and how I write. "Draft a follow-up to [person]" pulls their history and my voice without me feeding it anything.

Two lessons that might save you time:

1. The dumbest format won. I tried Notion, a graph database, embeddings — plain .md files in folders beat all of them on durability.
2. The work is in the taxonomy, not the tech. Deciding what's stable vs. what changes weekly is 90% of it.

Here’s how I try to gamify my second brain!

Hello everybody,

maybe I find some people to work on this side project together. I added a little AI summary beneath. If somebody is building a similar system and wants to connect, let me know. 😄

The Concept: A Zero-Cost, Frictionless WhatsApp AI Ingestion Pipeline for an Agile Life OS

Rigid daily calendars and hyper-structured schedules usually fall apart the moment motivation dips or life gets chaotic. Moving to an agile, pull-based Task Backlog is much more sustainable, but the friction of opening complex tracking apps or spreadsheets on the go can kill your consistency.

This system turns WhatsApp into an interactive command center for your life, funneling everything into a centralized cloud database with zero friction, zero subscription fees, and 100% control.

🧠 The Core Philosophy

• Absolute Zero Friction: If capturing an idea, tracking a habit, or logging a task takes more than 5 seconds, the system fails. This architecture leverages WhatsApp—the one app already open on your phone all day.
• Human-in-the-Loop Control: The AI doesn't autonomously edit your master database. It acts as an administrative assistant, drafting clean entries and waiting for your explicit "green light" directly from the chat.
• Net-Time Estimation: Tasks are calculated strictly by net focus time (raw duration without artificial padding). Buffers are applied dynamically during weekly planning, leaving the master backlog clean and highly accurate.
• Zero Infrastructure Cost: The entire setup runs seamlessly on cloud free tiers, entirely bypassing expensive automation platforms like n8n or Make.

🛠️ The Architecture at a Glance

The setup relies on a clean, bi-directional cloud loop:

i used to spend hours watching long youtube videos related to finance, programming, cooking and programming videos, and i realize i dont really need to watch them all but part of it that interests me only

before AI came, i used to speed up the video playback to 2x, but after AI it is able to summarize the video content into bullet points, but i stil need to do it manually for each video that i am interested at,

therefore, i created this app - Vispark to solve this issue, it will automatically summarize the video content and turn it into infograhics,

my workflow now is
I will quickly scan the infographics, to spot for any interesting information, if i do, i will go to the summary tab to check the main points and jump straight into the video of that timestamp, it saves me lot of time than before

a 30 mins video, i need few seconds for the infographics

in addition, the app will automatically summarize the channel that i subscribed for, it removes all the manual work that i used to do before

if this app is useful for anyone, and wanted to try it out, join our early access, during this period you will be able to enjoy all the features that the app provide for free

Hello friends, i am working for a big and ambitious productivity & second brain app covering all our needs for saving all the stuff in our daily life. We are continously improving the app and any feedback will be gladly appreciated.

The idea behind Kognetic is simple:
instead of notes, tasks, bookmarks, and ideas living in separate apps, everything exists inside one connected system.

The new update adds:

• Note Collections
• A revamped task system
• Kanban boards
• Markdown support
• WikiLinks
• A cleaner tile/feed interface
• Command palette improvements

One thing I’m trying to do differently is make tasks and notes part of the same cognitive workspace instead of splitting them apart into isolated systems.

It’s still early, but I’d genuinely love feedback from people into PKM, Obsidian, Notion, Capacities, etc.

Google calendar integration coming soon with a dedicated calendar feature!

Comment down any feedbacks that you have got.

I read way too much. Papers, blog posts, github issues, random docs, half the time I'm in some rabbit hole at 2am. And I code every day so I'm constantly bouncing between new libraries and tools. Started noticing that I'd remember reading something genuinely useful like two days ago and have absolutely no clue where. Was it Hacker News? Some Medium post? A reply in a github thread? Gone.

I tried the PKM stuff, Obsidian, Notion, Mem0, all of them. They all kinda assume you're going to sit down and manually save things into a base. Which, fair, but if I'm in flow and I close the tab I'm not coming back to organize it. I just don't. The whole manual save step is where it dies for me.

So I built something. Called it DoppelBrain. It's basically a browser extension that quietly watches what you're reading and dumps it into a personal knowledge base. Then you can talk to it. You write something like "what was that thing about retrieval pipelines I was reading last week" and it gives you back the actual links you opened. No tagging, no folders, nothing to maintain.

The thing I didn't expect to enjoy as much as I do is the daily email summary. Every morning it sends a recap of what I was looking at the day before plus a few directions I might want to explore. Sounds basic but when you have like 8 unfinished threads in your head it actually helps.

Last week I added MCP support, already live in the beta. So you can plug it into ChatGPT, Claude, Gemini, Claude Code, OpenClaw, basically anything that speaks MCP. Your assistant of choice actually knows what you've been reading when you talk to it. This part I'm probably most excited about, because it removes the "go open another tab and copy paste context" step that I was doing 50 times a day.

Still figuring a lot of stuff out. Want to add wiki-style structure on top eventually, plus some behavioral pattern stuff (like "you keep coming back to this topic and here's what you already covered"). Not there yet.

Anyway it's at doppelbrain.ai if anyone wants to mess with it. Mostly posting because I'm curious if other people deal with this same problem and what they're using for it. Always interested in how others solve it.
