Claude Forgets Everything.
Every. Single. Session.
You spend 15 minutes per session re-explaining who you are, what you do, and what you decided yesterday. MemoryOS gives Claude a local SQL database with 14 queryable collections, confidence scoring, and full-text search. Permanent memory you own, searchable instantly, validated automatically.

Watch how MemoryOS catches a $3,000 mistake before it reaches your client.
The Hidden Cost of AI Amnesia
You waste 65 hours/year re-explaining context to Claude.
At $75/hr, that costs $4,875/year.
That's 8 full workdays per year — gone to re-explaining.
MemoryOS is $199/year.
Your Memory. Your Database.
Your Rules.
14 queryable collections in your local SQL database. Not chat history — structured data with schemas, confidence scores, and full-text search. A local database on your laptop or your own Supabase project. Nothing leaves your computer unless you choose cloud.
What MemoryOS does for $199/year:
Powered by Model Context Protocol
One Command. Permanent Memory.
MCP is the USB port for AI — a standard protocol that lets Claude connect to external tools. MemoryOS plugs into that port and gives Claude a brain that persists.

Same Prompt. Different Memory.
The difference between Claude with and without persistent memory.
Prompt: "Draft a proposal for Acme Corp"
I don't have information about Acme Corp. Could you provide details about the company, your relationship, past interactions, and what services you'd like to propose?
Based on your 3 previous interactions with Acme (last: March 3), Sarah Chen's preference for async communication, and your updated Q2 pricing... here's a draft addressing their budget concerns from last quarter.
Prompt: "What did we decide about the pricing change?"
I don't have any record of pricing discussions. Could you share the context?
On Feb 15, you decided to increase consulting rates from $200/hr to $250/hr. Rationale: market rate adjustment + 2 new certifications. You considered $275 but rejected it to keep the anchor client. 3 proposals still reference the old rate — want me to update them?
Prompt: "Prep me for my call with DataCorp in 20 minutes"
I'll need some background. Who is DataCorp? What's the call about? What's your relationship history?
DataCorp call prep: They're evaluating your Q2 proposal ($45K). Tom Rivera (VP Ops) will be on the call — he pushed back on timeline last time. Key concern: implementation speed. Your advantage: you delivered Phase 1 for Acme in 3 weeks vs their 8-week estimate. Lead with the Acme case study.

"How do I know if my memory system is good?"

Quotes from Second Brain customers. MemoryOS is the memory engine inside every Second Brain.
Gabe Marusca
20+ hrs/week saved
"Before the Second Brain, I spent 30 minutes prepping for every client call — pulling up old notes, re-reading proposals, trying to remember what we discussed. Now I type /prep and get a complete brief with their history, concerns, and my recommended approach. In my voice."

Sharon Greene
Futurist — Zero technical skills
"I had never opened a terminal before this. Now I type one command and get my email, calendar, and WhatsApp in one daily briefing. I genuinely said out loud: one command does all this?"
Wouter van den Bijgaart
AI Developer — Replaced DIY setup
"I built my own system and spent 3 hours a week maintaining it. MemoryOS does the maintenance automatically — the propagation alone saved me from constantly updating my assistants manually."
Shaun
Marketing Operator — 85% faster
"My first drafts barely need editing anymore. The Brain knows my audience, my themes, and how I structure posts. It went from a starting point I had to rewrite to something I just polish."
Andrew Shaw
Professional — 60% faster output
"Job applications used to take me 30 minutes each. Now the Brain writes them in 12 minutes because it knows my experience, strengths, and writing style."
"I almost didn't buy. I've abandoned Notion, Obsidian, and two 'productivity systems' before this. But MemoryOS was the first one that maintained itself even during a 2-week vacation. I came back and it had kept my context fresh. That's when I knew this was different."

The real cost of scattered AI
Even conservatively — if MemoryOS saves you just 2 hours per week, and your time is worth $75/hr, that's $600/month in reclaimed time. At $199/year, it pays for itself in less than 2 weeks.
