Whether you're a tech person who's a little lighter on the business side—or a business person who understands how one extraordinary idea can change the course of an entire company and the lives of its founders and everyone involved. While .MD Brain refreshes Cursor without losing the valuable knowledge, using A.I. + Your Guidance + Our Secret Sauce, .MD Brain builds a living Deep Mind from your .MDs, continuously turning accumulated knowledge into Golden Goose Eggs—dramatic breakthrough business ideas, insights, and additions to your .MDs that could dramatically increase revenue, accelerate signups, uncover extraordinary opportunities that could transform your company's entire future and the Founder's life.
Be The Golden Goose
Guided by the strategies you choose — in effect, telling the Golden Goose what kind of Golden Eggs you want — .MD Brain looks for unexpectedly valuable ways to grow revenue, reach new customers, find strategic partners and reshape your business. Your ideas appear in your web Admin Command Center, and the most promising are emailed to you on the schedule you set.
What we do that NO ONE ELSE DOES is brought to life through our name and slogan — a living Deep Mind that never stops learning, uncovering breakthrough ideas and opportunities that could transform your company and change your life.
Your .MDs Already Know Your Company. We Look For What They Could Make Possible.
Product specs, business plans, features, decisions, strategies and insights you already build while working in Cursor.
AI connects what is spread across your approved files, Guidance, Strategies and valuable development history.
Potentially transformative opportunities in revenue, distribution, partnerships, new products and company strategy.
When an insight is sufficiently meaningful, Golden Goose emails its reasoning and suggested next steps to the founder.
Ideas are recommendations to evaluate, not guaranteed business results. Golden Goose reads approved .md files only. You choose that scope.
A real Golden Goose insight
A founder was trying to acquire users one at a time. A much more powerful strategy emerged from the Golden Goose.
Grow by calling Realtors & mortgage brokers individually — one prospect at a time.
Distribution breakthrough
Build an API + embeddable buttons that plug your referral platform directly into established PropTechs and Real Estate Media sites that already have massive user bases. Give these partners 30% of the referral fees generated by every one of their users, with each Home Buyer referral worth up to $2,000. In return, they instantly open their entire user base to us, while a simple, turnkey integration could generate an entirely new SIX- or SEVEN-FIGURE MONTHLY revenue stream for them!
.MD Brain's Golden Goose mission is to find higher-value possibilities across your business — especially ones you may not think to ask about while you're focused on building software.
Types of ideas .MD Brain can look for. These cards are illustrative, not customer outcomes.
One platform with hundreds of thousands of users—whose founders can earn a share of every referral fee those users generate—can be far more powerful than recruiting each user individually.
A capability already built into the product might be licensable to another buyer segment.
Another company may control the audience, channel or complementary product the founder needs.
A product built for one market may solve a commercially valuable problem in a neighboring industry.
An alternative pricing, platform or partner-incentive model might unlock compounding growth.
An internal capability might be separately marketable as an API, add-on or service.
The greatest value may come from the connection you didn't know to make.
Your next big business idea could arrive by email. .MD Brain reads the .md knowledge you've already built, keeps learning about your business, and looks for unexpected opportunities to increase revenue, reach new markets, find strategic partners or change your company's direction. When Golden Goose uncovers an insight worth your attention, it can email the opportunity directly to you — without you needing to know the question to ask.
Opt in from the Golden Goose tab and pick a daily, weekly, or monthly look. Each email can include up to ten ranked ideas that answer the strategies you turned on. Rank 1 is the main idea for Revenue Maximization. A strategy with no new idea is listed as a placeholder so you always know it was checked.
Illustrative Golden Goose Idea
From: .MD Brain — Golden Goose
Your project files describe capabilities that may be valuable to established platforms. Rather than recruit each customer individually, consider offering an integration that lets a platform introduce your product to its existing audience.
Why it matters. One successful platform relationship could potentially provide access to many customers through a single integration.
Why this idea is relevant. Based on your own documented API architecture, user-acquisition plans and target-provider categories.
Next steps. Validate partner audience fit, economics, integration requirements, and a small pilot.
Example opportunity. This describes the type of recommendation. It is not a claim that this HomeBuyerProviders idea was originally delivered by automated email, and it is not a measured result.
You've already invested years of thinking into your product, plans and .md files. .MD Brain's Golden Goose mission is to connect that knowledge into ideas that could open entirely new paths for your business.
Start Building My Deep Mind Explore Everything Else Included
The Golden Goose is the mission. And that's just the beginning.
Everything below makes .MD Brain even more valuable.
The same product still keeps Cursor fast, protects chats, and writes useful knowledge back into your approved .md files.
Organized .MDs
Go-Back Protected Full File Update and Auto-deposits each receive a versioned restore point before MD.Brain writes to your approved .MDs. Go-Back removes later .MD Brain additions only; your own writing stays. Use Web Admin → History & .MD Viewer → .MD Version Go-Back.
Asking Cursor to paste chats into an .MD only keeps the raw thread. MD.Brain reads those chats against your Guidance and Strategies and writes auto-deposits in the scope you set — more signups, more revenue, a leaner company, and the other outcomes you ask for. Both capabilities draw on your .MDs, Guidance, Strategies, and valuable Cursor knowledge. Full File Update can curate deposits and refresh the Summary — length scales to the .MD (short files stay ~500 words; large specs may use 2,000+). Your original content outside managed sections is never changed. After install, set Approved Scope, then enable Auto-Sync, Smart .MD Deposits, and Smart .MD Summaries in Your Guidance.
.MD Brain learns from your .MD files on the left, and from Strategies, valuable Cursor knowledge, and project decisions on the right. Guidance and Strategies also sit above the Brain. A simple loop connects your Cursor work, preservation, Smart .MD Deposits, Summary and Suggestions, and better context for the next session.
.MD Brain Lightweight Knowledge Context
Cleaner / Faster Cursor • Useful Suggestions Smart .MD Deposits • Organized .MDs
Chats • code • decisions
Capture signal • KEEP / DISCARD
Codex + Guidance → correct .MD placement
Excerpts • rationale • Go-Back
Lean Cursor → smarter next session
Cloud Brain
What MD.Brain Cloud adds beyond the local Cursor session. Cursor is where valuable work happens. MD.Brain Cloud makes sure the valuable knowledge, reasoning, history, and codex state can continue to exist and remain useful — even after local Cursor data is cleaned.
MD.Brain Cloud gives your company’s intelligence continuity. Cursor sessions can end. Chats can be cleaned. Developers can switch machines. A Full File Update can refresh summaries or curate deposits. Your codex history, deposit rationale, and valuable chat signal can remain available through MD.Brain.
Version history for your living codex.
Before managed AI changes — Full File Update and Auto-deposits — MD.Brain creates a versioned restore point for the approved .md. Preview and restore from Web Admin → History & .MD Viewer → .MD Version Go-Back to remove later .MD Brain additions only. Writing you added manually or otherwise stays in the file.
Per-file recovery in Web Admin — separate from desktop Cleanup → Go-Back Tools (chat database and Cloud Brain database backups). MD.Brain can improve the Brain without forcing you to trust every AI change permanently.
The valuable signal survives local cleanup.
When Cursor work is synchronized, MD.Brain Cloud preserves useful conversation signal — curated excerpts and bounded metadata, not a blind upload of the entire local Cursor database:
.mdInspect what mattered through History & .MD Viewer even if the original local Cursor conversation was removed during cleanup.
Delete local weight without creating organizational amnesia.
Your local chat can disappear without taking all of its useful history with it.
Keep the knowledge, not just the database row.
Telling Cursor to record chats into an .MD only leaves the raw conversation in the file. MD.Brain reads those chats through your Guidance and Strategies and deposits useful, in-scope knowledge — ideas that raise signups, raise revenue, or make the company leaner.
The most valuable outcome is not storing old chat records forever. MD.Brain converts useful Cursor knowledge into durable codex intelligence, making Smart Deposits into the appropriate approved .md at the top, bottom, or contextually appropriate location according to your settings. Smart Summaries & Suggestions still maintain their dedicated managed section. Inspect the history and rationale behind every deposit.
MD.Brain doesn’t preserve valuable work merely as cloud database records — it deposits useful knowledge back into the living .MD codex.
The real HomeBuyerProviders distribution suggestion that came out of this kind of deposit is in the Golden Goose story above. It is a strategy shift, not a measured revenue result.
Raw conversation history is temporary. Useful company knowledge should not be.

Living company Brain
MD.Brain’s cloud layer enables this sequence — cleanup comes last, after the important signal is already safe.
Capture the valuable signal.
Determine what deserves to survive.
Understand the work using the codex + Guidance.
Preserve knowledge in the appropriate .md — placed where it belongs.
Retain excerpts, decisions, rationale, and Go-Back recovery points.
Remove unnecessary local weight with dramatically more confidence.
That is why your .md codex becomes a living company Brain instead of a folder full of markdown files.
By the time MD.Brain recommends cleaning local Cursor weight, the important knowledge is already safe in your codex, Cloud Brain, History, and Go-Back versions.
state.vscdb footprint.md codex via Smart Deposits and summariesCursor slows down when chat history, Composer database rows, and cache pile up on disk. .MD Brain does not offer one blunt delete button — you get a customized cleanup toolkit for every situation, only after intelligence is preserved in Cloud Brain. Customer .md files are never deleted.
Quick targeted cleanup functions.
When you already know what you want, skip the guided path. One-click presets like After audit (recommended) and Maximum squeeze, plus individual actions: clear Cursor cache, refresh Bog Down stats, delete audit-flagged chats, clear logs, shrink the Composer database, and more. Mix and match checkboxes — preview the batch, confirm, then run.
Full guided cleanup workflow.
A stepped operator console on the Windows/Mac Desktop Widget Cleanup tab. Step 1 Sync captures signal to Cloud Brain before cleanup continues. Step 2 Audit marks what is safe to clear. Step 2.5 Protect Cursor Chats (desktop-only, featured above) lets you search, review, and save the chats you need locally. Step 3 What to Clean runs only what you checked — with live progress, backup first, and desktop confirm modals.

Know how bogged down Cursor is before touching anything.
Live Bog Down score, Cursor disk footprint, chat file count, cache size, and audit keep/discard counts — so you know whether cleanup is worth running before you touch anything.
Use targeted cleanup when you already know exactly what you want.
Apply presets like After audit (recommended) or Maximum squeeze, refresh stats, clear cache, and mix individual actions with preview + confirm.
Then walk the guided path from top to bottom.
Guided Sync, Audit, then run only what you check in Step 3. Protect Cursor Chats lives on the Windows/Mac Desktop Widget (desktop-only picker). Cleanup is desktop-only — Web Admin is Monitor, Your Guidance, History, and Settings.
Preserve the valuable knowledge first.
Step 1 Sync uploads your .MDs to the cloud before cleanup continues. Smart .MD Deposits and managed Summary & Suggestions sections update for approved .MDs when those features are on.
Mark what is safe to clear — automatically.
Run Full Audit using your Delete and Overlap thresholds — no manual chat-by-chat review required.
Save the threads you still need before anything destructive runs.
Search every chat, open any one in .MD Brain Chat Viewer, then toggle ON what must survive Step 3.
Run only what you checked — with preview and confirm.
Delete flagged chats, clear cache, shrink Composer DB, and more. Backup first, live progress, desktop confirm modals.
Every destructive step previews first and asks for desktop confirm — customer .md files are never deleted.
Search → Read → Protect
Bulk cleanup should never delete the threads you still need. Protect Cursor Chats lets you search every chat on this computer, open any one in the .MD Brain Chat Viewer to read it first, then toggle it ON so Auto-Clean Step 3 skips it. Synchronized excerpts and audit history remain in Cloud Brain even when the local chat is later cleaned.
Filter by title or keyword — every Cursor chat on this PC appears in All Results, newest first.
Click any row to open the .MD Brain Chat Viewer — read curated excerpts and audit context before you decide.
Flip the switch ON for chats you want to keep locally. They move to Chats You Chose To Protect and survive Step 3 cleanup.
Restore · Recover · Go Back
Things go wrong. Large cleanups, accidental deletes, or a fresh Cursor start shouldn't mean losing everything. Go-Back gives you multiple layers of recovery:
Before Smart .MD Deposits or Full File Updates, MD.Brain creates a versioned restore point. Web Admin → History → .MD Version Go-Back removes later .MD Brain additions while keeping writing you added yourself.
Before cleanup, Go-Back Tools can snapshot your entire state.vscdb to a local folder (Dropbox, lab folder). Restore a clean baseline whenever needed.
Your protected chat metadata, audit history, and cloud settings live in mdbrain.sqlite. Go-Back backs this up before any major cleanup — restore admin panel state independently.
When you protect a chat, MD.Brain stores its sidebar stub in the cloud. After a fresh Cursor start, one click re-injects those protected chats back into the sidebar — no need to restore a 75 GB database.
Go-Back Tools lives in the Windows/Mac Desktop Widget Cleanup → Go-Back Tools tab. All snapshots are stored locally — no sensitive data leaves your machine.
MD.Brain maintains an organized Summary & Suggestions section while also making intelligent Smart .MD Deposits directly into your approved .MDs — at the top, bottom, or where the information belongs, based on your settings.
Telling Cursor to record into your .MDs only drops in raw chat. .MD Brain does more. You provide Guidance and Strategies, and it reads your chats and translates them into auto-deposits inside the scope you care about — suggestions that raise user signups, raise revenue, or make the company leaner. Real useful information, according to your guidance and desire.
Cursor Projects
Cursor "Projects" lets agents accumulate shared context and draw from your .MDs — making the knowledge .MD Brain protects, organizes, and curates into your .MDs even more valuable. .MD Brain gives Projects a cleaner, smarter knowledge base to learn & work from, making Cursor Projects much more useful. That's just one of the reasons why we say .MD Brain is "Cursor's Perfect Side-kick."
Your knowledge. Your files. Your rules.
| Cursor Projects | .MD Brain | |
|---|---|---|
| Knowledge Control | Agents maintain shared Project context | You decide which .MDs AI can work with through Approved Scope, with separate permissions for .MD Deposits & Summaries and Full File Updates — so AI only writes where you explicitly allow it. |
| Visibility & History | Shared Project context is available within Cursor | See your actual .MD knowledge, Smart Deposits, deposit rationale, chat excerpts, history, and previous .MD versions in our custom viewers — with Go-Back when needed. |
| Where Knowledge Lives | Shared context maintained for Project agents | Important knowledge is deliberately written into your own organized .MD codex — in the right file and, based on your settings, at the top, bottom, or where it belongs. |
| What AI Can Change | Project agents maintain their shared context | Per-file Approved Scope lets you independently authorize .MD Deposits & Summaries or Full File Updates — including allowing one without the other. |
| Relationship to Cursor | Built into Cursor to execute and coordinate development work | A complementary intelligence-management layer designed to improve the quality, structure, and lifecycle of the knowledge Cursor creates |
| Knowledge Organization | Accumulates shared context for Project agents | Designed to refine useful information and deliberately place it into the right .MD files instead of simply allowing context to keep accumulating |
| Cursor Cleanup | Cursor Projects does not offer this | Auto-Clean removes accumulated Cursor clutter while protecting the valuable chats and intelligence you want to keep. |
| Primary Purpose | Persistent shared context for Project agents | Create, build, organize, preserve, and curate your knowledge resulting from ongoing work into .MDs that build a Deep Mind, while helping keep Cursor clean and fast + turn that .MD knowledge into smart auto-deposits & "Golden Goose suggestions" that may change your entire project, company, and life. |
Telling Cursor to save something to an .MD preserves data, not useful information. .MD Brain goes further — it turns knowledge you build in Cursor into a living knowledge system — a Deep Mind just for your ongoing development.
Using your Guidance, Strategies, Approved Scope, existing .MDs, and valuable Cursor chats, .MD Brain continuously strengthens your codex with Smart .MD Deposits, Summaries & Suggestions — putting useful knowledge into the right .MD, where it belongs and building a Deep Mind that is absolutely invaluable.
As the intelligence is auto-preserved, .MD Brain helps you clean away the Cursor clutter.
Keep the knowledge. Improve the Brain. Clean the clutter to keep Cursor fast. Be The Golden Goose.
