It is where you **think and take notes** on all your beliefs, formulas and methods. It comes before your website, before your brand, and even before the Truth vault. Your Digital brain holds: - Your own thoughts and ideas - Other people's thoughts that you have understood - Role models you follow and want to copy - Your plans and what you intend to do next Because it holds plans, the Digital brain must stay private. ## Why keep every note private? The Digital brain is your **secret arsenal** against your competitors. The formulas and methods in it are yours alone. Only you know them, and that is your edge. It also holds the plans of your brand and of everything around it. Making these public hands an edge to other people. The Truth vault is the opposite: you make public what you really did, to gain an edge in competition, SEO and AI. Private does not mean one hiding place for each brand. ## Every brand shares one place ![Every brand shares one place](/docs/_astro/illus-docs-mot-ruong-nhieu-cua-hang.en.CullI2Hi_ZTKTiY.svg "One private place for every brand") If you have many websites and many brands, you **still have only one Digital brain**. It is the one place where you gather everything to manage it, sort it and think it through, before a brand shows up on the internet. Each brand has its own Truth vault, but all of them draw from the same Digital brain. Without that one place, many vaults will confuse you, because not every word goes into a vault. Both places keep what is yours, but they are different by nature. ## How is it different from the Truth vault? The Digital brain records **thoughts**, with no need to check them. The Truth vault records **work you have done**. When a thought is put into action and gets a clear result, that result goes into the Truth vault. The Digital brain keeps a trace of it as a link to the page in the vault. | | Digital brain | Truth vault | | --- | --- | --- | | What it holds | Thoughts, ways of thinking, plans | Work done, with results | | Who sees it | Only you | Everyone | | Rhythm | Daily notes | Daily updates | | How many | One for all brands | One for each brand | Everything you record, film, discuss or write goes into the Digital brain first. Then you work it into a clear result and a clear journey, and only then record it in the vault. ### Which notes make it into the vault? In one day you may do 10 or 20 things, but only a few of them make results. A note goes into the Truth vault when it passes two conditions: - **It fits the brand** of that vault - **You did it**, not just thought of it A note you have not acted on stays in the Digital brain. When you finish the work, you mark the note and turn it into a page in the vault. A view you have thought about for a long time, or a formula you have fully worked out, goes to the vault the same way. Since the vault is picked out of the Digital brain, the quality of the vault depends on what you put into the Digital brain. ## Only write down what you understood ![Only write down what you understood](/docs/_astro/illus-docs-nguoi-gac-cong.en.jFk7mnYw_ZTKTiY.svg "Only what you understood gets through") The Digital brain can hold anything, but **everything must pass a human filter**. You are the gatekeeper, the same rule as for the Truth vault. Two things do not go straight into the Digital brain: - **Content made by AI** that nobody has checked, because AI can hallucinate - **Other people's formulas and processes** copied word for word When you find a good formula from someone else, understand it first, then write it the way you understand it. Only then is it part of your Digital brain. :::note[20 notes or 1,000 notes] 20 notes a day that you truly understand are your data. 1,000 notes summed up by AI, scraped from outside or copied word for word are not a Digital brain any more. They are just a pile of information. ::: Writing it the way you understand it is also what sets the Digital brain apart from a familiar idea. ## How is it different from Second Brain? Second Brain is the name [Tiago Forte](https://www.buildingasecondbrain.com/) gave his method. The Digital brain is a term for **putting the human brain into digital form**. It is inspired by Second Brain, but it does not use the same formula. The Digital brain is simpler, fits the age of AI, puts results first and **puts publishing output first**. [BrainNode OS](https://brainnodeos.com/) is a Digital brain built on this idea, shared so that people who follow can shorten the road. A good Digital brain also needs to be used every day. ## When are notes left abandoned? The clearest sign is **a day with nothing new** in your Digital brain: you learned nothing that day, or you learned something and did not write it down. If you do not write it down, you rely on your biological brain to remember. About a month later, ideas and formulas start to fade and get dropped, sometimes even the most valuable idea. A note every day means the Digital brain is being updated. When the Digital brain is abandoned, the Truth vault loses its support too. ## Without a Digital brain, the vault loses direction A Truth vault without a Digital brain is **very hard to form**, because the vault has no direction. The structure of the vault is drafted in the Digital brain from the start: which ideas you need, which facts, and what must be made clear. When you write the vault, you only fill in the blanks. What you will say in the vault is already saved in the Digital brain. Without it, the vault is written by feel, with no direction. ## Related pages - It does not cover the daily habit of learning and sharing: see [Capture and Share](/docs/content-system/truth-vault/capture-and-share). - It does not make anything public: the public part is [Entity docs](/docs/content-system/truth-vault/open-docs). - It does not draw the tree of the vault: see [Docs structure](/docs/content-system/truth-vault/guides/tutorials/docs-structure). - The story and the view behind this page are in [How are business docs different from notes and a blog?](https://cuongthach.com/business-docs-vs-notes-and-blog/).
