A second brain without the homework

Updated 13 October 2026. 2 minute read.

"Second brain" is the name for a simple idea: keep what you learn and collect somewhere outside your head, so you can use it later. The idea is sound. The systems built around it are often not. They come with methods, templates, weekly reviews and a vocabulary of their own, and the people who stick with them are mostly the people who enjoy maintaining them.

If you tried one and abandoned it, the idea did not fail. The overhead did.

What is worth keeping

Strip the methods away and three things remain:

• Capture quickly. If it takes more than a few seconds, you will not do it when it matters.
• Keep it in one place. A thought in Notes, a link in the browser and a PDF in mail are three things you will not connect.
• Be able to get it back by subject. Otherwise it is an archive, not a memory.

Everything else is optional: linking notes to each other, progressive summarising, elaborate tagging. These help some people think. They are not what makes the system useful.

The homework that can be skipped

Filing. Deciding where each item goes is the biggest cost and the first thing people stop doing. Software can file for you well enough.

Summarising by hand. Writing your own summary of every article is good for learning and unrealistic for the forty things you save in a month. A generated summary is enough to recognise an item later.

Weekly reviews. Useful if you like them. A library with good search does not rot when you skip one.

A version that survives

1. One inbox for everything. Links, photos, documents, notes, voice memos. The fewer exceptions, the better.
2. Save in two taps. From the Share Sheet, without opening the app.
3. Add a line only when it matters. Why you kept it, in your own words. Skip it otherwise.
4. A handful of broad categories, filled automatically. See folders, tags or nothing.
5. Search and ask when you need something. That is the whole retrieval side.

That is it. No graph, no templates, no method with a trademark.

Where Stashy fits

Stashy is built for exactly this small version. Each save is read once on your device and gets a summary, a category and hidden keywords. Search covers all of it by subject and across languages, and Ask Your Library answers a question from your own saves and shows which ones it used.

It deliberately does not try to be a writing tool. There are no linked notes and no outliner. If you think by writing long connected notes, a dedicated notes app is the right place for that, and Stashy can sit next to it as the place where the raw material goes.

A test for any system

Imagine yourself in a busy month, tired, on a phone, with one hand free. Would you still use it? If the honest answer is no, the system is too heavy, however elegant it looks on a calm Sunday.
