Why Pith Lab? On principles and the workshops that make them real.
Pith was always the principle: what remains when you boil reading down to its essence. The lab is where that distillation actually happens, week after week.
In short
Pith is the principle — the essence of what you read, retained and returned to under pressure. Pith Lab is the practice: the tool that distils your reading into a cited, compounding wiki you can actually use before a client call.
The team behind Pith Lab

A principle is not a tool
For two years, the name Pith described the principle: the essence of what you read, retained, returned to when you needed it. Consultants who try the product get the principle within five minutes. The principle is the easy part.
The hard part is the workshop where the principle becomes work. Reading happens daily. Distillation happens continuously. Recall happens under pressure, ten minutes before a client call. None of that is a principle — it's a practice. And a practice needs a place.
The lab
A lab is where experiments happen, where instruments are kept calibrated, where what was learned last week informs what's tried this week. Old scientific labs — Marie Curie's, Faraday's, Lavoisier's — were physical spaces that compounded knowledge over decades. The lab is where the work of the principle lives.
Pith Lab is the lab for the principle of reading-as-essence. You bring your reading in; the lab processes it. Bookmarks become highlights become concept pages become briefings. The library compounds week by week. The lab keeps running while you're in client meetings.
Same idea, more honest name
The principle didn't change. The name is just more honest about what the product does — not just what it is. The product is a working knowledge lab, not a sealed concept.
Pith is the principle. Pith Lab is the practice.
Same product, two parts of the same word.
FAQ
What does 'Pith' mean?
Pith is the soft core at the centre of a plant stem — the marrow, the essential part. As a principle it means the essence of what you read, kept and reused. As a product, Pith Lab is where that distillation happens automatically.
Who is Pith Lab for?
Consultants, analysts, and small advisory teams whose work depends on reading a lot and being able to find what they read again — especially ten minutes before a client meeting.
How is Pith different from Notion or NotebookLM?
Notion rewards authoring; Pith rewards reading and builds the wiki for you. NotebookLM works in batch uploads; Pith captures continuously and keeps every client's knowledge current.
Do I have to write anything?
No. You bookmark and highlight as you read; Pith's agent writes the cited concept pages in the background. The principle is capture beats authoring.
Why the name 'Lab'?
A principle needs a place to become practice. The lab is the workshop where reading is distilled, kept, and put back to use — week after week.
