About ThoughtStream Lab
A private place to notice what you notice.
What ThoughtStream Lab does
ThoughtStream Lab is a quiet, private space for capturing thoughts the moment they arrive, by typing or by voice, and letting them accumulate until something meaningful surfaces. As your ledger grows, the assistant reads across your own entries and proposes where each thought sits on an evidence scale: from captured, to observed, to recurring, to confirmed. It also points out connections between ideas that you may not have noticed yourself. Nothing the assistant suggests is treated as fact until you accept it. Your original words are never rewritten, and every AI observation stays in a separate layer, so you can always tell what you wrote apart from what was inferred.
When a recurring theme is worth acting on, you turn it into a commitment and revisit it in a weekly review, so insights become something you actually do rather than notes that quietly pile up.
Notice
Capture what is on your mind in the moment, typed or spoken. No editing, no judgement.
Accumulate
Every thought lands in your private ledger with an evidence state, so you can see what you actually wrote and when.
Discover
The assistant reads across your ledger to surface recurring themes, contradictions and connections you may have missed.
Act
Turn what holds up into a commitment, then review it each week to see what changed.
Who it is for
ThoughtStream Lab is for anyone who thinks by writing: founders and makers working through a decision, writers and researchers tracking a theme over months, and anyone who wants a clearer view of their own patterns. If you keep a notes app full of half-formed ideas that never turn into anything, this is built for you.
Who builds it
ThoughtStream Lab is designed and built by a small team that cares about calm, private software. ThoughtStream Lab is owned and operated by SK America LLC, and it is SK America LLC that runs ThoughtStream Lab. There are no ads and no selling of what you write. Your entries are scrambled at rest, isolated per account, and yours to export whenever you want.

What it costs
Capturing what you notice, and reading it back, is free and stays free: text or voice, your ledger, evidence states, commitments and your calendar. A plan only pays for the assistant that reads the stream with you, and every account starts with a monthly allowance of assistant actions. Prices, what each tier includes, and how paying and cancelling work are set out on the pricing page.
