Athena Guide

Karpathy method + Second Brain. What to load and what NOT to load into memory.

— 02 How to use Athena

Not a memory dump. A thinking workshop.

Karpathy method + Second Brain. Athena turns chaotic thoughts into clear structure.

Rule

Don't collect information — develop ideas.

✓ Built for this

  • · Ideas and drafts
  • · Mini-projects in active phase
  • · Notes from current work
  • · Thought maps
  • · Connections between concepts

50–150 notes per project — magic.

✗ Don't dump "forever"

  • · Transcript archives
  • · Old correspondence
  • · Whole books
  • · Large datasets

The more archives — the slower and more expensive the work. Use Notebook LM for static stuff → distill into Athena. Notebook LM.

★★★★★

Replaced Notion, MyFitnessPal and CoinKeeper with one app. Athena actually keeps track for me — expenses by voice, food by photo, diary in the evening. Lifetime $49 paid for itself in a month.

Knowledge Galaxy is what I dreamed of after reading Tiago Forte. You see your thoughts as a living graph. Atrophy of some categories — visible. Not a "to-do list", a mirror.

BYOK = subscription fatigue killer. Plugged in my Claude API, paying ~$3/mo for real usage. PRIME+ Yearly $49 is the only subscription I don't want to cancel.

"First serious-look life OS with agentic AI. Athena doesn't just answer — it logs, schedules, rebalances. SnapEat photo→macros works more accurately than MyFitnessPal Snap."

Daily Flow with 9 domains is honest. If you forgot about health — the category dims. No guilt-tripping, just signal. Karpathy 48-min timer opened deep work for me.

Female cycle tracker built into one app — no need for Flo+Clue+nutrition separately. Athena remembers the phase and tailors workout/food/mood advice.
