Understanding Credits and Usage

How BrainTube credits work, what actions cost credits, and how to manage your usage.

BrainTube uses a credit system for AI-powered features. Here's how it works.

What Are Credits?

Credits are the currency for AI operations in BrainTube. Every AI-powered action (enrichment, chat, search, quiz generation) costs a small number of credits.

What Costs Credits?

Save & Enrich~2 creditsSaving a new item with AI enrichment
Brain Chat~1 creditAsking a question to a Second Brain
Quiz Generation~1 creditGenerating a knowledge quiz
Deep Search~1 creditRunning a graph-enhanced search

Free Tier

All new users receive free credits to get started. The free tier includes enough credits to save and enrich 10-20 items, have several brain chat sessions, and try the Knowledge Playground.

Checking Your Balance

Your credit balance is always visible in the sidebar. Click it to see a detailed breakdown of your usage history.

Getting More Credits

  • Purchase credits — Buy additional credits à la carte
  • Membership codes — Redeem promotional codes for bonus credits

Tips to Optimize Usage

  • Batch-save content rather than processing one at a time
  • Use keyword search for simple queries (doesn't cost credits)
  • Star important items to avoid re-searching for them
