What Are Tokens?

Tokens are the study fuel behind every Custom Backup AI feature.

Tokens are the study fuel behind every Custom Backup AI feature.

Quick Answer

Tokens are the units AI uses to read and write text.

When you type something in, it's split into tokens.

When the AI replies, it spends tokens.

Think of tokens like MBs of mobile data, the more you do, the more you use.

How Tokens Work

Most words = 1–2 tokens.

Example: "The mitochondria is the powerhouse of the cell." → ~10 tokens.

Both input and output cost tokens.

Asking a short question costs fewer tokens than pasting a long essay.

Bigger tasks = more tokens.

Creating a full Custom Step costs more than a single Explanation.

Why We Use Tokens

We could have hidden all this and said "unlimited." But that would be a lie.

  • Transparency: you know exactly what you're paying for.
  • Flexibility: you decide how to spend them, more Creates, more Notes, more Explanations.
  • Future-proof: just like MBs became normal, tokens will too. By 2030, tokens will be as standard as emails or scrolls on TikTok.

Token Equivalents in Custom Backup

We translate tokens into real study actions so you don't need to count:

CB Create

45K tokens ≈ 3 Creates

CB Notes

20K tokens ≈ 10 Notes

CB Explanation

10K tokens ≈ 20 Explanations

CB Images

100K tokens ≈ 50 Images

So when you see "300K tokens," think: "That's about 20 Creates or 150 Notes."

CB Marker - Gradient Tick (Smaller)Why Markers Are Different

Most AI features in Custom Backup run on tokens. But CB Marker works differently.

What it is:

CB Marker checks whether your answer is right or wrong.

Why it's separate:

  • Each check is a fixed, simple action, one answer, one validation.
  • It doesn't make sense to measure these in tokens because the text length is tiny and predictable.

So we track them as units (1 marker = 1 answer checked).

Plan breakdown:

  • Free: 50 markers/month → enough to trial recall testing.
  • Plus & Pro: Unlimited markers → every answer can be tracked without limits.

Bottom line: Tokens measure generation power (AI creating content).
Markers measure validation power (AI checking answers).

How It Works Across Plans

Free

Just a taste. Enough to explore, not enough for serious revision.

Plus (£4.99/month)

Serious studying. Enough tokens for consistent use, with Advanced Mode unlocked.

Pro (£11.99/month)

Creative freedom. Max tokens + publishing + recognition (Custom Distinctions).

Final Word

Tokens aren't confusing, they're just the currency of AI.

  • Free lets you experiment.
  • Plus gives you serious revision power.
  • Pro gives you creative freedom and recognition.

Instead of fake "unlimited" promises, we give you real numbers you can trust.
