The Scaling Problem

CLAUDE.md hits context limits. Continuity scales infinitely.

Token Growth: O(n) vs O(1)

CLAUDE.md grows linearly with decisions. Continuity stays constant.

Context Window Limit (200K)

CLAUDE.md hits the 200K context limit at about 968 decisions and becomes unusable.

At 1,650 decisions CLAUDE.md would require 336,704 tokens - about 168.4% of the context window. Continuity stays at 14,472 tokens for the current benchmark.

Real-World Scenario: "What did we decide about authentication?"

With CLAUDE.md Only
  1. 1.Claude loads all 1,650 decisions (336,704 tokens — 168.4% of the 200K context window)
  2. 2.Claude scans through everything manually
  3. 3.You've already used 168.4% of context before even asking
  4. 4.Doesn't work - exceeds the context limit
With Continuity
  1. 1.Claude calls search_decisions("authentication")
  2. 2.Returns only the relevant decisions (~14,472 tokens at the benchmark)
  3. 3.You've used just 7.8% of context
  4. 4.Works with room for long conversations

The Verdict: They Work TOGETHER

Use CLAUDE.md for:

What to do (instructions)

Use Continuity for:

What we decided (memory)

CLAUDE.md and Continuity serve different purposes. They're not replacements - they're complements.

Key Insight: Savings increase as your project grows.

The more decisions you log, the more efficient Continuity becomes. At 10,000 decisions, you save nearly 99.4% of tokens.

FAQ

Why is Continuity more efficient than CLAUDE.md?

CLAUDE.md loads ALL decisions (O(n)). Continuity retrieves only relevant ones (O(1)). At 1,650 decisions: 95.7% savings.

What happens past 968 decisions?

CLAUDE.md exceeds the 200K context window. Continuity keeps working.

How much money will I save?

$580.02/month or $6960.21/year in benchmark-model savings.

Is my data secure?

All decisions stored locally in .continuity/ — never on our servers.

What AI assistants work?

Claude Code, Cursor, GitHub Copilot, Google Gemini, and more via zero-click setup.
