Claude Code demo

See the savings on your own file.

Paste one prompt into Claude Code. It installs compresr, asks for a document + question, and prints a cost receipt with real numbers. ~60 seconds, no code required.

prompt.txt

Use compresr to show me live cost savings on my own file.

1. pip install compresr
2. Introspect the SDK to discover the API, don't guess.
3. Ask me for COMPRESR_API_KEY (open https://compresr.ai/signup if I don't have one: $10 free, no card).
4. Ask me for (a) a path to a long document (PDF/.md/.txt) and (b) a question about it.
5. Compress the document with the question, then print a receipt: tokens in/out, ratio, GPT-5.2 cost full vs compressed at $1.75/M input tokens, % saved.
6. Ask GPT-5.2 the question against the compressed context and print the answer.

Don't skip the cost receipt; that's the point.
