About this tool
What is Prompt Context Packager?
Drop source files, add instructions, and export a single structured markdown block with fenced code, optional file tree, and approximate token counts suited for Cursor, Claude, Gemini, and similar tools.
FAQ
How accurate is the token estimate?
It uses the same BPE-style heuristic as Prompt Architect (~95–98% vs tiktoken for GPT-family text). Treat it as a planning aid, not a billing meter.
Is there a file size limit?
Only your device memory and browser UI. Very large packs may feel slow to edit or copy — prune before shipping to an LLM.
