4 free tools — no ads, no sign-up, everything runs in your browser.
Context Assembler
Combine files and folders into one LLM-ready context block with XML tags, a project tree, ignore filters and a token estimate — like repomix or files-to-prompt, in your browser.
Prompt Template Builder
Write reusable prompt templates with {{variables}}, auto-fill the values, and copy the compiled prompt. Save your library of prompts locally — no AI calls, everything in your browser.
RAG Text Chunker
Split Markdown or plain text into LLM-friendly chunks by headings, words or characters with configurable overlap and metadata. Prep documents for RAG — all in your browser.
Token Cost Calculator
Compare LLM API costs across models with cache, batch, reasoning and traffic simulation — count tokens with a real tokenizer, refresh prices live, and export CSV/JSON/Markdown
