AI Chatbot Emulator
Build and test a knowledge-base chatbot right in the browser. Paste or upload your FAQ / docs as Q&A pairs, define a persona + system prompt, set tone and guardrails, then chat with the bot using a pure-JS retrieval engine (TF-IDF + Jaccard + Levenshtein fuzzy matching) that cites which KB chunk was used. Intent detection (greeting, farewell, thanks, question), configurable fallback rules, confidence scoring, KB chunking, KB validation with warnings, multiple saved bots (localStorage), transcript export (text / Markdown / JSON), shareable URL with full bot config, JSON config import / export, optional BYO-key LLM enhancement (OpenAI / Anthropic). 100% client-side — your KB never leaves the browser unless you explicitly enable LLM polish.
