 "title": "Ask weather, unit and recipe questions without an LLM",
 "page_title": "How to ask weather, unit and recipe questions without an LLM with Jev Chat",
 "summary": "Run the chat bar locally and get weather, unit conversions and recipes from tools, not model text.",
 "who": "A person who wants quick everyday answers from a chat bar and does not want a language model to make up numbers or facts.",
 "problem": "Chatbots can state a temperature, conversion or recipe step that no source returned. Users need answers where every value comes from a tool.",
 "outcome": "A running local chat app that answers weather, unit and recipe questions, with every value on screen typed by the user or returned by a tool.",
 "steps": [
  "Run `corepack enable` to pick up the pinned pnpm version.",
  "Run `pnpm install` in the repo folder.",
  "Run `cp .env.example .env` and set TYPESAFE_API_KEY in the new file.",
  "Run `pnpm dev`, then open http://localhost:5173 in a browser on the same machine.",
  "Type \"350F in celsius\" and \"What's the weather in Denver tomorrow?\" and check that each reply cites tool data."
 ],
 "agent_prompt": "In the jev-chat repo, copy .env.example to .env, set TYPESAFE_API_KEY to <typesafe-key>, and run pnpm dev. Send the message \"350F in celsius\" to the chat at http://localhost:5173 and report the reply. Verify that the reply value came from the units tool and not from model text.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The app only works in English, and every message gets an error reply until a paid TypeSafe key is set.",
 "category": "Personal productivity",
 "tags": [
  "Personal productivity"
 ],
 "lang": "typescript",
 "requirements": [
  "Node 24 or later and pnpm 11 (run corepack enable to pick up the pinned version)",
  "A TypeSafe API key in TYPESAFE_API_KEY, since Jev is a paid API and the app shows error replies without it",
  "A terminal and a local browser on the same machine, because the API only listens on 127.0.0.1"
