We are a group of students learning about artificial intelligence. Help us build a knowledge base on the history of AI. Inputs: - a photo of our pinboard: milestones our group knows - milestones.md: AI milestones that an earlier group collected Tasks: - find reliable sources for every milestone, and research further important milestones yourself - download every source and save it - read each source and extract the key facts: what? who? where? when? — and so what? - store them in a structured knowledge base as Markdown, one file per milestone, with its source and its origin: the earlier group, our group, or agent - write all errors you find in milestones.md to an Excel list - pinboard cards you cannot verify go to a list "still to check" First read everything and show me your plan. Wait for my go.

Now build a visually compelling, interactive web app "A Brief History of AI" for our group. It guides visitors through the history of AI on a timeline. - use only the knowledge base — no new facts - every entry shows what, who, where, when and so what, and links to its source - show where each entry came from: the earlier group, our group, agent - a static site (HTML, CSS, JavaScript, no build step), in English - must work on phones and on the projector; do not include the photo Show me your plan first. Wait for my go.

Add a quiz to the app, so visitors can test what they learned about the history of AI. - 50 interesting questions, based only on the knowledge base - 4 answer options per question, exactly one of them correct - the wrong options must be plausible, not silly - after each answer: right or wrong, the correct answer, and a link to the matching entry on the timeline - questions in random order, a score at the end - same design as the timeline; must work on phones Show me three example questions first. Wait for my go.

Add a guided mode to the app: a narrator tells the history of AI, and the app follows along. - write an engaging story from the milestones, based only on the knowledge base - choose a fitting narrator voice from the OpenAI text-to-speech API; the API key is in the environment variable OPENAI_API_KEY - create the audio in advance — the app itself never calls the API - while the narrator speaks, the app opens the matching milestone on the timeline by itself, no clicks needed - the user can pause, skip and leave the guided mode at any time - say in the app that the voice is AI-generated - never write the API key into the app or into any file Show me the outline of the story and the voice you chose first. Wait for my go.

Create a public GitHub repository "brief-history-of-ai" and publish the app with GitHub Pages. Give me the URL. Publish only the app, its audio and the knowledge base — not the downloaded sources, not the Excel list, not the photo. Then make a QR code for the URL and open it in the browser, so everybody in the room can scan it.
