Summary written by us from the video's transcript. The video, and everything in it, is AI Foundations's work.

Learn how to set up Claude, craft effective prompts, and use its web search, vision, artifacts, and custom instructions to automate tasks and build AI-powered workflows.

Takeaways

  • Use the GCAO framework to turn vague requests into precise, high‑quality outputs.
  • Activate web search for real‑time data and combine it with structured prompts for research tasks.
  • Leverage vision by uploading images to get actionable design feedback.
  • Create no‑code artifacts like calculators directly in Claude to prototype tools quickly.
  • Set custom instructions in your profile to give Claude consistent behavior across chats.

Getting Started and Choosing a Plan

Create an account via Apple or Google sign‑in; the free plan includes Claude Sonnet, web search, file uploads, and artifacts, which is sufficient for initial exploration. The author recommends upgrading to the $17–$20 monthly plan once you hit usage limits, as paying makes you more invested and unlocks higher‑tier models like Opus 4.6.

Navigating the Claude Interface

The main prompt bar sits in the center with a model selector (Sonnet for everyday tasks, Opus for ambitious work) and a voice mode toggle. The left sidebar holds chats, projects, and past conversations; you can star, rename, or add chats to projects for organization.

Effective Prompting with GCAO

Claude’s output quality depends on prompt detail. Use the Goal‑Context‑Action‑Output (GCAO) framework: define a clear goal, provide relevant context, specify an action, and request a concrete output format. The speaker demonstrates turning a vague query like “how do I go viral on social media?” into a structured GCAO prompt that yields targeted content angles. Iterating—asking follow‑up questions or requesting variations—further refines results.

Real‑Time Web Search

Enable web search via the plus button; keep it active for up‑to‑date, non‑hallucinated information. In a single prompt you can ask Claude to research competitors, tools, or current events, and it will browse live sources (e.g., articles, Instagram) before synthesizing an answer.

Vision: Analyzing Images

Upload screenshots or photos through the plus button; Claude can read them and give feedback. The tutorial shows a YouTube thumbnail being evaluated for click‑through rate improvements, illustrating how visual analysis can inform design decisions.

Artifacts: Building No‑Code Tools

Artifacts let Claude generate interactive outputs such as calculators, dashboards, or flashcards without coding. By describing required inputs and outputs (e.g., an ROI calculator for AI automation), Claude creates a functional mini‑app that can be published and shared instantly.

Custom Instructions for Persistent Behavior

In the profile settings you can set permanent instructions that Claude follows in every new conversation. The example adds a “pirate mode” rule where the last sentence is reversed, demonstrating how custom prompts can tailor Claude’s personality or response style across sessions.
