How to use ChatGPT, Claude, and Gemini's second screen features

Executive overview

Most ChatGPT, Claude, and Gemini users never open the canvas or artifacts panel sitting beside their chat. This second screen shifts AI from conversation to co-creation — producing documents, diagrams, and interactive tools.

Without it, iterative editing wastes time and degrades AI quality: each full rewrite fills the context window, making the model less capable with every pass.

The canvas and artifacts panel is where AI stops answering and starts building.

Turning the feature on

• ChatGPT: click the plus icon in chat, select Canvas under More
• Gemini: open the Settings cog, click Canvas
• Claude: no toggle — ask explicitly in your prompt to use the Artifacts feature
• All three also respond if you simply name the feature in your prompt

Why to avoid editing without canvas

• Without canvas, AI rewrites the entire document and returns it in chat — forcing you to diff the output manually
• Each full rewrite consumes context window; after 4–5 cycles the model is markedly less capable
• Canvas enables targeted edits: highlight a paragraph, ask for a change, only that section updates

Collaborative writing with AI

• Highlight a specific section and prompt inline — ChatGPT and Gemini will rewrite only that segment
• Version history lets you revert any edit the AI made
• Built-in reading level and length controls adjust formality and word count without a new prompt
• Best use case: have AI act as a persona-based editor (e.g. "review as Mark Manson") using the comment feature — it annotates the document rather than rewriting it
• ChatGPT is strongest for editor-style feedback; Gemini tends to edit directly when it should only comment
• Workflow: paste document → ask AI to load it into canvas verbatim → then prompt for comments, not changes → accept or reject each suggestion individually

Creating visuals and diagrams

• Paste a meeting transcript and ask for a flow diagram of the process discussed — useful for SOPs and client onboarding
• Use alongside long SOPs: a one-to-two-minute infographic covering 80% of the content is more likely to be read than 30 pages of text
• Gemini's canvas includes one-click creation of infographics, quizzes, flashcards, and podcast overviews from pasted notes
• Claude excels at animated data visualisations: paste a dataset or transcript, request an animation, screen-record it, embed in PowerPoint
• Animated charts are more engaging in presentations than static imports from Excel

Building quick ephemeral tools

• Canvas can produce small interactive HTML tools — calculators, configurators, checkers — that live in the browser without any setup
• Example: a commissions calculator with adjustable sliders, tier labels, and animated feedback, shared via a public link
• Claude and ChatGPT support public sharing; Gemini does not support easy external sharing
• Sharing requires setting the tool to publicly viewable unless the team has a shared account
• Build for a specific scenario, share the link, discard when no longer needed

When to reach for canvas or artifacts

• Use it when the output needs multiple rounds of refinement
• Use it when the output is visual and will be shared with others
• If neither condition applies, the standard chat window is sufficient
