ChatGPT canvas now autocompletes mid-sentence as you type

Users report ChatGPT's canvas editor now suggests completions in real time as they type, collapsing the turn-based writing loop into continuous keystroke-by-keystroke predictions.

May 13, 2026

ChatGPT's canvas editor is now surfacing autocomplete suggestions in real time as users type. The interface proposes sentence completions mid-keystroke, before the user finishes their thought—a shift from the prior turn-based model where users wrote a full prompt, then ChatGPT responded. The new behavior resembles GitHub Copilot's IDE autocomplete, but applied to prose and conversational text rather than code. The feature appears to be rolling out server-side without formal announcement. Users report mixed reactions: some find live suggestions useful for drafting quickly, while others describe it as intrusive when composing without interruption.

Canvas, launched in October 2024, originally treated the document as a shared scratch pad—users would write a block, submit it, and ChatGPT would respond in a separate turn. The autocomplete layer collapses that loop into continuous flow, with predictions appearing inline as the user types. The shift mirrors trends in AI-assisted writing: Google Docs added Smart Compose in 2018, GitHub Copilot brought predictive code completion to IDEs in 2021, and Notion AI added inline suggestions in 2023. The video demonstration shows autocomplete triggering multiple times within a single sentence, suggesting the model samples at high frequency as the user types.
