        "Google announced Canvas on March 18, 2025 as an interactive space within Gemini for creating, refining and sharing documents or code. The post said a person could select Canvas in the prompt bar, write or edit a document or code, and see changes appear in real time. It described tools for changing a selected passage or a whole draft's tone, length and formatting, then exporting the result to Google Docs. The same dated page said Canvas was rolling out globally that day for Gemini and Gemini Advanced subscribers in all languages where Gemini Apps was available. This provides an event-specific availability statement. It does not establish access for every Google account, a later product tier, a particular country, or a specific document. The assistant feature was a shared drafting surface, not an endorsement of every revision generated within it."

      "paragraphs": [
        "The launch described Canvas as a place to turn coding ideas into initial web apps, Python scripts, games, simulations and other interactive applications. Google said a person could ask Gemini to generate and preview HTML or React code, make a request such as adding fields or calls to action, then see an updated visual representation. That chain has a clear practical value: it lets a person compare a requested change with a rendered prototype before sharing it. But previewing a form does not validate server behavior, authentication, accessibility, security, performance, data retention or deployment configuration. The announcement did not claim otherwise. It described initial working versions and iterative edits, which is a smaller and more defensible capability. A developer still had to inspect the source, exercise real inputs and failures, and verify any production integration. The public release is evidence of a tool surface, not evidence that a generated app passed engineering review."

      "heading": "Document refinement and code generation had different review obligations",
      "paragraphs": [
        "Canvas combined two kinds of work that are often treated too casually as one. For prose, Google's release described drafts, targeted changes and export to Docs; a reviewer can check claims, voice, citations and version intent. For code, it described generation, debugging, explanation and prototype previews; a reviewer must additionally test behavior and inspect dependencies, permissions and data paths. The common Canvas interface does not erase those differences. A concise rewrite can still change meaning, and a visual prototype can still conceal an insecure or broken implementation. The announcement's collaboration language should therefore be read as a statement about the human-tool iteration loop. It does not prove that another editor agreed with a revision, that a Google Docs export preserved a chosen governance record, or that an AI-generated result was suitable for publication. Retaining the prompt, source edits and human acceptance remains useful when the work has consequences."

      "heading": "Current help adds operating and sharing details after the launch",
      "paragraphs": [
        "Google's current Canvas help guide says changes to apps and docs are auto-saved, identifies code editing, preview console and recent-change views, and describes direct selection-based edits. It also says a shareable public app link can let anyone with the link view and edit data associated with the app, and lists capabilities such as data sharing, Gemini-powered features and saving across sessions or devices. Those present-day details matter because a generated prototype can acquire persistence and a public audience through later choices. They are not evidence that the March 2025 version had those exact controls or behavior. The dated source establishes the initial document, code and preview feature; the current guide identifies checks a user should make before sharing now. A person should review the app information and access model at the time of sharing rather than infer a security or privacy posture from Canvas's original launch announcement."
