This blog post explains why an AI assistant may respond that it cannot access a specific URL and asks you to paste the article text instead.
Drawing on three decades of experience in scientific communication and AI-assisted workflows, I outline the technical and practical reasons for that limitation and provide clear, actionable guidance on how to share content for summarization, analysis, or rewriting.
Why AI assistants can’t open arbitrary web pages
There are several technical and policy reasons an AI will ask you to paste content rather than follow a link.
From a system-design perspective, many AI deployments run in controlled environments without web-browsing capabilities to protect privacy, reduce security risks, and ensure consistent behavior.
Users should understand this is intentional: it preserves data confidentiality and avoids the unpredictability of fetching dynamic or paywalled content.
It also keeps the assistant’s outputs reproducible, since the model only uses the text you provide as input.
Common constraints and safeguards
Connectivity limits, content licensing, and privacy are the top reasons for this constraint.
In practice, these constraints mean the assistant depends on user-supplied text to perform tasks such as summarization, extraction, translation, or rewriting.
How to prepare the content you paste
To get the best results quickly, structure your input so the assistant can act on it without follow-up clarification.
Clear, well-formatted pasted text reduces ambiguity and speeds up the task.
Here are practical suggestions to ensure efficient, accurate outcomes:
Example prompts that work well
Providing a concise instruction after the pasted text helps the assistant produce exactly what you need.
For example: “Please summarize the pasted article into 10 clear, concise sentences including the main findings and any numerical results.”
This tells the model both the format and the scope.
Tips for long documents and multimedia
Large reports or pages with images require a little extra effort.
If the document exceeds the model’s input limits, break it into sections and request chunked summaries that can be combined into a final synthesis.
For images, captions, or tables, paste the textual description or transcribe key values.
If you need extraction of data points, label them clearly so the assistant can produce structured output (for example: “Extract all dates and numeric values”).
Working with sensitive or proprietary material
When handling proprietary or sensitive content, consider whether anonymization or summarizing at a high level would suffice.
If sharing is necessary, follow your organization’s policies on data handling and retention.
These policies often dictate what can be pasted into external tools.
