Eyeball is a GitHub Copilot CLI plugin with a deceptively simple idea: instead of trusting the AI to accurately summarize documents, it captures screenshots of the actual source material and embeds them alongside the AI's claims in the output report. If the model says "Section 10 requires mutual indemnification," the report shows that exact section highlighted in yellow directly below the claim. The underlying insight is sharp — screenshots cannot be hallucinated. Text can be subtly reworded, paraphrased incorrectly, or synthesized from nowhere. But a screenshot is a literal capture of the source. Built for legal review, compliance analysis, financial due diligence, and any domain where the stakes of an AI error are high. Built by indie developer dvelton, it handles PDFs, Word documents, and web pages. MIT licensed, free to use. Surfaced on Hacker News Show HN today, where it sparked an active discussion about AI verification and the underrated value of visual evidence in AI-assisted analysis workflows.

marimo-pair is an open-source extension for marimo reactive notebooks that lets you drop AI agents directly into live, running notebook sessions. Unlike traditional AI coding assistants that only see static code, these agents can execute cells, inspect in-memory variables, read dataframes, manipulate UI components, and iterate on your actual live state — not a static snapshot. The tool plugs into Claude Code via a marketplace plugin and supports any agent implementing the Agent Skills standard. An agent that can see and run your notebook opens up genuinely new workflows: "explore this dataframe and tell me what's anomalous," "run this hypothesis test on the data already in memory," or "generate a chart for each of these 12 conditions." It's the difference between an assistant that reads your code and one that works alongside you in your actual environment. Marimo itself is already a compelling React-based replacement for Jupyter — every cell tracks its dependencies so the notebook is always consistent. marimo-pair makes that reactive model collaborative with AI, enabling a new style of human-AI pair programming where the agent shares your full computational context.
Reviewer scorecard
“This is one of those ideas that makes you think 'why isn't every AI analysis tool doing this?' The implementation is simple — capture screenshots of the source during analysis — but the trust it builds in the output is enormous. I'd use this immediately for any contract or regulatory review workflow.”
“The gap between 'AI sees your code' and 'AI runs in your environment with live data' is enormous for data science work. I've wasted hours explaining context to LLMs that could have just looked at the dataframe. This closes that loop completely.”
“Screenshots prove the source exists but don't verify the AI's interpretation of it is correct. A model can still misread highlighted text or draw wrong conclusions. Also, PDF-to-screenshot pipelines get messy with scanned documents, multi-column layouts, and complex tables — exactly the docs where hallucinations are most likely.”
“Giving an agent the ability to execute arbitrary cells in a live environment with production data is a security nightmare waiting to happen. The v0.0.11 version flag means this is still early — wait until there's a proper permissions/sandbox model before trusting it with real data.”
“Eyeball points toward a future of verifiable AI outputs — not just 'the model said this' but 'the model said this, here's the evidence, here's the reasoning chain.' Legal AI adoption hinges on explainability, and embedded source screenshots are a practical step toward outputs that hold up under professional scrutiny.”
“Reactive notebooks with agent context sharing is the architecture for AI-native scientific computing. This isn't just a tool — it's a prototype for how researchers will work with AI in 2027: not prompting from outside, but collaborating inside the live computational environment.”
“For research, journalism, and content work where you're citing sources, this is a game-changer. The ability to produce a report where every claim is visually anchored to the source makes the output publishable rather than just useful. The design of the output document matters — would love to see more control over the visual layout.”
“For creative data analysis and visualization work, being able to tell an agent 'make this chart more readable' while it can actually see the rendered output is a quantum leap over copy-pasting code. Marimo's reactive model makes iterating on designs feel instant.”
