Eyeball is an indie tool that fights AI hallucination in document analysis by embedding inline screenshots of the actual source passages alongside each AI-generated claim. When you analyze a PDF or document with Eyeball, the output is a Word doc where every statement has a highlighted screenshot of the precise text it came from — because screenshots are harder to hallucinate than quotes. The tool emerged from a simple observation: AI systems routinely fabricate citations and misquote sources, and quote-only verification still requires humans to manually hunt down the original text. Eyeball short-circuits that by attaching the visual evidence directly to each claim in the output document. Legal, compliance, and research reviewers can audit AI outputs at a glance rather than cross-referencing. Built in Python, Apache 2.0 licensed, launched as a Show HN six days ago and gaining traction. The approach is low-tech by design — no vector embeddings, no proprietary API calls — just precise text highlighting, screenshot capture, and Word document assembly. The simplicity is the point: verifiable AI outputs shouldn't require a research budget.

GitNexus is a zero-server, client-side code intelligence engine that runs entirely in your browser. Drop in a GitHub repo URL or ZIP file, and it builds an interactive knowledge graph that maps every function, import, class inheritance, and execution flow — no backend required, no code ever leaves your machine. It uses Tree-sitter WASM for AST parsing, LadybugDB for in-browser graph storage, and HuggingFace transformers.js for fully local embeddings. On top of the graph sits a built-in Graph RAG agent you can query in plain English. Ask "where does authentication happen?" or "what calls this function across the codebase?" and get precise answers backed by structural graph traversal rather than fuzzy keyword search. Eight languages are supported out of the box: TypeScript, JavaScript, Python, Java, Go, Rust, PHP, and Ruby. GitNexus also ships an MCP server, letting Claude Code and Cursor tap directly into the live knowledge graph for full codebase structural awareness mid-session. It hit #1 on GitHub trending in April 2026 with 28k+ stars — a clear signal that developers are starving for AI agent context tooling that doesn't send their proprietary code to a third-party cloud.
Reviewer scorecard
“This is the kind of clever, unglamorous tool that actually solves a real problem. The insight that screenshots are harder to hallucinate than quotes is simple but profound. Drop this into any pipeline that serves legal or compliance users immediately.”
“This is the missing layer between your codebase and your AI agents. The MCP integration means Claude Code can now actually understand your repo structure instead of guessing from file names. The privacy-first, zero-server approach makes it the only option I'd trust with client code.”
“Screenshots of source text don't prevent the underlying problem — an AI can still misinterpret or misconstrue what the screenshot says. It adds friction to the review process without fixing the root cause. Useful for basic verification but don't mistake it for a hallucination solution.”
“Running complex AST parsing and embedding generation in the browser via WASM sounds great until you try it on a 500K-line monorepo — the browser tab will struggle badly with memory limits. There's no authentication, no team sharing, and the graph state evaporates on refresh. Build the MCP server into a proper local daemon first, then we'll talk.”
“Provenance-by-design is going to be mandatory for AI in regulated industries. Eyeball's approach — baking visual evidence into every claim — points toward a future where AI outputs are self-auditing. This is an indie tool today; it's a compliance standard in three years.”
“Graph-native code understanding is the inevitable next step past flat file retrieval. When AI agents can reason about call graphs and dependency chains instead of just token proximity, whole new classes of autonomous refactoring become possible. GitNexus is an early but crucial proof of that future.”
“For editorial and research work, knowing exactly where an AI got its information is table stakes. Eyeball makes that process visual and immediate — that's a huge quality-of-life improvement for anyone who fact-checks AI-generated research.”
“The interactive knowledge graph visualization alone is worth it for onboarding new teammates. I've never been able to explain a legacy codebase this fast — you can literally point at a node and say 'this is the problem.' Pair it with an AI agent and it becomes a live explainer.”
