HoloChart › HoloChart vs Claude Artifacts
HoloChart vs Claude Artifacts
Both turn data into charts. The difference is where it happens and which model you're locked to.
Claude Artifacts is Anthropic's live-preview feature: when Claude writes React/HTML/SVG code, it renders an interactive chart (usually via the Recharts/D3 library) in a panel beside the chat, running in Anthropic's cloud environment. It is excellent — but it only works inside Claude, and your data is processed on Anthropic's servers.
HoloChart is a browser extension that visualizes the answer of any LLM — ChatGPT, Claude, Gemini, Mistral, Perplexity, or a local Ollama model — entirely on your device. It reads the answer already on your screen with rule-based parsing (no second AI call), renders a chart in a floating panel, and sends nothing to any server.
Side by side
| Capability | HoloChart | Claude Artifacts |
|---|---|---|
| Runs where | ✓ On your device (browser) | Anthropic cloud |
| Works with | ✓ Any LLM incl. local Ollama | ✕ Claude only |
| Sends your data to a server | ✓ Never | Yes (to Anthropic) |
| Second AI call to chart | ✓ No — rule-based | Yes (Claude generates code) |
| Chart quality / interactivity | Good, SVG, on-device | ✓ Excellent (Recharts/D3) |
| Works offline | ✓ Yes | ✕ No |
When Claude Artifacts is the better choice
If you're already working inside Claude, want highly polished interactive React dashboards, and are comfortable with your data being processed in Anthropic's cloud, Artifacts produces beautiful results and iterates conversationally.
When HoloChart is the better choice
If you switch between several LLMs, use a local model via Ollama, or simply don't want your numbers leaving your machine, HoloChart gives you one consistent chart layer across all of them — no re-uploading data, no vendor lock-in, no telemetry.
Frequently asked
- Does HoloChart replace Claude Artifacts?
- No. Artifacts builds interactive apps and dashboards inside Claude. HoloChart is a lightweight, local visual layer that charts the answer of any LLM — including Claude — without sending data anywhere.
- Can HoloChart chart a Claude answer?
- Yes. Open Claude in your browser, and HoloChart detects tables, JSON and comparisons in Claude's reply and renders a chart locally, with no extra AI call.
- Does my data reach a server with HoloChart?
- No. Parsing and rendering happen entirely in your browser. Not even the free-tier share watermark contains tracking.
- Does HoloChart work with local Ollama models?
- Yes — this is a key difference. Cloud artifact tools cannot reach a local model; HoloChart charts an Ollama answer the same way it charts a cloud LLM.
