HoloChart › AI chart generator
AI Chart Generator — local, for any LLM
Most AI chart generators send your data to a cloud model. HoloChart does it the opposite way: instantly, in your browser, for any LLM's answer.
An AI chart generator turns data or an AI/LLM answer into a visual chart. HoloChart is a browser extension that does this 100% on your device — it reads the answer already on your screen from ChatGPT, Claude, Gemini, Mistral, Perplexity or a local Ollama model and renders a chart with rule-based parsing, sending nothing to any server.
What makes HoloChart different
- Local, not cloud: parsing and rendering happen in your browser — no data upload, no telemetry.
- Any LLM, one tool: works across ChatGPT, Claude, Gemini, Mistral, Perplexity — and local Ollama models that cloud tools can't reach.
- No second AI: rule-based detection of tables, JSON and comparisons — fast and private, not another model call.
- Real chart types: bar, line, scatter, pie and tables cover the vast majority of AI answers.
How to generate a chart from an AI answer
Install the free extension, open any LLM in your browser, and ask it for numbers, a table or a comparison. HoloChart detects the structured data in the reply and renders a chart in a floating panel — export it as PNG, SVG or CSV in one click.
