Pro Tip
Combine this tool with our API Response Mocker to create fully functional, data-rich prototypes in seconds. Your generated JSONL can be directly imported into local LLM tuning pipelines.
Don't Just Generate.
Validate & Refine.
Most generators give you raw text. Our Browser-based Synthetic Data Forge provides a laboratory. Merge archives, scrub PII locally, and generate RAG test cases from URLs in real-time.
Multi-CSV Merge
Drag and drop multiple datasets from different archives. We automatically unify schemas and deduplicate rows for a clean master view.
Semantic Topology
Visual 2D mapping of your dataset. Identify "blind spots" where your model lacks coverage and spot repetitive clusters instantly.
Local PII Scrubber
Enterprise-grade PII scrubber for AI training. Securely detect and mask sensitive data locally before using it for synthetic training data.
Master The Factory
Architect & Configure
Define your agent's persona. Use our dynamic context engine to inject variables into your system prompt.
Forge Data
Initiate parallel production runs. Generate hundreds of unique user interactions based on your logic topology.
Quality Audit
Audit your dataset for diversity and privacy. Prune low-quality rows or repetitive clusters instantly.
Export & Deploy
One-click export to JSONL or CSV. Formatted specifically for Mistral, Llama 3, or custom training pipelines.

Frequently Asked Questions
Is the data really free?
Yes, the tool is free. You only pay for your own Gemini/OpenAI API usage.
How does Fidelity Scoring work?
We analyze the statistical fingerprint (vocab, length, sentiment) of your uploaded logs and compare it to the synthetic output.
Is my data private?
100%. All processing happens in your browser. We don't have a database, so we literally cannot steal your data.
Can I export for Llama 3?
Yes. We support direct JSONL export formatted specifically for OpenAI, Llama 3 Instruct, and Claude.
