Train AI That Knows Your Business
The only Windows desktop app that lets you fine-tune AI models without writing a single line of code. Choose from 2.1 million+ Hugging Face models, train on your PDFs, documents, websites, or entire GitHub repositories, and export production-ready AI that runs anywhere.
100% private. Your data never leaves your computer.
Built for industries where data privacy is non-negotiable:
Everything You Need to Train Custom AI
Professional-grade LLM fine-tuning in a desktop application. No command line, no cloud dependencies, no data sharing. Just powerful AI training on your terms.
No Coding Required
Complete graphical interface for the entire workflow. Upload documents, configure training, export models - all point-and-click. No Python, no command line, no ML degree needed.
100% Private & Local
Your documents never leave your computer. Train on confidential legal briefs, medical records, financial data, or proprietary research. Air-gapped capable for maximum security.
2.1 Million+ Models
Access the entire Hugging Face Hub directly from the app. Fine-tune Llama, Mistral, Qwen, Gemma, DeepSeek, and more. Search, filter, and download with one click.
2-3x Faster Training
Built-in Unsloth acceleration uses optimized Triton kernels to cut training time in half. What takes 8 hours elsewhere takes 3-4 hours with FTS Pro.
Run Anywhere
Train on CPU-only for lightweight models, leverage your NVIDIA GPU locally, or burst to cloud GPUs (RunPod, Vast.ai) for larger models. Mix and match based on your needs and budget.
Train on Any Content
Drop in PDFs, Word docs, web URLs, or entire GitHub repositories. Our Content Learning pipeline extracts text, chunks intelligently, and generates training data automatically. Build a reusable content library for future training runs.
Advanced Capabilities
Professional features typically found only in enterprise ML platforms or complex CLI tools.
Chat & Test Your Model
Built-in inference chat lets you test your trained model immediately. Ask questions, evaluate responses, and validate quality before export - all within the app.
5 Training Methods
SFT, DPO, ORPO, KTO, and GRPO (DeepSeek R1 style). Choose the right method for instruction-following, preference alignment, or reasoning enhancement.
Vision-Language Models
Train multimodal AI that understands images. Support for Qwen2-VL, LLaVA-NeXT, InternVL3, Pixtral, and PaliGemma architectures.
Mixture of Experts
Fine-tune MoE models like Mixtral, DeepSeek-MoE, and Qwen-MoE. Select specific experts, train routers, and configure load balancing.
Function Calling
Train models to use tools and APIs. Support for xLAM, OpenAI, Hermes, Glaive, and Gorilla function calling formats.
Advanced Model Merging
Combine models using TIES, DARE, SLERP, and Linear methods via MergeKit. Create specialized models from multiple fine-tunes.
LLM-as-a-Judge
Evaluate model quality using GPT-4, Claude, or local models as judges. Automated quality assessment with customizable criteria.
Safety Guardrails
Scan datasets and evaluate outputs with Llama Guard 3 integration. Detect harmful content before and after training.
Cloud Training
Need more power? Seamlessly offload to RunPod or Vast.ai GPUs. Train on H100s or A100s when local hardware isn't enough.
Export to Any Platform
Your trained models work everywhere. Export once, deploy anywhere - from local inference to cloud production.
MLOps Ready: Integrate with Weights & Biases, MLflow, and TensorBoard for experiment tracking
How FTS Pro Compares
The only Windows-native GUI with CPU, local GPU, and cloud training options. Zero command line required.
Train Your Way
Choose the hardware that fits your needs
CPU Training
Train smaller models (≤3B parameters) without a GPU. Perfect for testing and lightweight fine-tuning.
Best for: Experimentation, small datasets, budget setups
Local GPU
Leverage your NVIDIA GPU for fast local training. QLoRA enables 70B models on consumer hardware.
Best for: Privacy-critical data, frequent training, no recurring costs
Cloud GPU
Burst to RunPod or Vast.ai for H100/A100 power. Pay only for what you use.
Best for: Large models, occasional training, maximum speed
Hybrid Mode
Prepare data locally, train on cloud, then test locally. Best of both worlds.
Best for: Enterprise workflows, large-scale projects
One Price, Unlimited Training
Early Adopter Program: Free access for beta testers
Stop paying per token. Stop wrestling with CLI tools.
Professional LLM fine-tuning with complete privacy.
