tailor. vs ChatGPT.
ChatGPT runs in the cloud. tailor. runs on your machine.
ChatGPT is a remarkable product, but every single prompt you send leaves your computer, hits OpenAI's servers, and is retained according to policies you don't control. For a personal "what's the capital of France" question, that's fine. For analyzing a client contract, debugging proprietary code, or writing about anything sensitive, it isn't. tailor. is the closest thing to ChatGPT's workflow that runs entirely on your own hardware.
| Capability | ChatGPT (Plus) | tailor. |
|---|---|---|
| Where inference runs | OpenAI's servers | Your machine |
| Data leaves your device | Every prompt, every file | Never |
| Works offline | No | Yes (after model download) |
| Model choice | GPT-4o, GPT-4 Turbo, o-series | Llama, Mistral, Qwen, DeepSeek, 1000s more (any open GGUF) |
| Agentic chat | Yes | Yes |
| Document chat / file analysis | Yes | Yes , every file type, multimodal |
| Image generation | DALL-E 3 (cloud) | Stable Diffusion (local) |
| Code execution | Sandboxed Python (cloud) | Sandboxed code on your machine |
| Audio transcription | Whisper API (cloud) | Whisper (local, with speaker labels) |
| Fine-tune on your data | Limited, via OpenAI's training pipeline | Local LoRA on your hardware (via llama-finetune or mlx_lm.lora) , your data never leaves |
| Price | $20/month | $11/month |
| Vendor lock-in | Tied to OpenAI's API and models | Models are open files; portable |
| Censorship / refusals | Tuned to OpenAI's policy | Pick a model with the alignment you prefer |
When ChatGPT is still better
Frontier capability. On the hardest reasoning tasks, the very best closed models (GPT-4o, Claude 3.5 Sonnet) are still ahead of what you can run on a laptop. If you're doing complex multi-step research where raw intelligence matters more than anything else, ChatGPT is still the higher ceiling. tailor. closes the gap on most everyday work, but the very top of the model leaderboard is a cloud-only ceiling.
When tailor. is obviously the right choice
Anything you wouldn't want OpenAI to read. Client contracts, codebases under NDA, medical or legal context, business strategy, financial planning, personal writing, anything covered by HIPAA or GDPR. Anything you want to keep working on a flight, in a SCIF, on a yacht, or in a place where the internet isn't reliable. Anything you want to fine-tune on your own writing or your own data without uploading it.
What about the price difference?
ChatGPT Plus is $20/month. tailor. is $11/month. That's not the main reason to switch , privacy is , but over a year that's $108 you keep. There are no per-token charges, no rate limits, no daily message caps.
