A no-code service that lets a small business owner upload their customer emails, product catalog, and FAQ documents, and walks away a few hours later with a private AI assistant trained on their own data — no engineers, no API keys, no data leaving their cloud account.
small business owners (lawyers, dentists, agencies, e-commerce shops) who want a private AI that actually knows their business
- Guided 'data kitchen' that scores your uploads for training quality and tells you what to add before training
- One-click fine-tuning on cost-efficient hardware, with plain-English estimates of dollars and hours before you commit
- Deploys the resulting assistant inside a private tenant with SSO, audit logs, and a usage dashboard the owner can actually read
- Plain-language confidence flags so the assistant says 'I'm not sure, check with your accountant' instead of hallucinating
Projects like nanochat being ported to cheaper TPU hardware signal that small-scale fine-tuning is approaching $100-per-business economics — making 'train your own AI' a realistic purchase for a Main Street business owner instead of a Fortune 500 IT project.

SLM market projected to grow ($6.5B in 2024 → $20.71B by 2030 per one source) and on-prem fine-tuning economics are improving via nanochat-style projects, but OpenAI/Google keep raising the baseline and RAG-as-a-service margins will compress.The $47K Fine-Tuning Revolution: How Small Language Models Are ↗NanoChat - The best ChatGPT that $100 can buy - GitHub ↗
The RAG-on-business-data pipeline is well-understood and reusable (vector store + LLM API), but the 'no API keys / data stays in their cloud' promise adds real engineering complexity (BYO cloud, tenant isolation, secret management) beyond a simple wrapper.How to Choose a No-Code Chatbot Builder in 2026 (8 Compared) ↗Fine-Tuned Small Models Beat RAG: The 2026 Economics ↗
