Custom AI/ML Development
Custom AI/ML development is building machine-learning and AI systems around your specific data and decisions — pricing, prediction, classification, LLM applications — and shipping them to production, not a notebook. Lets Automation, Surat, India, builds them in Python on FastAPI and Next.js. Fixed scope, fixed price, you own the code and the models.
Sound familiar?
- Decisions that depend on data — pricing, stock, scheduling — are still made by gut feel because the data is spread across systems.
- Someone built a model in a notebook once; it never reached production.
- Off-the-shelf AI products don't fit your process and can't see your data.
- You have years of records and no way to learn from them.
- An AI pilot worked in a demo and nobody knew how to run it day to day.
What we build
Pricing and recommendation engines
- What it is:
- Models that suggest prices, offers or next actions from your history and live demand, with a person approving before anything changes.
- What it replaces:
- Pricing by spreadsheet and instinct.
- What changes:
- Suggestions with reasons, approved by a human, with an audit trail.
Prediction and classification
- What it is:
- Demand, no-show, lead-quality or document-classification models trained on your own data.
- What it replaces:
- Treating every customer, order or document the same.
- What changes:
- Effort goes where the model says it matters.
LLM applications
- What it is:
- Custom applications on large language models — extraction, summarisation, drafting, agents — integrated into your systems.
- What it replaces:
- Manual reading, typing and summarising.
- What changes:
- Minutes of review instead of hours of work.
Production deployment
- What it is:
- APIs, monitoring, retraining and a proper frontend, so the model is a system your team uses, not an experiment.
- What it replaces:
- Notebooks and one-off scripts.
- What changes:
- The model runs every day, and you can see it working.

Written plan within 7 days — whether a model makes sense yet, or a simpler automation gets you there faster.
- 3
We prepare the data, build and evaluate the model against your real history.
- 4
Demo every two weeks; you see predictions alongside what actually happened.
- 5
Production deployment with monitoring and a human-approval step where decisions matter, then 90 days of support.

Common questions
Do we need a lot of clean data to start?
Less than people think, but it has to be real. In the free call we look at what you actually have — ERP exports, spreadsheets, call logs — and tell you honestly whether a model makes sense yet. If a simpler rules-based automation will get you there faster, the written plan says so.
How much does a custom AI/ML system cost?
We don't publish fixed prices for a custom AI/ML system, because the price depends on scope — how many channels, systems and features you want included changes what we build. What we do fix is the quote: after a free 30-minute call you get a written plan with a fixed scope, fixed price and fixed timeline before any code is written. No hourly billing, and if you add to the scope later, that's quoted separately and in writing.
How long does a custom AI/ML system take to build?
We build in 4–8 week sprints with a working demo every two weeks. Most clients see their first automation live within about 6 weeks. The written plan you receive after the free call includes a fixed timeline for your specific scope.
Do I own the code and data?
Yes. You own the code, the server and the data. We build on tools like n8n and open APIs so there's no licence that scales with your usage, and there's no 12-month lock-in — you can take the system in-house whenever you want, or keep us on for support.
Do you work with businesses outside Surat?
Yes. We're based in Surat, Gujarat, and work with businesses across India and remotely with clients abroad. Scoping, the fortnightly demos and support all run over calls and WhatsApp, so location doesn't change how we work.
