This site is the portfolio.
Everything below was built and is maintained by the person who teaches the courses. The tools are free; the engineering behind them is what you would be hiring — or learning.
231 tools
Built, maintained and kept honest. Fourteen were retired rather than left returning fabricated output.
Agent-native
An MCP endpoint, llms.txt, signed bot auth and .well-known manifests — live, not planned.
Guarded copy
Five scripts run before every deploy. One fails the build if a page claims a button it does not have.
Five case studies
A real-time voice AI platform, computer vision, a recommender, a forecaster and this site — four with live demos.
Admissions open
Five courses, one teacher
From AI for marketers through to production AI engineering with RAG and agents. Each one ends with something you built and can show someone.

About NKable
What is NKable?
NKable is an AI training and engineering studio run by Nishi Kant Chandra, offering live online AI courses for Indian professionals, custom AI systems — chatbots, agents and RAG applications — and 231 free browser-based tools.
Are the tools really free?
Yes. All 231 of them, with no account and no trial. Most run entirely in your browser and upload nothing; the few that use the server say so on the page.
Who is behind NKable?
Nishi Kant Chandra — an AI engineer and data analytics professional working between New Delhi and Moscow, who built and maintains everything on this site and teaches the courses himself.
Do you teach and take client work at the same time?
Yes, and deliberately. The client work keeps the teaching current, and the teaching forces the client work to be explainable. Capacity is limited by one person doing both, which is why cohorts are small and projects are fixed-scope.
Where are the courses run?
Live and online, across India, on Indian Standard Time. Courses run 2–3 months and cost between ₹7,999 – ₹14,999.
What kind of AI projects do you take on?
Chatbots grounded in a client's own content, agents and workflow automation, retrieval-augmented systems over private documents, custom AI applications, and analytics work. Technical SEO, AI search visibility, WordPress recovery and web development sit alongside those.
Not sure which of these you need?
Send one message describing what you are trying to do. You will get a straight answer about whether that is a course, a project, or neither — including when the honest answer is neither.
