LT
Train AI locally or privately on your own knowledge, deepen its understanding for any domain, and deploy agents across WhatsApp, Instagram, Facebook, APIs, websites, and your workflow.
Your second brain. Privately trained. Infinitely deployable.
How It Works
Upload PDFs, documents, websites, YouTube, databases, CRM data, or any source. Your AI learns exactly what you know.
Expand context window, layer domain knowledge, run RLHF alignment. Your AI becomes an expert — not just a chatbot.
Turn your trained model into autonomous agents. Support, sales, research, personal assistant — any workflow you imagine.
Ship to WhatsApp, Instagram, Slack, your website, internal APIs — or keep it fully local on your own hardware. You choose.
For Everyone
Whether you're a solo creator, a student, a startup, or an enterprise — Langtrain gives you the same power to train, deepen, and deploy your own AI.
Train AI on your notes, research, books, and ideas. Ask it anything about your own knowledge base. Never lose context again.
Train AI on your brand voice, audience data, past content, and creative library. Generate on-brand content at scale.
Build AI agents for customer support, lead qualification, and onboarding. Ship faster. Scale cheaper. Own the intelligence.
Fine-tune models, build agents, expose OpenAI-compatible APIs, and integrate with any app. Full control, zero lock-in.
Train AI on your textbooks, lecture notes, and research papers. Get tutored by an AI that understands your exact course.
Deploy on-prem or private cloud. SOC2 compliant. Custom guardrails. Your proprietary knowledge stays inside your walls.
Knowledge Depth
Generic AI knows the public web. Langtrain lets you build AI that knows your domain, your language, your data — at institutional depth.
Trained on the public web. No access to your specific domain, your data, or your institutional knowledge.
Knows the surface. Misses your context entirely.
Fine-tuned on your specific data. Knows your domain, your language, your context at institutional depth.
Knowledge depth layers
Every piece of data you add makes your AI smarter. Unlike rented AI, your Langtrain model gets more valuable as your organization grows.
Connector Ecosystem
Deploy your trained AI across every channel your customers use — without rebuilding anything.
Your AI agent is live on WhatsApp. Responds with domain-specific knowledge, trained on your data.
Ingest from any source
Agent Ecosystem
Langtrain is a full AI operating layer — train once, then deploy specialized agents for every function in your business.
Handles support queries 24/7 with deep knowledge of your product, policies, and past resolutions. Escalates intelligently.
Engages prospects, qualifies leads, and books meetings based on your exact ICP and sales playbook.

The Transformation
Key metrics comparison
Stop renting intelligence. Build your own deeply trained AI model, deploy it as agents, and connect it everywhere — with zero vendor lock-in.
"We replaced our entire AI stack with one Langtrain model. It knows our domain better than any off-the-shelf tool — and we own it completely."
Build your own AI brain. Train it. Deepen it. Connect it. Deploy it.
