Upload a textbook, lecture notes, or paste any text. SmartTrain AI uses RAG (Retrieval-Augmented Generation) + Logfare AI to answer questions accurately from your data, and chat naturally for general questions. Built by Sarc Education Foundation to help students understand how AI really works.
Lightweight. Modern. Mobile-first. Works on any shared hosting.
Auto-extracts text, chunks it with overlap and builds a searchable vector index.
Natural conversation, reasoning and answer composition powered by Logfare AI.
Cosine similarity over chunk embeddings retrieves the right context every time.
24h, 7d, 30d expiry. Permanent accounts available via admin approval.
Unique Access ID + Model ID. Resume any time at /chat/AX92KD.
Toggle anytime — full visibility parity in both themes.
AJAX everywhere. No heavy frameworks. Loads instantly on shared hosts.
Manage users, files, chunks, settings, requests, logs — all via AJAX.
PDF Upload → Extract → Clean → Chunk → Embed → Vector Search → Inject → AI answer.
PDF / TXT / DOC / DOCX / MD / CSV up to 15MB.
Sentence-aware chunking with overlap, plus 256-dim semantic embeddings.
Cosine similarity finds the most relevant context for your question.
Logfare AI composes a natural, accurate reply grounded in your data.
For Sarc Education Foundation students — quick, visual, and beginner-friendly.
Retrieval-Augmented Generation means the AI first retrieves relevant text from your documents, then generates an answer using that context. This makes answers grounded and accurate.
SmartTrain AI is hybrid: greetings and general chat use Logfare AI directly, while data-grounded questions trigger the RAG pipeline. This keeps replies fast for small talk and accurate for documents.
An embedding turns text into a list of numbers. Similar meanings produce similar numbers — so we can find related chunks just by comparing vectors with cosine similarity.
By default, your workspace auto-deletes after the chosen expiry (24h / 7d / 30d). Need a permanent account? Submit a request — an admin will review it.
It's free, private and takes less than a minute. No account needed.
