LastLayer pitches a three-step flow — 'Drop your files. Train your AI. Talk to an expert.' You upload a batch of documents (the homepage demo uses a trading rulebook), the platform runs a training pass on them, and you then ask questions and get answers grounded in that material. The site describes it as 'Real AI training directly on your documents' and 'Instant Knowledge Flow: from raw files to AI specialist in 3 steps', with a visual pipeline of Documents, Training, Question, Answer. The homepage pricing section lists a Free plan ($0, 100 credits on sign-up, up to 50K characters) and paid tiers of $10, $25 and $99 a month (Starter, Basic and Pro) metered in credits, with no annual billing. The app itself lives at sys.lastlayer.dev behind a Google or email sign-in.
People or small teams who have a body of documents and want a question-answering assistant grounded specifically in them.
Turning a rulebook, manual or research set into an askable knowledge base; domain Q&A over your own uploaded files; exploring a dataset conversationally without building a RAG stack.

The pitch is concrete and demoable — a named 3-step flow and a worked example — rather than a generic 'chat with your docs' claim.
No public pricing was reachable, the 'real neural network training' claim is not substantiated on the page, and the product is gated behind a sign-in so it cannot be tried without an account.
