A free playground on Gemini with a 1M-token window and a visible token counter — the course's build bench for prompt work.

Pick this when

You have a big document to process once and don't want to spend paid tokens doing it — the trainer builds his meta prompt here for exactly that reason.

What makes it different

Visible token counter — you watch a 38k-token PDF land, which teaches context spend better than any explanation

1M context on a free account

No subscription needed to do serious one-off document work

What it does

Runs Gemini with uploaded files in a playground interface

Shows exact token consumption per attachment

Hosts the home-project contract-analysis RAG from BC1

What it does not do

Common wrong expectations

Doesn't guarantee availability on free accounts — it errored mid-demo and the trainer had to switch accounts

Doesn't replace a real assistant for daily work; it's a bench, not a workshop

Where it sits in a stack

One-off heavy-document jobs: build a meta prompt, analyse a stack of contracts, test a long-context idea before paying for it.

A sensible free bench if a task ever needs a whole transcript in one window.

For your projects

Concrete use: paste a full condensed transcript plus the extraction schema here to sanity-check an extraction without spending Fable budget.
