Token Forecaster puts a range on an LLM reply before you press Enter: the usual length, and a worst case that held for 90.6% of 4,146 unseen calls. While the reply streams, it shows whether it is running long. It only watches and never changes the request. Learns from your local history. Open source, MIT.
