What Fynl.io is, and where it fits
Fynl.io is one portal a small business runs itself on, instead of five subscriptions that do not talk to each other.
The AI runs on your own Claude or ChatGPT API key. You keep the key, you pay the model provider directly, and there is no markup on top of it. There is no SMS or phone calling yet, and we would rather say so than let you find out later.
