Qiksy Bridge is free, so there is nothing to buy here. Everything is switched on from the first minute, the agent bridge included: no price, no trial, no key, no account. If you are holding a licence key from before, you can throw it away, and nothing you have will expire. Install or update it from the Chrome Web Store, and the page that explains it is https://qiksy.app/qa-copilot/ — there is a coffee link at the bottom of it if the thing ever saves you an afternoon.
