There is no free plan. Surfer's help centre says new accounts get a 7-day trial of its Pro plan, but you enter billing details at checkout to start it, and on day 7 it converts to whatever plan you picked and charges the card. It does not lapse quietly. Paid plans start at Discovery and step up through larger tiers, with a custom-priced Enterprise tier above that; current prices are on its Launchpad page.
Two pieces of Surfer cost nothing and want no subscription. Keyword Surfer, a browser extension Surfer's own page calls "100% free. Forever.", shows search volumes inside your normal Google results; the Chrome Web Store lists it as last updated January 2026 with around 600,000 users. The AI Humanizer rewrites a short passage with no account, and a longer one once you register without a plan — English only, as the vendor states it today.
The trial runs once: Surfer's help centre says it is for new accounts only, and a card already registered with Surfer makes you ineligible, so you cannot restart it under a new email with the same card.
Annual billing saves up to about 17%, but Surfer's Regulations say a cancelled prepaid annual subscription is not refundable, with only a proportional recalculation available on request. Monthly costs more per month and risks less.
