Regular price after launch: $6/mo or $50/yr.
How pricing works. F³ is free to view, sign and annotate PDFs — always. During launch, the first 1,000 founding members get a key that unlocks every AI feature free for a year — no card, just an email. Prefer to never think about it again? The founding $10 lifetime unlock is there too. After launch (or after your founding year ends), the AI is a subscription — $6/mo or $50/yr. Founders keep whatever they claimed: free-year keys run their full year, and lifetime licenses are for good.
