Most 'free' invoice generators force a signup before the first download. I tested 6 of them on a real freelance scenario — a 20-hour web dev invoice with tax, discount, and bank wire details — to see which ones actually work. Only two didn't want my email.
One Vercel employee clicked "Allow All" on a Context.ai OAuth prompt. A month later, half of Web3 rotated their deployment keys. Here''s the chain, what was and wasn''t leaked, and the env-var toggle you should have flipped yesterday.
Grammarly's free tier locks half the good features behind a signup wall. I tested 5 free AI proofreaders on the same buggy paragraph to see which actually catches errors — and which ones are just lead magnets wearing a proofreader costume.
