AISignature operated as an online utility for generating handwritten-style digital signatures and transparent PNG name stamps. Aimed at freelancers, remote workers, and small businesses needing quick document execution, it allowed users to draw, type, or auto-generate signature graphics without desktop graphics software. However, like many single-purpose micro-SaaS utilities hosted on hobbyist cloud setups, it failed to sustain active maintenance or hosting renewals.
