No credit card required
You shouldn’t need a subscription to sign a PDF.
Most e-signature tools charge $25–50/month whether you send one document or a hundred. You’re paying for a seat you barely use. You’re locked into annual contracts for a feature that should be simple.
And when you finally need to send something? The interface fights you. Drag fields here, configure workflows there, watch a tutorial first.
Signing a document should take two minutes, not twenty.
Upload. Prepare. Send. Under two minutes.
Upload your document
Drop a PDF, Word doc, or image. InkSeal’s AI detects signature, date, and initial fields automatically.
Review and adjust
Fields are placed for you. Move them, add signers, or leave it as-is. You’re in control.
Send
Your signers get a secure link. They click, sign, done. No account needed on their end.
Built for people who hate paying for software they barely use.
Pay per envelope
Buy credits when you need them. Use them whenever. They never expire. Starting at $1/envelope.
AI field detection
Our AI reads your document and places signature fields automatically. Skip the tedious drag-and-drop.
