SignYu Reviews & Product Details

SignYu (formerly SignSetu) is an Aadhaar eSign platform for India. Upload a PDF, add up to 6 signers, and each signer signs with an Aadhaar OTP on their phone. Signatures are issued through eMudhra, a licensed Certifying Authority, and are valid electronic signatures under Section 3A of the Information Technology Act, 2000. There is no subscription for the web app. You buy signature credits and pay per signature: ₹15 per signature on packs of 10 or more (GST included), with smaller packs available. Signers do not need an account, a USB token, or any software. For developers, the SignYu API lets you add Aadhaar eSign to your own product, with HMAC-signed webhooks, an OpenAPI spec, a Postman collection and official SDKs for Node.js and Python. API access is ₹999 per month (GST included) with a 3-day free trial, and signatures use the same credits as the web app. When signing finishes, every party receives the signed PDF, and you can download a Signature Completion Certificate with a chronological audit trail of signing events. SignYu runs its servers and document storage in India and never stores Aadhaar numbers.
