What açai Sign Does
Built for the whole
signing lifecycle.
From the moment you upload a document to the day your auditor asks for the trail, every step is handled with intelligence, care, and court-ready compliance.
Reusable templates
Turn your offer letter, NDA, or vendor agreement into a one-minute send. Merge fields auto-populate per recipient.
Bulk send via CSV
Upload a CSV of recipients and dispatch hundreds of personalised contracts in a single action - each with its own merge values.
In-app document editor
Make last-minute edits to a Word file without leaving the app. Smart field placement controls font, size, and alignment.
Tamper-evident sealed PDFs
Every completed envelope ships with a full chain-of-custody audit: who signed, when, from where, on what device.
Full envelope lifecycle
Reminders, expiry alerts, decline + void flows, resend invites, duplicate envelopes, sub-folders, Inbox & Outbox views, reports.
Six steps, signed and sealed.
From the first upload to the audit-ready final PDF, every envelope moves through a workflow that's fast, secure, and legally defensible.

Step 3 of 6 · Send
One signer, a hundred, or a whole CSV.
Single send, sequential signing, or bulk dispatch from a CSV — every recipient gets a personalised envelope with merge fields filled in automatically.
Step 4 of 6 · Sign
OTP-protected access, on any device.
Signers verify via OTP, then sign with a signature pad, library upload, or saved signature. Sign-yourself flow works for self-attested documents too.
Step 5 of 6 · Track
Reminders, expiry alerts, void & resend.
Stay on top of every envelope. Automatic reminders, expiry alerts, decline + void flows, resend invites, duplicate envelopes — all from the Outbox.
Step 6 of 6 · Seal
Tamper-evident PDF + court-ready audit.
Every completed envelope ships sealed with a chain-of-custody audit: who signed, when, from where, on what device — independently verifiable via RFC 3161 timestamps.
Built on the standards your auditor already trusts.
Aadhaar eSign
UIDAI-backed signing for any Indian citizen via Aadhaar + OTP. IT Act 2000 §3A compliant out of the box.
eMudhra DSC
Class 2 / Class 3 Digital Signature Certificates for high-value contracts, board resolutions, and MCA / GST / Income-Tax filings.
DigiLocker
Push completed contracts straight to the signer's DigiLocker so they always have a verified, government-issued copy.
GeM (Government e-Marketplace)
Vendor-side signing for tender responses on India's largest public procurement platform.
RFC 3161 Timestamps
Every sealed PDF carries a trusted third-party timestamp so signature time is independently verifiable in court.
Open API + Webhooks
Drop Sign into your existing HRIS, ERP, CRM, or vendor portal in a day. Event webhooks fire the instant a document completes.
Aadhaar eSign, eMudhra DSC, and DigiLocker are wired in for India. ESIGN Act + UETA (US), eIDAS-aligned signature tiers (EU & UK), and Singapore / Australia / UAE compliance are on the rolling roadmap — region-aware signing surfaces switch the right framework based on the recipient's jurisdiction.
