Turn static PDFs into signed, completed documents.
Signum reads your PDFs, detects fields automatically, and gives you a precise editor to refine every detail. Then send, sign, collect payment, and track responses — all in one secure workspace.
From PDF to signed in three steps.
No rebuilding forms from scratch. Upload, refine, and send.
Upload your PDF
Drop in any contract, form, or agreement. Signum reads the page structure and existing fields automatically.
Refine in seconds
Auto-detect underlines and boxes, adjust field types, sizes, and assignees in the precise visual editor.
Send & track
Share a secure link, collect signatures and responses, and download the completed PDF with a full audit trail.
Everything you need to run paperwork end-to-end.
Signum handles the whole life of a document — from first upload to signed, filed, and audited.
Upload any PDF
Import existing forms, contracts, or scanned documents. Signum preserves the original layout and reads native AcroForm fields.
Auto-detect fields
AI-powered detection finds underlines, checkboxes, signature blocks, and dates — even on scanned or image-based PDFs.
Precision field editor
Drag, resize, and fine-tune every field with coordinate-accurate placement. Text aligns to the baseline so filled forms look professional.
Multi-party signing
Assign fields to specific signers, set signing order, and reuse signer profiles. Everyone knows exactly what to fill.
Collect payments on signing
Charge clients at the moment they sign with Stripe Connect. Funds settle directly in your account — no per-signature fees.
Fill from a photo
Snap a paper form and Signum maps the answers into your fillable PDF, saving time on manual data entry.
Templates & folders
Save any document as a reusable template. Organize forms, contracts, and client files in shared workspace folders.
Audit-ready certificates
Every completed signature generates a tamper-evident audit trail PDF with timestamps, signer identity, and document DNA.
Secure by default
Organization-based access controls, private storage, expiring recipient links, and row-level security keep client data safe.
Built for teams that live in paperwork.
Whether you send ten forms a month or ten thousand, Signum keeps the process consistent and compliant.
Legal & contracts
Retainers, engagement letters, NDAs, and fee agreements with client-specific fields.
HR & onboarding
Offer letters, I-9s, handbook acknowledgments, and benefits forms routed to the right people.
Sales & proposals
Quotes, order forms, and SOWs that collect signatures and payments in one flow.
Accounting & tax
Engagement letters, intake forms, and authorization documents sent during tax season.
Client data stays protected.
Security isn't an afterthought. Signum is built with workspace isolation, audit logging, and privacy-by-design controls.
SOC 2-aligned infrastructure on Lovable Cloud
End-to-end encryption in transit and at rest
Granular workspace permissions and audit logs
No training on your document data
