Most e-signature tools need a finished PDF before you can do anything. Signvoy lets you write the document in the browser instead — with signature and input fields living inside the sentences — or upload a PDF when you already have one.
A field inside a sentence
This Agreement is entered into by Full name and takes effect on Date.
The highlighted parts are real fields. Whatever a signer types becomes part of the sentence, and the paragraph reflows around it instead of clipping at a box edge.
Two ways to start. One place to finish.
The choice is per document, not per subscription. Pick whichever fits what you already have.
Write the document
Draft the text in a rich-text editor and drop fields directly into it. Useful when the document does not exist yet, or when the wording changes for every deal.
- Start from a blank page, a gallery template, or an AI draft
- Fields sit inline, so the text flows around signer input
- Edit the wording without re-placing a single field
Upload a PDF
Drop in a PDF that legal already approved and place fields on the page with pixel precision. Useful when the layout is fixed and must stay that way.
- Combine several PDFs into one document on upload
- Drag fields anywhere on any page
- Have AI detect the fields for you
Both paths land in the same editor, produce the same signing experience, and finish as a certified PDF with a verifiable hash. Nothing is gated behind a higher plan just because of how the document started.
The same engine behind both
This is the part that usually costs you a second subscription. Written documents are not a lesser mode — every capability below works identically whether you typed the document or uploaded it.
The same field types
Signatures, initials, text, dates, checkboxes, dropdowns, and radio groups, assigned to whichever recipient should fill them.
Conditional logic
Show, hide, or compute fields from earlier answers. The rules engine does not care where the field is anchored.
Multi-recipient routing
Sequential or parallel signing orders, per-recipient roles, and CC recipients on every document.
Tamper-evident audit trail
An append-only event log plus a SHA-256 hash of the final PDF, so a written document is as provable as an uploaded one.
Automatic reminders
Chase whoever is holding the document up on a schedule you set, with expiry dates when a deadline matters.
REST API and webhooks
Create, send, and collect documents programmatically, with HMAC-signed webhooks on every state change.
Why it matters
A fixed box cannot grow. A sentence can.
When a field is a rectangle drawn on a page, its size is decided before anyone has typed anything. That guess is fine for a date and wrong for a name. The industry's answer has been to shrink the font, overflow into the margin, or truncate — every option is a compromise, and the signer usually finds out after signing.
An inline field has no box to run out of. It is part of the paragraph, so a long value pushes the rest of the sentence along and the page re-lays itself out. The certified PDF is rendered from the same text after the values are known, which is the only point at which the correct layout is actually knowable.
Fixed box on a page

The value is wider than the box, so something has to give.
Field inside the text
This Agreement is entered into by Alexandra Fitzgerald-Whitmore as of the date below.
The sentence grows and the page reflows. Nothing is lost.
From blank page to signed PDF
Four steps, no file conversion anywhere in the middle.
Start writing
Open a blank page, clone a gallery template, or describe what you need and let AI draft it.
Drop in fields
Place signature, text, and date fields inline as you write, and assign each one to a recipient.
Send it
Add signers, set the order and reminders, and publish. Signers get a link — no account needed.
Get the certified PDF
Once everyone has signed, the PDF is rendered from your text plus the real values, hashed, and archived.
How this compares
Doing both is rare, but it is not unique. What is unusual is getting there without a sales call, a seat minimum, or an annual commitment.

Checked against each vendor's own public pricing page on 8 August 2026: US list prices on annual billing where offered, before tax. Availability varies by region and plan. “Upload only” means a file is required to produce a signable document — several of these tools accept DOCX but convert it to PDF and discard the original, and a PDF editor for annotating an uploaded file is a different thing from authoring one. Vendors whose pricing or authoring model we could not confirm from a public page that day, including Dropbox Sign and Juro, are left out rather than estimated.
PandaDoc and Oneflow both genuinely support the two document models, so this is not ours alone. Where we differ is the way in: PandaDoc's free tier stops at five documents a month and puts its API on Enterprise, and Oneflow is annual-only from five users with no published price. And if your contracts get negotiated clause by clause, Oneflow and Juro are built for that and we are not. We wrote the whole comparison up, losses included. Read the full comparison
What the editor does not do yet
Written documents support headings, lists, quotes, bold, italic, underline, and strikethrough. Tables, images, links, and explicit page breaks are not supported yet, and there is no clause-by-clause redlining or counterparty negotiation. If your document depends on any of those, upload it as a PDF — that path has no such limits.
Yes. When the last signer finishes, Signvoy renders the document to a PDF from your text plus the submitted values, hashes it with SHA-256, and stores it alongside the audit trail. You download an ordinary PDF that anyone can open, and the hash lets you prove it has not been altered since. The difference is only in how the document was authored, not in what you end up with.
