Features
Everything CoreSign does today.
Each line is live now. Where a feature belongs to some plans, it says which; everything else comes with every plan, Free included, within each plan’s monthly documents. Plans and prices
Sending documents
- Upload or reuse
- Upload a PDF, or start from a template you saved.
- Find fields for me
- The places to sign and fill are suggested from the PDF’s own text and lines, by rules, not by AI: signatures, initials, names, dates and text lines. You keep, move or drop each one. A scanned page has no text to read, so you place those fields yourself.
- Field kinds
- Signature, initials, name, date, email and one line of text; checkboxes, radio buttons and drop-down lists of 2 to 20 choices; numbers within a range; dates; and text in a set format (email, US phone, US ZIP) or of a set length. The signing page checks each answer.
- Signers and copies
- Up to 25 people per document, signers and copies together. Signers sign in the order you set: one after another, or several at the same step, asked at once and signing in any order. The next step starts when all of them have.
- Copies
- Name people to be sent the signed document and its certificate when everyone has signed. They sign nothing. A copy can also get a link to read the document while it is being signed.
- Codes for signers
- Ask a signer for an access code you give them yourself, a six-digit code we email to them, or both.
- Reminders and expiry
- Reminders are on by default, and you can turn them off for a document. A request lapses when the time you set runs out, and you are told when one does.
- Withdrawing
- Withdraw a document that is out for signature, with a reason everyone it was sent to is told.
- Client profiles
- Keep the people you send to, with notes.
- Notifications
- Choose whether you are emailed when a document is signed, declined, completed or lapses.
- Saved signatures
- Keep your signature and initials, and use them when you sign a document sent to your own address while you are signed in.Essentials, Pro and Business
- Your branding on the signing page
- Your name at the top of the page your signers see.Pro and Business
For the people you send to
- Free to sign
- Signers never need an account and never pay.
- Every page first
- Every page is shown before signing opens, and the signer is taken to their own places.
- Consent as its own step
- Agreeing to sign electronically is its own box, under the disclosure it accepts, separate from the intent to sign. A signer who does not agree can decline instead.
- Draw or type
- A signature can be drawn or typed.
- Declining
- A signer can decline, with an optional reason the sender is emailed.
- Names in many scripts
- Names in Greek, Cyrillic, Hebrew, Arabic, Chinese, Japanese, Korean or Vietnamese script print correctly on the signed document.
- On a phone
- The signing page works on a phone as well as a computer.
The evidence
- Certificate of completion
- Each step of the signing and when it happened, issued with the signed document.
- The seal
- Each completed document is sealed: a signature over the fingerprints of the document and the certificate, and over each signer’s entry. A document that cannot be sealed is not completed.
- Check a signed PDF
- Drop a copy on our checking page: your browser works out its fingerprint and sends only that.
- A checker you run yourself
- The checker we publish runs on your own computer, against a sealed record you downloaded.
Your account
- Sign in
- With an email address and password, or with Google.
- Two-step sign-in
- An authenticator app with recovery codes, and a passkey as a second step.
- Activity
- Every account has an Activity page that lists its sign-ins and security events, what happened to its documents, and its payments.
- Activity export (CSV)
- Save those lists as CSV files.Business
- Display settings
- Text size, reduced motion, high contrast and underlined links, kept with your account.
- Deleting your account
- Ask, confirm from the emailed link, and the account is deleted fourteen days later; you can cancel until then. Confirming locks the account at once, withdraws documents still out for signature and revokes API keys, and cancelling does not undo those. Cancel a renewing plan first.
- Buying a plan
- Choose a plan, then sign up with Google, or confirm your email address in the same browser within an hour, and you go straight on to checkout. Paid plans need a US billing address for now.
Developers and AI agents
- Test mode
- Test keys on every plan. A test document goes only to your own confirmed addresses, is marked as a test and does not count.
- API access
- A REST API with an OpenAPI document and a reference. Your software prepares documents, follows their progress and downloads the finished records. No key can send.Essentials, Pro and Business
- An MCP server
- AI assistants connect through OAuth once you approve them. Six tools, and none of them sends: a draft waits until a signed-in person sends it or rejects it.Essentials, Pro and Business
- Clients and their limits
- Every live key belongs to a client you register: Essentials 1 at a time, Pro 2, Business 10, and a connected AI assistant counts as one. You can limit each to certain templates, recipient email domains, a number of drafts a day and an end date, and suspend or revoke it.Essentials, Pro and Business
- Safe retries
- Send an Idempotency-Key when creating a document from a template, and a retry within 24 hours makes no second draft.Live keys: Essentials, Pro and Business; test keys: every plan
- Webhooks
- A web address you choose is told when a document is sent, signed, completed, declined or withdrawn, usually within about a minute.Business
