The signing system of record
Document signing for the agentic era.
Upload a file, prepare the fields, and send it for signature. Use your favorite Agent or CLI.
One free send a month · Signers never pay · Nothing to install
The seal
One signature covers every byte you approved. Change anything later and the signature breaks. Anyone can check that in a normal PDF reader, offline, with no account.
The ledger
Each event is linked to the one before it. Remove or change a step and the chain shows it.
The check
Anyone can check a sealed file with no account.
Your documents
Every model request requires zero-data-retention routing and prompt-training opt-out.
Move from file to signed PDF.
Upload or choose a form.
Bring a PDF, DOC, or DOCX file, or choose a source-checked reusable PDF form.
Prepare, send, and sign.
Find or add fields, assign signers, review the exact PDF, and send it. The other side signs in the browser.
Keep the signed PDF.
Everyone gets the same signed PDF back, ready to download from their account.
The same pages you sent. The same signed PDF back.
The document that answers
Ask the document a question. Get the exact passage back.
Ask Octo answers supported factual questions from the document you uploaded, while you prepare it and while the other side reads it.
Ask the file
Ask a factual question and get the exact passage that answers it, with its page. Open its page and read the surrounding terms yourself.
The refusal is the feature
An answer with no matched passage and page is not shown as a citation. A general chatbot in another window can produce a fluent answer about any PDF. It cannot bind its answer to this stored passage and page, or refuse because no passage matched.
Ask Octo identifies itself as software on every signer surface. Ask Octo reports what the document says and where. It is software, not a lawyer, and it is not a substitute for the advice of an attorney.
For the person signing
Built for the person signing, too.
The person asked to sign gets a link, the full file, and a place to ask a factual question. Signing costs them nothing.
Signing costs nothing
Signer accounts are free. No plan, no card, no trial that converts into a charge. Nothing to install.
Read it all first
The signer can read every page, download or print the file, and move only between the marks assigned to them. A separate review step catches a missing mark before the final action.
Questions have a destination
Ask a supported factual question before you sign and get the exact passage and page that answer it. Ask the sender directly when the document cannot answer; OctoDoc will not send the question automatically.
Keep the signed PDF
After the last signature, the sender and every signer get the same signed PDF, ready to download from their account. What you signed does not live behind someone else's subscription.
Agents and the CLI
Your agent can prepare the document. A person confirms the signature.
List what is waiting and read the exact file from your CLI or the agent you already use. The path prepares; a human browser gesture finishes it. OctoDoc publishes no installer.

Paste this into your agent
Open https://octodoc.org/agents and set up OctoDoc for this computer. OctoDoc publishes no installer, so follow the checkout instructions on that page exactly and do not invent one. Do not report an install as done, and do not report success until OctoDoc confirms the account. Then use OctoDoc to Prepare, Send, and Sign documents from this agent.What the credential will not do
A saved login is identity, not authority. Without an explicit mandate, the agent can open an imported file or a reviewed reusable PDF form, read cited facts, and prepare measured fields. It cannot choose a legal instrument for you. A transaction-bound authenticator ceremony authorizes each send or signature. A valid mandate can authorize the agent to complete only the exact acts it covers. OctoDoc records agent origin in either mode.

Compared
Where OctoDoc differs from the typical e-signature suite.
The left column describes the category's common practice, and every line in the right column is a registered, supportable claim or a published decision.
The person signing
A place to collect a mark. Questions leave the product and go to email.
A free account, a cited answer on the page, and the sealed PDF to return to.
AI answers
A fluent paraphrase with no obligation to show where it came from.
An answer quotes the page it came from, or it is not shown as a citation.
Checking the record
A signing record that lives in the vendor's account and is shown on request.
One signature covers every byte you approved. Anyone can check it in a normal PDF reader, offline.
Documents and model training
Training permissions have arrived by terms update, mid-relationship.
Every model request requires zero-data-retention routing and prompt-training opt-out.
The middle column describes common practice across the category, not any single product. Verify any vendor fact against that vendor's current published plans before relying on it.
Open to every team
Nothing here is capped by company size. Larger firms use the same sending, the same seal and the same free signer accounts, and add senders as the team grows. What a bigger organization should check first is the list of things we do not have yet — that inventory is published on the security posture rather than left for a sales call.
Trust
Built so you can verify it yourself.
Four controls you can check. Full detail for a security review lives in Security posture and the Trust Center.
The signature protects the whole file.
One signature covers every byte you approved. Change anything later and the signature breaks. Anyone can check that in a normal PDF reader, offline, with no account.
Any PDF reader can check it offline — no account required
Every step is recorded and linked.
Each event is linked to the one before it. Remove or change a step and the chain shows it.
Each entry digests the previous one
