AI Document Signing Automation for macOS
The average employee signs or initials 50+ documents per month, according to a 2024 Adobe survey. That includes contracts, NDAs, vendor agreements, internal approvals, and compliance forms. Every existing signing solution (DocuSign, HelloSign, PandaDoc, Adobe Sign, SignNow) is a cloud SaaS product that requires an account, a subscription, and often API integrations with your other tools. None of them can control the signing app sitting on your Mac screen. Fazm is a desktop AI agent that operates Preview, any browser-based e-signature platform, or desktop PDF editors through macOS accessibility APIs. You tell it what to sign, and it handles the clicking, placing, and saving for you.
Document Signing Is Repetitive and Cloud Tools Lock You Into Their Platform
The typical signing workflow looks like this: receive a contract via email, download the PDF, open it in a signing platform, create an account or log in, upload the document, place your signature, add your initials on each page, fill in the date, download the signed copy, and email it back. For a single document, that is 10+ steps across three different apps. When you have a stack of NDAs or vendor agreements to process, the friction multiplies. Each platform has its own interface, its own account, and its own way of handling signature placement.
Every major e-signature tool (DocuSign, HelloSign, PandaDoc, Adobe Sign, SignNow) is a cloud SaaS product. They solve the problem of getting signatures from other people, but they add overhead when you just need to sign documents yourself. Your Mac already has PDF signing built into Preview. Fazm works differently: it controls the signing app on your Mac screen through accessibility APIs. It can use Preview for simple PDF signing, navigate DocuSign in your browser for documents that require e-signature workflows, or operate any desktop PDF editor. No extra accounts, no API integrations, no uploading documents to yet another cloud service.
| Manual Signing | Cloud SaaS (DocuSign, HelloSign) | Fazm Desktop Agent | |
|---|---|---|---|
| Setup time | None, but slow every time | Account creation, plan selection, onboarding | Seconds (just open your PDF or browser) |
| Works with Preview (built-in Mac signing) | Yes, but tedious for batches | No (separate platform) | Yes (controls Preview directly) |
| Works with browser e-sign platforms | Yes | Only their own platform | Yes, any platform in any browser |
| Batch signing | One at a time, manually | Bulk send only (requires recipients) | Signs a queue of documents sequentially |
| Cross-app workflows | Copy-paste between windows | Limited to supported integrations | Sign in one app, email from another |
| Data privacy | Local | Documents uploaded to cloud servers | Local, documents never leave your Mac |
Commands You Can Give Fazm
How Fazm Automates Document Signing
Open your document and signing app
Open the contract, NDA, or agreement in Preview, your browser (for DocuSign or HelloSign), or any desktop PDF editor. Fazm works with whatever is visible on your screen.
Tell Fazm what to sign
Describe the signing task in plain language. Fazm understands instructions like 'sign page 3,' 'initial every page,' or 'sign all five pending documents in DocuSign.'
Fazm navigates the signing interface
Fazm clicks through the app interface: opening the Markup toolbar in Preview, selecting your saved signature, placing it on the correct line, filling in dates and initials, and confirming the submission. It handles multi-page documents, scroll navigation, and confirmation dialogs automatically.
Review and send
Fazm saves the signed document and reports what it completed. It can also handle the next step in the workflow, like attaching the signed PDF to an email or moving it to a specific folder.
Why a Desktop Agent Beats DocuSign and HelloSign
Works with any signing app on your Mac
DocuSign and HelloSign only work within their own platforms. Fazm controls Preview, any browser-based e-sign service, and desktop PDF editors. One agent for every signing workflow, no matter which app you use.
Your documents stay on your Mac
Cloud e-signature platforms upload your contracts to their servers. Fazm reads your screen locally and never sends document content off your machine. Sensitive contracts stay where they belong.
Cross-app signing workflows without integrations
Need to read a contract in one app, sign it in Preview, and email the signed copy from Mail? Fazm handles the full workflow across apps. No Zapier, no API connectors, no middleware.
A Real-World Example
A startup founder receives 8 vendor agreements and 3 NDAs at the start of each quarter. Each document needs her signature on the last page, her initials on every other page, and the current date filled in. She normally spends 45 minutes opening each PDF, switching to Preview, using the Markup toolbar, placing her signature, scrolling through pages to add initials, saving, and emailing the signed copy back. She opened her contracts folder in Finder and Preview, then told Fazm:
"Go through each PDF in my Q2 Contracts folder. For each one, open it in Preview, add my signature on the last page, initial every other page, fill in today's date next to the signature, save the signed version to my Signed folder, then attach it to a reply in Mail to the sender."
Fazm processed all 11 documents in 18 minutes. It signed each contract, added initials on the required pages, filled in the date, saved the signed copies, and drafted reply emails with the signed PDFs attached. The founder reviewed each email, confirmed the signatures looked correct, and hit send. Her quarterly signing stack was done before her first meeting of the day.
Frequently Asked Questions
How is Fazm different from DocuSign or HelloSign?+
DocuSign, HelloSign, PandaDoc, and similar tools are cloud SaaS platforms that require accounts, subscriptions, and API integrations. Fazm is a macOS desktop AI agent that controls any signing app already on your screen using accessibility APIs. It works with Preview, browser-based e-sign platforms, and desktop PDF editors without needing API keys or cloud accounts.
Can Fazm sign PDFs in macOS Preview?+
Yes. Preview has built-in PDF signing support on macOS, and Fazm can control it directly. It opens the Markup toolbar, selects your saved signature, places it on the correct page, resizes it, and saves the document. No third-party signing platform required.
Can Fazm handle batch signing of multiple documents?+
Yes. You can point Fazm at a folder of contracts or a queue of documents in DocuSign, and it will work through each one sequentially. It opens each document, locates the signature fields, applies your signature, and moves to the next. You can also tell it to initial specific pages or add dates where required.
Is my document data safe with Fazm?+
Fazm processes screen content locally on your Mac. Your contracts and documents are not uploaded to external servers. The AI reads what is visible on your screen and performs actions in your signing app, just like a person sitting at your desk would.
