Private PDF Agent · beta

Tell your PDF what to do.

Describe the change in plain English. The agent proposes a clear plan, you review every step, and only then is it applied — locally. The file never leaves your browser; only the extracted text is ever sent to AI, never the document. And unlike a promise in a privacy policy, you can prove it.

The thing no upload-based AI tool can say

Every mainstream “AI PDF” tool uploads your document to its cloud to process it, and most of them chat or summarize about the file rather than editing it. The few genuinely on-device tools are manual button grids with no agent at all. AttachKit is the one place where all three are true at once:

• Zero-upload. The PDF is parsed and edited inside your browser tab. The file is never sent to a server.
• Agentic. You describe the outcome; the agent figures out the operations.
• Reviewable before apply. You approve a plan first — nothing changes until you do.

How it works

1. Add your PDF. It loads in your browser — no upload.
2. Tell the agent what to do (“delete the blank pages”, “rotate everything upright”, “keep only pages 1–3”). Only the extracted page text is sent so it can locate things — never the file.
3. Review the action plan — an ordered, labeled list of every change, with destructive steps flagged. Accept, edit, or reject each one.
4. Apply locally and export a copy. Your original is never modified.

Don't take our word for it — check the network tab

You can verify the zero-upload claim yourself, in under a minute:

• Open the agent and add a PDF.
• Open your browser's developer tools and switch to the Network tab.
• Ask the agent to do something. You'll see a request carrying the page text— and never the file bytes. The full account of what does and doesn't leave your device is on the security page.

Built for people who can't upload the document

The agent is the same tool, framed for the work that makes uploading a non-starter — a privileged memo, a client's return, a sensitive immigration form:

• For lawyers — edit privileged PDFs with nothing transmitted to a server you don't control.
• For accountants — work on client financials without a server-side copy to retain or breach.
• For immigration filers — prepare sensitive government forms that never leave your device.

Honest scope

The agent proposes; you apply — it never edits on its own. Today it handles page and text operations (rotate, delete, extract, add text, stamp) with more on the way; if you ask for something it can't do yet, it says so instead of approximating. The AI planning step is the only part that leaves your device, and it sends only extracted text — never the file. The agent is in private beta; the rest of AttachKit is live today.
