Use AI on client documents. Keep the names on your Mac.

Download PiBye and use it. Your first 10 documents are free, including redact, review, restore, Lock PDF and the Claude Desktop and ChatGPT desktop app approved-copy connections. In-app Live AI drafting requires a paid PiBye licence. A document counts once, when PiBye first prepares it. There is no PiBye account, no card and no time limit, and free users still receive updates.

When you go to prepare an 11th document, PiBye asks you to buy a licence: $99 CAD one-time, which unlocks unlimited documents and includes twelve months of updates. Nothing you already have is taken away: documents you have already prepared, your saved matters, Restore and Lock PDF are never blocked.

PiBye does not upload your original documents: it prepares and restores them locally and has no cloud relay. Anything you choose to share with an assistant has already been redacted and reviewed by you. This includes a reviewed copy sent through paid, opt-in Live AI drafting. When you enable the optional local connection to Claude Desktop or the ChatGPT desktop app, that assistant can read the approved Markdown Documents you select and submit generated Markdown for review. Your AI provider processes whatever copy you share with it, remotely.

Yes. Each item can be approved, edited or kept. Required items must be resolved before you explicitly approve the final copy. A document with no detected items still needs your approval.

Against real documents and planted identifiers, and the results are published. The first battery ran 50,119 real public documents; independent checks found 84,037 identifiers and 24 were still readable after redaction; all 24 are counted and published, and they are number-shaped values from court filings. A second battery on harder material (completed forms, handwriting, French and Spanish) is still running and is not finished. Neither battery proves your document is clean: review every approved copy before sharing it.

Two ways. Copy the approved text into any AI chat, or connect Claude Desktop or the ChatGPT desktop app locally so they can read the approved copies you select. The connection runs on your Mac with no PiBye cloud relay, and the key to the real names never leaves your Mac. Your AI provider still processes what you share, which is the case with names and identifiers already replaced.

In-app Live AI drafting is available with a paid PiBye licence and stays off until you turn it on in Settings. It uses your signed-in Claude Code or Codex account; Claude Desktop and the ChatGPT desktop app are separate approved-copy connections, not Live AI providers. The provider receives the reviewed copy you choose to send, while your original document and name mapping stay on your Mac. Renewing updates is optional and does not end your paid licence.

Open the same Document, choose the approved copy you shared, and drop the returned file into Restore. Review found and missing stand-ins, resolve any differences, then approve the final restoration. PiBye saves a separate restored file in the private Vault and preserves supported new text.

Yes. Lock PDF is built for sending completed forms to clients for review. It saves a static copy of each filled-in PDF form with every answer printed into the page and the fillable fields removed, so the client can check the answers but cannot retype, clear or reset them. The copy is saved beside the original as “(static).pdf”, and the original is not changed.

No. PiBye's local processing and review controls are product behavior, not a certification or a guarantee that a particular use meets your professional obligations.

Nothing breaks. PiBye keeps working, with unlimited documents, exactly as before. You simply stop receiving new versions until you choose to renew for $39 CAD, which adds another twelve months of updates.
