チームでのpdftek活用例

From inbox to executed, without leaving the page.

  • A vendor MSA lands. An automation extracts risk flags against your playbook and pings #legal.
  • Counsel asks “what's our exit path?” and gets the termination-for-convenience clause, with a link to page 2.
  • They check the document out, redline the notice period in place, and save v3. Nobody else can overwrite it.
  • They hand it to Contracts, who sends it for signature in order. Reminders go out automatically.
  • Once it's fully signed, key terms go to the tracker, and a renewal reminder is set for 60 days before expiry.

監査証跡
Activity logs, signer IP addresses and timestamps, and certificates of completion.

セキュリティ

漏えいが許されない文書のために設計。

Contracts, financials and patient records need more than a free converter site. pdftek keeps your files in your workspace, logs who touched what, and can run entirely on your own servers.

your documents and cites the page for every claim. Click a citation and the passage is highlighted in the viewer, so you can check any answer in seconds.のpdftek answers only

Can it read scanned documents and other languages?

Yes. The assistant reads scans directly, and in-browser OCR adds a searchable text layer in 13 languages. Search, read-aloud and conversions work across 40+ languages.

電子署名に法的拘束力はありますか?

pdftek captures consent, signer identity via unique email links, IP addresses and timestamps, and adds a certificate of completion to theがPDF. That's the standard evidence under ESIGN and eIDAS for simple electronic signatures. Check your jurisdiction's requirements for regulated documents.に署名しました

2人が同時に編集するとどうなりますか?

They can't overwrite each other. Editing checks the document out to one person, and teammates see who holds the lock. You can hand it off or check it back in at any time, and admins can release a stale lock.

自社でホストできますか?

Yes. pdftek ships as a single Docker image with a built-in database and file storage. Bring your own Anthropic API key for the AI features and your own SMTP server for email.
