Use cases01

Built for the people who have to prove what happened.

If your job depends on reconstructing who said what, when, and in what order — ThreadLine gets you there in minutes instead of days.

01 / 03
For · HR & Compliance

Workplace investigations & complaints

An employee dispute lands on your desk with six months of emails across three people. ThreadLine surfaces the complaint, the response, and every adverse action on a single page.

Example output: Complaint filed Feb 2 → termination Mar 4. Written acknowledgement, scheduling change, and final notice on one chronology.
02 / 03
For · Legal & Litigation

Chronologies for matters & depositions

Opposing counsel wants the record. Pull every relevant message from a client’s inbox, dated and ordered, with a time-limited share link or a clean PDF you can hand over.

Example output: 40-page chronology with every event traceable back to its source email.
03 / 03
For · Projects & Consulting

Who agreed to what, and when

A client questions what was promised. Every revision, sign-off, and verbal agreement buried across weeks of back-and-forth — extracted, dated, cross-referenced against the final deliverable.

Example output: Decision log showing scope changes, pricing discussions, and who approved each one.

What you get03

Every event, traced back to an email.

i.

Sourced from real emails

Every entry on the timeline links back to the original message — sender, recipients, subject, and date — so the chronology is verifiable, not paraphrased.

ii.

Share a time-limited link

Send a read-only view to outside counsel, HR, or a client. Share links expire automatically and can be revoked any time.

iii.

Export a clean PDF

A numbered, paginated chronology suitable for case files, HR records, or project deliverables. One click.

iv.

Your content isn’t used for training

ThreadLine encrypts email content before it hits our database. We never use your messages to train AI models — not ours, not anyone’s.

Security04

Built for sensitive communications.

ThreadLine handles email content that you can’t afford to leak. So encryption, access control, and data minimisation are defaults, not upsells.
