AI that assists. A person who decides.
1sitting uses AI to prepare more thoroughly than any single person could in the time available. A named human neutral hears your case, decides every issue and signs every decision.
Who does what

AI helps the neutral
- Organises both Position Papers side by side
- Maps every issue, fact and claimed amount
- Finds where the parties already agree
- Checks the arithmetic
- Suggests questions for the hearing
- Drafts material for the neutral to review

The neutral decides
- Hears both sides in person
- Weighs the evidence and the arguments
- Decides every issue
- Writes, amends and signs the decision
- Leads the mediation
- Answers to both parties for the result
How we test for bias
1
Same questions for everyone.
Every party completes an identical Position Paper, so one side cannot gain an advantage by writing more.
2
Names removed.
Company and personal names are replaced with "Party A" and "Party B" before any AI analysis.
3
The swap test.
The analysis is run again with the parties' positions swapped. If the result changes, the neutral must find out why before anything is sealed.
4
Everything traced to the record.
Every finding must point to something a party actually submitted. Anything that cannot be traced is struck out.
How your information is protected
- Your case information is processed only through business AI services whose terms do not allow your data to be used to train AI models.
- Your Confidential Annex is never shown to the other party, and is used only after the decision is sealed.
- Your client area is private to you. Other members cannot see your case.
- Records are kept only as long as your agreement says, and the sealed decision is destroyed if you settle.
- How AI is used in your case is disclosed in writing in your Participation Agreement.
Built for the strictest rules
New rules on AI in arbitration require that the arbitrator, not the AI, makes the decision, and that AI use is disclosed. 1sitting was designed that way from the start: a human neutral decides every issue, the AI works only from the record, and its use is disclosed to both parties.
