Run chess tournaments, not paperwork.
Arbiter automates the slow, repetitive parts of running a chess tournament — batch FIDE & AICF membership checks, pairing sheets, live broadcasts and formatted reports — so you can focus on the event.
- Free to start
- No card required
- 7-day Pro trial
One toolkit for the whole tournament
From the first invite to the final prize list — Arbiter handles the busywork that used to eat your event.

Audit logs
Every tournament change recorded in an insert-only, tamper-evident log.
Verify hundreds of memberships in seconds
Checking each player's FIDE and AICF status by hand takes hours and invites mistakes. Paste up to 500 IDs and Arbiter does it all in one pass — processing 350 players in roughly 20–30 seconds.
- Auto-detects ID type
- Paste a mixed batch — FIDE (5–9 digit) and AICF (state + year) IDs are recognised automatically.
- FIDE + AICF cross-check
- Pulls name, rating, title, federation, age and active status, then cross-references AICF membership.
- Chunked parallel workers
- Edge functions fan out the batch into chunks processed in parallel — no waiting on a single slow request.
- Live progress
- Watch the progress bar fill in real time, then download the Excel report the moment it's done.

A player's phone rings during the game. What's the ruling?
If a player's phone produces a sound in the playing venue, that player loses the game. The arbiter determines the opponent's result based on the position.
The arbiters' manual, on demand
Stop flipping through PDFs mid-round. The Rulebook assistant is a retrieval-augmented chatbot trained on the FIDE Arbiters' Manual — ask in plain language and get a precise, cited answer.
- Grounded in the FIDE manual
- Answers are drawn only from the FIDE Arbiters' Manual — not the open internet — so guidance stays authoritative.
- Cited, every time
- Each response points back to the relevant section and page, so you can verify the ruling in seconds.
- Honest about scope
- If your question falls outside the manual, it says so rather than guessing.
Prize giving without the late-night maths
Define your prize structure once, then let Arbiter match winners to prizes from the final standings — handling overlapping categories and tie-breaks so no one gets paid twice and no prize is missed.
- Categories your way
- Build prize categories — age groups, rating bands, or custom filters like Best Female — each with as many places as you need.
- Trophies & cash, any currency
- Mark each prize as a trophy, a cash amount, or both. Works in INR, USD, EUR, GBP and AED.
- Standings in, prize list out
- Upload final standings and Arbiter allocates every prize automatically, then exports a clean Excel prize list.
