Run chess tournaments, not paperwork.
Arbiter automates the slow, repetitive parts of running a chess tournament — online entries, batch FIDE & AICF membership checks, pairing sheets, prize lists and arbiter norm forms — so you can focus on the event.

Take registrations without the WhatsApp scroll
Open a public registration page for your tournament, collect entry fees over UPI or bank transfer, and verify each payment yourself — all in the same place you run the event.
- One link, no accounts
- Share a public registration link. Candidates fill in their details — FIDE ID, AICF ID, rating, date of birth — plus any custom questions you add.
- Collect the entry fee
- Publish your UPI ID, a payment QR and instructions. Candidates upload a payment screenshot with their entry.
- Verify on your terms
- Review the proof, then confirm, waitlist or reject each entry. Caps and closing dates shut the form automatically.
- Straight into your workflow
- Export every registration to Excel, or start a membership analysis directly from the entry list — already-checked IDs are skipped.

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 — or pull them straight from your registration list — and Arbiter does it all in one pass, processing 350 players in roughly 20–30 seconds.
- Paste or pull from entries
- Drop in a mixed batch of FIDE and AICF IDs, or import them from your registrations — players already checked are skipped.
- 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. Review the eligible-versus-allocated breakdown for every prize before you publish, and override any allocation by name.
- 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 an Excel prize list — one sheet per category or everything stacked on a single printable sheet.

Generating for 4 arbiters
Arbiter norm forms, filled in for you
Retyping the same event block onto every arbiter's norm form is exactly the kind of work Arbiter exists to remove. Configure it once, then download one document per arbiter — or every form in a single file, a page each.
- FA1 and IA1, ready to sign
- Generate the FIDE Arbiter (FA1) and International Arbiter (IA1) norm report forms as Word documents, formatted the way FIDE expects them.
- Type the event block once
- Fill in the event details and signatory once per norm type, then add each arbiter — recipients prefill from your tournament members' profiles.
- Never a half-filled form
- If a required field is still empty, Arbiter names the gaps instead of producing a document you'd have to fix by hand.
