One participant = one tab = one conversation

The extension automates the provider's own web UI you are already logged into. No API keys, no backend, no copy-paste. Pause, skip, retry, intervene at any time. History stays in chrome.storage.local.

AdversarialDecision boardDevil's advocateFact-check
◈ Local-first & privateNo telemetry. No server sees your prompts.

Three steps. Watch it live.

You write the topic once. Arguora orchestrates the rest — structured prompts, opponent context, referee scoring — while you keep control.

01 — SETUP

Pick 2 debaters + optional panelists

Any pairing — ChatGPT vs Claude, Gemini vs Grok, even ChatGPT vs ChatGPT in two separate conversations. Add up to 2 panelist AIs that audit instead of argue. Choose objective, roles, rounds, stop rules.

02 — LIVE

They argue. Referee scores.

Each turn passes topic + roles + opponent's argument + shared debate memory + concrete tasks. Referee tracks consensus & new-information, decides when to stop. Intervene, pause, skip or retry at any time.

03 — VERDICT

One synthesis to act on

Conclusion, agreements, disagreements, strongest arguments, concessions, uncertainties, next step — plus decision board, Borda ranking, claim map and falsifier pass when enabled. Export Markdown / HTML / PDF / PNG.

Built for real decisions, not chat theater

Dense, keyboard-friendly, honest about uncertainty. The numbers keep their spread — agreement is not truth.

◈

6 objectives

Adversarial, Collaborative, Devil's Advocate, Decision Making, Fact & Reasoning Review, Custom — each injects its own rules and brief into every turn.

◐

Decision board

Name 2–6 options. Each AI ends turns with probabilities. Board averages latest per AI, shows every AI's mark, margin band, agreement meter, and a coin-flip tiebreak when it's a toss-up.

◎

Referee + panelists

Referee warms during round 1, scores consensus/new-info, writes the synthesis. Panelists audit both sides each round — referee weighs their findings.

⬙

In-page command deck

Shadow-DOM launcher pill, per-answer Debate / Cross-check / Quote, selection bubble, composer button, side panel — on the 5 provider sites, not just the dashboard.

▦

History that survives

Searchable (fuzzy), tags, local reliability stats, reopen participant tabs, extend by 2 rounds, regenerate synthesis, import/export JSON.

⚑

Advanced rounds

Blind peer ranking + Borda, falsifier/red-team pass, auto-dropout, claim map with local number/date/URL flags, 6 file attachments verified per provider.

Privacy by architecture

No backend. storage · tabs · alarms · sidePanel only. Transcripts in chrome.storage.local. In-page UI only on the 5 hosts — never <all_urls>.

Reliability (MV3)

Every transition persisted before the network wait, 20s keep-alive, 30s watchdog + on-startup recovery, hard-navigation recovery, actionable bars — never silent hangs.
