One input. Three minds. Infinite perspectives.
A Chrome Extension that lets you control ChatGPT, Claude, and Gemini simultaneously through a single Side Panel UI — send one message and watch three AI giants respond in real time, or orchestrate them in structured multi-step workflows.
- Unified input — type once, broadcast to all three AIs
- 5 chat modes — from free-form parallel chat to sophisticated multi-round debates
- Real-time streaming — responses appear as they're generated
- Workflow status bar — tracks current step in serial modes with live progress
- Role labels — each AI response tagged with its role (正方 / Reviewer / Coder, etc.)
- Role assignment — customize which AI plays which role per mode
- Cancel anytime — abort in-progress workflows with one click
- Markdown export — download the full conversation as a
.mdfile - Connection management — detects login status per AI, one-click quick login buttons
Send to all 3 AIs in parallel. Independent answers, no coordination.
User → ChatGPT
→ Claude
→ Gemini
Structured pro/con/summary dialectic.
User → Pro (step 1) → Con rebuts Pro (step 2) → Summarizer concludes (step 3)
Multi-perspective research with cross-review.
User → First Answer → Reviewer checks + adds → Summarizer synthesizes (step 3)
A full software engineering double-loop: spec → review → implement → review → fix → acceptance → final.
Planner writes spec (1)
→ Reviewer challenges spec (2)
→ Coder writes v1 (3)
→ Reviewer does code review (4)
→ Coder fixes → v2 (5)
→ Planner does acceptance test (6)
→ Coder delivers final (7)
A 5-round dialectical spiral. Truth through adversarial discussion.
Round 1: Opening statements (3 AIs × position)
Round 2: Cross-examination (attack weaknesses, acknowledge strengths)
Round 3: Defense + refinement (respond to challenges, update positions)
Round 4: Core convergence (map consensus vs. genuine disagreement)
Round 5: Truth emerges (final conclusions, honest position changes)
Each round: 3 AIs × 5 rounds = 15 total steps.

This is a personal side project built for exploration and fun. It works by injecting content scripts into ChatGPT, Claude, and Gemini's web interfaces — which may violate each platform's Terms of Service.
