ChatHub and Suprmind both let you query multiple frontier AI models from a single interface. Both put GPT, Claude, and Gemini in the same view so you can compare answers without switching tabs or paying for three separate subscriptions. Both let you bring your own API keys, search the live web inside chat, upload files for analysis, and keep a searchable history of past conversations.
If ChatHub is what you’re using now, everything you depend on, Suprmind handles too: multi-AI in one place, GPT and Claude and Gemini together, BYOK to OpenAI and Anthropic and Google, file upload, web search, prompt library equivalents, chat history with full-text search.
What you also get on Suprmind:
Six structured orchestration modes — Sequential, Super Mind, Debate, Red Team, First Principles, and Research Symphony — that go beyond split-pane comparison. A synthesis layer in Super Mind that produces a unified answer with consensus and divergence flagged, not just five raw outputs in panes. A Master Document Generator that exports any conversation as one of 25+ professional formats: Investment Memo, Executive Brief, SWOT, Legal Brief, Research Paper. A Decision Validation Engine that turns analysis into a GO / NO-GO verdict with FMEA-style risk register. Project Knowledge Graph that auto-extracts entities and decisions across conversations. Perplexity Sonar Reasoning Pro included on Pro+ (ChatHub does not include Perplexity). Hosting in EU and Switzerland.
ChatHub does the browser-native form factor well. The extension lives in your existing tab with a keyboard shortcut, the web app and desktop apps cover macOS and Windows, and the iOS and Android apps round it out — that’s a wider surface area than Suprmind’s PWA. The free tier with optional cookie passthrough to your existing ChatGPT Plus or Claude Pro account is genuinely clever. Founded in 2023 by indie developer Yang Wang and grown to 300,000+ users, ChatHub is a mature product. For chat-driven multi-AI comparison without leaving your browser tab, it earns its place. For decision work that needs structured deliberation, defensible reasoning, and exported deliverables, Suprmind’s mode richness, decision tooling, and Master Doc Generator are the better fit.
THE COMPETITOR
What is ChatHub?
ChatHub is a multi-model AI chatbot client launched in 2023 by indie developer Yang Wang (the Jike HK Limited entity behind it ships from Hong Kong). The pitch — direct from their homepage — is “Unlock the Power of Multiple AIs: Get insights from ChatGPT, Claude, Gemini, and more — all at once!” The product started as a Chrome extension and has since expanded to a web app, native iOS and Android apps, and Windows / macOS desktop apps. Its distinguishing feature is the side-by-side split-pane layout: pick any 2, 3, or 4 chatbots and run a single prompt across all of them, with raw outputs displayed in parallel panes.
FORM-FACTOR-FIRST POSITIONING (May 2026)
ChatHub’s marketing leans on “300,000+ happy users” social proof and the breadth of its access surface — Chrome Web Store version 4.1.0 has 200,000 users at a 4.7 rating across 1,300+ reviews, plus native apps on App Store and Google Play, plus desktop installs for Windows and both Apple Silicon and Intel macOS. The current model lineup in the live app includes GPT-5.5, GPT-5.5 Thinking, Claude Sonnet 4.6, Gemini 3.1 Pro, Gemini 3 Flash, Grok 4.3, DeepSeek-V4 Pro, Qwen3.6 Plus, GLM-5.1, and MiniMax M2.7, with 20+ models total per their marketing. Pricing is gated behind sign-in; Reddit threads cite ~$25/month for the Premium unlimited tier with a free tier available.

THE VERDICT
Feature-by-Feature Comparison
WHAT SUPRMIND ADDS
Beyond Side-by-Side Panes
Six modes, document deliverables, and decision tooling that build on the multi-model foundation.
Unique to Suprmind
Red Team Mode
4 attack vectors: Technical Feasibility, Logical Consistency, Practical Implementation, Mitigation Synthesis. Stress-tests whether an answer survives real-world conditions, not just whether models agree on it.
Unique to Suprmind
Decision Validation Engine
6-stage pipeline producing a GO / NO-GO / GO-WITH-CONDITIONS verdict with full FMEA-style risk register. For decisions where you need defensible reasoning attached to the answer, not just the answer.
Unique to Suprmind
Master Document Generator
25+ professional templates: Investment Memo, Executive Brief, SWOT, Legal Brief, Research Paper, Dev Brief. Auto-embedded Smart Visualizations in PDF and DOCX exports.
Unique to Suprmind
Adjudicator + DCI
DCI tracks every disagreement and correction in the conversation. Adjudicator reads the full thread, weighs the evidence, and produces an independent decision brief — reasoned commentary on which side to take and why.
Workspace Intelligence
Project Knowledge Graph
Automatically extracts entities, decisions, and relationships across conversations within a project. Master Project (Frontier+) extends this across the entire workspace so the 10th conversation is meaningfully smarter than the first.
Conductor Control
@Mention + Mode Chaining
Direct specific AIs to specific tasks: “@Perplexity gather the data, @Claude challenge it, @Gemini synthesize the brief.” Chain modes mid-conversation: Super Mind → Red Team → Adjudicator on a single question.
THE RIGHT FIT
Who Should Choose Which?
Choose ChatHub If:
-
—
You want a Chrome / Edge / Firefox / Safari browser extension that lives inside your existing tab so multi-AI comparison happens without context-switching to a separate web app -
—
Native iOS, Android, Windows, and macOS apps matter to your workflow, and a Progressive Web App install is not enough -
—
You already pay for ChatGPT Plus or Claude Pro and want to reuse those sessions via cookie passthrough rather than buying a separate plan -
—
Generative image creation in chat (Nano Banana, FLUX.2, Stable Diffusion) is part of your workflow -
—
Your work product is a chat answer or a quick comparison, not a deliverable document or a defensible decision
Choose Suprmind If:
-
+
Your work produces deliverables (memos, briefs, reports, recommendations) and output format matters as much as content quality -
+
Decisions in your work have consequences and need adversarial stress-testing (Red Team) and structured deliberation (Debate, First Principles) before you commit -
+
You want a synthesis layer on top of parallel multi-model query — a unified answer with consensus and divergence flagged, not raw outputs in split panes -
+
Cross-thread Project Knowledge Graph and Master Project would compound your research workflows over time -
+
EU and Switzerland data residency is a procurement requirement (Suprmind hosts in Germany with database in Switzerland) -
+
You need a Decision Validation Engine, Adjudicator, and Master Document Generator with 25+ export templates
FREQUENTLY ASKED
ChatHub vs Suprmind — Common Questions
Does Suprmind do everything ChatHub does on multi-model side-by-side comparison?
Yes. Both platforms let you run a single prompt across multiple frontier AI models in one interface and see the answers together. ChatHub displays raw outputs in split panes (single, 2-up, 3-up, or 2×2 grid). Suprmind’s Super Mind mode runs all five frontier models (GPT, Claude, Gemini, Grok, Perplexity Sonar on Pro+) in parallel and produces a synthesized answer with consensus and divergence flagged — plus the option to switch synthesis strategy (default Synthesis, Comprehensive, Consensus-only, or Adversarial). Same parallel-query pattern, with synthesis on top.
Is ChatHub cheaper than Suprmind?
Depends on the comparison. ChatHub has a free tier with limited usage and a Premium plan at roughly $25/month for unlimited access. Suprmind Spark at $4/month includes Super Mind, Sequential, @Mention orchestration, and the Scribe live note-taker — cheaper than ChatHub Premium for the parallel-comparison pattern alone. For the full mode set (Debate, Red Team, First Principles, Decision Validation Engine, Adjudicator, DCI, Master Document Generator), Suprmind Pro at $45/month is the right comparison and is structurally a different product than ChatHub’s chatbot client pattern.
How many AI models does each platform use?
ChatHub markets 20+ models with current frontier including GPT-5.5, Claude Sonnet 4.6, Gemini 3.1 Pro, Grok 4.3, DeepSeek-V4, Qwen, GLM, Llama, and MiniMax. Suprmind runs five frontier brands on Pro and above: GPT, Claude, Gemini, Grok, Perplexity Sonar — chosen as the strongest available from each provider, all running together in every conversation with structured collaboration modes. The trade-off is breadth of brand options versus depth of orchestration where each frontier model reads what the others said and builds on it.
Does Suprmind work as a browser extension like ChatHub?
No. Suprmind is a web app (suprmind.ai) with a Progressive Web App install option for iOS, Android, Windows, and macOS — you get an app-like icon and offline indicator, but it’s not a Chrome / Edge / Firefox / Safari extension that lives inside your existing browser tab. ChatHub’s browser-extension form factor is genuinely different and well-suited if you want multi-AI comparison without leaving the page you’re already on.
Does Suprmind have image generation like ChatHub?
ChatHub has generative image creation built in (Nano Banana, FLUX.2, Stable Diffusion). Suprmind has Smart Visualizations — auto-generated interactive charts (bar, line, heatmap, table) that embed inline in chat and auto-attach to PDF and DOCX exports through the Master Document Generator. Different capability for different work: ChatHub’s image generation is for visual content and creative output; Suprmind’s Smart Visualizations are for data and analytical deliverables.
What does Suprmind offer that ChatHub doesn’t?
Six orchestration modes versus ChatHub’s side-by-side layouts: Sequential (each model reads prior responses and adds its own layer), Super Mind (parallel synthesis with four strategies), Debate (formal argumentation with vote and minority opinions), Red Team (4-vector adversarial stress test), First Principles (strip assumptions and rebuild), and Research Symphony (multi-AI research pipeline, Enterprise). On top, Suprmind ships a Decision Validation Engine producing GO / NO-GO verdicts, an Adjudicator that writes independent decision briefs, DCI tracking, a Master Document Generator with 25+ professional export templates, Project Knowledge Graph, and Master Project for cross-workspace intelligence.
Can I move my ChatHub workflow to Suprmind?
Yes. Anything you do on ChatHub — multi-model side-by-side comparison, BYOK to OpenAI / Anthropic / Google, prompt library access, file upload and analysis, web search, local chat history — works on Suprmind. Use Super Mind for the parallel-comparison pattern, BYOK is supported on Pro+, the Prompt Library pattern maps to Prompt Adjutant plus per-project instructions. Optional next steps you don’t get on ChatHub: Red Team to stress-test answers, Adjudicator for an independent decision brief, Master Doc export.
Can I use both ChatHub and Suprmind together?
Yes — they fit different jobs. ChatHub is well-suited for in-browser quick comparisons: you’re reading an article, you want three AIs to weigh in without leaving the tab, and the extension is right there. Suprmind fits when the work product is a deliverable or the decision has consequences: structured deliberation modes, decision validation, and document export in 25+ professional formats. A consultant might use ChatHub for daily drive-by questions and Suprmind for client deliverables; a researcher might use ChatHub for brainstorming and Suprmind for the final synthesis.
Decision intelligence platform for professionals who can’t afford to be wrong.
Five frontier AIs, in the same conversation. They debate, challenge, and build on each other — you export the verdict as a deliverable.
Disagreement is the feature.
