See it in action
Watch the council think
One question flows to four AI advisors, each with a unique perspective. Their insights are then synthesized into a single, superior answer.
Features
The AI second opinion for decisions that count
No single AI model gets it right every time. Synero cross-checks answers across models so you can act with confidence.
Cross-Model Verification
When four models from different labs agree, you can trust the answer. When they disagree, Synero surfaces the differences so you know where to dig deeper.
Intelligent Synthesis
A dedicated synthesizer reads every response, resolves contradictions, and produces one unified answer that's better than any model alone. Each template customizes how the synthesis is structured.
Council Templates
Purpose-built AI teams for every task. Select a template and the four advisors transform into domain specialists like Code Review, Due Diligence, Deep Research, and more.
Bring Your Own Keys
Free with your own API keys, or subscribe for $10/month and use ours. Mix both: use your keys for some providers and Synero's for the rest.
Persistent History & Private Mode
Searchable conversation history with a sidebar that lets you reload and continue past queries. Private mode keeps sensitive queries out of your history entirely.
API, MCP & Agent Frameworks
REST API with JSON mode, MCP server for Claude Code and Cursor, and tools for LangChain, CrewAI, and n8n. Build multi-model verification into any workflow.
