One conversation.
Multiple minds.

Stop talking to a single AI. Roundtable AI orchestrates a structured debate between multiple models — giving you richer analysis, genuine disagreement, and synthesised conclusions you can trust.

Multi-Agent Orchestration

A round table, not a chatbot

Most AI tools give you one model, one voice. Roundtable AI seats up to 8 AI agents around a shared conversation — each with a distinct persona, model, and perspective. They respond to each other, challenge assumptions, and build on what came before. The result reads more like a brainstorming session than a Q&A thread.

  • Seat 2 to 8 agents per session — mix and match models freely
  • Round Robin mode: structured, equal participation from every voice
  • Moderator mode: a designated agent decides who speaks next
  • Real-time streaming — watch each agent think token by token
  • Full session history saved automatically, resume any time

Director Controls

You're always in the room

Roundtable AI doesn't run on autopilot. You stay in control at every step. Pause after any turn, inject context as the Director, redirect the conversation mid-session, or ask one specific agent to elaborate on a point. When you're satisfied, trigger a synthesis and get a structured conclusion from the agent of your choice.

  • Pause and resume sessions at any point without losing state
  • Inject "Director" messages visible to all agents as shared context
  • Ask any agent to elaborate on a specific point
  • Force conclusion: pick which agent synthesises the debate
  • Export full sessions as Markdown, JSON, or HTML

How It Works

A round table running
in under 60 seconds

No configuration hell. No API wrangling. Follow three steps and your AI panel is already talking.

1

Connect your models

Point Roundtable AI to your local GGUF files, enter your OpenRouter API key, or both. The app detects your hardware and recommends how many models you can run simultaneously. One-time setup, remembered forever.

2

Seat your agents

Choose from built-in personas — Analyst, Devil's Advocate, Optimist, Fact Checker, Domain Experts — or create your own. Assign a model to each agent, pick a discussion mode, and set your goal.

3

Watch them think

Each agent responds in turn, building on what came before. Inject context, redirect the conversation, ask someone to elaborate, or force a conclusion. Export the full session when you're done.

FAQ

Frequently asked

Yes — Roundtable AI ships without bundled models to keep the app lightweight. For local inference, you download your preferred GGUF models separately (from Hugging Face or similar). Recommended starting point: any 3B or 7B model in Q4_K_M format. For cloud models, just enter your OpenRouter API key and you're ready immediately — no separate downloads needed.
For a meaningful multi-agent experience with local models, we recommend at least 16 GB of unified memory (M1, M2, M3 or M4 chip). With 16 GB you can comfortably run two 3B models simultaneously. With 32 GB, you can seat 3–4 agents on 7B models. With 8 GB it's tight — we'd suggest using OpenRouter for cloud models instead, which have no local RAM requirements.
When using local GGUF models, nothing leaves your Mac — ever. All inference happens on-device. When using OpenRouter, your conversation messages are sent to the respective cloud model provider (just as they would be if you used that model's own interface). No conversation content is ever sent to HighRoad Software. Your sessions are stored locally in a SQLite database on your Mac.
Absolutely. Every built-in persona can be duplicated and customised. You can change the name, upload a custom avatar, write a role description, set a debate style (aggressive, balanced, cautious, creative, analytical), adjust the temperature, add expertise tags, and even write a full custom system prompt for complete control over the agent's behaviour. Custom personas are saved and reusable across sessions.
Roundtable AI launches with two turn-flow modes: Round Robin (agents speak in fixed order) and Moderator (a designated agent decides who speaks next based on relevance). Additional modes — Popcorn (speaker nominates next), Most Relevant (scored by expertise), and Free-for-All (all respond simultaneously) — are coming in v1.1.
Yes — Roundtable AI is completely free to download and use. There are no subscriptions, no account required, and no usage limits on the app itself. If you use cloud models via OpenRouter, you pay OpenRouter directly at their standard rates (typically fractions of a cent per message). Local model usage has no cost beyond your hardware.
