One prompt.
Four perspectives.
A clearer answer.

Coordinate ChatGPT, Claude, Gemini, and Grok from one focused Side Panel. Multi-AI Chat uses the tabs you are already signed into—no model API keys and no separate chat backend.

  • No model API keys
  • No developer server
  • No tracking or telemetry

Five ways to think

Choose the conversation, not the plumbing.

Compare answers in parallel or let the models challenge, review, and refine one another in a structured sequence.

01

Free

Send to every selected, ready provider in parallel. The fastest way to compare independent answers.

You → selected AIs
02

Debate

Assign opposing positions, ask a judge to weigh them, then synthesize the strongest result.

Pro → Con → Judge → Synthesis
03

Consult

Gather two independent answers, have another AI review them, then produce one final response.

2 answers → Review → Final
04

Coding

An eight-step loop for specification, review, implementation, testing, revision, and acceptance.

Plan → Build → Test → Accept
05

Roundtable

Four AIs build on the shared discussion across five rounds—twenty contributions in total.

5 rounds × 4 AIs

Built for the imperfect web

A failed turn does not have to end the table.

If a provider fails during Roundtable, the run pauses and gives you three explicit choices.

  1. RetryStart a clean request with a fresh ID.
  2. Skip this turnContinue with a safe placeholder, never the provider's error text.
  3. CancelStop the workflow and reject active waiters.

Small panel, deliberate engineering

Reliable enough for real workflows.

Connection recovery

Provider tabs are rediscovered after service-worker restarts, and packaged content scripts are repaired when needed.

Request isolation

Each request has its own ID, so a late answer cannot complete the wrong step or a later workflow.

Honest readiness

A provider becomes Ready only after its composer confirms that the signed-in page can accept input.

Local by default

Settings and up to 30 conversations stay in Chrome. Follow up, start fresh, or remove the extension to delete its storage.

Private by architecture

Your conversations are not our product.

There is no Multi-AI Chat backend, analytics, tracking, advertising, or telemetry. Prompts go directly to the provider pages you select.

Read the full privacy policy

What stays local

Interface settings, up to 30 conversations, and an optional HackMD token live in chrome.storage.local. Provider content scripts cannot read that token.

What the extension accesses

sidePanel, tabs, scripting, and storage; host access is limited to ChatGPT, Claude, Gemini, Grok, and—only when you publish—api.hackmd.io.

What leaves your device

The prompts you send to selected providers, plus the current conversation and your own token only if you explicitly publish to HackMD. Nothing is sent to the developer.
