Let AI disagree.
Then decide.
The simplest way to use it
Before you trust an AI answer, ask its competitors.
Ask ChatGPT to check its own answer and it tends to agree with itself. Parley has models from three different companies answer without seeing each other, then shows on one card where they agreed and where they split.
Paste
A question, another AI's answer, or a claim you read.
Check
Three companies' models answer independently. Nothing to set up.
Read the verdict
If they agree, that is evidence. If they split, that is exactly what to check yourself.
Agreement is not proof. What you see is whether three independent models reached the same conclusion.
One conversation. Multiple participants.
Not "ask GPT, then ask Claude, then compare." Everyone is in the same Room, and can call on each other directly.
Pick your models
Ten providers are available (GPT, Claude, Gemini, Grok, Mistral, Qwen, SEA-LION, Cohere, PLaMo, Solar). On the free and Credit plans, six of them are included and ready to use with no API key of your own: GPT, Claude, Gemini, Grok, Qwen and Cohere. The other four (Mistral, SEA-LION, PLaMo and Solar) need a key of your own, as does running any provider on your own account.
Open a Room
Every AI model and every person you invite becomes a Participant in the same conversation.
Let everyone talk
You and the AI Participants @mention each other and challenge assumptions. In Auto Mode, they can bring each other in on their own, within a budget you control, and turn to you directly the moment a call is truly yours to make.
Call for a Consensus
Any participant can flag that a summary would help. Agreement, disagreement, and uncertainty come back side by side, never forced into a false majority vote.
Three times you open Parley.
A single AI chat tends to just agree with you. Every piece of Parley exists to fix that.
The page you're reading, read three ways
Ask about whatever is open in your browser and three models from three companies read it separately. Where their readings part is the part worth a second look — and the part a single summary hides from you.
The decision you can't settle
"Raise the price or hold it." "Build auth or buy it." Questions where both answers cost something are the ones models actually split on, and where they split is usually what the decision really turns on.
The answer you're not sure you can trust
Paste what another AI told you and have models from other companies check it. A single model grading its own kind of answer is the known weak spot; several from different training are the usual fix.
See where the models actually agree
Broadcast one question to every model at once. Each answers on its own. Then Parley shows you the real overlap.
Deeper analysis, powered by multiple AI models.
Good data sources are the foundation. What Parley adds is the analysis that comes after: a report that writes itself as the conversation continues, with prose, data, charts, and a table updating turn by turn. It's trustworthy because every model researches independently, then checks and disputes what the others found, live in the dashboard.
Then decide, with everything on the table.
Any Participant can call for a Consensus summary: a structured snapshot of where the Room actually stands, not a forced majority vote.
Agreement
A vertical SaaS approach is the strongest starting point.
Disagreement
Gemini favors market size in India; Claude prioritizes distribution risk.
Uncertainty
Whether the target segment will pay before the product proves lock-in.
Open Questions
What's the minimum viable pricing tier?
Evidence
Two comparable vertical SaaS launches were cited as reference points.
Risks
Long enterprise sales cycles could stall early traction.
Next Steps
Ship a narrow MVP and validate it with ten target customers.
Ask several models about the page you're on.
The Chrome extension puts Parley in a side panel. Ask about the page in front of you and read what each model makes of it, without copying anything into another tab.
- Reads the page you're on, so you don't paste it anywhere.
- Starts a new Room when you change subject, so one browsing session doesn't become one tangled thread.
- Compare answers works here too, on every plan.
Working in Claude Code, Claude Desktop or Cursor? The AI there can ask Parley for a second opinion too. How to connect
Built for people who take their data seriously.
Your keys and your conversations, handled the way you'd want them handled.
Encrypted the moment it arrives
Every API key is envelope-encrypted with Google Cloud KMS before it's ever written to disk.
Never used to train anything
Parley relays your messages to the AI you chose. We don't retain them for training, ours or anyone else's.
Clear about what you pay for
On a Credit plan you pay Parley one predictable amount and we cover the inference. On your own key you pay the provider directly, and Parley never adds a markup on top.
Try it free. Pay for what you actually use.
Start free. Starter and up unlock everything — Auto Mode, Research, Brainstorming — the only difference is how much Credit you get. Bring your own API key for BYOK's fully unlimited access.

You don't need an API key to start: the free and Credit plans include GPT, Claude, Gemini, Grok, Qwen and Cohere. Add your own key to reach Mistral, SEA-LION, PLaMo and Solar, or to run any provider on your own account and pay that provider directly. Parley never marks up inference on your own key. Takes about a minute per model.

Why "Parley"
A parley is a conversation held between opposing sides to settle a dispute: not a vote, not a single ruling, but a negotiated understanding reached by talking it through. That is exactly what happens when GPT, Claude, Gemini, and Grok are placed in the same Room: they hold different positions, and the goal isn't to force them into agreement, but to let the discussion itself surface what's actually true, uncertain, or still contested.
Open a Room. Let them disagree.
Free to start, no credit card, ready in about a minute.
