Let AI disagree.
Then decide.
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, seven of them are included and ready to use with no API key of your own: GPT, Claude, Gemini, Grok, Qwen, Cohere and Solar. The other three (Mistral, SEA-LION and PLaMo) 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.
Built for genuine disagreement.
A single AI chat tends to just agree with you. Every piece of Parley exists to fix that.
Real disagreement, not agreement theater
A single AI tends to agree with whoever it's talking to. Parley's Participants push back on each other, and on you, when an argument doesn't hold up.
Assign roles, not just prompts
Skeptic, Advocate, Premise Challenger: give each AI a distinct job before a Brainstorming Room starts, so the disagreement is structured instead of random.
A second model checks the claim
Before an answer settles, another Participant can peer-review it and fact-check what it asserted. Disagreement is only useful if someone verifies who was right.
Consensus, not a blended answer
See where the group actually agrees and where it splits, instead of one smoothed-over response that papers over real disagreement.
Deep Research
Participants can search the web and cite their sources when it's genuinely useful, so disagreement is grounded in evidence, not just style.
The conversation becomes a document
Models draft a shared document section by section as you talk, review each other's sections, and you export the result to Word or Google Docs.
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.

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.

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.
