Everything the arena can do.
Sixteen models from nine providers share one thread — reading each other and replying. From a two-model gut-check to a full consensus debate to rewriting the result in your own voice.
Six ways to put the room to work
The same shared context, four lenses on it, plus a voice editor and automated pipelines on top.
Round Table
Pose a hard question and let multiple models debate it — proposing, voting, and building on each other until consensus emerges. Parallel and sequential execution modes, automatic agreement detection, and preset templates for code reviews, brainstorming, and research synthesis.
Pro & aboveEveryone Mode
Broadcast one prompt to every model at once and get parallel perspectives in a single conversation.
All plansCompare
Send a message to two models side-by-side and judge their answers head to head.
All plansNaturalize
Rewrite any AI draft into your own voice — six-grade depth control plus tone presets for emails, posts, and marketing copy that sound like you.
Pro & aboveMulti-agent Workflows
Chain models into pipelines — research, code review, and debate, automated end to end.
ColosseumUsage analytics
See which models you reach for, track credit consumption, and export the data. Know what's working and tune your workflow around it.
Pro & aboveBuilt to live in, not just demo in
Everything around the conversation — organization, context, and the people you work with — is first-class.
Conversation management
Folder-based organization, advanced search and filters, and export to PDF, JSON, or CSV. Rolling summaries keep long threads context-aware without losing the plot.
All plansTeam collaboration
Shared team workspaces, shared conversations, and role-based access — so a whole team can put the room to work on the same problem.
ColosseumEnterprise-grade
SAML SSO, audit logs, custom model integrations, dedicated infrastructure, and a 99.9% uptime SLA for teams that need it locked down.
EnterpriseMake any draft sound like you
The voice-match editor turns AI output into writing you'd actually send — for emails, posts, and marketing copy.
- Six-grade depth controlDial the rewrite from a light touch to a full re-voicing, sentence by sentence.
- Sentence-level flaggingTargeted edits on the lines that read as machine-written — fix only what needs fixing.
- Iterative refinementRe-run stubborn sentences until they land, without redoing the whole draft.
- Tone presetsAcademic, Professional, Casual, and Creative — match the register to the audience.

“Loved what you're building — I think there's a real fit here. Got 15 minutes this week to dig in?”
