Suprmind
Most multi-model tools fan a prompt out and show you four answers side by side. This one chains them, so each model argues with what the last one said, and the debate and red-team modes make that explicit. For a decision you are going to defend in writing, that plus templated export is a genuinely different workflow. The cost is that you are paying a markup on models you may already subscribe to, and only the 195-dollar tier lets you bring your own keys.
Pros
- Sequential mode means each model reads and responds to the earlier answers
- Debate, red-team and first-principles modes on top of the default flow
- Project workspaces with file uploads and per-plan size limits
- Export to more than twenty document templates as Markdown, PDF or DOCX
- Seven-day trial with no card, and bring-your-own-keys on the top self-serve tier
Cons
- Entry tier is limited to four providers and six models, and locks the extra modes
- Bring-your-own-keys only appears at 195 dollars a month
- No API, so this cannot be wired into anything else
- The company names no legal entity or country; billing runs through a third-party merchant of record
