You want a chat window with one strong model, your team uses AI for one-off prompts more than persistent workflows, you don't need calendar/email integration, and you have no appetite for a third tool. They're great at what they are.
You want one operating layer your whole organization shares, with persistent context, multi-model routing, industry-specific advisors, and the option to ship engagement-grade AI workflows ($75K install) that move real metrics. You care that 10–15% of every dollar funds mission work.
Many of our customers keep ChatGPT Teams or Claude for Teams for one-off prompts, and add Perpetual Core for the persistent organizational layer. The Pro tier is $99/month and you can bring your existing API keys. No contract, no migration tax.
