One agent replaces all 12 Sintra helpers
Sintra splits work across twelve named personas. Purple+ does the same jobs in one place — with shared context, no credit caps, and no $97 ceiling.

Why teams switch from Sintra
No free plan to start
Sintra charges $48.50/month before you can test a single helper, and $97/month to unlock all twelve. Purple+ is free forever — no card, no trial countdown, no money-back chase.
Context lost between helpers
Sintra's helpers run in separate chat threads, so handing work from Penn the copywriter to Soshie the social media manager means pasting context manually. Purple+ is one agent with one memory — every brief, brand voice, and asset stays in one place.
Built for agencies, not just individuals
Sintra is built around solo operators using prebuilt personas — only one of its twelve helpers (Soshie) touches social, and there's no client approval workflow, no multi-brand workspace, and no reels creation. Purple+ is built by Purple Media, a working social media agency — so multi-account scheduling, client approvals, and reels are first-class.
Credit caps that cut off mid-month
Every Sintra plan caps you at 250 credits per month, with top-ups required to keep going. Purple+ has no credit metering on the free plan.
