Sintra gives you AI employees. PureBrain gives you an AI partner that actually knows your business.
See the real differences ↓
Hiring AI employees sounds great on the landing page. But what happens when those employees cannot remember yesterday’s meeting?
I set up an AI sales rep to handle leads. Every new conversation, it had no idea what we sell or who our customers are. I was re-briefing it constantly.
-- SaaS Founder, 15-person team
The AI HR employee wrote a policy doc that completely contradicted what we agreed on last week. It had no memory of the previous version.
-- Operations Director, Growth company
12 AI employees sounds like a deal until you realize none of them talk to each other. The marketing bot has no idea what the sales bot is saying.
-- CEO, E-commerce brand
These are not feature gaps. They are architectural differences that change what AI can do for your business.
Sintra’s AI employees start every task from scratch. PureBrain remembers every conversation, every decision, every preference -- and builds on them. Month 6 is dramatically smarter than month 1.
Sintra’s 12 employees work in complete isolation from each other. PureBrain’s 30+ agents share knowledge in real time -- when marketing learns something, sales knows it instantly.
PureBrain gets measurably smarter every week. It learns your patterns, your voice, your decision-making style. Sintra delivers the same baseline capability on day 365 as day 1.
Sintra offers generic employees with surface-level skills across broad categories. PureBrain agents are deeply specialized -- trained on your specific industry, your workflows, your standards.
Sintra is task execution -- give it an order, get output. PureBrain is a thinking partner that understands your business context, challenges your assumptions, and proactively surfaces insights you did not ask for.
This is not about who has more features. It is about fundamentally different approaches to AI.
