Sintra and chyll start from the same promise: AI to help run your small business. But their philosophies differ sharply. One hands you a dozen predefined assistants, the other gives you a single brain that knows your whole business. Here is an honest comparison.
Sintra: the simplicity of a ready-made roster
Sintra offers a dozen predefined assistants, each with a role (sales, support, social media and so on). It is turnkey: you arrive, the profiles are there, you start.
Let's be fair, that is a genuine strength. If you are just starting out, having nothing to configure is reassuring. The approach is no-code (not a single line of programming), clear, immediate.
The trade-off: your business ends up split across twelve interlocutors. Each assistant sees its own slice of the job, and it is up to you to shuttle between them whenever a topic spills outside one role. It is also an American service, in English by default. If your need falls outside the planned scope, you adapt to the product, not the other way around.
chyll: a single brain that knows your whole business
chyll flips the logic. Instead of a catalogue of characters, you get one conversation with one business brain, plugged into your tools.
You connect your inbox, your invoicing, your calendar in one click (over 1000 integrations, with per-tool permissions you can revoke at any time). chyll learns your business once: your clients, your offers, your tone. That business memory powers everything, from quotes to chasing unpaid invoices, with nothing to explain twice.
Above all, chyll acts inside your tools: it spots unpaid invoices, prepares payment reminders, sorts emails, preps your meetings, even at night on autopilot. And you approve before anything is sent: nothing irreversible goes out without your agreement.
Sintra gives you twelve specialists who each see one piece. chyll gives you one brain that knows the whole house.

What to remember
Sintra shines through its immediate simplicity: if you want a ready-made kit of assistants in English, it does the job. chyll aims for something else for independents and very small businesses: a single brain that knows your whole business, acts inside your real tools, and asks for your approval before sending. The real question is not "how many assistants?" but "do you want to explain your business twelve times, or once?". chyll is in early access, opening in waves: join the waitlist at chyll.ai.
