The practical difference: Sintra's cost is nearly flat but its 250 credits are a tight ceiling for advanced actions. Lindy's cost grows with seats and use, but you can buy exactly the capacity you need.
Who each one fits
- Sintra: a solo owner who wants a social, copy, support and SEO assistant at once, with no setup beyond connecting accounts.
- Lindy: an owner or small team who wants an assistant inside Gmail, Slack and a CRM, running routines such as a morning briefing, and who is willing to teach it.
Where both leave a gap
Both can act on your behalf, and both describe approval as something you configure. If a wrong reply or post would cost you a customer, you may prefer a tool where nothing is sent or published until you approve it. That is the design of Full Circle: finished work lands in one approval inbox, scored by an independent quality check, and you approve, edit or decline. It does not send email or make calls, and it has no public API yet, so it is narrower than Lindy. See Full Circle vs Sintra, Full Circle vs Lindy, and why approval queues matter. If you are still deciding whether you need either, start with what an AI employee actually does. More options: Sintra alternatives and Lindy alternatives.
