Relevance AI vs Sintra

Relevance AI

A credible no-code agent builder with a wide library of ready-made sales and ops agents, but the free tier is gone and the self-serve prices live on a docs page while the marketing site pushes everyone to a sales call. The two-meter billing — Actions plus pass-through Vendor Credits — makes running cost hard to forecast, and the $19 annual Pro plan only covers one project and two builders.

Pros

• +Agents get tools, knowledge and schedules without any code
• +Large library of pre-built agents for sales, support, HR and ops that can be customised
• +Model cost is passed through on vendor credits rather than marked up
• +Agents can be grouped into teams that hand work between each other

Cons

• −No free plan any more, only paid Pro and Team or an Enterprise quote
• −Two simultaneous meters make budgeting awkward and surprises likely
• −Top-up rates are steep at $80 per 1,000 actions
• −Pro is limited to one project and two build users, so a second workspace means the $349 Team plan

Sintra

Framing assistants as roles instead of prompts is a real usability idea for owners who do not want to think about prompt design, and the account integrations mean output goes somewhere rather than into a clipboard. What should slow you down is the pricing: the same 50-to-70-percent discount has sat on the page long enough to be the actual price, and the cheapest rate needs a year up front from a company whose only published address is a Delaware registered agent.

Pros

• +Assistants are scoped to job roles, which removes most prompt design
• +Connects to Gmail, Outlook, Google Calendar, Drive, Notion, Facebook and Instagram
• +One subscription covers every role rather than billing per assistant
• +14-day money-back guarantee

Cons

• −Permanent-looking discount pricing makes the real cost hard to judge
• −The cheapest rate needs twelve months paid in advance
• −No free tier at all
• −Company details stop at a Delaware registered-agent address
