Extra and Sintra AI both offer a team of AI agents for small businesses, but they work differently. Sintra AI is a self-service tool from Lithuania with 12 “helpers” and an autonomous mode. Extra gives you eight agents connected to your tools, set up with you by an expert, and nothing goes out without your approval.
We make Extra, so this comparison is written by an interested party. Facts about other tools come from the public sources listed at the bottom of the page, as of the update date.

What is the main difference between Extra and Sintra AI?
The main difference is control. With Extra, each agent prepares the work (a reminder, a post, a reply to a review) and nothing goes out without your approval: you allow an action once, or always for a type of action, and you can take that back whenever you like. Sintra AI puts forward Sintra X, a mode that runs tasks in the background, even when you’re away. If you want to delegate without reading, Sintra goes further. If a clumsy reminder or a poor reply to a Google review can cost you a customer, Extra’s approval step is a safeguard.
How much do Extra and Sintra AI cost?
Extra costs $99 per month, with no commitment and 100 credits per month. A simple task (a post, a reminder, a reply to a review) uses one credit; a long task (an audit, a website) uses several. 50 more credits cost $45.
Sintra X is listed at $97 per month billed monthly, with lower prices on 3 and 12 months and frequent promotions: on October 19, 2026, its pricing page offered it at $48.50 for the first month, without saying what it costs after that. It includes 250 credits per month, which don’t roll over.
Which one is easier to set up?
Extra is built for business owners who have neither the time nor the wish to configure an AI tool. An Extra expert calls you, connects your tools (Gmail or Outlook, Stripe, Shopify, Instagram, your phone line…) and shows you how to hand over your tasks. Setup is included. Sintra AI is set up on your own, which suits you if you’re at ease with this kind of tool.
Which tools do they work with?
Extra’s agents work with Gmail or Outlook, Google Calendar, Stripe, Shopify, Google Business Profile, Trustpilot and your phone line: Jim, the reception agent, answers common calls and books appointments. Sintra AI advertises more than 100 languages.
