How are these Helpers better than ChatGPT?
How are these Helpers better than ChatGPT?
Sintra Helpers offer more than ChatGPT. Each helper is pre-trained and adapted for a role (copywriting, sales, SEO, social media, data), so you get relevant and actionable results. Sintra Helpers are powered by multiple greatest AI models.
Brain AI lets you create multiple business profiles, each acting as a context database, with everything you upload encrypted at-rest and in-transit. This way, every AI helper instantly understands your business context, and every campaign, report, or piece of content feels like it was crafted by someone who’s been on your team for years. You can share this knowledge base with teammates who also use Sintra, too.
Sintra connects directly with platforms you already use, with Gmail, Notion, Facebook and Instagram being just a few, so you can automate the boring stuff you now do manually.
