KAIUS starts at EUR 19/user/month, AI included. Secib is listed from EUR 89 excl. VAT/user/month, without the Septeo Brain AI layer. The entry-price gap exceeds EUR 70 per user per month.
No. Septeo Brain is an add-on AI layer sold separately from Secib. KAIUS embeds the AI assistant and AI drafting natively, with no extra module.
KAIUS publishes its rates on its website. Secib sells most offers by quote, which slows down decisions and makes comparison harder.
KAIUS is an independent vendor focused on legal AI, able to ship fast. Secib sits inside a large multi-product group's roadmap, with longer release cycles.
