Pros and cons

Assistly

Pros

  • Permanent free plan with 50 chats a month and no card required.
  • Setup is one line of code, with guides for the main website builders.
  • Answers in the visitor's language and trains on pages and uploaded files.
  • Human takeover, lead status tracking and email or phone alerts are on every plan.
  • Plain trust page covering hosting, encryption, two step sign in and data deletion.

Cons

  • Very new product (domain registered April 2026), with no public customer count or independent reviews found.
  • Paid billing is not open yet, so paid plan prices may still change.
  • Web only: no native mobile app or browser extension.
  • WhatsApp on the Free plan and each extra integration beyond the plan limit cost $19.99 a month; extra team members cost $19 a month.
  • Replies depend on OpenAI models, so chat content is sent to a third party.

Decagon

Pros

  • Offers a per-resolution pricing option where escalations are not charged.

Cons
