The short version

  • Each has a real cost: Capacities pro plan pricing not prominently displayed on website; SignWell the free plan stops at three documents a month, which makes it a trial rather than a tier, so any genuine use converts to a paid seat within weeks.
  • They diverge on capability: Capacities covers Object-based notes, SignWell covers Per-sender pricing.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Capacities

  • Pro plan pricing not prominently displayed on website
  • Smaller community and ecosystem compared to Notion or Obsidian
  • Limited third-party integration marketplace

SignWell

  • The free plan stops at three documents a month, which makes it a trial rather than a tier, so any genuine use converts to a paid seat within weeks.
  • Pricing is per sender, so an organisation where many people occasionally need to send something either buys seats for staff who send a handful of documents a year or funnels everything through one person and creates a bottleneck.
  • Templates are rationed by tier, at one on free and five per sender on the entry plan, and templates are what makes the tool worth using at all, so the practical entry point is a tier above the headline price.
  • It is a smaller vendor in a category where signed agreements must be retrievable years later, so the safe practice is downloading every signed document and its audit certificate into your own storage rather than relying on the account still existing.
  • It provides standard electronic signatures rather than acting as a qualified trust service provider, so any transaction requiring a qualified electronic signature under European rules needs a different supplier alongside it.

SignWell: Is an electronic signature legally binding?
