The short version

  • Each has a real cost: FigJam organization and Enterprise tiers are billed annually only, with no monthly billing option; Sigil it produces no print output whatever, so any book that needs a paperback interior requires a completely separate tool and a second workflow.
  • They diverge on capability: FigJam covers Infinite whiteboard, Sigil covers Direct EPUB editing.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

FigJam

  • Organization and Enterprise tiers are billed annually only, with no monthly billing option
  • Free Starter plan caps AI credit usage at 150 credits per day and 500 per month, well below the 3,000 monthly AI credits on a Professional full seat

Sigil

  • It produces no print output whatever, so any book that needs a paperback interior requires a completely separate tool and a second workflow.
  • Meaningful use requires reading and writing HTML and CSS, which puts it out of reach of most authors who simply want a finished file.
  • There is no cloud storage, sync or collaboration, so the book exists as a file on one machine and version control is whatever you set up yourself.
  • Development depends on a small number of volunteer maintainers, so release timing and platform builds follow their availability rather than a roadmap, and a lapse in maintenance would leave no obvious successor.
  • It provides no distribution, no retailer connection and no Kindle-native output, so it sits in the middle of a workflow that other tools have to complete on both sides.

Answered from the vendors’ own pages

FigJam: Is FigJam included with Figma or sold separately?

FigJam is included at no additional cost with all Figma plans, from the free Starter plan through Enterprise.

Source
Sigil: Can I write my book in Sigil?

You can, but you should not. It is an EPUB editor, not a word processor, and writing long-form prose in it is unpleasant. Write elsewhere, import, then finish in Sigil.

FigJam: How many AI credits does each Figma plan include for FigJam?

The Professional plan includes 3,000 AI credits per month, Organization plan includes 3,500 AI credits per month, and Enterprise plan includes 4,250 AI credits per month. Starter (free) does not include AI features.

Source
Sigil: Does it make Kindle files?

Not natively. Produce a valid EPUB in Sigil and let Amazon convert it, or use a separate conversion tool for other Kindle formats.

FigJam: What can I do with FigJam's open sessions feature?

FigJam allows anyone to join open sessions for 24 hours without needing a Figma account, and you can create unlimited open sessions across your team.

Source
Sigil: Is it safe to rely on a volunteer project for commercial work?

The files it produces are standard EPUB, so nothing is locked in. The risk is that maintenance stops, not that your books become unreadable.

FigJam: What diagramming capabilities does FigJam include?

FigJam includes advanced shapes for technical diagramming such as AWS, GCP, Azure, and Kubernetes components, plus standard diagramming tools and connectors. All these features are available on every paid plan.
