Our verdict
KDAN suits small businesses that want to read and mark up PDFs at no cost before they ever pay for signatures. The free plan is the entry route, and its limits are Free plan: view and annotate PDFs, so the fit is document review rather than high volume signing.

The company behind it
KDAN is headquartered in Taiwan, which places the company in Taiwan. It was founded in 2009, so the vendor has been running for many years rather than being a new arrival in e-signature. For buyers comparing longer standing tools, the home market and founding date are the two details to weigh first.

Frequently asked questions
Does KDAN have a free plan?+
Yes. KDAN offers a free plan, and free plan is the model listed, so there is a no cost route in rather than a trial alone. Teams that mainly read and mark up documents can start there and look at higher tiers later.
What can I do on the KDAN free plan?+
The free plan is described as Free plan: view and annotate PDFs, so it covers opening PDFs and writing on them rather than dispatching documents for signature. In practice it reads as a review tool first, and anything beyond annotation would sit on a higher tier.
Who is KDAN built for?+
The stated audience is small business and enterprise, which runs from small businesses to enterprise buyers. The free plan suits a small team that only needs to review documents, while larger buyers are the ones more likely to need the higher tiers.
Where is KDAN based and how long has it run?+
KDAN is headquartered in Taiwan and was founded in 2009. The Taiwanese base and the long operating history matter for buyers who want a vendor with a track record, and both sit alongside the free plan in the buying decision.
How does the KDAN free plan compare with eSignly?+
eSignly's free tier reaches into signing as well, with limits listed as Free plan: unlimited signatures, 5 MB. KDAN's free plan is Free plan: view and annotate PDFs, so a team that must dispatch documents may find more room on the eSignly tier.
Is there a free tier at Privy.id or DocuSign?+
Privy.id sets a stated free limit of 10 docs/month on Free plan, while DocuSign has no free plan. A no cost starting point therefore exists at Privy.id but not at DocuSign, which is worth knowing if budget at sign up matters.
What kind of software is KDAN?+
KDAN is listed in the e-signature category as e signature, and the free plan points at document work rather than contract sending. Buyers comparing signature suites should weigh the annotation focus of the free tier before looking at what a higher tier adds.
