Before you choose
Start with the pricing model
Look for a free plan if you need to begin without a subscription. A free trial can help you assess a paid workspace before committing.
Published examples show different entry points: ProProfs Knowledge Base lists a free plan, paid service from $0.99 per user per month on annual billing and a 15-day trial. Pearltrees lists a free plan and paid service from $2.99 per month.
Match the platforms you use
Check support for web, API, Windows, iOS, Android and macOS. A web app may suit browser-based work, while an API can connect knowledge to other software.
Check how people find answers
Compare the presence of AI search with the way your team expects to find information. Review supported content types before moving material into a new system.
Review access controls
Single sign-on can connect sign-in to an existing identity system. Granular permissions can help separate readers, editors and administrators. Confirm the controls match your workspace structure.
Consider change tracking
Version history can help you review or restore earlier content. Check how the feature is described for the documents and other content types you plan to manage.
Use a trial when available
Trial terms vary by product. DEVONthink lists a 30-day trial and a starting price of $99, while ProProfs Knowledge Base lists a 15-day trial. Check the maker's current terms before signing up.
