Editor's takeGlide connects to Google Sheets, Excel, Airtable, and SQL databases and syncs data in real time, per its pricing page. G2 reviewers call it the simplest way to build an internal tool in half an hour. The Business plan includes only 30 users at $199 a month, and updates beyond 5,000 a month add $0.02 each.

Can Glide apps work offline?

Partially. Business-plan users can view cached data and add new rows offline, but cannot edit existing data. The app must open online first to cache content.

PricingFrom $19/agent/mo, Advanced AI adds $50/agent/mo

Editor's takeZendesk Guide ties directly into Zendesk's ticketing system, giving support teams one workspace for tickets and articles. The 2025 Gartner Magic Quadrant named it a leader, and its 11.3% market share reflects wide adoption. Costs climb fast once Advanced AI and HIPAA compliance get added, both gated behind paid tiers.

Does Zendesk Knowledge Base support HIPAA compliance?

Only on the Enterprise plan. Customers using Zendesk for HIPAA use cases must sign a Business Associate Agreement and often buy the Advanced Security add-on, according to Zendesk's compliance documentation.

How big can a Zendesk help center article be?

Each article is capped at 1MB per translation, about 1 million characters, and accounts can hold up to 40,000 total articles, per Zendesk's product limits page.

8.2

Usability & Customer ExperienceLooked for: We examine the ease of setup, interface design, and the technical skill required to customize the help center for a branded experience.While the agent workspace is generally praised for unifying channels, the Help Center (Guide) customization relies on a proprietary templating language called 'Curlybars,' requiring developer resources for bespoke designs. Users also report a steep learning curve for advanced features and describe the interface as sometimes 'clunky' or 'outdated'.zendesk.com support.zendesk.com desk365.io
