A few of the places InkSTR and Soro genuinely differ.
| Where it matters | InkSTR | Soro | Why it matters |
|---|---|---|---|
| Entry pricing | Starts at $99/mo for roughly 30 articles/mo | Starts from $39/mo, with 30 articles/mo at the entry tier | Soro wins on price at this tier; the gap is what's built around the article, a topic-cluster strategy versus a daily drip, and PMS data for STR operators, neither of which Soro's site describes. |
| Feature gating | Higher tiers add AI Strategist, content refresh, PMS integrations, and GEO tooling | Every plan includes the full feature set: keyword research, auto-linking, images, publishing | Soro's flat feature set is genuinely simpler to reason about; InkSTR's tiering reflects that PMS integration and scheduled content refresh are meaningfully deeper features than daily publishing, not artificial gating. |
| CMS coverage | Wix, WordPress, or any site via API (Claude and Lovable included), plus InkSTR's own hosted blog | WordPress, Shopify, Webflow, Notion, HubSpot, Ghost, Wix, and Next.js | Soro lists more named integrations; InkSTR's universal API path covers the same ground plus custom and AI-built sites (a Claude or Lovable build) that a named-integrations list can't anticipate. |
| Multi-project management | Separate strategy, calendar, and credentials per project, run from one dashboard | Not documented as a multi-site management feature | Running more than one brand or client site means each one needs its own detected business model and writing rules — a single connected-site setup has no place to keep that separate. |
| Business-model logic | Dedicated writing rules per business type, detected automatically from your site | One brand-voice profile per connected site | A brand-voice profile controls tone; InkSTR's business-model detection also controls what counts as a fabricated claim, which CTAs are allowed, and how competitors can be named — different problems that a voice profile alone doesn't solve. |
| PMS / STR integration | Connects to Hospitable, OwnerRez, and Hostaway — real guest reviews, occupancy data, and property details flow directly into articles | Not something Soro's site describes as a feature | InkSTR is the only platform in this comparison built specifically for STR/vacation-rental operators this way — a use case a generic daily-article tool has no reason to build for. |
