ResponseSource vs Sistrix in 2026: UK journalist enquiries vs the European Visibility Index standard
ResponseSource earns UK press coverage through direct journalist requests. Sistrix is the credibility benchmark for European SEO, built around its proprietary Visibility Index. Neither monitors AI model visibility.
ResponseSource
Sistrix- ResponseSource has no keyword tracking or Visibility Index equivalent. Sistrix has no journalist database or press release wire.
- Sistrix's API is available on all five of its plans, starting at €119/month. ResponseSource has no API on any tier.
- Neither tool tracks AI model visibility: Sistrix lists AI model tracking as unavailable across every plan, and ResponseSource has no AI monitoring feature at all.
- Sistrix includes AI-powered content creation tools tied to keyword and ranking data. ResponseSource's only content feature is press release distribution through its wire service.
- Neither tool offers white-label client reporting: Sistrix explicitly lacks it across all tiers, and ResponseSource has no reporting branding feature at all.
ResponseSource and Sistrix share a category tag but serve different regions and different jobs. ResponseSource is a UK media relations platform where journalists post live requests for expert comment through the Journalist Enquiry Service, and PR professionals respond directly. Sistrix is a European SEO platform best known for its Visibility Index, a proprietary score that weights keyword rankings against search volume and has become a trusted benchmark among SEO professionals in the DACH region and beyond. Sistrix also covers technical audits, competitor intelligence, and AI-powered content creation, and its API is available across every plan. Neither tool monitors AI model visibility across ChatGPT or Gemini: Sistrix says so directly in its own pricing table, and ResponseSource has no search or AI monitoring capability at all.
The tools at a glance
ResponseSource
UK media relations platform connecting PR professionals with journalists seeking expert comment
ResponseSource has run the Journalist Enquiry Service for over twenty years, connecting UK journalists actively working on stories with PR professionals who can supply expert comment, data, or product information. This reverse-pitch structure tends to produce more targeted coverage than cold outreach.
The platform rounds out with a UK journalist database, a press release wire, and basic coverage monitoring. There is no organic search functionality of any kind, and the tool has almost no relevance outside the UK and Irish markets.
All three tiers require a sales conversation with no published pricing, and there is no API for pulling data into external systems.
| Feature | JES Only Contact | Journalist Database Contact | Full Suite Contact |
|---|---|---|---|
| Journalist Enquiry Service | Yes | ||
| Visibility/ranking metric | No | ||
| API access | No | ||
| Content creation tools | Press release distribution only |
Sistrix
Professional SEO platform with the Visibility Index, competitor intelligence, and AI-powered content tools
Sistrix is the dominant SEO platform across the DACH region and much of Europe, anchored by the Visibility Index, a proprietary score that weights keyword rankings against search volume into a single comparable metric. SEO professionals cite it regularly as an industry benchmark for tracking organic performance and competitive standing over time.
Beyond the index, Sistrix covers technical site audits, competitor analysis with historical depth, AI-powered content creation tied to keyword and ranking data, and monitoring for Amazon and Instagram from the Plus plan upward. The API is available across all five plans and is well-documented, which has made Sistrix popular with technical SEO teams building custom tooling.
Sistrix does not include white-label client reporting on any tier, and its own pricing table lists AI model tracking as unavailable across every plan. Pricing is Euro-denominated and sits toward the higher end, starting at €119 per month with no free tier.

Neither tool tracks AI model visibility. Here is what does.
Sistrix's own pricing table lists AI model tracking as unavailable on every one of its five plans, and ResponseSource has no AI monitoring feature since it is built for journalist outreach rather than search. If tracking your brand across ChatGPT, Gemini, Perplexity, and Google AI Overviews is part of your reporting requirements, AI Peekaboo covers those five engines with a read and write API included on every plan from $50 per month, plus white-label delivery, which neither Sistrix nor ResponseSource offers at any price.

ResponseSourceSistrixSistrixResponseSourceSistrixThis pairing reflects shared category tagging more than genuine competitive overlap. ResponseSource has zero organic search functionality, and Sistrix has zero PR or journalist outreach capability. Where they do genuinely overlap is a shared gap: neither tracks AI model visibility, and neither offers white-label client reporting, which matters for agencies delivering branded deliverables.
Bottom line
Go with ResponseSource for UK earned media through direct journalist relationships. Go with Sistrix if you need the Visibility Index benchmark, strong API access, and AI-assisted content tools grounded in European search data. Since neither tracks AI model visibility or offers white-label reporting, plan to pair whichever you choose with a dedicated tool covering those gaps if they matter to your programme.
Frequently asked questions
Do ResponseSource and Sistrix serve the same purpose?
No. ResponseSource is a UK media relations platform for earning press coverage through journalist enquiries, while Sistrix is a European SEO platform built around the Visibility Index metric. They share a category tag on review sites, but a team weighing them against each other is usually mixing up PR tooling and search tooling.
Does Sistrix track AI visibility in ChatGPT or Gemini?
No. Sistrix's own pricing table lists AI model tracking as unavailable across all five of its plans, from Start at €119 per month up to Enterprise. ResponseSource also has no AI tracking capability, since it is built for journalist outreach rather than search monitoring.
What is the Sistrix Visibility Index and does ResponseSource have anything similar?
The Visibility Index is a proprietary Sistrix score that weights keyword rankings against search volume into a single number representing a domain's overall Google presence. ResponseSource has no equivalent metric since it does not track organic search performance at all; its closest analogue is basic coverage monitoring for press pickup.
Which tool offers white-label reporting for agencies?
Neither does. Sistrix does not include white-label branded reporting on any of its five plans, and ResponseSource has no reporting branding feature either. Agencies needing branded client deliverables from either platform would need to build that layer themselves or use a separate reporting tool.
Is Sistrix a good fit for a UK-only PR-focused agency?
Not for the PR side of the work. Sistrix is strongest for European organic search performance, particularly in DACH markets, and has no journalist database or press outreach functionality. A UK PR-focused agency would still need ResponseSource or a comparable media relations tool for earned coverage, using Sistrix only if organic SEO is also part of the client scope.
