Vaylis vs Otterly.AI: Which AI Search Monitoring Tool Gives You Deeper Insights for the Money?
Marketing teams can no longer rely on classic SEO dashboards alone; they need to understand exactly how AI models like ChatGPT, Perplexity, and Google AI Overviews mention, cite, and describe their brands. Two rising contenders promise to solve that problem: Vaylis and Otterly.AI. This head-to-head review breaks down where each tool shines—and where hidden costs or data gaps lurk.

|---|---|---|---|
| Lite | $29 | 15 | Core engines only |
| Standard | $189 | 100 | +$99 per extra 100 prompts |
| Premium | $489 | 400 | +$99 per extra 100 prompts |
| Gemini Add-on | $9–$149 | — | Adds Google Gemini coverage |
| AI Mode Add-on | $29–$489 | — | Adds Google AI Mode coverage |

Feature Deep-Dive
1. Platform Coverage & Tracking Logic
Vaylis pushes identical prompts to ChatGPT 4o Search, Perplexity, and Google AI Overviews, then stores the entire answer JSON plus a screenshot. This lets teams mine tone, entities, citations, and even hallucinations day-over-day.
Otterly.AI also uses prompt lists but grabs a screenshot and parses brand mentions, sentiment bars, position, and linked URLs. It does not expose the raw answer text for custom NLP work, but its interface surfaces the most practical fields (links, brands, sentiment).
Verdict: If you need raw answer text for deep content audits, Vaylis wins. If link citation tables and sentiment scores suffice, Otterly covers the basics.
2. Analytics Depth
| Metric | Vaylis | Otterly.AI |
|---|---|---|
| Full answer archive | ✅ | ❌ |
| Brand sentiment | ✅ | ✅ |
| Link citation grid | ✅ | ✅ |
| GEO technical audit | Basic | Detailed 25-factor audit |
| Weekly trend e-mails | ✅ | ✅ |
| Multi-country prompts | ✅ | ✅ |
Otterly’s built-in GEO Audit surfaces robot.txt issues, llms.txt hints, schema gaps, and other technical blockers specific to AI crawlers—a nice bonus for hands-on SEO teams.
3. Daily Tracking Cadence
Both tools default to daily crawls, capturing each engine’s freshest answer. Otterly notes that first-run data takes ~4 minutes per prompt; Vaylis’ API delivers results in under 60 seconds, which matters if you need near-real-time QA after content changes.
4. User Experience
Vaylis: AI-search-only UI, no distractions from classic keyword SEO. Guided onboarding and live chat.
Otterly.AI: Playful “otter” UI, wizard-based prompt import, and a Semrush-embedded version for agencies already living inside that ecosystem.
Cost Scenarios
| Scenario | Monthly Cost Vaylis | Monthly Cost Otterly |
|---|---|---|
| Track 50 prompts / day on 3 engines | €119 (Starter) | ~$29 Lite → fails (15 prompts) so $189 Standard |
| Track 150 prompts / day on 5 engines incl. Gemini | €289 (Growth) | $489 Premium + $9 Gemini = $498 |
Vaylis scales linearly by prompt count. Otterly’s leap from 100→400 prompts is steep; add-ons for each extra engine inflate the bill quickly.
