Otterly has been around since 2023 and has built a solid reputation for GEO audits. GenRank is newer to the space but offers something Otterly doesn't: a permanent free tier.
Established tooling vs. accessible entry point. Different trade-offs depending on where you are in your AI visibility journey.
Pricing and access
Otterly's Lite plan starts at $29/month for 15 prompts across 4 LLMs (ChatGPT, Perplexity, Copilot, AI Overviews). Standard at $189/month gives you 100 prompts with unlimited workspaces. Premium at $489/month offers 400 prompts. Some platforms like Gemini require paid add-ons.
GenRank offers a free tier with 10 prompts on ChatGPT, no credit card required. Their paid tiers expand coverage, though specific pricing varies.
That free tier is GenRank's differentiator for anyone who isn't sure yet whether AI visibility tracking is worth paying for. Otterly offers a 7-day trial, but that requires commitment. GenRank lets you test indefinitely.
Where Otterly stands out
Otterly's GEO audits analyze 25+ on-page factors. They don't just tell you whether you're visible in AI recommendations. They tell you why you're not and what specific changes to make. That's actionable guidance GenRank doesn't provide.
Otterly also tracks 4 LLMs at base price compared to GenRank's ChatGPT-only free tier. Broader platform coverage gives you a more complete picture of AI visibility.
For agencies managing multiple clients, Otterly's workspace organization provides clean separation and management at the Standard tier.
They have an established track record serving agencies and marketing teams since 2023. That matters if you value proven tooling.
Where GenRank stands out
The free tier is GenRank's main advantage. Ten prompts on ChatGPT without paying anything, without entering a credit card, without time limits. That's genuinely accessible for anyone exploring whether AI visibility tracking matters to their business.
GenRank includes competitive intelligence even on the free tier, so you can see how competitors perform in AI recommendations alongside your own results.
They also track citations, showing you which sources drive AI mentions. Understanding that attribution can inform content strategy.
Which one fits you?
Otterly makes sense if GEO audits (understanding why you're invisible, not just whether you are) would help your optimization work, you need 4+ LLMs tracked from the start, you're managing multiple clients and need workspace organization, you want established tooling with a track record, and you're ready to invest in GEO optimization.
GenRank makes sense if you want to test AI visibility tracking for free before committing money, ChatGPT is your primary concern right now, you're not sure yet whether GEO matters to your business, budget is tight, and trying before buying is important to you.
The bottom line
Otterly is more comprehensive. GenRank is more accessible.
If you know AI visibility matters to your business and you want specific guidance on how to improve it, Otterly's audits provide real value at $29/month.
If you're not sure yet whether AI visibility is relevant to your situation, GenRank's free tier lets you test the waters without any commitment.
Want 5 LLMs? Mentionable offers AI visibility tracking with a 7-day free trial and prompt suggestions. More coverage than GenRank's free tier, simpler than Otterly's audit-focused approach.
