Pricing and Prompt Limits
Otterly.ai starts at €85/month for its starter plan, which includes 50 prompt trackings. If you need to monitor more prompts, higher tiers scale to €499/month with increased limits. The per-prompt cost can add up quickly for brands that want to track hundreds of queries across multiple AI models.
MentionFox starts at $99/month with unlimited prompt tracking in its GEO monitoring. There are no prompt caps or per-query charges. Combined with social listening across 50+ platforms, lead generation, contact enrichment, and email outreach, MentionFox packs significantly more functionality into a comparable price point.
For teams that only need to track a small number of prompts, Otterly's starter plan at €85/month is a cost-effective entry point. But as monitoring needs grow, the cost advantage can shift to MentionFox, which does not charge more for additional prompts.
Monitoring-Only vs Action Platform
Otterly.ai is a clean, focused GEO monitoring tool. It tracks how AI models reference your brand, shows visibility trends over time, compares you against competitors, and provides prompt scheduling for automated checks. The UI is well-designed and the experience is straightforward. It does one thing and does it well.
MentionFox is a broader platform that combines GEO monitoring with social listening, lead generation, contact enrichment, email outreach, and active GEO optimization. When MentionFox detects a problem in your AI visibility, Fox Promoter can actively work to improve it. When social listening finds someone discussing your product category, the lead pipeline can extract their contact information and help you reach out.
The trade-off is complexity. Otterly's focused approach means less to learn and fewer features to configure. MentionFox's broader platform means more capabilities but more surface area to manage. For solo marketers or small teams that want simplicity, Otterly's focus is appealing. For teams that want to consolidate tools, MentionFox replaces multiple subscriptions.
Prompt Scheduling: Otterly's Strength
Otterly.ai's prompt scheduling feature lets you set up automated recurring checks of specific prompts across AI platforms. You define the prompts, set the frequency, and Otterly runs them automatically, building a historical dataset of how AI responses change over time. This is particularly useful for tracking the impact of content changes, PR events, or competitor movements on AI recommendations.
MentionFox has more limited prompt scheduling capabilities for GEO monitoring. Its scheduling strength lies in social listening scans, which can run on daily, weekly, or monthly schedules across 50+ platforms. For teams that need precise prompt-level scheduling for GEO, Otterly's implementation is more mature.
When Otterly.ai Is the Better Choice
Otterly.ai is the right choice for teams that want a clean, focused AI visibility monitor without extra features. If you already have social listening, lead generation, and outreach tools in your stack, adding Otterly gives you dedicated GEO monitoring without overlap or complexity. The clean UI and straightforward workflow mean minimal onboarding time.
For agencies or consultants who need to show clients a clear, easy-to-understand GEO dashboard without the noise of additional features, Otterly's focused presentation is an advantage. The prompt scheduling feature is also genuinely useful for teams running structured GEO experiments or tracking specific queries over time.
