Key takeaways
- Promptwatch is the pick if you want monitoring plus actual execution: crawler logs, content gap analysis, and Content Agents that write and publish GEO content to your CMS. Starts at $95/mo.
- AthenaHQ now has a genuinely free tier (300 credits/mo, 5 models), which makes it the cheapest way to test the category with real multi-model coverage.
- Otterly.AI is the budget option at $29/mo, but the advertised price is misleading once you add the engines (Gemini, Claude, AI Mode) that aren't included by default.
- Profound and Scrunch AI are built for bigger budgets and enterprise-y needs, agent traffic attribution and predictive citation scoring cost real money to unlock.
- Semrush's AI Toolkit makes sense only if you're already paying for Semrush; on its own it's a thin, expensive add-on that a lot of users say isn't worth $99/mo.
MentionBird's whole pitch is refreshingly narrow: it shows you the sources AI cites for a prompt, then gives you a ranked to-do list to get into those sources. That's useful, and it's cheaper to start ($79/mo vs. $99+ for most rivals) than a lot of the category. But it also has real limits. There's no free trial at all, since MentionBird charges for every prompt run to prevent abuse, so you're committing blind. Coverage is thin at the entry tier (ChatGPT and Gemini only; Perplexity and Claude require the $299/mo Growth plan), and it doesn't track AI crawler logs, Reddit or YouTube citations, or generate and publish content for you. If your team has outgrown "here's a chart, now what" and wants a platform that also fixes the problem, or you need broader model coverage without paying enterprise prices, here's what else is worth a look.
Promptwatch
MentionBird's AI Ranking Advice tells you what to do for a given prompt. Promptwatch goes further: it explains why you're invisible using real crawler logs, then has agents that write and publish the fix directly to your CMS. That's the core difference between a prompt tracker and what Promptwatch is built to be, an AI Search Visibility and GEO platform used by 1,840+ brands including Duolingo, Yelp, Typeform, and Fireflies, and rated 4.7/5 on G2.
Where MentionBird stops at a ranked action list, Promptwatch's Agent Analytics show exactly when ChatGPTBot, ClaudeBot, PerplexityBot and 400+ other crawlers hit your site, which pages they read, and where they hit errors, something MentionBird doesn't offer at all. Citation analytics cover Reddit and YouTube specifically, two channels most AI visibility tools (including MentionBird) skip entirely. Content Agents can plan, write, and publish GEO-optimized articles to Webflow, Framer, or WordPress on a schedule, with a review inbox if you want a human in the loop.
Pricing starts at $95/mo (Essential: 1 site, 50 prompts, 6,000 responses, all major LLMs), which lands between MentionBird's Starter ($79/mo, 2 platforms) and Growth ($299/mo, 4 platforms) tiers, but Promptwatch's Essential already covers ChatGPT, Claude, Gemini, Perplexity and more. Professional ($245/mo) adds shopping insights, state/city-level tracking, and automated content generation. There's a 7-day free trial, which MentionBird doesn't offer.
Best for: teams that want the visibility data and the fix in one subscription, rather than a tracker plus a separate content or dev team to act on it.
AthenaHQ
AthenaHQ restructured its pricing in 2026 and now leads with a genuinely free "Essential" tier: $25 in free credit, 300 credits/month, across five models (ChatGPT, Perplexity, AI Overviews, Gemini, Copilot). That's a real advantage over MentionBird, which has zero free access of any kind. Paid Starter runs $295/mo (or roughly $245/mo billed annually) with a $300 monthly credit and 3,600 credits, unlocking six more models including Claude, Grok, DeepSeek, and Meta AI.
AthenaHQ's differentiator is the Athena Citation Engine (ACE), which scores content before you publish it to predict whether it'll get cited, plus Oracle discrepancy detection for catching when AI says something wrong about you. That's a step past MentionBird's reactive "here's what to fix" model into something more predictive, though ACE itself is Enterprise-only, so you won't get it on the free or Starter tiers.
Case studies are strong: Rootly reported roughly 10x citation rate growth, Lago saw a 50% increase in AI-sourced demos, and Grüns claimed a 6x share-of-voice lift in 60 days.
Best for: teams who want to test AI visibility tracking with zero budget before committing, and later want predictive citation scoring if they scale up.
Semrush AI Visibility Toolkit
If you're already paying for Semrush, the AI Visibility Toolkit is a $99/mo per-domain add-on that bolts AI tracking onto your existing keyword and backlink data. It covers ChatGPT, Gemini, AI Mode, Perplexity, and AI Overviews with 25 custom prompts and daily tracking. That's narrower prompt coverage than MentionBird's cheapest plan (100 daily prompt runs) for the same rough price, and Semrush requires an active Semrush subscription underneath it (Pro starts around $140/mo), so the real cost is closer to $240/mo all-in.
Users have been vocal about this being poor value on its own. One reviewer on Rankability's blog put it plainly: "I can't say this tool is worth $99/month... not for a startup and not for a big brand." Following Adobe's $1.9B acquisition of Semrush in August 2026, the standalone free tier disappeared entirely, pushing entry costs even higher for anyone who isn't already deep in the Semrush ecosystem.
Best for: SEO teams who already live inside Semrush for keyword and competitor research and want AI visibility as a bonus metric, not a primary tool.
Otterly.AI
Otterly.AI advertises the lowest sticker price in the category at $29/mo (Lite: 15 prompts, 4 core engines), which undercuts MentionBird's $79/mo Starter significantly. The catch is that "4 core engines" means ChatGPT, AI Overviews, Perplexity, and Copilot, while Gemini, Google AI Mode, and Claude all cost extra add-ons layered on top ($9-$149/mo depending on plan and engine). Get all seven engines on Lite and you're actually paying around $76/mo, close to MentionBird's price for less prompt volume.
What Otterly does better: unlimited team members on every plan, including the $29 tier, versus MentionBird's 10-seat cap on Starter. Otterly also includes GEO Audits and API/MCP access starting at the Standard tier ($189/mo), and has real recognition (Gartner Cool Vendor 2025, G2 High Performer 2026 for AEO).
What it lacks compared to MentionBird: MentionBird's AI Ranking Advice reads the actual cited sources for a losing prompt and returns an effort/impact-scored action plan on every plan tier. Otterly's recommendations are more generic GEO audit output, not a per-prompt action plan tied to specific competing sources.
Best for: solo founders and small teams who want the lowest possible entry price and don't need every AI engine covered from day one.
Profound
Profound built its reputation on depth: citation analysis, sentiment, competitive presence, and now FactCheck (which monitors and auto-corrects inaccurate AI answers about your brand via integration with Noble's Mention Refresh) and Citation Decay (tracking week-over-week visibility decline). It was named a Representative Vendor in Gartner's inaugural 2026 Market Guide for Answer Engine Visibility Tools, which counts for something if you need to justify the spend internally.
The catch is coverage-to-price ratio at the entry tier. Starter is $99/mo billed annually but tracks ChatGPT only, with 50 prompts, one seat, and no data export. That's worse coverage than MentionBird's $79/mo Starter (which covers ChatGPT and Gemini). You need Growth at $399/mo to get three engines (adding Perplexity and Google AI Overviews), and the full nine-engine spread, including Gemini, Claude, Copilot, Grok, and DeepSeek, is Enterprise-only behind a custom quote, with third-party estimates putting real-world Enterprise deployments at $2,000-$5,000+/mo.
Best for: enterprise teams with budget for the Enterprise tier who need FactCheck-style automated remediation and don't mind a demo-gated sales process.
Scrunch AI
Scrunch AI's whole angle is agent traffic attribution, actually seeing which AI bots crawled your site and correlating that with citations, plus persona and language modeling and funnel-stage analysis. That's genuinely different from MentionBird's prompt-and-source focus, and it's a feature most competitors in this list don't offer at all outside Promptwatch's crawler logs.
Pricing consolidated in 2026 into a single Core plan at $250/mo (125 prompts, 4 LLMs: ChatGPT, Perplexity, Google AIO, Copilot, 5 site audits/mo, 5 seats), with a 7-day free trial. That's over three times MentionBird's entry price for fewer prompts (125 vs. MentionBird's 100 daily runs), though Scrunch's per-seat allowance and audit tooling are more built out. Claude, Gemini, Meta AI, AI Mode, and Grok are all Enterprise-only, same limitation Profound has.
Best for: mid-market and enterprise brand or reputation teams that specifically want to correlate AI bot crawl activity with citation outcomes.
Brand24
Brand24 is worth mentioning mainly as a category caveat: it's a social listening platform first (25M+ sources across social, news, forums, podcasts, reviews) with AI visibility bolted on as a paid add-on across every tier, from Individual ($199/mo annual) up through Enterprise ($1,499/mo). The AI add-on price isn't publicly listed, which is itself a signal it's not the core product.
If you need broad brand mention monitoring across social platforms and occasionally want to check AI citations too, Brand24 covers both in one subscription. But if AI search visibility is your primary goal, you're paying for a lot of social listening infrastructure you may not need, and the AI feature itself is clearly secondary to Brand24's actual specialty.
Best for: teams that already need broad social listening and want AI visibility as a bolted-on extra, not a primary use case.
Which one should you pick?
If you just want the cheapest possible entry point to start tracking, Otterly.AI's $29/mo Lite plan or AthenaHQ's free tier beat MentionBird on price, though both have coverage gaps you'll hit quickly. If you're already inside the Semrush or Ahrefs ecosystem, the AI add-ons make sense as a bonus metric rather than a standalone purchase. If you need enterprise-grade depth and don't mind demo calls and custom pricing, Profound or Scrunch AI's Enterprise tiers deliver agent attribution and predictive scoring that smaller tools don't.
But for most teams choosing between "a tracker that tells me what's wrong" and "a platform that also does something about it," Promptwatch is the strongest overall alternative to MentionBird. It matches or beats MentionBird's per-prompt action-plan idea with Unified Actions and Content Agents, adds crawler-log visibility that explains the why behind your scores, and covers Reddit and YouTube citations that MentionBird's own comparison pages don't mention tracking at all.
