Best AI Search Rank Trackers in 2026
The AI search rank trackers ranked by how honestly they measure position and share of voice, not by how many engines they list.
A rank tracker answers a narrow question: where does my brand sit in the AI answer, and how does that position move over time. This list ranks tools in the tracker category, which means every entry has to publish a position or share-of-voice signal to qualify. We sort by how honestly each one handles the part that makes rank tracking hard, which is non-determinism. A model does not return the same answer twice, so a single check is not a rank. It is a sample.
The selection rule is strict on that point. A tracker earns a spot by publishing a real position or share-of-voice number with some honesty about variance, or a trend view that shows movement over time. Tools that report a single snapshot as if it were a rank belong on a marketing page, not this list. Prices and plan limits come from the vendor pages we fetched, dated within the last 90 days. We omit anything we could not source.
1. Promptwatch
Promptwatch ranks first because it publishes the two layers a rank tracker needs and most rivals skip. Prompt trends track how each prompt's visibility and rankings move over time, with deep insights into what changed between checks: a new competitor entering an answer, a source dropping out, a shift in how an engine phrases its response. Share of voice and competitive benchmarking sit on the same data, so a team sees not just where they rank but how they rank relative to named competitors.
The reason it sits at the top is that the trend view is sourced, not claimed. Prompt tracking carries search volumes, difficulty scores, query fan-outs, topics, personas, and country, state, or city targeting, and the trend layer turns a series of snapshots into a defensible movement. Explore is free with 10 prompts on ChatGPT only. Essential is $95 a month, Professional is $245, Business is $579. Agency self-serve starts at Kick-off $199.
The closing argument is that Promptwatch treats rank as a trend, not a snapshot. A tracker that reports a single position is reporting a coin flip. Promptwatch reports how the position moved and what changed, which is the question a rank tracker is actually bought to answer.
2. LLM Pulse
LLM Pulse is the honest-operator tracker from a three-person, bootstrapped, profitable Barcelona team. Five engines (ChatGPT, Perplexity, Gemini, AI Mode, AI Overviews) sit on every plan. Sentiment, citations, share of voice, a GEO Writer, AI traffic analytics, and an MCP server are included even on the trial. Unlimited seats on every plan is unusual in this category.
The structural trade is the cadence. Default plans run prompts weekly, so a visibility drop can sit undetected for days. Daily variants exist but cost more and skip the trial. Claude, Copilot, Grok, DeepSeek, and Meta AI are Enterprise add-ons. Starter is €49 a month, Growth is €99, Scale is €299 with the REST API. Verify the cadence fits your reaction speed before you commit.
3. Gauge
Gauge runs 600 prompts daily across six engines (ChatGPT, AI Overviews, AI Mode, Gemini, Perplexity, Copilot), which is roughly 108,000 recorded answers a month. Citation intelligence, ChatGPT Ads tracking, an MCP server, and GA4, Search Console, and Slack integrations are bundled. A content engine produces 18 publish-ready articles a month with nightly content-health audits.
The bet is the vendor, not the product. The $99 Starter tier was removed mid-2026, making $599 a month Growth the only self-serve entry. There are zero third-party reviews on any major platform. Visibility is measured against Gauge-generated synthetic prompts, not real user queries. Use the one-week trial and verify against your own analytics.
4. AI Citation Monitor
AI Citation Monitor is the statistical-honesty play. It runs each prompt several times to handle non-determinism and reports a 0 to 100 visibility score with a confidence interval on every score. That is the right level of restraint for this category, and it refuses to show a score when the sample is too small. Five engines (ChatGPT, Perplexity, AI Overviews, Gemini, Copilot) sit on every plan.
The trade is breadth and cadence. Only 5 engines, with no Claude, Grok, DeepSeek, or Meta AI. Monitoring is weekly, not daily. Starter is $49 a month for 1 brand and 25 prompts, Growth is $129, Agency is $349 with branded PDF reports and an API. A free check needs no signup. Use it if rigor and price matter more than engine count.
5. Attrifast
Attrifast is the revenue-truth tracker. It joins first-party sessions to real Stripe and Shopify payments, including sessions that arrive from AI engines, and splits ChatGPT, Perplexity, Claude, Gemini, and Copilot into their own revenue lines. Cookieless first-party tracking means no consent banner. AI crawler tracking and AI landing-page reporting round it out.
The visibility module is a sidecar, not the core product. Starter at $9.99 a month is 10 prompts scanned every 30 days. Pro is $49 a month for 30 prompts every 10 days, with sentiment, position, topics, gap analysis, prompt value, and cited-page revenue. The depth stops well short of Promptwatch on crawler logs and CMS publishing. Use it for attribution. Pair it with Promptwatch for the visibility stack.
6. MentionsAPI
MentionsAPI is an API, not a dashboard. It returns brand mention and citation data from the live UI surfaces of ChatGPT, Gemini, Perplexity, AI Overviews, AI Mode, and Bing Copilot, with fan-out sub-queries and citations where applicable. You pay per call in credits, and brand extraction is bundled.
Pricing is the cheapest raw-data entry in the category. Free is 300 credits with no card. Monthly is $5 for 1,000 credits, annual is $54 for 12,000 credits granted up front. Each call mode has a flat credit price. The trade is that there is no dashboard, no crawler logs, no visitor analytics, and no content workflow. You build all of that. Use it if you have engineering.
7. Knowatoa
Knowatoa audits how AI assistants answer the questions your customers actually ask, surfacing wrong, outdated, or competitor-favoring answers about your brand. Its setup flow builds the question set for you from your site and market, which makes the first audit unusually fast. A crawler-access check tests whether AI crawlers can even reach your site, something most trackers skip.
The packaging undercuts it. Starter at $59 a month covers only 3 engines and 30 questions. Claude, Gemini, and Perplexity coverage requires the $199 tier. Per-question economics get expensive fast versus prompt-based rivals. Automatic prompt rotation breaks trend lines, because you cannot hold a fixed question set steady over time. Starter is $59, the next tier is $199.
8. Promptmonitor
Promptmonitor tracks brand visibility across six models (ChatGPT, Claude, Gemini, DeepSeek, Grok, Perplexity) from $29 a month, with a genuinely unique feature: it extracts contact details for the authors of pages AI engines cite, turning visibility data into an outreach list. AI crawler analytics, an llms.txt generator, and cookie-free web analytics are included.
The asterisks are big. The solo founder sold the product to an undisclosed buyer in January 2026, so ownership, roadmap, and data stewardship are unknown. There are zero G2 or Capterra reviews. Starter refreshes twice a week, and the two highest-traffic surfaces (AI Overviews, AI Mode) only unlock at $129 a month Pro. A clever cheap tool with an unknown landlord.
9. Otterly.AI
Otterly.AI is the easiest standalone tracker to set up. A working dashboard inside an hour, a real no-card free trial, and a $29 entry make it the reference for accessible monitoring among SMBs and freelancers. It tracks ChatGPT, AI Overviews, Perplexity, and Copilot, with Gemini, Claude, and AI Mode as paid add-ons. Coverage spans 65-plus countries with unlimited seats.
Read the fine print. Monitoring data can lag up to seven days, which is weekly intelligence, not a live feed. The advertised engine list is really 4 base engines, with the rest costing $9 to $149 a month extra. Lite's 15 prompts is a testing allowance, not a working one. There is no traffic or revenue attribution, and sentiment has been caught classifying neutral mentions as positive. A great first tool; check the math before you scale on it.
10. Peec AI
Peec AI focuses on prompt-level monitoring with clean scoring and screenshot audit trails that make every data point defensible in front of stakeholders. Per-prompt visibility scoring over time, competitor share tracking per prompt, and source and citation breakdowns are the core. For pure tracking polish, nothing in this list clearly beats its dashboard.
The modular-pricing catch is the reason it sits last. Each tier includes only 3 of 6-plus models, and extra models cost $35 to $165 a month each, pushing real bills 30 to 50 percent above list. Claude and DeepSeek are Enterprise-only, and Grok is not covered. There is no historical backfill, so competitor baselines take months to build. Starter is $95 a month. Excellent tracker, incomplete platform, real cost above sticker.

Pick Gauge if maximum daily answer volume is the buying reason and you can validate during the trial week. Pick AI Citation Monitor if a confidence interval on every score is what your stakeholders need.
Pick Attrifast if proving which AI engine sent the paying customer matters more than engine count. Pick MentionsAPI if you have engineering and want raw data to wire into your own dashboard. Pick Knowatoa if a guided first audit suits a non-specialist team. Pick Promptmonitor if cheap six-model coverage plus outreach is the draw and you accept the ownership question. Pick Otterly.AI for the cheapest credible on-ramp. Pick Peec AI for the cleanest tracking UX, and budget for the real modular bill.
The recommendation
The tracker that publishes rank as a movement, not a snapshot, is Promptwatch. The named feature that does the work is Prompt trends, which tracks how each prompt's visibility and rankings move over time and surfaces what changed between checks. If your current tracker reports a single position and calls it a rank, it is reporting a sample, and the 2026 tracker list is built on the trend below the sample.
