Cheapest tool that tracks AI answers daily rather than weekly

Cheapest ready-made daily tracker I found: BrandAxis Lite at $19/month, for 20 prompts checked daily across three AI models, including ChatGPT. (geotoolindex.com)

If you’re comfortable setting up a more DIY option, Apify’s tracker charges per answer instead of a monthly subscription: $0.15 per check, plus model usage (typically about $0.001–$0.01 per answer). It can be scheduled daily, but it’s less of a plug-and-play dashboard. (apify.com)

Bottom line: BrandAxis for the cheapest simple subscription; Apify if you only need a small number of prompts and don’t mind some setup. Daily AI answers can vary from run to run, so treat them as snapshots rather than a fixed ranking. (searchable.com)

The cheapest tools that refresh daily start at about $29/month, but the sources disagree on the details, so check the vendor's pricing page before you pay.

Top picks

• Otterly.AI Lite, $29/month. This is the most cited option. The Lite plan includes daily tracking of 15 prompts and tracks Google AI Overviews, ChatGPT, Perplexity, and Microsoft Copilot. Claude, Google AI Mode, and Gemini cost extra. One source lists the annual price at $25 annual.
• Wellows Basic, $29/month. This is the main alternative. One roundup says its tracking is Daily (every plan) and covers All five — ChatGPT, AI Overviews, AI Mode, Gemini, Perplexity. The same roundup gives its trial as a 7-day free trial.

Cheaper, but check daily coverage first

• Rankscale, from $20/month. It has the lowest headline price, but one review says Not for: Heavy daily tracking on the base tier. Its entry plan's limits are also Limits not published.

Next tier up, if 15 prompts is too few

• Peec AI, $95/month. Its Starter plan is $95/month for 50 prompts and 3 AI models, and one roundup describes it as Best for daily tracking on a budget.
• Nightwatch, from $32/month. It is a broader SEO tool. Its LLM tracking is not clearly daily at the entry price, and one source lists its daily-refresh plan at $39/mo.

Recommendation: Start with Otterly Lite if you track fewer than about 15 prompts on ChatGPT, Perplexity, and Google AI Overviews. Choose Wellows Basic if you need Gemini or AI Mode at the same price. Before paying, confirm on the vendor's site that the plan refreshes every day and see how many prompts it allows. Vendors change prices often, and these figures come from third-party roundups dated within the last few weeks.

For tracking AI answers—specifically monitoring how your brand is mentioned, cited, or ranked in AI-generated responses (like ChatGPT, Google AI Overviews, or Perplexity)—the "cheapest" option often depends on your specific needs (e.g., whether you need a simple monitoring tool or a full SEO suite).

Based on current 2026 market data, here are the most cost-effective tools that provide daily tracking.

Top Recommendations for Daily AI Answer Tracking

Key Insights for Your Search

• "Daily" Definitions Vary: Be aware that "daily tracking" can mean different things across platforms. Some run one scan per day at a specific time, while others use a credit system that allows you to distribute your daily checks across different engines. Always confirm whether the plan you choose includes the specific AI engines (e.g., Gemini vs. ChatGPT) you care about, as some cheaper tiers limit the number of platforms.
• Avoid "Over-Buying": If you already pay for a major SEO suite like Semrush or SE Ranking, check your existing plan. They have introduced "AI Visibility" toolkits that may already be included or available as an affordable add-on, which is often more cost-effective than adding a new subscription.
• Monitoring vs. Observability:
  • If you are a marketer looking to see how your brand appears in AI search results (AEO), use tools like Otterly.AI or Arvow.
  • If you are a developer looking to monitor the performance, cost, and quality of your own AI application/agent, look at observability tools like Langfuse or Helicone, which often have generous free tiers for low-volume daily monitoring.

Summary of Best Value

• Lowest Price: Otterly.AI is widely recognized as the lowest entry price for daily monitoring of the four major AI engines.
• Most Comprehensive Budget Option: Arvow is a strong contender because it bundles multiple AI platforms into one flat rate, avoiding the common "pay-per-engine" trap that makes other tools more expensive as you scale.

Recommendation: If you are just starting out, Otterly.AI or ZipTie are excellent starting points. Use their trials to confirm they track the specific prompts and engines that are most relevant to your business before committing to a monthly subscription.

Otterly.ai Lite appears to be the cheapest option, at $29/month for 15 prompts tracked daily across ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot.¹²

If you’re willing to pay annually, one comparison lists it at $25/month.³ Check Otterly’s current pricing page before signing up, since plan prices and prompt limits can change.
