Nightwatch alternative for AI visibility: the same 50 prompts for less.
Nightwatch combines keyword rank tracking with AI prompt tracking on six engines. If you only want to see how AI assistants talk about your brand, Aiso tracks the same 50 prompts for less. If you also need keyword rank tracking, Nightwatch is the better single purchase.
Bottom line
Nightwatch Starter lists 50 AI prompts and 500 tracked keywords for €79 a month on yearly billing, about €1.58 per tracked prompt. Aiso Starter tracks 50 prompts for $16 a month billed yearly, about $0.32 per prompt. The two prices are in different currencies and Aiso has not converted them. Nightwatch also tracks 6 engines and 500 keywords on the same plan, and Aiso does not track keywords.
Confidence: Aiso calculation from vendor pricing pages read on 20 October 2026. It is not a product test or an independent audit. Prices change and vary by region.
How the price per prompt is calculated
- Nightwatch pricing page, read 20 October 2026: Starter €79 a month, shown with €948 billed yearly, 500 keywords, 50 AI prompts and 1,500 AI answers a month. Professional €159 a month with 2,500 keywords and 150 prompts. Agency €399 a month with 7,500 keywords and 500 prompts. All plans list ChatGPT, Claude, Gemini, Perplexity, AI Mode and AI Overview, with a 14 day free trial.
- Aiso Starter: $16 a month billed yearly ($19 billed monthly), 50 tracked prompts, 3 AI models, daily tracking. Source: Aiso pricing data, read 20 October 2026.
Nightwatch Starter: €79 ÷ 50 = €1.58. Aiso Starter: $16 ÷ 50 = $0.32. Nightwatch Professional: €159 ÷ 150 = €1.06.
Limits: This is an Aiso calculation from published prices, not a test. Euros and dollars are not converted, so read the two figures as separate price points rather than a ratio. Nightwatch lists the yearly rate as its monthly price and does not state a separate monthly-billing price. The Nightwatch plan also includes keyword rank tracking that Aiso does not offer, and its prompts run on 6 engines against 3 on Aiso Starter.
Choose Nightwatch if
- You also need keyword rank tracking next to AI prompt tracking.
- You want Claude, AI Mode and AI Overview tracked from the first plan.
- You want a larger prompt tier, up to 500 prompts on Agency, with unlimited seats.
Choose Aiso if
- You mainly want to know what people ask AI assistants and whether your brand appears in the answers.
- You want prompts based on real, consent-based ChatGPT conversations.
- You want a lower entry price for AI visibility alone, with unlimited users.
