Use Case Recommendations
Best for: Otterly.AI
Otterly.AI monitors whether AI search engines mention your brand and cite your site, across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Gemini and Claude. The product is organised in three stages. Prompt research surfaces the prompts, topics and intent patterns that actually drive AI-generated answers in your category, so you are tracking real questions rather than guessing at them. Analytics then measures how your brand appears — or disappears — against competitors, with brand coverage over time, raw mention counts, average brand position and a brand visibility index, sliceable by branded versus non-branded, top versus bottom of funnel, engine and country across fifty-plus markets. Optimisation closes the loop with a generative-engine-optimisation audit, link-citation analysis, domain ranking and weekly recommendations. For teams building this into a workflow rather than a dashboard habit, the middle tier and above expose an API, an MCP server and agent analytics — the MCP surface in particular means the data is reachable from an agent rather than only from a browser. Agencies get unlimited workspaces and unlimited team members on every tier, which is unusual in a category that normally charges per seat. The vendor reports 30,000-plus marketing users and holds a Cool Vendor listing in an AI-in-marketing report.
Ideal use cases:
- •Teams or individuals who need tracking across chatgpt, ai overviews, ai mode, perplexity, copilot, gemini and claude
- •Teams or individuals who need prompt research surfacing the questions that drive answers in your category
- •Teams or individuals who need brand visibility index, average position and competitor comparison
- •Teams or individuals who need link citation analysis and generative-engine-optimisation audits
- •Anyone focused on geo workflows
- •Anyone focused on ai-search workflows
Best for: Sonar
Sonar is an app-store optimization tool built specifically for indie app developers, and it argues its case against the incumbent ASO platforms on two axes: price and data provenance. The pitch on provenance is that keyword search volume comes directly from Apple Search Ads and Google Play autocomplete rather than from a modelled estimate, so the numbers a developer optimizes against are the ones the stores themselves report. Every keyword also carries a difficulty score from 0 to 100 derived from competitive analysis of the current top-ten ranking apps, which is the number that tells a solo developer whether a term is worth chasing at all. Once an app is added, Sonar tracks its position on every keyword daily across both stores and all countries, keeps unlimited rank history for as long as the subscription runs, and runs a keyword gap analysis that surfaces terms competitors rank for and you do not. Alerts fire on competitor metadata moves and on ranking drops. A revenue-estimates feature projects monthly revenue, installs, retention and in-app-purchase pricing for any app on the store. For automation there is a REST API, a CLI and an MCP server, so agents like Claude and Cursor can run ASO research against live store data instead of guessing.
Ideal use cases:
- •Teams or individuals who need keyword volume pulled from apple search ads and google play autocomplete, not estimates
- •Teams or individuals who need 0–100 keyword difficulty scored against the current top-ten ranking apps
- •Teams or individuals who need daily rank tracking on both stores, all countries, with unlimited history
- •Teams or individuals who need keyword gap analysis against uncapped competitors
- •Anyone focused on aso workflows
- •Anyone focused on app-store workflows
