Key takeaways
- Check which engines are included on your plan. Several tools sell Claude, Gemini or AI Mode as add-ons.
- Prompt allowance drives price more than features. Count the prompts you need before comparing plans.
- If you use AI agents or dashboards, check for an API or MCP server.
1. Which engines do your buyers use?
Every tool tracks ChatGPT. Coverage beyond that varies a lot, and some engines are paid add-ons. Otterly.AI, for example, sells Claude, Gemini and AI Mode as add-ons, while Scrunch AI includes Claude and Meta AI on its entry plan. Check the engines on the plan you'd actually buy.
2. How many prompts do you need?
Prompt allowance is usually what you pay for. A small business can learn a lot from 15 to 50 prompts; agencies and large brands track hundreds.
| Tool | Entry plan | Prompts |
|---|---|---|
| Otterly.AI | $29/month | 15 |
| Semrush AI Visibility | $99/month per domain (annual) | 25 |
| Similarweb AI Brand Visibility | $99/month | 150 |
| Scrunch AI | $250/month (annual) | 350 |
3. Do you need market research or tracking?
Most tools track prompts you choose. Ahrefs Brand Radar also lets you explore an index of 449M+ prompts a month, which helps when you don't yet know what people ask. Semrush vs Ahrefs compares the two suite options.
4. How will you use the data?
If results feed dashboards, client reports or AI agents, look for an API or MCP server. Otterly.AI, Knowatoa, Promptwatch and Goodie all state API or MCP access on some plans; check which plan includes it.
Tip
An MCP server lets an AI agent read your visibility data directly, so it can suggest content fixes based on what the engines actually said.
5. Do you want tracking only, or tracking plus content?
Some tools stop at measurement. Others, like Gauge and Writesonic, also produce the content meant to improve your visibility. That's convenient, but compare the price with a tracker plus your existing content process.
