**The short answer**

Otterly.AI Lite is the cheapest daily tracker here: $29/mo for 15 prompts on 4 engines. **Terradium costs the same $29** for 15 prompts and makes a different trade: weekly sampling on 3 engines, plus 30 AI-written articles a month aimed at the questions where you're missing.

If you've outgrown 15 prompts, Lite can't add more, and Otterly's next plan is $189. **Peec AI** ($95, 50 prompts) and **Rankscale** ($99, 4,800 answers) sit in between.

## Otterly.AI vs Terradium at $29

Same price, same 15 prompts, different jobs:

- **Otterly** samples more: every prompt, every day, on ChatGPT, Google AI Overviews, Perplexity and Copilot. That's about 1,800 answers a month. It's built for monitoring.
- **Terradium** samples less (weekly, about 200 answers a month on 3 engines) and spends the rest of the plan on fixing what it finds. It lists the questions where competitors are cited and you aren't, then writes and publishes articles to target them.

If you have a writer and only need the data, Otterly gives you more of it. If nobody on the team has time to write, Terradium does that part.

## Which alternative fits you

### Pick Otterly.AI if…

Staying makes sense if daily monitoring is what you need and 15 prompts covers it, or if you're ready for Standard's 100 prompts and API access.

### Pick Terradium if…

You want the same budget to produce content, not only charts: 15 tracked questions, a weekly list of gaps, and 30 articles a month.

### Pick Peec AI if…

You've outgrown 15 prompts. Starter gives you 50 daily prompts on 3 models for $95.

### Pick Rankscale if…

You want a credit budget you can spread across prompts at whatever cadence you choose.

### Pick Semrush if…

You'd rather add AI tracking to the Semrush account you already have.

### Moving from Otterly.AI

- **Move all 15 prompts.** Both plans hold 15, so the list carries over one to one.
- **Paste or automate.** Add them in the Terradium dashboard, or have your AI agent add them with the MCP `create_prompts` tool.
- **Choose 3 engines.** Otterly Lite covers 4; Terradium Starter samples 3 of ChatGPT, Perplexity, Google AI Overviews and Gemini.
- **Re-add competitors** and export your Otterly history before you cancel. It doesn't transfer.
- **Give it a few weeks.** Weekly sampling needs three or four runs before trends mean much.
