What is Otterly.AI?
Otterly.AI describes itself as "an innovative AI Search monitoring and optimization platform". It tracks prompts daily on ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Microsoft Copilot, Perplexity and Claude, and reports brand mentions, average position, share of AI voice ("the percentage of citations you own versus competitors"), sentiment and the links being referenced. It adds brand reports, a GEO content audit, AI prompt research, ChatGPT ads tracking, agent analytics, a Looker Studio connector and an API, and says it is used by more than 30,000 marketing professionals.
What is Tonecast?
Tonecast is a SaaS platform that shows what AI assistants (ChatGPT, Claude, Gemini and Perplexity) say about a brand, product, person or topic, and which web pages shaped those answers. Tonecast (tonecast.io) samples the engines every week through their official APIs, reports every rate with a 95% confidence interval, builds a source graph of the pages behind the answers in three tiers (Cited, Formative, Owned), checks the factual claims in the answers against your fact sheet, and tests whether the sources move before the answers do (Early signals). It is not to be confused with other products that share the name.
How do prices compare?
Otterly.AI's pricing page shows euro prices when visited from Italy (its FAQ says prices are in US dollars or euros), excluding tax, with 15% off on annual billing. Tonecast lists euro prices for companies in Europe and dollar prices for the rest of the world; yearly billing is 20% less.
Otterly.AI plans, 10 November 2026
| Plan | Price | Prompts | AI engines | Notes |
|---|---|---|---|---|
| Lite | €29 / month | 2,000 credits a month (about 20 prompts daily on 3 engines) | 3 of 7: ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot, Google AI Mode, Gemini, Claude | 1 workspace, 3 recommendations a week, daily tracking; unlimited team members, countries and languages; no extra credit packs |
| Standard | €189 / month | 15,000 credits (about 160 prompts daily on 3 engines) | 3 of 7, same choice | unlimited workspaces, Data Studio connector, 2,000 API and 2,000 MCP requests a month; 5,000 more credits for €65 a month |
| Premium | €489 / month | 50,000 credits (about 535 prompts daily on 3 engines) | 3 of 7, same choice | daily or weekly tracking, 5,000 API and MCP requests, personal onboarding; 10,000 more credits for €99 a month |
| Enterprise | custom | from 1,000 prompts | unlimited | SSO, custom payment terms, dedicated customer success manager, quarterly GEO health check |
A credit is one prompt checked once on one engine, so a prompt tracked daily on one engine uses 31 credits a month; a Claude answer counts as three credits. Every plan can track every engine, and the number of prompts depends on how many engines you choose. The FAQ states a free trial for new users.

Like for like
At the entry level the two are close in price and far apart in shape. Otterly.AI Lite (€29) has 2,000 credits a month, about 20 prompts tracked daily on three engines; with Claude among them fewer prompts fit, because each Claude answer counts as three credits. Tonecast Essential ($34, or €29 in Europe) tracks 20 prompts per language on ChatGPT, Claude and Perplexity, sampled weekly with six runs per prompt and engine a month, and includes the source graph, claim check and the Early signals view; Gemini needs the Pro plan. Daily numbers favour Otterly.AI; intervals, formative sources and claim checking favour Tonecast.
Which AI engines does each cover?
Otterly.AI's plans can track any of ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot, Google AI Mode, Gemini and Claude, paid in credits; the self-serve plans are sized on three of them, and a Claude answer counts as three credits. Tonecast covers ChatGPT, Claude and Perplexity on every plan and Gemini on Pro and Agency, always through the engines' official APIs with web search or grounding enabled; Google AI Overviews is on the way, and AI Mode and Copilot are not covered.
What does each one measure?

Questions people ask
Which is cheaper, Tonecast or Otterly.AI?
The entry plans are close: Otterly.AI Lite costs €29 a month for 2,000 credits, about 20 prompts tracked daily on three engines; Tonecast Essential costs $34 (€29 in Europe) for 20 prompts per language on ChatGPT, Claude and Perplexity. On Otterly.AI a Claude answer counts as three credits; on Tonecast Claude is one of the three engines on every plan.
Does Otterly.AI check whether AI answers are correct?
Its pages describe mentions, position, share of AI voice, sentiment and referenced links, not a check of factual claims. Tonecast's claim check classifies each claim as consistent, incorrect, outdated or unverifiable against your fact sheet.
Why does Tonecast sample weekly when Otterly.AI tracks daily?
Tonecast repeats each prompt several times a month on each engine and reports every rate with a 95% confidence interval, so a change can be told from noise. Daily single runs show movement sooner but without an interval.
