Otterly.AI is a lightweight, affordable way to start tracking ChatGPT, Google AI Overviews and Perplexity mentions. The three things buyers check before they outgrow it are Claude coverage (an add-on, not included), a per-answer evidence log, and how it stacks up against five other tools on price.
The two things that send an Otterly.AI buyer looking elsewhere are Claude coverage and evidence depth. Otterly's Lite plan covers ChatGPT, Google AI Overviews, Perplexity and Copilot by default, and Claude is a paid add-on rather than part of the base plan, so a company whose buyers lean on Claude pays extra to see it at all. The other gap is depth: Otterly reports a mention count and shows the sources cited alongside it, which is more than a bare score, but it stops short of a full per-answer log you can hand to a writer and say "fix this sentence."
Bottom line: if Claude answers matter for your buyers by default, or you want to open the exact sentence that cost you a mention, these are the two questions to ask before you pay.
Our full ranking, the 10 best AI visibility tools in 2026, covers ten vendors in depth. Here is how the tools an Otterly.AI buyer compares most often stack up side by side:
| Tool | Engines measured | How answers are shown | Free tier | Starting price | Who it fits |
|---|---|---|---|---|---|
| Otterly.AI | ChatGPT, Google AI Overviews, Perplexity, Copilot on Lite; Claude/Gemini paid add-ons | Mentions + cited sources | Free trial only | see vendor pricing page | Solo marketers, smallest budget |
| Peec AI | 3 of 6 models per plan, from a pool of ChatGPT, Google AI Mode, AI Overviews, Copilot and Gemini; Claude not listed | Visibility % + cited sources per prompt | Free trial only | see vendor pricing page | Teams that want to build a large, custom prompt set |
| Profound | ChatGPT, Gemini and Google AI Overviews on the trial; Claude and others on higher tiers | Composite scores; agent-run credits | No ongoing free plan (one-time trial) | see vendor pricing page | Enterprise teams wanting agent-level analytics |
| Semrush AI Toolkit | ChatGPT, Google AI, Gemini, Perplexity, no Claude | Share of voice + sentiment | No standalone free tier | see vendor pricing page | SEO teams already paying for Semrush |
| Ahrefs Brand Radar | Sold per engine index, up to 6 | Mentions / share of voice | No (comes with free Ahrefs account) | see vendor pricing page | Teams that want AI share of voice next to Ahrefs SEO data |
| Reflexa | ChatGPT, Claude, Perplexity | Raw AI answer + sources attached to every finding | Yes, first check free, no card, ~3 min | $49/mo | Teams that want a measurement they can defend, not a black-box score |
Proof: engine and evidence details above reflect each vendor's own published tier information as surveyed in our wider 10 best AI visibility tools ranking, September 2026. This run could not reach the vendors' own pricing pages (network blocked), so prices are left to the vendor's own page rather than guessed or copied from a review site. Reflexa's price is published on our own pricing page.
Note: engines listed are each vendor's own published tier limits, not a claim about what they technically can query; a higher tier usually unlocks more.
Otterly.AI and Peec AI sit closest together of any two tools in this comparison, tied at 49 of 300 named answers in our own check. Otterly leans toward the simplest setup and the lowest price, with a mention count and cited sources per prompt out of the box. Peec AI leans toward a large, fully custom prompt set that a team writes and owns, at a higher entry point. Neither includes Claude by default.
Pick by workflow: Otterly.AI for the smallest budget and the simplest setup; Peec AI for a team that wants to hand-write and own a large prompt set.
Reflexa is the one in this comparison that attaches the complete AI answer and its sources to every finding, per engine. Otterly.AI and Peec AI go a step further than a bare percentage by showing which sources an engine cited for a given prompt, which is useful, but both stop at the source list rather than a full answer-by-answer log the way Reflexa's public AI Visibility Index does. Profound, Semrush AI Toolkit and Ahrefs Brand Radar each report a score, a percentage or a share-of-voice figure as the primary output.
Why it matters: you cannot fix an answer you cannot read. A count tells you that you are losing; the raw answer tells you which sentence, which competitor and which source cost you the mention.
We asked ChatGPT, Claude and Perplexity 100 real buyer questions about AI visibility tools in September 2026 and counted the names in all 300 answers. This is the same kind of measurement these tools sell, run on their own category:
| Tool | Answers naming it (of 300) |
|---|---|
| Profound | 94 |
| Semrush | 67 |
| Otterly.AI | 49 |
| Peec AI | 49 |
| Ahrefs | 39 |
| SE Ranking | 21 |
| Scrunch AI | 19 |
Proof: Reflexa AI Visibility Index, September 2026 (100 buyer questions about AI visibility tools, 3 engines, 300 observed answers, counted by name).
Read it as rank, not market share: 49 of 300 is roughly one in six answers, tied with Peec AI for third place, behind Profound and Semrush, not a crowd favorite.
You can shortlist an Otterly.AI alternative without buying anything yet:
Reflexa, Peec AI, Profound, Semrush AI Toolkit and Ahrefs Brand Radar are the tools buyers compare Otterly.AI against most often. Which one fits depends on whether Claude needs to be included by default, whether you want a full per-answer evidence log, and your budget.
Otterly.AI suits the smallest budgets and a simple mention count; Peec AI suits a team that wants to hand-write a large, fully custom prompt set. Neither publishes a full per-answer evidence log, and in our own September 2026 check both were named in 49 of 300 answers, tied for third place.
Otterly.AI's Lite plan covers ChatGPT, Google AI Overviews, Perplexity and Copilot; Claude and Gemini are paid add-ons rather than included by default. Confirm the current add-on list and price on Otterly's own pricing page before you commit a budget to it.
Reflexa attaches the full raw AI answer and its sources to every finding, for ChatGPT, Claude and Perplexity. Otterly.AI shows which sources an engine cited alongside a mention count, which is useful, but it does not publish a complete answer-by-answer evidence log the way Reflexa does.
Reflexa's first check is free, no card required, and takes minutes, with Claude included from the start. Confirm Otterly.AI's and Peec AI's current entry prices on their own pricing pages, since self-serve tiers in this category change often.
The free check reads your pages the way ChatGPT, Claude and Perplexity read them — 23 structural checks, evidence attached, no card needed.
