Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
1.8
GPA, above 13 of the 157 other AI search visibility tools we grade
Erlin tracks how often a brand is named in ChatGPT, Perplexity, Gemini and Claude answers, which competitors appear instead and which sources the answers cite, then ranks fixes by effort and impact. Higher plans write and optimize content in the brand's voice. A lead qualification add-on, in beta, adds a website chatbot, follow-up by email and Telegram, and a CRM view of where leads came from.
To get you started, here are 8 things to know about Erlin, taken from its own pages and our grades.
Prompts are suggested for you, but there's a Brand Memory to fill in and Analytics and Search Console to connect.

The report card
Best for AI tracking with article writing on higher plans
Erlin tracks how often ChatGPT and Perplexity name you, which rivals show up instead and which sources the answers cite, then ranks the fixes by effort. Starter is $47 a month but billed only yearly, at $564, with no writing. Gemini and content need Standard at $197, Claude and the API need Pro at $397, the trial costs $7, and Google AI Overviews isn't tracked.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Starter is $47 a month, billed yearly as $564, in the middle stretch of this category. It has only ChatGPT and Perplexity and no writing; Standard, with Gemini and content, is $197. |
| Free plan and trial | F | Nothing is free. Each plan opens with a 7-day trial that costs $7, and after that it's billed by the year. |
| Features | C | Prompt discovery, mentions and share of voice, cited sources, fixes ranked by effort, writing in your brand voice and AI traffic from GA4. But its engines stop at ChatGPT, Perplexity, Gemini and Claude, with no Google AI Overviews. |
| Ease of use | C | No rating on record. Prompts are suggested for you, but there's a Brand Memory to fill in and Analytics and Search Console to connect. |
| Platforms and integrations | B | Web only, linked to Google Analytics, Search Console, Slack, HubSpot, Zoho CRM, Telegram, Gmail and Calendly, with an API from Pro. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Erlin is for
- Fits if you want AI tracking and article writing in one subscription, from Standard
- Works for teams that want visits from AI answers tied to leads through GA4
Who it is not for
- Not for you if you want to pay monthly, as every plan is billed yearly
- Skip it if Google AI Overviews matters, since it isn't among the engines listed
- Pricey if you need Claude or an API, which start at Pro for $397 a month
- Too light for writing on Starter, which has no content generation
- Watch out: there's no free trial; each plan opens with a 7-day trial that costs $7
Good to know
Good for
- Ecommerce, SaaS and B2B service firms tracking AI answers on a small budget
- Teams that want AI visibility tracking and article writing in one subscription

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
The plain part of Erlin you could make: long-form writing. What surrounds it you could not. The 5 things listed below take a company, not a weekend.
That makes this kind of software worth paying for, not this one in particular: 129 of the 157 other AI search visibility tools grade higher. It costs $564 a year.
What you could make
- Long-form writing: an app builder makes this well.
What you could not
- The same prompts asked of ChatGPT, Perplexity, Gemini and Google's AI answers every day, and the answers kept.
- A score built from what the top results for each keyword cover.
- A chatbot builder hooked into the messaging apps.
- A tracking script and a database that counts every visit.
- It plugs into other products, Google Analytics, Google Search Console and Slack among them, and has an API.
What this rests on. Erlin’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
