Bersyn vs Otterly: An honest comparison of two GEO platforms

Otterly AI and Bersyn both claim to solve the same problem: showing B2B teams how AI assistants describe their product to buyers, and giving them a path to improve it. They reach that problem from different angles, charge very different prices, and suit different buyers. This page is the honest comparison.

Disclosure first. Bersyn is our product. We have done the research below in good faith — pricing pulled from Otterly's public pages, features verified against their documentation and third-party reviews — and we list the cases where Otterly is the better choice. If you would rather hear about Otterly from Otterly, their site is at otterly.ai. This page is for people deciding between the two.

TL;DR

Otterly is the right call if you are a marketing team inside a larger company, already use Semrush, want a tool that also covers Microsoft Copilot and Google AI Overviews, and are comfortable paying $300+/month once you add the AI Surfaces that matter to your buyers.
Bersyn is no longer a self-service alternative to compare on price. The founding-beta tier this page was written around has been withdrawn; Bersyn now measures a market — one category, one country, one language — for agencies and design partners, reports counts one AI Surface at a time, and produces no score. See bersyn.com/pricing.

The honest summary: Otterly is the more established product in a slightly broader category. Bersyn is the more focused product for the specific buyer who needs all four LLMs covered without surprise add-on charges and wants the corrective content generated, not just measured.

Where Otterly is better

Surface breadth. Otterly monitors Microsoft Copilot and Google AI Overviews, which Bersyn does not yet. If your buyers research products inside Microsoft 365 or you care a lot about Google's AI Overviews appearing above traditional search results, Otterly covers ground we do not.

Semrush integration. Otterly plugs into the Semrush App Center, so if your team already lives inside Semrush for keyword research and rank tracking, the GEO data lands in the same workflow. Bersyn is a standalone product — useful as a complement to traditional SEO tools, not an extension of them.

Maturity. Otterly has been in market longer, has a customer base of established marketing teams, and has the polish that comes from many iterations on its core monitoring workflow. If "established tool with a track record" matters in your evaluation, that goes to Otterly.

Tier scaling for enterprise. Otterly's pricing goes up to a $989/month Pro tier with more prompts and seats, which suits larger marketing teams. Bersyn's founding beta was a single low-priced tier and has been withdrawn.

Where Bersyn is different

This section described a product that is no longer sold, and has been replaced rather than quietly edited. What it said — a $49/month founding-beta tier, a one-time audit, generated Patches, a single blended visibility figure — was true of Bersyn in mid-2026 and is not true now. Bersyn withdrew that offer after turning its own method on itself and finding numbers it could not defend, and nothing has replaced it that would be honest to compare on price.

What Bersyn does today, stated without a number attached to it:

It records real answers from ChatGPT, Claude, Gemini and Perplexity to a fixed set of buyer questions, several times each, and keeps every answer.
It reports counts one AI Surface at a time, each with its own denominator, and refuses to blend them into a single figure — because on the evidence it has, the four assistants disagree, and one number would describe none of them.
Measurement covers a market, not a customer: one category, one country, one language. Every company in that market reads the same recorded answers.
It produces no score, no grade and no rank, and it does not claim that any change caused any difference between two measurements.

There is no self-service purchase, no instant scan, and no price to quote. New markets are measured for agencies and design partners. The current position, in full, is at bersyn.com/pricing.

The Otterly research above is left exactly as published. It was gathered in good faith at the time and is still the more useful half of this page.

Who should choose which

Choose Otterly if you need a product you can buy today. Everything in the Otterly sections above still applies, and Bersyn is not currently a self-service alternative to it.

Talk to Bersyn if you work with clients in a category you want measured and you would rather have the recorded answers than a summary of them. Say which category, country and language: bersyn.com/pricing.

How a market gets measured today

If you are reading this, you are probably trying to decide whether AI visibility is a problem worth solving for your product. The best answer to that question is not a comparison page — it is a measurement of your own category.

Bersyn is not sold self-service today, so there is no scan to run from this page. Measurement covers a market — one category, one country, one language — and every company in that market reads the same recorded answers, so a market is measured once and each company in it reads that measurement. If you work with clients in a category you want measured, say which category, country and language: bersyn.com/pricing.

If you decide Otterly fits your situation better, that is fine. The point is to make the decision with real data, not on either of our marketing pages.
