Otterly.AI vs Prominara (2026): which should you pick?

Pick Otterly.AI if

• Fits if a daily read on ChatGPT, Perplexity, AI Overviews and Copilot is what you need
• Works for agencies that brand client reports through Looker Studio, from Standard

Look elsewhere if

• Skip it if Gemini, AI Mode or Claude matter to you, as they're paid add-ons on every plan, and all seven engines add $227 a month on Standard
• Not for you if you need white-label reports, as there aren't any
• Tight if you start on Lite, with 15 prompts, one workspace, no API or MCP, and no extra prompt packs
• Pricey if you outgrow Lite, as Standard is $160 a month yearly and extra prompts are $99 per 100, with 300 at most before Premium at $422
• Watch out: Claude is tracked through its API using the Haiku model, and crawler analytics needs server log files you upload

Pick Prominara if

• Fits if you want to know whether a change moved AI answers, rather than guessing from the trend
• Works for agencies reporting to a few clients under their own brand, from Pro

Look elsewhere if

• Skip it if you need daily checks, as prompts are re-checked weekly at most
• Tight if you start on Starter: 15 prompts on 2 of the 5 AI surfaces, checked every two weeks
• Pricey if you want all five surfaces or white-label reports, which start on Pro at $149 a month
• Too light for agencies with more than 3 clients, as Agency includes 3 workspaces and more means asking sales
• Watch out: plans bill monthly, and yearly billing is arranged by email with no saving stated

Otterly.AI

• Google AI Mode and Gemini cost $9, $59 or $149 a month each by plan, and Claude $29, $109 or $439, so all seven engines on Standard add $227 a month.
• Google AI Mode, Gemini and Claude are paid add-ons on every plan; Claude is tracked through its API using the Haiku model.
• Lite has one workspace; extra prompts are sold in packs of 100 on Standard and Premium only.
• There is no white-label option; the Looker Studio connector is the suggested way to brand client reports.

Prominara

• Starter covers only 2 of the 5 AI surfaces, checks every two weeks rather than weekly and has no white-label reports.
• Prompts are re-checked weekly at most, not daily; the vendor says this is deliberate to judge changes against noise.
• Plans are billed monthly; annual billing is arranged by email, and the page states no saving for it.
• Agency includes 3 client workspaces; more clients means asking sales to raise the limits.

Prompt tracking on five AI surfaces

Puts tracked buyer questions to ChatGPT, Perplexity, Gemini, Google AI Overviews and AI Mode, counting mentions and citations apart, with position and sentiment.

Source gaps and playbooks

Ranks the pages each answer cites and, where competitors are cited and you are not, writes a playbook with steps, effort and risks.

Share of voice

Shows how often AI names you against each competitor, engine by engine, counting only prompts that do not name you, with a range on each figure.

Site audit and generators

Scores more than 40 page and site checks into a 0 to 100 GEO score and generates llms.txt, robots.txt, sitemap and JSON-LD schema from the crawl.

Impact measurement

Log a change and it compares the prompts you worked on with ones you did not touch over 7, 14 and 28 days, giving a probability rather than a yes or no.
