Otterly.AI vs Rank Prompt (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 Rank Prompt if

• Fits if you run AI visibility for many clients and want reports under your name, from Agency at $119
• Works for teams that want the data in their own scripts, through the API or MCP on every plan

Look elsewhere if

• Tight if you publish a lot, since articles and audits eat the same credits as tracking, and credits don't roll over
• Skip it if a team needs logins on Starter, which is owner only
• Not for you if you want a trial, as the free plan is a one-off 10 credits for one report
• Watch out: Agent Mode runs on a small monthly AI budget, $5 to $25 by plan, topped up with credits
• Watch out: a prompt in four to six engines costs 2 credits, and white-label reports start at Agency

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.

Rank Prompt

• Everything is metered in credits that reset monthly and do not roll over; articles, audits and prospect searches draw from the same pool.
• The free plan is a one-off 10 credits, enough for one report; ongoing tracking needs a paid plan.
• Starter has no team seats beyond the owner; white-label reports start at Agency.
• AI agent use is billed against a small monthly dollar budget, topped up with credits.
