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

Pick Mentionary if

• Fits if you want to find which outside sites AI answers rely on in your market
• Works for small marketing teams starting out, with a 14-day trial and no card

Look elsewhere if

• Skip it if you need daily tracking, as Starter and Professional scan weekly and daily scans come with Agency
• Watch out: the pricing page doesn't say which 3 platforms Starter covers or which 5 Professional does
• Pricey if you need the API, which starts at Agency for $799 a month billed yearly
• Tight if you watch more than two rivals, as Starter allows 2 competitors and 200 scans a month

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

Mentionary

• There is no free plan, and each plan caps monthly scans; one scan is one prompt run on one platform.
• Starter covers 3 platforms and Professional 5, but the pricing page does not say which ones; the platform page lists six, including Copilot and You.com.
• API access starts at the Agency plan, $799 a month billed annually; lower plans get data exports only.
• Starter and Professional scan weekly; daily scans come with 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.
