We make Seen42, so read this comparison with that in mind. Competitor details come from their own pages, linked below with the date we checked them. Plans change, so confirm the current details before you buy.
What OtterlyAI does
OtterlyAI monitors AI search answers for your prompts and reports brand mentions, citations, sentiment and competitor share of voice. Its Lite plan costs $29 a month for 15 prompts and includes Google AI Overviews, ChatGPT, Perplexity and Microsoft Copilot. Gemini, Google AI Mode and Claude are paid add-ons on every plan; on Lite they cost $9, $9 and $29 a month. Standard ($189) and Premium ($489) raise the limit to 100 and 400 prompts.
What Seen42 does
Seen42 checks your prompts on ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews, explains where competitors are named instead of you, and builds and hosts comparison, facts and guide pages from your own facts. Paid plans are Starter $39 (15 prompts, 5 pages a month), Growth $89 (25 prompts, 8 pages) and Pro $189 (50 prompts, 15 pages). The Free plan runs one check of 10 prompts on ChatGPT and Gemini when you sign up.
Where they differ
- Price per prompt. OtterlyAI is cheaper per prompt.
- Assistants. With Gemini and Claude added, OtterlyAI Lite costs more than Seen42 Starter. OtterlyAI covers Microsoft Copilot, which Seen42 does not.
- After the report. OtterlyAI audits your content and gives you a ranked list of fixes, and its free tools draft articles and landing pages. Seen42 builds the page for a gap from your own facts, checks it and hosts it.
When OtterlyAI is the better fit
Choose OtterlyAI if you want to track many prompts at a low price, need Microsoft Copilot, and write and publish pages yourself.
When Seen42 is the better fit
Choose Seen42 if you want Gemini and Claude included, and you want the page for each gap built, checked and hosted rather than added to a to-do list.
