Keyword research quality for SEO content
Discovery
How well the tool identifies, qualifies, clusters, and prioritizes keywords specifically for SEO content creation.
KeywordsPeopleUse
Strong question and long-tail discovery with clustering and content planning, with less conventional difficulty and backlink depth than a full SEO suite.
The official product combines query discovery, clustering, intent-led reports, and content briefs. https://keywordspeopleuse.com/
Otterly.AI
Prompt research helps map AI-search questions, but Otterly.AI is not a conventional keyword volume, difficulty, or clustering suite.
Automatic prompt research is documented at https://otterly.ai/features

Execution
How well the tool helps produce, optimize, or operationalize SEO content.
KeywordsPeopleUse
AI articles, briefs, outlines, topical maps and content optimization are provided, but publishing is not documented.

Context gathering
Grounding
How well the tool gathers the business, competitor, SEO, internal, third-party, and custom API context needed for differentiated recommendations and content.

AI-search / GEO
Visibility
How directly the tool helps teams improve visibility in AI answer engines and citation-oriented search journeys.
KeywordsPeopleUse
No explicit AI-search/GEO optimization feature is documented.
The official feature pages describe SEO research and AI writing, but make no AI-search/GEO claim: https://keywordspeopleuse.com/
Otterly.AI
Core product capability: multi-engine AI visibility, citations, brand coverage, sentiment, GEO audits, and recommendations.
The feature page explicitly covers AI Search Analytics, Domain Citation Tracking, Brand Visibility Index, Crawlability Checker, Content Audit, and GEO Optimization: https://otterly.ai/features
GEO readiness
Visibility
How ready the tool is for generative engine optimization: answer-engine visibility, citation likelihood, AI-search prompt surfaces, and content structures that AI systems can use.
KeywordsPeopleUse
No explicit generative-engine or AI-answer visibility tracking is documented.
The official content-optimization page documents Google Search Console metrics and filters, not generative-engine visibility: https://keywordspeopleuse.com/content-optimization-tool
Otterly.AI
Audits AI-bot crawlability, robots.txt, content readiness, structured data, and dynamic-content factors, with recommendations.

Diagnostics
How strong the tool is for crawling, audits, indexability, metadata, status codes, and technical site health.
KeywordsPeopleUse
Some page crawling and content understanding exist, but no full technical audit is documented.
The content page says it crawls and understands each website page and uses embeddings/cosine similarity: https://keywordspeopleuse.com/content-optimization-tool
Otterly.AI
GEO audits surface machine-readability issues, but no full technical SEO crawler is documented.
Official features focus on GEO audit actions rather than site-wide technical crawling: https://otterly.ai/features
Publishing workflow
Operations
How well the tool moves work into CMS, publishing, approvals, or automated production workflows.
KeywordsPeopleUse
It generates handoff-ready briefs and AI content, but no native CMS publishing workflow is documented.
The AI page says briefs are ready to hand to a content creation team and describes automated generation: https://keywordspeopleuse.com/ai-content-generator
Otterly.AI
Exports, API, recommendations, and content briefs can support a workflow, but native drafting-to-publishing is not documented.
The official feature list documents Detailed Reports & Exports and Content Briefs, without a CMS publishing feature: https://otterly.ai/features

Value accessibility
Buying
How easy it is for a team to reach value relative to pricing, setup complexity, and required expertise.
KeywordsPeopleUse
Low entry price, trial, free clustering allowance, and annual discount make it accessible.
Pricing lists a $15/month Lite plan, a 7-day full-access trial, and 30-day guarantee; clustering says the first 150 keywords are free: https://keywordspeopleuse.com/pricing and https://keywordspeopleuse.com/keyword-clustering-tool
Otterly.AI
A no-card trial and $29 entry price improve access, but the product is paid and important engines/features require add-ons or higher tiers.
The pricing page shows Lite at $29/month and the official pricing help article confirms a no-card trial and paid add-ons: https://otterly.ai/pricing and https://help.otterly.ai/pricing-of-otterlyai
Free tools
Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.

Estimated customer scale
Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.
KeywordsPeopleUse
The company publishes a substantial first-party user claim, but it is not independently audited here.
The homepage states 'Powering 15,000+ users in 150 countries in 64 languages': https://keywordspeopleuse.com/
Otterly.AI
The site claims 40,000+ marketing professionals worldwide, but this is a professional-user claim rather than an auditable paying-customer count.
The official homepage states 'Used by 40,000+ marketing professionals worldwide' and displays customer logos/case studies: https://otterly.ai/
Agent readiness level
Automation
How ready the product is to operate as or inside an AI agent workflow, based on tracked subcriteria for autonomy, controls, integrations, memory, and evaluation.
KeywordsPeopleUse
Strong API and MCP support enables programmatic and AI-chat access to research functionality.
The MCP page provides an MCP endpoint/configuration for Claude Desktop and says live research data is available in an LLM: https://keywordspeopleuse.com/mcp-server
Otterly.AI
MCP, API, and write actions fit agent workflows, but autonomous content execution, approval governance, and learning loops are limited.
The official MCP and API expose prompt, tag, and audit actions: https://help.otterly.ai/does-otterlyai-have-an-mcp and https://otterly.ai/blog/otterlyai-public-api-claude-skill-launch/
Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
KeywordsPeopleUse
Alerts, bulk search, daily syncing, AI templates and exports automate parts of research and optimization, but human review and publishing remain necessary.
The homepage documents scheduled Search Alerts that email newly found questions and keywords; the content page documents daily updates: https://keywordspeopleuse.com/ and https://keywordspeopleuse.com/content-optimization-tool
Otterly.AI
Automates daily monitoring, prompt generation, recommendations, and on-demand audit actions, but consequential content/publishing changes remain human-controlled.
OtterlyAI documents daily tracking, automatic prompt research, actionable recommendations, and MCP write actions limited to prompts, tags, and GEO audits: https://otterly.ai/features and https://help.otterly.ai/does-otterlyai-have-an-mcp
