Verdict
Research depth
Discovery
How well the tool supports keyword, competitor, SERP, backlink, or market research before execution.

Read the full reviews: Otterly.AI and Screpy.
Screpy

Feature directory lists Keyword Research, SERP Analysis, Organic Keywords, Competitor Ads, Backlink Checker, Referring Domains, and Search Console: https://screpy.com/features/
Keyword research quality for SEO content
Discovery
How well the tool identifies, qualifies, clusters, and prioritizes keywords specifically for SEO content creation.
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
Screpy
Provides ideas, intent, volume, CPC, trends, and content-brief linkage; official detail is positive but not evidence of breadth comparable to specialist databases.
Screpy says Keyword Research finds ideas, reviews intent, and connects demand with pages, articles, and campaigns: https://screpy.com/feature/keyword-research/
Content execution
Execution
How well the tool helps produce, optimize, or operationalize SEO content.
Otterly.AI
Audits, recommendations, and briefs guide changes, but the product does not draft and publish full content workflows.
Official features describe recommendations, GEO audits, and content briefs: https://otterly.ai/features
Screpy
Generates queued article outlines/first drafts and Markdown for review, but does not claim autonomous publishing or optimization execution.
AI Article Generator creates drafts from titles/briefs and requires review before publishing: https://screpy.com/feature/ai-article-generator/
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.
Otterly.AI
Uses tracked prompts, competitors, cited domains, URLs, markets, and AI responses as context; custom company-data grounding is not documented.
Brand reports benchmark competitors and citation sources, while the MCP exposes raw responses, prompts, citations, filters, and recommendations: https://help.otterly.ai/does-otterlyai-have-an-mcp
Screpy
Uses crawled pages, Search Console data, ranking context, and project-level website data to prioritize opportunities.
Quick Wins is described as turning crawl and Search Console data into prioritized technical, content, and ranking opportunities: https://screpy.com/features/
AI-search / GEO
Visibility
How directly the tool helps teams improve visibility in AI answer engines and citation-oriented search journeys.
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
Screpy
Tracks AI mentions, citations, sources, prompts, and competitor share of voice across monitored AI answers.
AI Visibility feature explicitly lists mentions, citations, sources, prompts, and competitor share of voice: https://screpy.com/feature/ai-visibility/
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.
Otterly.AI
Audits AI-bot crawlability, robots.txt, content readiness, structured data, and dynamic-content factors, with recommendations.
The official MCP documentation article lists crawlability, robots.txt, bot access, AI-readiness, structural and dynamic-content scores: https://help.otterly.ai/does-otterlyai-have-an-mcp
Screpy
Has AI visibility monitoring and an SEO MCP, but official pages do not establish broad autonomous optimization for generative search.
AI Visibility monitors AI answers and SEO MCP exposes workflows to assistants: https://screpy.com/feature/ai-visibility/ and https://screpy.com/feature/seo-mcp/
Technical SEO
Diagnostics
How strong the tool is for crawling, audits, indexability, metadata, status codes, and technical site health.
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
Screpy
Strong explicit technical suite spanning audits, crawling, status/redirects/canonicals, broken links, image SEO, Core Web Vitals, PageSpeed, uptime, and index status.
Official feature directory documents the technical modules and their functions: https://screpy.com/features/
Publishing workflow
Operations
How well the tool moves work into CMS, publishing, approvals, or automated production workflows.
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
Screpy
Supports reviewed Markdown draft output, but no official native CMS publishing workflow is documented.
The article feature says users review Markdown output before publishing: https://screpy.com/feature/ai-article-generator/
Measurement & tracking
Measurement
How well the tool monitors rankings, content performance, visibility, or ongoing SEO progress.
Otterly.AI
Deep measurement includes daily prompt tracking, mentions, coverage, position, citations, sentiment, share of voice, history, exports, and agent analytics.
The feature page lists daily citation/mention tracking and visibility metrics; pricing lists Agent Analytics event allowances: https://otterly.ai/features and https://otterly.ai/pricing

Value accessibility
Buying
How easy it is for a team to reach value relative to pricing, setup complexity, and required expertise.
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
Screpy
Transparent low displayed entry price, free trial, and three clear tiers make access relatively straightforward, though key modules are gated.
Pricing shows Pro $6/month, Max $15/month, Ultra $30/month and a 7-day trial: https://screpy.com/pricing/
Free tools
Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.
Otterly.AI
A free trial exists, but no permanently free standalone tool is documented on the official pages reviewed.
The official site says Free trial/no credit card required and links to Start for Free, while pricing lists paid plans: https://otterly.ai/features and https://otterly.ai/pricing
Screpy
The official site provides several free standalone SEO tools, but they are separate tools and do not imply full platform access.
Screpy lists Website Analyzer, Google Rank Checker, SEO Report Generator, SERP Competitor Research, and Robots.txt Tester under Free SEO Tools: https://screpy.com/
Estimated customer scale
Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.
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/
Screpy
Official site displays ten named trust logos, but provides no customer count or independently verifiable scale metric.
The homepage trust section names Uber, Philips, FedEx Express, Bosch, Champion, Iconfinder, T-Mobile, Carrefour, Stanley, and Skoda: https://screpy.com/
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.
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/
Screpy
SEO MCP, REST API, AI-assistant integrations, and n8n provide meaningful agent connectivity, but the official material does not demonstrate broad end-to-end agent autonomy.
Screpy documents SEO MCP/API and integrations with ChatGPT, Claude, Perplexity, Gemini, Cursor, GitHub Copilot, and n8n: https://screpy.com/feature/seo-mcp/ and https://screpy.com/integrations/
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.
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
Screpy
Quick Wins and AI-assisted workflows prioritize and draft work, while review and publishing control remain with users.
Quick Wins prioritizes next actions and the article generator requires review, editing, fact-checking, and publishing control: https://screpy.com/features/ and https://screpy.com/feature/ai-article-generator/
