What Is Keywordly?
Keywordly is an all-in-one SEO content workflow platform built to automate research, clustering, writing, optimization, and auditing. The platform treats SEO as a continuous process where automation and AI-driven insights improve visibility across traditional search engines and emerging AI platforms alike.
Its core strength: an agentic AI-powered workflow that moves seamlessly from keyword research and clustering to content creation, optimization, audits, and AI visibility tracking. Brands use it to stay visible as search evolves.
What Is Frase.io?
Frase.io is an AI-powered research and content optimization platform centered on a full “AI Agent” that handles SEO and GEO content optimization, AI visibility tracking, site audits, SERP research, and API access. Every paid tier gets the full toolkit; pricing simply adjusts usage caps rather than features.
It positions itself as a research-first alternative to enterprise SEO suites, with a user base of over 30,000 content, SEO, and marketing teams backing its approach.
Feature Comparison: Deep Dive
Keyword Research and Clustering
Keywordly builds its workflow around automatically grouping related keywords using semantic and SERP-based clustering to surface content gaps and prioritize topics. It groups keywords based on actual search result overlap of 30% or more shared URLs. Frase.io takes a different angle, centering research around SERP analysis and question extraction that feeds directly into brief generation, leveraging insights from its large user base to inform research depth.
Winner: Keywordly. The dedicated clustering engine with content-gap detection gives teams a clearer topical roadmap than research alone.
AI Content Briefs and Writing
Keywordly transforms each keyword cluster into a structured brief with one core keyword, prioritized secondary terms, suggested H2/H3s, and FAQ ideas. Its AI writer then generates conversational or authoritative posts, creates topical maps, builds outlines, and applies on-page SEO best practices. Frase.io’s briefs are one of its most praised features: they’re generated in 90 seconds, include real-time SEO scoring, come with a built-in AI writer, and track GEO Score visibility across all plans.
Winner: Tie. Frase.io’s briefs are faster out of the box, but Keywordly’s cluster-to-brief-to-article pipeline eliminates manual handoffs for high-volume teams.
On-Page Optimization and SEO Scoring
Both platforms score content against top-ranking pages and suggest semantic improvements. Frase.io’s real-time 0-100 SEO scoring has been a core feature for years and reviewers frequently mention it. Keywordly focuses its optimization layer on rewriting content based on AI-powered suggestions, with the ability to import existing pages, optimize, and republish.
Winner: Frase.io. Its scoring interface has deeper NLP-driven granularity and a longer track record for editors chasing a single optimization metric.
AI Visibility and GEO Tracking
Keywordly’s LLM Visibility Tool shows where your brand appears in AI-generated responses across ChatGPT and Claude. It takes a step further by helping teams build authority on forums like Reddit and Quora that large language models rely on heavily. Frase.io also tracks AI visibility across ChatGPT, Perplexity, and Claude on every plan, a feature independent reviewers note is rare at this price point.
Winner: Tie. Both track AI-platform visibility. Keywordly’s forum-authority workflow differentiates it for brands chasing citations on Reddit and Quora, while Frase.io’s inclusion of Perplexity adds breadth.
Site Audits and Workflow Automation
Frase.io bundles SEO and GEO optimization, AI-visibility tracking, site audits, and API access into every tier, creating a genuine audit-and-refresh loop. Keywordly’s audit capability centers on semantic gap detection and content re-optimization rather than full technical site crawls.
Winner: Frase.io. Its comprehensive site audit feature is built for teams that need to refresh large volumes of existing pages alongside new content.
Pricing and Value for Money
Keywordly’s published entry pricing has historically started around $14 per month on a credit-based structure, with other sources citing plans near $29 depending on promotions. Frase.io charges $49/month for Starter, $129/month for Professional, and $299/month for Scale, dropping each by 20% with annual billing ($39, $103, and $239 respectively).
Winner: Keywordly. Lower entry-tier pricing is more accessible for solo bloggers and small teams. Frase.io’s volume-based model feels more predictable for high-output operations, though. For a more detailed feature breakdown, see An In-Depth Review of 10 AI SEO Tools (From Free to ….
Pricing Comparison
| Plan tier | Keywordly | Frase.io |
|---|---|---|
| Entry | From roughly $14 to $29/month depending on promotion | $49/month ($39/month annual) Starter |
| Mid-tier | Scales by credits, seats, and AI writing volume | $129/month ($103/month annual) Professional |
| Top tier | Higher-credit plans for agencies | $299/month ($239/month annual) Scale |
| Enterprise | Custom outreach for large teams | Custom quote |
| Trial/free access | Free demo available | 7-day free trial with no credit card |
Keywordly looks cheaper at first glance. However, its credit-based model has drawn complaints: reviewers note that credit limits burn fast, with 100 searches monthly on the $39/month plan, and essential features missing from lower tiers. The company has since adjusted the credit system to charge only 2 credits per research after user feedback. Frase.io sidesteps credit confusion on core research but introduces overage costs: extra articles run $4-$5 each and audits $0.40-$0.50 each once you exceed your plan’s cap.
