Free Marketing Tools
10 free tools across email, LinkedIn, ad copy, and personality assessment. No signup. No credit card. Most return a result in about a minute.
Every tool below uses the same multi-framework engine that powers the SEMalytics platform: Engagement, Personality (OCEAN, the Big Five model; Costa & McCrae, 1992), Strategic Clarity, and Framing analysis (full citations at /science/). The free tier covers the diagnosis with daily-limited analyses; the paid tier adds iterative rewrites and tone calibration (tiers on the pricing page). Daily limits keep the free tools sustainable to run.
Paste any draft. Get a 1-10 score across 4 frameworks, the dimension that's strongest, and the dimension that's broken, before you send or publish.
Subject Line Tester
Score any email subject line across 5 OCEAN dimensions. Get the per-dimension fix designed to lift open rates before you send (scores are SEMalytics diagnostics, not guarantees of campaign results).
FreeA/B Subject Line Comparator
Paste two subject lines side-by-side. See which dimension each one activates and which actually fits your audience, not just which "feels" better.
FreeCold Outbound Analyzer
Paste a full cold email or DM. Get a coverage check that flags subject-to-body mismatches and the dimensions your draft is missing.
FreeLinkedIn Post Analyzer
Score a LinkedIn post draft before publishing. Check whether your hook, structure, and CTA match your target audience's profile.
FreeAd Copy Analyzer
Paste a Google or Facebook ad. Get a 4-framework score against your target audience's personality, before you push spend.
Personality & Profile Tools
Self-assessments and profile inference tools built on the OCEAN (Big Five) framework, the same model SEMalytics uses to match content to audience. DISC (rooted in Marston, 1928, Emotions of Normal People) and MBTI-style type results (Myers & Briggs; Myers et al., 1998, MBTI Manual, 3rd ed., Consulting Psychologists Press) are translated onto the Big Five dimensions because the five-trait model is the most extensively validated in personality psychology (Costa & McCrae, 1992).
LinkedIn Profile Analyzer (OCEAN)
Paste a LinkedIn profile bio. Get estimated Big Five personality dimensions and buyer persona insights to inform B2B outreach.

20-question self-assessment. Discover your OCEAN profile and how your personality shapes the way you write, sell, and persuade.
FreeDISC Personality Assessment
24-question DISC assessment. Discover your primary + secondary behavioral styles with an OCEAN translation for buyer matching.
FreePersonality Type Test
28-question personality type test. Discover your 4-letter type across Jungian dimensions (Jung, 1921/1971, Psychological Types) with an OCEAN Big Five translation.
