AI Interview Practice
5 Free Sessions, No Credit Card

EchoPitch is an AI presentation coaching platform that helps professionals overcome presentation anxiety through private, low-stakes practice. Using multimodal emotion intelligence, it analyses 44 facial Action Units based on the Facial Action Coding System (FACS) developed by psychologists Paul Ekman and Wallace Friesen, combined with voice pattern analysis and the Valence-Arousal-Dominance (VAD) emotional model developed by Albert Mehrabian. Research shows that 75% of people experience some degree of public speaking anxiety (Kessler et al., 2005, Archives of General Psychiatry). EchoPitch addresses this by providing objective, measurable feedback on trust signals, credibility indicators, and conviction patterns — the subconscious cues that audiences use to evaluate speakers. Unlike practicing alone in front of a mirror, AI-powered practice delivers the specific feedback needed to build genuine confidence before high-stakes interviews, sales calls, and investor pitches.

EchoPitch uses EchoDepth, Cavefish's multimodal emotion intelligence platform, to analyse your presentation in real-time across three signal layers. First, facial signal analysis tracks all 44 FACS Action Units — micro-expressions like AU6 (cheek raiser, indicating genuine engagement) and AU17 (chin raiser, signalling doubt) — at multiple frames per second. Second, these signals are mapped to VAD coordinates to derive continuous Valence (positive/negative), Arousal (calm/activated), and Dominance (controlled/submissive) readings. Dominance is the strongest predictor of perceived speaker confidence. Third, voice analysis measures pace, volume consistency, pitch variation, and filler word frequency against research-backed optimal ranges. The combined analysis produces actionable feedback on exactly when and why your confidence dropped, correlated with specific moments in your delivery. This methodology is grounded in over 50 years of peer-reviewed emotion science.

Your privacy is protected by design. EchoPitch processes facial and behavioural data under GDPR Article 6(1)(a) — explicit user consent. Your personally identifiable data is never used to train AI models, and all recordings remain private to your account with enterprise-grade AES-256 encryption. Cavefish Ltd operates under UK Information Commissioner's Office (ICO) registration ZB915633 and Companies House registration 15127122. You maintain full control over your data: export it anytime, delete individual sessions, or request complete account deletion. Video recordings are processed in real-time and can be configured to not be stored after analysis. For enterprise deployments, additional compliance certifications and data residency options are available.

Monthly (£29/month) is a recurring subscription ideal for ongoing interview preparation or continuous presentation improvement. You receive 50 practice sessions per month that reset on your billing date, plus full access to confidence analysis, job-tailored feedback, and attempt comparison features. One-off (£35) is a single payment for 50 practice sessions total with no auto-renewal — designed for professionals with a specific upcoming presentation, interview, or pitch who want focused preparation without commitment. Both plans include identical AI analysis capabilities. The Annual plan (£290/year) offers the best value with unlimited sessions, priority support, per-segment timeline analysis, and LinkedIn interviewer research features. Choose based on whether you need short-term intensive practice or ongoing development.

No specialised equipment is required. EchoPitch runs entirely in your web browser using your device's built-in camera and microphone. It works on desktop computers, laptops, tablets, and mobile devices — any device capable of video calls will work for practice sessions. For optimal analysis quality, we recommend good lighting (natural daylight or front-facing lamp), positioning your camera at eye level, and using a quiet environment to ensure clear audio capture. A stable internet connection of at least 5 Mbps is recommended for real-time analysis. No downloads, plugins, or installations are needed. The platform supports Chrome, Firefox, Safari, and Edge browsers. Enterprise deployments can integrate with existing video conferencing infrastructure if required.

After using your 5 free practice sessions, your account remains active with access to view past session recordings and analysis results. You can continue using basic features, but new practice sessions require upgrading to a paid plan. EchoPitch never charges automatically after a free trial — you explicitly choose when and whether to upgrade. When you do upgrade, all your previous practice history is preserved, allowing you to track long-term improvement from your very first session. If you're preparing for a specific interview or presentation, the One-off plan provides focused practice without ongoing commitment. For career-long communication development, Monthly or Annual plans offer the most value.
