Coraltalk

What it does

Coraltalk is a voice-first AI platform designed for higher education to run oral assessments and personalized tutoring at scale. It enables educators to create AI-powered oral exams, role-play scenarios, and explanation-based assessments that verify real understanding in an era where written assignments can be easily generated by AI tools like ChatGPT. The platform works by having students respond out loud to questions that require reasoning, capturing authentic understanding that cannot be copy-pasted.

Teachers can create an AI teaching assistant in 3-5 minutes by uploading course content and setting Coral to reflect their own teaching style. They receive a unique link to share with students, who can ask unlimited questions anytime. Coraltalk offers three types of oral exams, 24/7 multilingual support, and integrates with Learning Management Systems (LMS) such as Canvas and Moodle without requiring replacement. The system provides instant insights into reasoning gaps, misconceptions, and confidence levels, allowing early intervention.

Key features include:

• Rubric-aligned oral assessment with adaptive questioning.
• Real-time misconception flags and confidence level indicators.
• Integration with Canvas and Moodle (others available on request).
• Privacy and security: SOC 2 Type I certified, GDPR compliant, HECVAT compliant, with a commitment to never use customer data to train models.
• Backed by LVLUP Labs, Elevate Women (The Firehood), Swiss EdTech Collider, and the NVIDIA Inception Program.

Who it is for

Coraltalk is designed for higher education professors and institutions, as well as corporate training and professional development contexts. It serves educators who need to verify student understanding in an AI-written era, enabling them to run oral assessments for large classes that would normally be impossible to scale. The platform is used by a range of institutions, as evidenced by testimonials from York University (MBA program), OpenScreenplay (corporate training), Lewis & Clark College (Psychology), and a private Ontario high school.

Student testimonials highlight that Coraltalk helps them understand material more deeply than traditional written assignments. The platform is particularly valuable for educators who want to assess reasoning and critical thinking, not just the ability to produce polished writing. It is also suitable for language learning, acting schools, and screenwriting classes, where customized role-play scenarios are needed.

Why it matters

In the current educational landscape, written assignments are no longer reliable evidence of learning. The website cites that 88% of assignments are written with AI, and 90% of learned material is forgotten within one week. Coraltalk addresses these challenges by:

• Shifting assessment from written to oral, making it impossible to fake understanding with AI-generated text.
• Boosting retention up to 90% through active learning and retrieval practice.
• Building real-world readiness through role-play and scenario-based practice (2/3 of students are reportedly unprepared for real life).
• Providing early intervention: seeing the struggle before students fall behind.

Before Coraltalk, teachers spent 6 hours grading essays that looked polished but lacked clarity. With Coraltalk, a 10-minute oral diagnostic provides real-time misconception flags, and a dashboard highlights at-risk students instantly. It replaces the need for live teacher assessments, offering substantial cost savings and scale. The platform ensures inclusive, culturally responsive assessment while celebrating each student's unique learning style.

Launch signal

Coraltalk has demonstrated early traction by winning the Rotman Spark Night People’s Choice Award 1st place and the Toronto Datamellon Ignite Pitch Battle 1st place. According to an EU-Startups article, Coraltalk’s CEO Melissa Morgan met an Italian distribution partner and secured a customer from the University of Malta at the EU-Startups Summit. The platform is also backed by notable programs and investors including LVLUP Labs, Elevate Women (The Firehood), Swiss EdTech Collider, and NVIDIA Inception. Multiple case studies (York University, OpenScreenplay, Lewis & Clark College) show real-world adoption and positive outcomes.

Brand and naming

The name "Coraltalk" evokes the idea of a coral reef—a vibrant, natural ecosystem where communication flows organically. The "Coral" component suggests authenticity, living structure, and interconnectedness, while "talk" emphasizes the core differentiator: voice-based conversation. The brand positions itself as the solution to the "AI-written era" problem, promising authentic assessment through spoken interaction. The visual identity uses gradients of purple, blue, and green, suggesting technology combined with organic growth. The tagline "Assess real understanding in an AI written era" directly addresses the pain point of educators who can no longer trust written assignments.
