## Brilliant

Brilliant takes a different approach to learning: rather than watching long videos or reading dense textbooks, you build understanding by solving interactive problems. Lessons break big ideas down into small visual steps, so concepts in algebra, calculus, statistics, logic and Python become intuitive. The platform is designed for self-paced learners from roughly middle-school level up to college and beyond, and it adds a new AI tutor called Koji who asks guiding questions and sketches on screen to help you find answers yourself.

Beyond pure math, Brilliant covers computer science fundamentals, programming, data analysis and how modern AI actually works, including neural networks, tokenization and model reasoning. Each track uses mastery assessments that adapt to your level, revisiting weak spots and serving targeted practice so progress is measurable rather than vague. Real-world examples, such as image filters or password security, connect abstract ideas to everyday technology.

The platform is also used by schools and families. It is accredited by ACS WASC, certified under the kidSAFE/COPPA program, and offers classroom and teacher programs so educators can assign adaptive lessons and homework. For individual learners, the app is available on web and mobile, with progress syncing across devices.

**Pricing & Plans:** Brilliant uses a freemium model: a limited free experience is available, while a Premium subscription unlocks the full course library and unlimited practice. Annual plans are the cheapest per month, and there are separate school/classroom plans.

- **Interactive problem-based lessons:** Learn math, science, CS and AI through short, visual exercises that build intuition step by step rather than passive video watching.
- **Koji AI tutor:** A visual, interactive tutor that works on a shared canvas, asks guiding questions and gives hints without simply revealing the answer.
- **Adaptive mastery assessments:** Quizzes and reviews adapt to your level, tracking what you have mastered and resurfacing topics that still need work.
- **Coding and CS foundations:** Write and run real code to learn programming logic, algorithms, data structures and debugging skills relevant to the AI era.
- **Courses for schools and families:** Accredited classroom programs let teachers assign adaptive lessons, with kidSAFE/COPPA-certified privacy protections.

**Strengths:** Hands-on, visual format makes abstract concepts easier to grasp; Access to the Koji AI tutor that guides rather than gives away answers; Accredited and kidSAFE/COPPA certified, suitable for schools and families; Works across web and mobile with syncing progress

**Limitations:** Full course library requires a paid Premium subscription; Not a replacement for formal instruction or credentials; Some advanced or niche topics are not covered deeply

## Grably

Grably is a multi-modal human interaction data research company. Rather than selling generic web scrapes, it positions itself as a lab that captures and models how people act, sense, decide, and communicate, then packages that into structured datasets for AI developers. Its site highlights backing from Techstars and partnerships with leading AI labs and technology companies.

The company organizes its offering into suites for image, video, audio, code, and text, alongside a catalogue of multi-modal conversational data. Publicly described assets include billions of sequential messages in more than 100 languages, thousands of hours of labelled sports footage, and tens of millions of medical studies. Each dataset is aimed at a specific modelling need, from LLM pretraining and multilingual coverage to embodied AI, temporal video understanding, speech, and document intelligence.

Grably also builds custom datasets for clients with niche goals, aligning anonymization, filtering, and delivery formats to internal research, legal, and infrastructure requirements. Delivery timelines vary by modality, and pricing is scoped per engagement, so prospective buyers discuss requirements directly with the team. The overall pitch is data quality and human-centred signal, not volume alone.

**Pricing & Plans:** Pricing is contact-based. Each dataset or custom project is quoted according to scope, modalities, and delivery requirements.

- **Multi-modal data suites:** Datasets covering image, video, audio, code, text, and conversational interaction for varied model-training needs.
- **Custom dataset design:** Buyer-scoped datasets with configurable anonymization, filtering, modalities, and delivery formats.
- **Multilingual coverage:** Conversational and text data spanning 100+ languages, including low-resource and underrepresented regions.
- **Structured, annotated content:** Signals that are aligned, annotated, and validated for cross-modality and scientific consistency.
- **Domain-specific corpora:** Specialized datasets for sports, medical records, documents, scientific literature, and code.

**Strengths:** Broad multi-modal and multilingual dataset catalogue; Custom dataset design with configurable anonymization; Enterprise and research-lab oriented delivery; Backed by a recognised accelerator program

**Limitations:** No self-serve pricing or instant purchase flow; Dataset access requires a sales conversation; Delivery timelines for rich modalities can span weeks
