## 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

## Ghostwrite

Ghostwrite targets the daily friction of inbox work: you know roughly what you want to say but composing it properly takes time, and the same follow-ups keep coming back around. The extension adds a writing panel directly into your email client, so a few keywords or a short bulleted list becomes a complete, professionally worded message. Reply drafting is a single click, which is where most of the time savings come from for support and sales teams working through a queue.

Tone control is built in: you can switch between formal, friendly, concise and persuasive registers depending on the recipient, and the tool also cleans up grammar and spelling as it writes. Beyond one-off messages, you can save the outputs you like as reusable templates for cold outreach, follow-ups, meeting requests, job applications and support responses, turning repeatable emails into a few seconds of work.

It runs in the browser alongside Gmail, Outlook and Zendesk, so nothing changes about where or how your mail is stored. The publisher states that it does not store or share email content, and the extension is offered as a paid add-on with in-app purchases rather than a free utility. Because it depends on the host page layout of each webmail client, occasional breakage after those services redesign their interfaces is a normal risk for this category of extension.

**Pricing & Plans:** Paid Chrome extension with in-app purchases; the store listing flags optional paid features rather than a free tier. Install is free from the Chrome Web Store, with charges for usage or premium functionality handled inside the extension.

- **Full email generation from a few words:** Turn a short phrase or bulleted list into a complete, professional email, including cold outreach, applications and follow-ups.
- **One-click smart replies:** Ghostwrite reads the incoming message and drafts a contextually appropriate full reply in a single click.
- **Tone and style control:** Switch between formal, friendly, concise and persuasive registers so the same content fits different recipients and situations.
- **Grammar and spelling clean-up:** Text is corrected for spelling, grammar and clarity as it is generated, so nothing goes out with obvious mistakes.
- **Reusable AI templates:** Save generated messages as templates for recurring scenarios — follow-ups, outreach, meeting requests and support replies.

**Strengths:** Works directly inside Gmail, Outlook and Zendesk, so there is no new app to learn; One-click smart replies give the biggest time saving for high-volume inboxes; Tone presets and built-in proofreading keep the output professional; Reusable templates make common email scenarios nearly instant

**Limitations:** It is a Chrome-only browser extension, so desktop and native mail clients are out of scope; Being page-injected means it can break when Gmail, Outlook or Zendesk update their interfaces; Paid add-on with in-app purchases rather than a generous free plan
