speaking.app is an AI-powered public speaking and interview practice platform for individuals, teams, and training programs. Rehearse pitches, job interviews, presentations, and impromptu speaking, and get objective feedback before the real thing.

How it works: record or upload a spoken response and get AI speech analysis on pacing (words per minute), pauses, filler words, structure, and clarity, plus a digital Ah-Counter for Toastmasters-style tracking. Smart Rewrite detects which of 15 speech frameworks (STAR, PREP, Story Arc) your answer follows and restructures it.

Pitch practice (Pro): a dedicated analysis maps a startup or investor pitch to the 11 elements investors expect (hook, problem, solution, market, traction, business model, team, the ask, vision), rates each, and returns an investor-style verdict from "Strong Yes" to "Pass".

Interview practice: 1,400+ questions across 90+ curated sets for specific companies (Amazon, Google, Meta, McKinsey, Goldman Sachs), roles, accelerators (Y Combinator, Techstars), and admissions (MBA, medical, law).

For organizations: accelerators, universities, and coaching firms manage seats, assign practice, and track progress from a coaching dashboard.

Free tools: a speech timer with Toastmasters-style green, yellow, and red timing lights (full-screen, screen stays awake, per-speaker log), free with no account, at speaking.app/tools/speech-timer.

Not a live copilot: speaking.app is rehearsal software you use before the moment, not during a real interview or call.

Plans: free tier; Pro at $19.99/month or $99.99/year; per-seat Workspace; one-time Pro Passes for cohorts. Includes a free public Champions Library of analyzed famous speeches at speaking.app/speeches.

KnowCSS features and specs

  • Interactive CSS Learning
    KnowCSS provides an interactive way to learn and practice CSS properties and concepts, making it easier for beginners to understand how CSS works through hands-on experimentation.
  • Quick Reference Tool
    The site serves as a handy quick-reference tool for CSS properties, allowing developers to quickly look up syntax, values, and usage examples without digging through lengthy documentation.
  • Visual Demonstrations
    KnowCSS offers visual demonstrations of CSS properties, helping users see the immediate effect of different CSS values, which accelerates understanding of styling concepts.
  • Free to Use
    The platform is freely accessible, making it a cost-effective resource for students, self-taught developers, and anyone looking to improve their CSS skills without financial commitment.
  • Clean and Simple Interface
    The website features a clean, straightforward interface that is easy to navigate, allowing users to focus on learning CSS without being distracted by cluttered design or excessive advertisements.

Possible disadvantages of KnowCSS

  • Limited Depth of Content
    KnowCSS may not cover advanced CSS topics in sufficient depth, which means experienced developers may find the resource too basic for their needs and would need to supplement with other resources.
  • Limited Community and Support
    Compared to larger platforms like MDN Web Docs or CSS-Tricks, KnowCSS has a smaller community, meaning fewer discussions, forums, or peer support for troubleshooting issues.
  • Narrow Scope
    The site focuses specifically on CSS, so users looking for a comprehensive web development learning platform covering HTML, JavaScript, and other technologies will need to use additional resources.
  • Less Frequently Updated
    Smaller niche tools like KnowCSS may not be updated as frequently as major documentation sites, potentially missing coverage of the latest CSS features and specifications.
  • Limited Real-World Project Examples
    The platform may lack complex, real-world project examples that demonstrate how CSS properties work together in practical scenarios, which can leave a gap between learning individual properties and applying them in production.

Analysis of speaking.app

Overall verdict

  • Speaking.app appears to be a niche public speaking/communication skills platform. Without extensive independent reviews or track record data, it's best assessed cautiouslyโ€”suitable for casual skill-building but not verified as a top-tier professional training solution.

Why this product is good

  • Focuses specifically on public speaking and communication improvement
  • Likely offers structured exercises or courses for skill development
  • May provide a convenient app-based format for practicing on your own schedule
  • Could be useful for beginners wanting low-pressure practice tools

Recommended for

  • Individuals looking for casual, self-paced public speaking practice
  • Beginners wanting to build basic confidence before formal training
  • Users seeking a supplementary tool alongside other speech coaching
  • Those exploring low-cost or free options before investing in premium coaching services

Analysis of KnowCSS

Overall verdict

  • KnowCSS is a lightweight, no-frills CSS framework that helps developers quickly style HTML documents without writing custom CSS or dealing with class-heavy frameworks, making it a decent choice for simple, semantic styling needs, though it lacks the extensive ecosystem, community support, and advanced features of more established frameworks like Bootstrap or Tailwind CSS.

Why this product is good

  • Provides classless or minimal-class styling that works directly on semantic HTML elements
  • Lightweight footprint reduces page load times compared to bulkier frameworks
  • Simple to integrate for quick prototypes or small projects without a steep learning curve
  • Encourages clean, semantic HTML markup rather than div-heavy class-based structures

Recommended for

  • Developers building small to medium-sized websites who want quick styling without writing custom CSS
  • Beginners learning HTML/CSS who want to see immediate visual results with minimal setup
  • Projects prioritizing semantic HTML and minimal class usage
  • Quick prototypes, documentation sites, or internal tools where extensive customization isn't required

Questions & Answers

As answered by people managing speaking.app and KnowCSS.

What's the story behind your product?

speaking.app's answer

speaking.app began with a personal realization. Its founder, Bjarte Sunde, an engineer by training, found that in a world increasingly shaped by AI, the skill that mattered most was still an old one: speaking clearly and confidently when it counts. While working on his own communication, he wanted honest feedback and a private way to practice, without an expensive coach and without waiting until the moment had already passed.

The product is built on a simple belief: how you come across in an interview, a pitch, or on stage should not come down to luck or budget. Everyone deserves a place to rehearse, hear how they actually sound, and improve before it matters. What began as a personal tool is now used by individuals, founders, students, and organizations to turn high-stakes speaking from something you hope goes well into something you have prepared for. Built in Dublin by Prosody Ltd, speaking.app is working toward a future where confident communication is something anyone can develop, not a privilege of the few.

What makes your product unique?

speaking.app's answer

speaking.app analyzes both how you speak and what you say, then coaches you until it becomes second nature.

  • Delivery analysis on every session: pacing (words per minute), pauses, filler words, and clarity.
  • Smart Rewrite detects which of 15 speech frameworks (such as STAR or PREP) your answer is closest to, scores how well you follow it, and rewrites it in that structure.
  • Founder pitch analysis maps a startup or investor pitch to the 13 elements investors listen for, rates each, and returns an investor-style verdict from Strong Yes to Pass.
  • Coaching feedback after every session tells you what to work on next, so each practice run has a clear focus.

Most tools stop at delivery metrics. speaking.app tells you what to fix, shows you how, and helps you rehearse it until it sticks.

Why should a person choose your product over its competitors?

speaking.app's answer

Choose speaking.app because it does more than measure your delivery. It helps you fix it and rehearse until you are ready.

  • It goes past delivery metrics. Beyond pacing and filler words, you get structural feedback and an AI rewrite of what you actually said, so you improve the substance, not just the surface.
  • It coaches you, then you iterate. After each session it tells you what to work on next, so every practice run has a focus and progress compounds.
  • It is built for specific, high-stakes moments. A dedicated pitch analysis for founders (the 13 elements investors listen for, with a verdict), plus 1,400+ real interview questions for named companies, roles, accelerators, and admissions.
  • It works solo or across a whole program. Practise on your own, or run a cohort from a coaching dashboard (accelerators, universities, coaching firms).

It is practice software for getting genuinely better beforehand, not a live in-call copilot.

How would you describe the primary audience of your product?

speaking.app's answer

speaking.app is for people with a high-stakes speaking moment coming up, and the organizations that train them.

  • Individuals: job seekers rehearsing interviews, startup founders preparing pitches and demo day, and professionals practising presentations and public speaking.
  • Organizations running structured practice programs: accelerators, universities, and coaching firms that use a coaching dashboard to manage participants and track progress.
  • Toastmasters and clubs: members use the free filler-word Ah-Counter and speech timer to run and time their meetings, no account needed.

Which are the primary technologies used for building your product?

speaking.app's answer

speaking.app is a modern web application. There is nothing to download or install.

  • Proven, industry-standard stack: Next.js and React on the front end, Python (FastAPI) on the back end.
  • AI at the core: speech is transcribed with AI speech-to-text; the analysis, coaching feedback, and Smart Rewrite are powered by large language models.
  • Runs anywhere: works in any browser as a Progressive Web App (PWA), installable on any device.
