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.

React Engine features and specs

  • Isomorphic rendering
    React Engine enables both server-side and client-side rendering of React components, providing a seamless isomorphic/universal JavaScript experience. This allows for faster initial page loads and better SEO while maintaining rich client-side interactivity.
  • Express.js integration
    React Engine is designed as a view engine for Express.js, making it easy to integrate React into existing Express-based applications with minimal configuration. It follows familiar Express conventions for setting up view engines.
  • Built-in React Router support
    The library comes with built-in support for React Router, enabling developers to easily set up server-side and client-side routing without complex manual configuration.
  • PayPal backing
    React Engine was developed and maintained by PayPal, which provided credibility and ensured it was battle-tested in a large-scale production environment before being open-sourced.
  • Simplified setup
    The library abstracts away much of the complexity involved in setting up server-side rendering with React, reducing boilerplate code and allowing developers to get a universal React application running quickly.

Possible disadvantages of React Engine

  • Abandoned project
    The repository appears to be no longer actively maintained, with no recent commits or updates. This makes it risky to use in production as bugs and security vulnerabilities may go unpatched.
  • Outdated dependencies
    React Engine was built for older versions of React and React Router. It may not be compatible with modern versions of React (16+, 17, 18) or React Router (v5, v6), limiting its usefulness in current projects.
  • Limited ecosystem support
    The library is tightly coupled to Express.js, meaning it cannot be easily used with other Node.js frameworks like Koa, Hapi, or Fastify, reducing its flexibility.
  • Better modern alternatives
    Modern tools like Next.js, Remix, and Vite with SSR plugins provide far more comprehensive and well-maintained solutions for server-side rendering with React, making React Engine largely obsolete.
  • Limited documentation and community
    The project has relatively sparse documentation and a small community, making it difficult for new developers to troubleshoot issues or find examples and best practices for advanced use cases.

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 React Engine

Overall verdict

  • Unable to verify a project specifically named 'React Engine' on GitHub with confidence, as this does not correspond to a widely recognized or well-documented open-source project that I have reliable information about. There may be multiple small or niche repositories using this name, and quality would vary significantly between them.

Why this product is good

  • React Engine is not a commonly recognized name in the mainstream React ecosystem
  • No verifiable consensus data on stars, maintenance status, documentation quality, or community adoption is available
  • Could refer to a personal project, a boilerplate, a rendering engine, or a niche tool - without more context, its quality cannot be assessed
  • Names like this are sometimes used for student projects, abandoned repos, or experimental tools that lack production readiness

Recommended for

  • Not recommended without further verification
  • Developers should search GitHub directly, check star count, last commit date, open issues, and documentation before adopting
  • Best suited for evaluation on a case-by-case basis rather than a blanket recommendation
  • If you have a specific repository URL, sharing it would allow for a more accurate assessment

Questions & Answers

As answered by people managing speaking.app and React Engine.

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.
