PolyPal

Timekettle · Writing

PolyPal is an AI live translation and subtitling app built by Timekettle that turns meetings, lectures, and live streams into something you can follow in your own language. It listens as people speak, then shows translated subtitles with recording-level latency. The app covers 43 languages and roughly 95 accents, handles both face-to-face conversations and online calls on Zoom, Teams, or Skype, and wraps everything up with AI meeting notes. On top of that, it translates audio, images, videos, and phone calls in the same place. It fits anyone who works, studies, or watches across a language barrier.

Simply Piano XR

Simply (formerly JoyTunes) · Writing · Voice & Language

Simply Piano XR is a piano learning experience from Simply (formerly JoyTunes) that mixes the company's AI-driven lesson platform with mixed reality on compatible headsets. You play a real keyboard. The app listens to your notes, scores your timing and pitch, and nudges you toward the next skill. The same engine already powers Simply Piano on phones and tablets, so XR is less a separate app than a new way to step into lessons you'd otherwise run on a small screen. As an AI piano learning app, it suits anyone who wants structured practice without a private tutor. You'll still need a real piano or keyboard to make it work. No keyboard, no lessons.

HeyHelp

HeyHelp · Writing · Marketing

HeyHelp is an AI email assistant that lives inside Gmail and handles the busywork of staying on top of your inbox. It sorts incoming mail into clear labels, drafts replies in your voice, tracks follow-ups, and turns email threads into calendar events. The goal is simple: cut the hour many people lose each day to email triage and give it back to them.

Bookshelf

Bookshelf · Writing · Business

Bookshelf is an AI book summary service that condenses more than 10,000 non-fiction titles into short reads you can finish in about 15 minutes. Each summary ships as text, an audiobook, and a downloadable PDF or EPUB, so you can absorb a business or self-help book on a commute, at the gym, or between meetings. It suits readers who want the core ideas of a book without committing to the full 300-page version. Simple idea. Big time saver.

Abook

Abook · Writing

Abook is a book summary platform that condenses more than 10,000 non-fiction titles into short, readable summaries you can finish in about 15 minutes. It pairs each book summary with audio narrations, downloadable PDF and EPUB files, and podcast-style discussions, so you can pick the format that fits your commute, your desk, or your evening. If you want the core ideas from popular business, psychology, and self-help books without committing to hundreds of pages, Abook is built for that. It's fast. It's focused.

Glarity Summary

Felo Inc. · Writing

Glarity is a browser extension from Felo Inc. that reads pages, videos, and documents for you and returns a short digest. Point it at a YouTube lecture, a Google result page, a PDF report, or any article, and it produces a summary, key moments, or a Q&A box in the sidebar. It also translates as you browse, using either machine engines or a large language model. More than 100,000 people use it. The core extension is free, and paid tiers start at $7.49 a month.

Fliki

Nine Thirty Five LLC · Writing · Video

Fliki is an AI video generator and text-to-speech platform that turns written content into finished videos. You paste a script, a blog link, a slide deck, or a one-line idea, and it writes the narration, picks visuals, adds music and subtitles, and renders a publish-ready clip. It runs in a browser, and paid plans lift the free tier's watermark and one-minute export cap.

Explainpaper

Explainpaper (EP Vibes) · Writing

Explainpaper is an AI research paper reader that explains dense academic text on demand. You upload a PDF, highlight the sentence that lost you, and the tool rewrites it in plain language in the same context as the rest of the paper. It arrived right as large language models became good enough to summarize technical prose without mangling the math, and it found an audience fast: the company says more than 400,000 researchers use it. The pitch is narrow on purpose. This isn't a citation manager or a writing assistant. It reads with you and answers the questions you'd otherwise have to bother a colleague about. So what does this paper explainer tool actually replace? Not your reference manager, and not your note-taking app. It sits between you and a PDF you can't finish.

Easy-Peasy.AI

Easy-Peasy.AI Pte. Ltd. · Writing

Easy-Peasy.AI is an all-in-one AI content platform that bundles an AI writing assistant, image and video generation, text-to-speech, transcription, and a no-code chatbot builder under a single subscription. It's built for marketers, small teams, and solo creators who want several AI tools without juggling separate accounts, and it starts free with a daily allowance of words and image credits.

DeepL Translate

DeepL SE · Writing

DeepL Translate is an AI-powered translation service from Germany's DeepL SE that turns text, documents, and images into more than 30 languages using its own neural network models. As an AI translation tool, it's known less for adding features than for output quality, and that reputation has carried it to adoption by over 200,000 businesses, including a large share of the Fortune 500. If you write across languages for work, school, or international clients, the tool targets that exact job. Simple as that.

Cohesive

Unacademy Inc. · Writing · Productivity

Cohesive is a browser-based AI content editor from Unacademy Inc. that combines a writing canvas, 200+ fill-in-the-blank templates, an AI image generator, and AI voiceovers in one workspace. It's built for marketers, freelance writers, and small teams who want a finished blog post, ad, or script without juggling five subscriptions. Unlimited words come free. Paid tiers start at $25 per editor per month.

ChatGPT Writer

Devcraft Studio · Writing

ChatGPT Writer is an AI writing assistant that runs as a browser extension and drafts emails, messages, and replies inside the sites where you already type. Think of it as an AI email writer that lives in your inbox. It's now branded Jetwriter AI, after a September 2025 rebrand, but the product underneath is the same tool that put ChatGPT into Gmail back in 2022. It works on Gmail, LinkedIn, Outlook, Slack, and most editable text boxes, and it's powered by a mix of GPT-5, Claude, and Gemini models rather than a single AI.
