Anki Tool

A Chrome extension for making Anki cards from anything you read.

I built it to study for the MCAT. 15K+ people have installed it since, and 5K+ use it every month.

It’s plain JavaScript, HTML and CSS on Chrome’s extension APIs, and it talks to Anki on your computer through AnkiConnect.

Get it on the Chrome Web Store Watch the demo

Anki Tool’s side panel beside Wikipedia’s Insulin article, with a card filled in from the page

Select a line on any site and send it to the front or back of a card. Here it’s Wikipedia’s article on insulin.
Deck, note type, front, back and tags sit in a side panel, so you never leave the page.
Wrap a word in a cloze deletion and the sentence becomes a fill-in-the-blank card.
Preview it the way Anki will show it, then add it to your deck.

GumHop

Type a task the way you’d say it. Finish it and you pull a card.

I wanted adding a task to take one sentence, and finishing one to feel like a small win. The boards, the team spaces and the API are there so that idea holds up for real work.

It’s Next.js and TypeScript with Supabase underneath. The parser sends your sentence to DeepSeek through the OpenAI SDK.

A parsed task on the GumHop board: a clean title, due tomorrow at 2:00 PM, with a phone number pulled out as a detail

The same parsed task on GumHop’s phone layout

A Legendary card, gold frame and all, pulled on GumHop’s phone layout

No form to fill in. The deadline and how urgent it is go in the same sentence.
The sentence comes back as a real task with a clean title, a day and time, and the phone number pulled out. Undo is one click away.
It might be Common, Shiny, Holographic or, on a lucky pull, Legendary.
Every pull lands in your collection, rarest first, with packs to finish and a day streak to keep.
Invite your team to a space, or give an AI agent an API key to add and finish tasks.
Type a task over whatever you’re reading, here one of my PrimerMed pages, and check one off to pull a card right there.

PrimerMed

A medical knowledge base for med school pregame, rapid review and clinical ramp-up.

It has 80+ topics, 50+ scribe guides and 10 categories, from foundational science to the surgical specialties.

It’s built with Astro, with every topic written in MDX. Search runs in the browser with MiniSearch, so results show up as you type.

PrimerMed’s vascular surgery scribe guide, open at its sample HPI templates

Search covers every topic and scribe guide. Pick a result and you land right on it, here peripheral arterial disease.
Highlight any term and the study menu can define it, explain it more simply or search the whole library for it.
The foundations have them, here the bones and ligaments of the hip.
This vascular surgery guide, with its sample HPI templates, is the one closest to my own work.

qpkit

It handles images, PDFs, audio, video, captions and more, plus a Theme Gallery of 95 UI styles.

I count it as 26 projects in one. It can tune a cello, transcribe a meeting, review a chess game and read the text off a scanned page.

It’s plain HTML and JavaScript with no build step and no framework. The heavy parts, like Whisper, Stockfish and background removal, run on your own device.

Jireader

Stories that teach Korean, one level at a time.

It has 400+ stories across TOPIK levels 1 to 5, and complete beginners start with a Hangul primer.

It’s React and TypeScript, and your progress stays on your device until you sign in.

Jireader’s placement check: tap the Korean words you already know

A Jireader story on a phone, with the narrated sentence lit and English under each line

A Jireader comprehension question answered correctly on a phone

Tap the Korean words you already know and Jireader starts you at the right level.
Each sentence lights up as it’s read aloud, English sits under every line, and a tap on any word opens its meaning.
You answer vocabulary and comprehension questions with a tap.
Spaced repetition brings each word back with the sentence it came from.

vid3k

Teams use it to make short-form video ads.

Import a viral reference post, see why it worked, then remake it for your own brand as a Hook + Demo, Text on Screen or Photo ad. It’s invite-only.

It’s Next.js 16 and Tailwind 4 on Neon Postgres. A Python worker on Modal handles the video with yt-dlp, faster-whisper and FFmpeg, and AI models generate the images and clips.

GameHour

Games for a room full of friends, each on their own phone.

The host gets a four-letter room code, and friends type it in to join.

It’s React with PartyKit keeping every phone in the room in sync.
