Ask HN: What simple web apps do you wish existed? Seeking ideas for sample apps

45 pointsby zainhodaabout 2 years ago
Hello!<p>I&#x27;m looking for ideas for simple web apps that people wish existed. I plan to select some of those ideas and implement a “v0” or prototype version of the idea using PyCob, a Python project that makes it easy to create web apps using just Python. The easiest types of apps to implement would be Python libraries that you wish there were a front-end for. I’ll post the demo and code here: https:&#x2F;&#x2F;www.pycob.com&#x2F;<p>If you have an idea for a simple web app that you think would be useful or fun, please share it in the comments below. These are some examples of demo apps we’ve made:<p>PyPi Analytics: Show trends of how many downloads PyPi packages have over time<p>HN Analytics: Find the best time to post on Hacker News<p>Dataframe Explorer: Choose fields from a dataframe to pivot and graph the results<p>App Wizard: Generate Python code for a CRUD app<p>Book Summary: Choose a book and get a 10 bullet point summary AI Regex Generator: Give the app 3 examples and have AI (try to) generate a regex pattern<p>Warranty Claims: Allow users to submit warranty claims and track status of replacement parts<p>These are just a few examples – feel free to suggest any kind of app you can think of!<p>Thanks in advance for your ideas. I&#x27;m excited to see the ideas, and I look forward to implementing some of these apps using PyCob.<p>Thanks!

An interface to preferentially compare and choose between 2 objects, using a Tinder like interface (swipe left&#x2F;right mechanics). Every year I do a stack ranking of baseball players for my fantasy league. If I had this interface, I could easily setup an ELO comparison function to create my complete list out of a series of easier comparisons.<p>I have at times also wished I had this for just about any sort of data tagging. Give it an array of json objects, it displays the data and then lets you swipe super quickly through all the objects in the array, semi-randomly choosing which objects to compare. Would need to write the data out as well - that&#x27;s the product.<p>This is probably worth a couple hundred bucks to me if anyone wants to build it and open source under a commercial-reuse allowed license. Every year I spend dozens of hours doing this and don&#x27;t feel like I have done a great job of making the correct comparisons.

Here&#x27;s a thing I always wanted: Show big Twitter discussion with loads of subthreads&#x2F;replies in Reddit&#x2F;HN &quot;comment tree&quot; format.

I am working on something similar to a dataframe explorer called data cleaning framework. Would love to talk to some people about it. The idea is that everytime I start data analysis with pandas, I run through the same adhoc data cleaning commands in many configurations. I&#x27;m building a graphical UI that lets you quickly try different commands AND it outputs python code to accomplish the same transforms.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;paddymul&#x2F;dcf-server">https:&#x2F;&#x2F;github.com&#x2F;paddymul&#x2F;dcf-server</a>

Youtube channel or playlist to RSS feed, that I can then add to my podcast player. The link should point to the audio version of the youtube video.<p>There is already one out there that I use, but its very badly designed.

I have two that I&#x27;ve been thinking about that I&#x27;ve been too lazy to cobble together myself:<p>A page change tracker that A: pumps the page through uBlock origin before each snapshot and B; produces an RSS feed with a summary of changes.<p>A web page to epub converter that A: sends the page through uBlock origin or similar, B: sends the result through the postlight parser, and then C: gives the user a chance to customize the result before packaging it up as an epub. Customisation would include setting a cover image (or none,) setting a title and other metadata, choosing to include a TOC or not, renaming any chapters if a TOC is included, etc. Currently my workflow for this involves someone&#x27;s &quot;web page to epub&quot; converter personal project that isn&#x27;t entirely designed for single pages and a bunch of time on Sigil cleaning up the resulting output.

I&#x27;ve always wanted to build an &quot;I told you so&quot; webapp.<p>Something that would store phrases associated with people with an incremental counter. Obviously the list of phrases, people, and counts are unique to the user.<p>This way I can say to my daughter, &quot;I&#x27;ve told you &lt;checks webapp&gt; 46 times now to clean up your room!&quot;<p>Dumb, but fun :)

Voice activated calculator that allowed me to rapid fire simple math from across the room.<p>If it did math while people were meeting and conversing and spat out an answer, that would be pretty cool.<p>I also like counting apps: take a picture of a bowl of Cheerios and it counts the &#x27;O&#x27;s, or the number of pipes in a rack at a hardware store.<p>I&#x27;m sure they&#x27;ve been engineered already or at least thought of before, but so far voice calculators seem slow and clunky like voice assistants, and counting apps lack surety and I wouldn&#x27;t bet anyone&#x27;s job on them that I&#x27;ve found so far.

Markdown articles to JSON and&#x2F;or JSON upload to websites.<p>That&#x27;s a soft JSON not a must-be JSON. I&#x27;d kill for an all markdown workflow where I could build content&#x2F;blog posts in my markdown app (Logseq) by selecting a layout template, writing the articles and selecting pictures, and then I could kick off a simple upload process to my web server.

Great Idea. I have a usecase where I have more than 15 API&#x27;s and several Postgres tables. I want to quickly create a Web UI with form for support teams to perform GET&#x2F;POST&#x2F;DELETE&#x2F;PATCH requests. And also show the table contents.<p>Web UI with a form + Table Exploration from Database would be great.

the pypi analytics one is cool. what about doing something similar for github analytics? i find it more interesting and expansive than pypi.

Something with LLMs that uses sanitized data so it’s useful and not jailbroken and shut down within a month.<p>For example:<p>- an app that forecasts the weather where you are in 1 sentence.<p>- an app that summarises user reviews of points of interest around you.<p>- an app to summarise YouTube videos based on their transcripts.<p>- an app that describes your address in 1 sentence as you would to an emergency service (“26 miles West of Placename on E25” or “on the corner of Eve drive and Redmond Avenue”, or “at Trafalgar square”). Shown with a map with all used place names for confirmation.<p>- an alternative history daily news generator with several settings (cyberpunk, soviets won space race, world peace, world war 3, Nazis won WW2, the Earth is flat, brave new world, etc).<p>- an endless text based adventure game where AI gives you some story and a verb each turn. You can set a theme in the beginning in 40 characters.<p>- an app to transcribe and summarize voice recordings, for lectures and journaling (should be sanitized for jailbreak instructions but would be a useful app).<p>- an API or app to generate long memorable pass phrases (based on semi random context like a random Wikipedia page).
