3. Show HN: I created a to-do app that lets you submit tasks as quickly as possible
URL: https://apps.apple.com/de/app/doday-daily-focus-to-do/id6473123694
Author: yassiniz
Description: Hello HN!
I’ve had this idea for a long time and created this app out of frustration with other to-do apps.
It feels like you’re filling a job application form just to add a task. Additionally, I’ve always worked better by creating to-do lists scoped to a day, which is also a main feature here.
I created the whole app with SwiftUI and SwiftData - This is in fact my first mobile app with a native stack, and I must say, I absolutely love how easy this stack feels compared to my usual JS stack nowadays.
I’m also giving away the lifetime pro version for just $9.99 until end of October - most of the features are free however, and I made it an important point not to track users :)
I’d love to get some feedback as well!

10. Show HN: Open-Source Zero-Shot Image Model Server Enabling Model Feedback
URL: https://github.com/DirectAI/simple-data-free-model-server
Author: isaacrob
Description: Hi everyone!
Here is an open source implementation of a decently performant server hosting zero-shot image models (CLIP for image classification, OWL-ViT-ST for object detection), with an extra algorithm to allow users to give the models feedback when they make mistakes! We built a company off this flavor of tech two years ago and have clients who are currently using our commercial API. We are now moving on to other projects but want to make sure our clients still have access to the approaches that they’ve grown to rely on, so we’re open sourcing a simple implementation that they’ll be able to use after we’ve shut down our hosted API!
I used to work at a robotics startup. After a while it seemed clear that the biggest limiting factor in our ability to ship new models wasn’t innovation on model architecture, it was access to relevant, high-quality training data. Around that time CLIP was released, which got me thinking about the idea of having models with world-knowledge baked in so as to reduce the amount of training data required. A year later when Stable Diffusion dropped, my cofounder Ben Brooks and I took the plunge and founded DirectAI, where we worked on building ways to get performant models without collecting any training data, using the knowledge stored in pretrained models instead.
In this implementation, we replace the linear classification head typically used in zero-shot image classifiers with a modified nearest neighbors method that lets you use multiple examples (both positive and negative) per-class to make sure the decision boundary the model is using is more aligned with what you had in mind.
Our clients have found it very useful for things from interior design to content moderation to sports analytics, building models that are either too niche to be supported by a traditional cloud-hosted computer vision API or are subtly different from the models that existing cloud APIs host. For example, one of our clients wants to filter out all images containing alcohol. Hive has an API for that, but Hive explicitly allows red solo cups that don’t obviously have anything alcoholic in them, whereas our client wanted to filter those out too!
Feedback is welcome! There are still bugs in the Gradio frontend / codebase in general, but I have a deadline and need to be working on new stuff at a new job starting Monday so I thought I would just go ahead and get it out there! I’ve never tried to publish a real open source piece of code before and I must admit I am quite nervous!

14. Show HN: Tolgee – developer-friendly localization tool
URL: https://github.com/tolgee/tolgee-platform
Author: jancizmar
Description: Software localization has been broken for years. That’s why I created Tolgee.
Eight years ago, I worked in a company that was developing a not-so-small system for lawyers. And it was extremely painful for me as a developer to handle the localization of the app.
The process looked like this:
1. Add many keys to the code like “transport_form_name_input_label,” “transport_form_car_input_label,” etc.
2. Run some extractor to extract the keys from the code.
3. Open the target language data file in an app called Poeditor
4. Import the extracted keys.
5. Find and translate the new values - This was super painful since there were many untranslated keys, and it was hard to find the new ones.
6. Repeat from step 3 - we were translating to 2 versions of the Czech language because of different customer types.
The most common bug was forgetting some key untranslated because developers always kept this as the last part of the feature task.
Later on, we started to think about how to improve this process so the localization doesn’t rely on developers.
However, we found out that designers, project managers, and product managers cannot work with Git, and it’s also hard for them to find out which keys are rendered where in the system.
It was impossible to simply transfer the task to those.
So my idea was to enable them to simply click on the strings in the actual translated app, give them simple dialog, and let them translate it exactly in the place where it’s rendered.
Four years later, I got to implement this idea as a part of my master’s thesis, and later on, I founded Tolgee.
You can quickly deploy Tolgee app with Docker / Docker compose.
It’s fully open-source (Apache-2), we only have one enterprise folder on a different license.

18. Show HN: I gamified coworker recognition using a reward system
Author: solorami
Description: Hello everyone!
As a remote software engineer, I often felt disconnected and unrecognized. After talking with colleagues who felt the same, I built a tool to change that. It uses gamification—team members can give recognition, earn points, and collect badges. Leaders can send surveys for feedback, and everyone gets Slack notifications for recognition and surveys.
Similar to how language learning apps like Duolingo and Memrise make studying fun by tapping into the brain’s reward system, this tool brings that same concept to the workplace. Instead of the old, boring ways of recognizing co-workers, we added a game-like experience, focusing on making recognition more engaging and rewarding.
I hope this helps others feel more connected and appreciated. I’d love to hear your feedback!

19. Show HN: Never Launch Without a Waitlist
Author: ilpr
Description: Hey!
I’ve recently launched Waitlister, an app for creating product launch waitlist in minutes (or seconds if you wish to).
Why you should build a waitlist before you launch your product? Because,
- it’ll help you validate your idea before spending too much time on building,
- get first users that will potentially convert/sign up as soon as you launch,
- and you can generate more buzz for your launch than you could without one.
How does Waitlister help you with this? With it, you can:
- create a hosted landing page,
- create an embeddable waitlist form,
- send automatic welcome emails,
- send email broadcasts to keep subscribers engaged/updated,
- incentivize virality with referrals,
- and more…
Hope you’ll find it useful.

27. Show HN: I made an affordable email verification service
Author: dorukce
Description: Hi HN!
I wanted to share a project I’ve been working on for a while.
As a developer, I’ve experienced the frustration of seeing email campaigns land in spam folders or bounce back due to outdated or invalid email addresses. Email still is a powerful outreach medium, and we shouldn’t have the fear of getting blacklisted. Instead, we should focus on writing that great email.
That’s why I’ve created Heybounce. It is a fast and affordable email verification service with an API for developers and a no-code tool for list uploading and cleaning.
It blocks fake signups (disposable emails). Removes inactive and invalid email addresses. Cleans spam-traps and honeypots.
If you have any questions about the product or any feedback, feel free to write them below, and I’ll be more than happy to answer them.

28. Show HN: Hacker News Book Recommendations
URL: https://hackernewsbookrecommendations.com/
Author: mjcurl
Description: After reading this Ask HN post [1] (and buying too many books), I found myself going through old posts about book recommendations. I wanted to find all books recommended in those posts and save the top ones for future book shopping sprees. This has been done before [2, 3], but I wanted to get books that were recommended, not just mentioned.
I used the Algolia API [4] to get all Ask HN posts about books, reviewed them and filtered out ones that were too specific e.g best books to learn math. The comments were then sent to the Open AI API [5] to extract books that are recommended.
I then grouped them, but books can be mentioned with different names (Godel, Gödel, GEB?), and GPT4 wasn’t doing a good job finding similar titles in a long list (25k titles). So that part had to be done mostly manually.
Finally, I added a page to browse by posts, some stats (like users who recommended the most books), and highlighted mentioned books in the comments.
I hope you find a good book! Feedback is welcome :)

29. Show HN: Co-Op Translator: Automate Markdown and Image Translations with Azure
URL: https://github.com/Azure/co-op-translator
Author: skytin1004
Description: I’d like to share Co-op Translator, a tool I’ve been working on to automate the translation of project documentation.
It uses Azure OpenAI for text translation and Azure Computer Vision for extracting text from images, allowing developers to quickly translate Markdown files and images into multiple languages with minimal manual effort.
Why Co-op Translator? It automates the tedious process of translating project docs while keeping Markdown formatting intact. Supports both Markdown and image translations. Great for internationalization and localization of open-source projects.
I’m looking for feedback from the community on how to improve the tool or any additional features that could be useful.
