Ask HN: How to automate aesthetic photo cropping? (CV/AI)https://news.ycombinator.com/item?id=46583569Hi everyone,I am a backend developer currently engineering an in-house automation tool for a K-pop merchandise production company (photocards, postcards, etc.).I have built an MVP using Python (FastAPI) + Libvips + InsightFace to automate the process where designers previously had to manually crop thousands of high-resolution photos using Illustrator.While basic face detection and image quality preservation (CMYK conversion, etc.) are successful, I am hitting a bottleneck in automating the "Designer's Sense (Vibe/Aesthetics)."[Current Stack & Workflow]Tech Stack: Python 3.11, FastAPI, Libvips (Processing), InsightFace (Landmark Detection).Workflow: Bulk Upload $\rightarrow$ Landmark Extraction (InsightFace) $\rightarrow$ Auto-crop based on pre-defined ratios $\rightarrow$ Human-in-the-loop fine-tuning via Web UI.[The Challenges]Mechanical Logic vs. Aesthetic CropSimple centering logic fails to capture the "perfect shot" for K-pop idols who often have dynamic poses or varying camera angJan 12, 2026 3:10 AM

Show HN: Transform any photo into paper animations in secondshttps://paper-animator.net/Paper Animator: turn any photo into a paper cut-out animation in seconds## What Paper Animator isPaper Animator is a browser-based tool that transforms any image or text into animated paper cut-outs, folds, tears, and “ransom note” style graphics, with no install or plugins required. It targets short-form video creators, marketers, and designers who want a distinctive paper/stop-motion look without learning motion graphics software.[1]## Why build this- Most “paper” or stop-motion looks today require After Effects, templates, or manual masking, which is overkill for TikTok/Reels/Shorts creators who just want a quick effect.[1] - Existing mobile/video apps rarely combine AI background removal, realistic paper textures, and export-ready formats (green screen, transparent PNG sequences) in one place. - The goal is a “Canva for paper animation”: upload → tweak → export in under a minute.## How it works- Upload a photo (JPG/PNG/WebP up to 10MB); the AI removes the background and extracts thJan 10, 2026 5:28 PM

Show HN: Hazbin Hotel OC Maker – Create Original Characters with AIhttps://aiocmaker.com/oc-maker/hazbin-hotel-oc-makerHi HNI built a Hazbin Hotel OC Maker, an AI-powered tool that helps fans create original characters (OCs) inspired by the Hazbin Hotel universe.As a fan myself, I noticed that many creators struggle to turn vague ideas into a complete OC — especially when it comes to personality, backstory, visual traits, and tone consistency with the Hazbin Hotel style. Most tools focus only on images or only on text, so I wanted to combine both into a single workflow.What it doesGenerates original Hazbin Hotel–style characters (not existing canon characters)Helps define:Name & demon typePersonality traitsBackstory & motivationsVisual description suitable for artists or AI image toolsDesigned for writers, roleplayers, and artistsWorks entirely in the browser, no setup requiredWhy I made itI’m building a broader AI OC creation platform, and this is one of the first focused generators aimed at a specific fandom.

Show HN: I made a clipboard-triggered YouTube summarizer (no paste, 2 taps)https://apps.apple.com/us/app/esse-ai-video-summarizer/id6751778111How it works:Copy a YouTube link → open app → it auto-detects from clipboard, pulls metadata + transcript, and generates a structured summary (key points + narrative) in seconds. No inputs, no pasting, no prompting. Supports 60+ languages for summaries, the video's language doesn't matter.Why I built:I had an endless queue of educational videos but no time to sit through rambling or clickbait. ChatGPT flow = copy → open → paste → prompt → pray it formats correctly. Existing summarizers felt feature-bloated or unreliable. I wanted something super minimalist: “clipboard → value” on repeat.Decisions:Stack — React Native 0.81 (New Arch) + TypeScriptClipboard trick— Monitors clipboard on app start/resume — no manual pasteCaching— Stores transcripts + summaries in AsyncStorage with metadata— fast image library prevents repetitive refetchingAPIs— YouTube metadata— Third-party transcript provider (exploring Whisper)— OpenAI for summarizationOutput— Structured prompts → consistent format acrossOct 16, 2025 3:39 PM

Show HN: Vizzly – Visual testing platform with built-in review workflowshttps://vizzly.devHey HN! I’m Robert. I worked on [Percy’s SDKs/support from 2018–2022.](https://github.com/percy/cli/graphs/contributors) If you ever reached out to support or opened an issue, I probably helped you. Hopefully it was positive :) After a few years away, visual testing still felt stuck, so I'm building Vizzly.The problem: Design handoffs kinda suck. Designers make beautiful specs, devs implement them, then everyone realizes the details got lost somewhere. Current visual testing tools catch broken CSS but miss the real issue - making sure what ships actually matches what was designed, functionally (like really in the browser/OS/etc).What it is- Visual testing + review where you send actual screenshots (not DOM re-renders). Can be _any_ image to review (PDFS!)- Collaboration built-in: reviewer assignment, approvals, @mentions, screenshot-level threads.- Baselines: automatic (Git-aware), manual (not Git-based), or hybrid.- Team-based pricing; generous free plan for OSS; on-prem available.WhaSep 7, 2025 3:44 PM

Long term, I’ll add a single one-time unlock, not a subscription. This was my first big React Native project, I learned a lot about iCloud sync and native integrations along the way!*Features so far:*- iCloud backup (no external servers) - Daily highlights with a single image (on purpose) - Pin lock + biometrics - Custom prompts for entries - Morning & evening journaling - Mood tracker (syncs with Apple Health) - Weekly challenges & daily quotes (Stoic + others coming) - Reminders & timeline view*Would love feedback on:*- The UI/UX: does the minimalist approach work? - Features: what feels essential, missing, or over-complicated?App link: https://apps.apple.com/us/app/my-daily-journaSep 4, 2025 12:15 PM

Launch HN: Channel3 (YC S25) – A database of every product on the internethttps://news.ycombinator.com/item?id=44962881Hi HN — we’re George and Alex, building Channel3 (https://trychannel3.com/), a database of every product on the internet, searchable via text/image, and with built-in affiliate monetization. Here’s a demo: https://www.youtube.com/watch?v=Mx8FyP7KvJg.It’s surprisingly hard to find good product data. If you want your software to recommend products and deep-link to merchants, you’ll quickly discover that the data you need—clean titles, normalized attributes, deduped listings, current prices and inventory, variant options, images, and brand info—is not just messy; it’s also spread across a long, long tail of retailers, and often lives behind advanced bot-detection systems.We ran into this problem while building an AI teacher that could recommend relevant supplies. We asked Exa for products, but got back articles, not structured data. Same for Tavily and Bing (deprecated as of 8/13/25). And we got rejected from affiliate programs, who suggested we come back with 1000s of TikTok followers. CAug 20, 2025 3:34 PM

Show HN: Phofee – Photography social platform built with Svelte 5https://phofee.com/Hello everyone! For the past few months I have been working on Phofee, a social platform for sharing high quality photos.The goal: Make a website that allows users to easily upload, share, and discover photos without having to sacrifice quality or mangle their images.Phofee allows users to upload multiple images of varying aspect ratios. All sub images in a single post are displayed in a small photo gallery, so all your photos can be seen at a glance.One of Phofee's unique features is the automatic extraction of photo metadata. When a user uploads a photo, metadata such as Camera Model, Lens, Aperture, ISO, and shutter speed are displayed under your photo. This way, other photographers can gain better insight into your creation process and learn from it.For this project, I took privacy very seriously. - All metadata is deleted from user's photos before posting. - We store minimal user information. - We don't store user passwords (by using Google OAuth). - We don't use Google Analytics.Aug 18, 2025 1:18 PM

We only want human ratings, for obvious reasons.)Here’s a demo video: https://www.youtube.com/watch?v=vPyEQnuVgeIWe didn’t set out to build this - we were actually working on an AI game engine. But we found that models sucked at look-and-feel.
