Transcript-based video editor that runs 100% locally on Mac
Hi HN! I made ScriptEdit, a free Mac app that lets you edit videos by editing their transcripts. Everything runs locally on your machine. Think of Descript but free, local, and no long lags for video uploads or file / time limits. How it works: * You import videos, then ScriptEdit generates a transcript using Whisper (you can choose model). * Then you edit the text and the video cuts automatically match your edits. * Delete words to remove sections, rearrange sentences to reorder clips. * You can 'delete all filler words' or 'delete all gaps' to get much more professional videos without…
In plain words
ScriptEdit is a free Mac application that enables video editing through transcript editing. Users import videos, and the app generates transcripts using OpenAI's Whisper model, then automatically adjusts video cuts when users edit the text. Features include deleting words to remove sections, rearranging sentences to reorder clips, bulk removal of filler words or gaps, visual drag-and-drop editing, multi-track timeline support, and layer controls. Everything processes locally on the user's machine without upload delays or file limits, designed for creators who prefer transcript-based editing workflows.

Hi HN! I made ScriptEdit, a free Mac app that lets you edit videos by editing their transcripts. Everything runs locally on your machine. Think of Descript but free, local, and no long lags for video uploads or file / time limits. How it works: * You import videos, then ScriptEdit generates a transcript using Whisper (you can choose model). * Then you edit the text and the video cuts automatically match your edits. * Delete words to remove sections, rearrange sentences to reorder clips. * You can 'delete all filler words' or 'delete all gaps' to get much more professional videos without a lot of painstaking edits / cuts. * You can also drag / drop / cut visually. Features: * Native Mac app, optimized to use metal for faster transcription + rendering. * Multiple Whisper model options (tiny to large-v3) * Multi-track timeline support and layers / opacity * Title overlays and caption templates * Handles large files -no upload limits I built this because I wanted Descript-style editing without uploading my videos anywhere or paying based on video length or transcripts generated. I was also frustrated that tools like DaVinci Resolve, Captions, OpusClip, and Descript are all pretty expensive for what should just be a better way to edit videos locally. Useful if you have bandwidth limits, large files, or just prefer local tools and not paying through the nose every month. Happy to answer questions about the implementation or anything else.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
