I need a Chrome-based extension that watches a live YouTube stream, lets the viewer draw a bounding box on the video, and—every frame—grabs the characters inside that box, turns them into clean digital text, then instantly runs multiplication or division on the values it finds. The computed result must appear as a subtle but readable overlay positioned on top of the running video, all inside 1 second end-to-end. Here is what has to happen under the hood: • Real-time OCR on the selected area ([login to view URL], [login to view URL], or a comparable in-browser engine are fine as long as they keep latency under the one-second cap). • Simple UI to let the viewer draw / adjust the capture region at any time while the stream is playing. • Parsing logic that recognises alphanumeric strings, extracts the relevant numbers, and performs the requested multiplication or division automatically. • Overlay rendering that updates continuously, stays synced with the video, and doesn’t interfere with YouTube controls. Use Canvas, WebGL or CSS layers—whatever gives smooth 60 fps updates. • A clean settings pane so the user can toggle the extension, switch between multiplication and division, and choose text/overlay styling. Future-proofing: I may want to support several capture regions later, so structuring the code to allow additional boxes (even if only one is active for now) will earn extra points. Acceptance criteria 1. Extraction-to-overlay round-trip consistently ≤ 1000 ms on an average i5/8 GB laptop in Chrome. 2. OCR accuracy ≥ 95 % on high-contrast digits/letters sized 14 px or larger. 3. No console errors, no impact on normal YouTube playback controls. 4. Packaged as a standard Chrome extension (manifest v3) plus concise setup/usage guide. Send me a short note on your proposed tech stack, any latency figures you’ve hit before, and an estimated timeline for a working prototype.

Thank you for outlining this highly technical and performance-sensitive project. I am confident I can engineer a Chrome Extension that meets your real-time requirements, integrates seamlessly with YouTube, and maintains a consistently low-latency processing loop under one second. Below is my proposed approach, technology stack, performance plan, and delivery timeline. ⸻ 1. Understanding of Requirements You need a Chrome Extension (Manifest V3) that can: • Monitor a live YouTube stream in real time • Allow the viewer to draw and adjust a bounding box directly on the video • Capture that region every frame and perform near real-time OCR • Extract and parse numbers from the recognized text • Automatically run multiplication or division • Display the computed result as a smooth, unobtrusive overlay at ~60 FPS • Achieve end-to-end latency ≤ 1000 ms • Maintain OCR accuracy ≥ 95% on readable text • Introduce no interference with YouTube’s default UI/controls You also want the architecture prepared for multiple capture regions in future versions. I fully understand the precision and performance expectations. ⸻

Hi I can build this Chrome extension for you and keep it simple, fast, and reliable. The goal will be to read numbers from a selected area of a live YouTube video, do the calculation, and show the result on the video almost instantly—without breaking playback or controls. I’ll make it easy for the user to draw and adjust a box on the video while it’s playing. The text inside that box will be read in real time, the numbers will be picked out automatically, and the extension will handle multiplication or division and display the result as a clean, readable overlay. There will also be a small settings panel so the user can turn the extension on or off, switch calculation modes, and adjust how the overlay looks. I’ll structure the code so it’s ready for future updates, like adding more capture boxes later on. I’ve worked with Chrome extensions, live video overlays, and OCR-based features, and I know how important speed and stability are for something like this. You’ll get a standard Chrome extension (Manifest V3), clean code, and a short guide showing how to set it up and use it. I’m happy to discuss the technical approach and timeline whenever you’re ready. Best regards, Deepak

Hi there! Does your project require handling live stream buffering issues within the extension to maintain OCR and overlay sync consistently? Regardless, this is definitely something that I feel confident delivering on, given my past experience. I would love to discuss your project further! Looking forward hearing from you.
