Really appreciate the zero-ad and zero-signup approach. Tested the 8K export on Firefox, clean and instant. Bookmarked for my desk setup.

That dedicated sparkle role is rare and honestly kind of beautiful. Most teams treat micro-interactions as leftover polish rather than something worth assigning ownership to.

Extra details (happy to answer anything):

Implementation note: Everything is processed client-side in the browser (no image uploads). The main goal was to make the “posting order” foolproof for the 2×2 grid and keep the workflow fast: upload → choose layout → download → post in numbered order.

I built a small web tool to generate “tap the post” / “tap-to-reveal” image slices for X (Twitter): https://splitimage.im/x-image-splitter/

What it does: - Split a single image into templates optimized for X multi-image posts: - 2×2 (4 tiles) - 1×2 (2 strips) - 4×1 (4 vertical strips) - Names files in the correct upload order (e.g., top-left → top-right → bottom-left → bottom-right), so you don’t accidentally post the tiles in the wrong sequence - Runs 100% in your browser (no server uploads)

Why I made it: I kept seeing the “tap the post” pattern on X, where the timeline grid looks cropped/mysterious and the full image is revealed when you open the post. Existing tools either felt too generic (no posting order help) or required uploads. I wanted something quick, local, and harder to mess up.

What I’d love feedback on: - Does the output look correct on X across desktop/mobile for you? - Any edge cases where the crop/reveal doesn’t line up (image ratios, unusual source sizes)? - Feature requests: presets, better previews, bulk mode, or anything else you’d expect from a tool like this.

If you try it and it breaks or feels confusing anywhere, please tell me what you uploaded + which layout you selected (a screenshot of the X preview helps a lot).

I’m a developer who watches (and learns from) a lot of YouTube playlists — courses, tutorials, lectures, even music mixes. And I kept hitting the same friction: before starting a playlist, I just wanted one simple answer — “How long will this take?” YouTube doesn’t show total playlist duration upfront, so planning becomes guesswork.

So I built ytplaylistlength.one. It’s a small, focused tool: paste a playlist URL (or a video URL / playlist ID), click calculate, and you’ll get the total duration — plus the “real” watch time at different playback speeds (1.25x, 1.5x, 1.75x, 2x, or custom). You can also calculate only part of a playlist (e.g., videos 1–50 or 31–100), paste multiple links, and export the results to Excel if you want to plan or track things.

Two values mattered to me while building it: • Privacy first: I don’t store your URLs or track your viewing habits — inputs are processed and discarded. • Free + no signup: the core tool should stay accessible and frictionless.

If it’s useful, awesome — that’s the whole point. If you notice bugs or have feature ideas, I’d honestly love the feedback.

Why I Built This I had some gold jewelry sitting around and wanted to know what it was worth. Simple right? I searched for "gold calculator" and tried a few sites. Most of them looked outdated—like they hadn't been updated in years. Some had prices that were clearly stale. Others were just lead capture forms pretending to be calculators. I couldn't find a tool that just worked: enter weight pick karat see value. That's it. So I built one myself. GoldCalc is what I wanted: clean interface live prices no nonsense. I added a few features along the way—multiple languages different currencies a dealer discount slider—but the core is still simple. It's free. No ads. No signup required. If you find any bugs or have suggestions let me know. I'm always improving it.
