The Take

The neat trick here is portability and privacy: it’s a single HTML file that runs entirely in your browser so photos never leave your device — a practical counterpoint to $15–30/mo SaaS. The feature set is pragmatic (9-photo grid preview, multiple collage layouts, 60+ hand-written captions, 3-tier hashtag sets, font styler and engagement benchmarks) and the UI reads like someone cared about UX, but none of the individual tools are groundbreaking — the value is in packaging and zero friction.

Post Description

Hey HN! I built InStudio — a free, browser-based toolkit for Instagram creators.

Everything runs locally (no server, no account, photos never leave your device). It's a single HTML file with vanilla JS.

10 tools included: - Grid Preview Planner (upload 9 photos, see your profile grid before posting) - Collage Maker (6 layouts, adjustable gaps, instant JPG download) - Caption Generator (60+ hand-written captions across 10 moods) - Hashtag Strategy Builder (3-tier breakdown: Mega/Medium/Niche tags) - Engagement Rate Calculator (benchmarks + personalized tips) - Bio Generator (5 styles instantly) - Font Styler (12 Unicode fonts that work in Instagram) - Color Palette Library (12 curated palettes with click-to-copy hex codes) - Best Time to Post guide - Aspect Ratio reference (every official Instagram format)

I built this because Instagram tools cost $15-30/month for features most creators only use 20% of. Figured there should be a free option that does everything in one place.

Tech stack is deliberately simple — 100% client-side, zero dependencies, works offline after first load. The whole thing is ~120KB.

Would love feedback from HN — especially on what tool I should add next, or if you'd pay for any features (trying to figure out monetization).

Revvly – Income operating system for freelancers (replacing 5 tools)

Smart product-market focus: bundling a LinkedIn AI assistant with an aggregated income dashboard and simple creator tools is sensible for people tired of paying for five disjoint apps. The landing page sells the value clearly ($39 vs $109/mo) and calls out concrete integrations (Stripe, PayPal, Upwork) and Claude for comment generation. I’m left wanting proof of depth — are the syncs two-way, how reliable are payouts mapping and tax estimates — but the MVP positioning and waitlist feel like the right next step.

Preview CoreML video models on any video feed

You can grab a CoreML model from Hugging Face and see inference applied to a live camera feed in realtime while stacking cinematic effects, firing one-shot triggers from MIDI, and streaming out via a virtual camera or RTMP. The combo of local CoreML preview + unlimited sources and CSS-overlay widgets is a clever, practical playground for both creators and researchers — the real test will be model compatibility and performance across consumer Macs.

Image to Photo

It turns illustrations, sketches and AI art into photo-like images in seconds and even bundles usage with a credit system and a commercial license — useful for people who need fast mockups or product shots. The downside: this lives in a crowded space with established img2img and restoration tools, and the site gives little transparency about which models are used, privacy or quality guarantees (5MB limit, credits), so it’s hard to tell if it actually beats the alternatives.
