Numbers you can act on
Every output is concrete: a bitrate, a LUFS, a panel count, a hashtag density score. Nothing that says "consider optimizing". If we cannot turn it into a number, we don't ship the tool.
Built for creators who measure retention, not vanity likes
A working studio in your browser. Hook scoring, aspect-ratio safe zones, LUFS targets, retention curves, hashtag audits, posting cadence math — everything that actually moves the needle on TikTok, Reels and Shorts. No login, no upsell, no popup ads.
The web is full of generic calculators that solve fake problems. These were designed around the bottlenecks that consistently show up in short-form analytics dashboards — the ones where a small change (3 more frames, 2 dB louder, 12% smaller safe zone) can shift retention by a meaningful amount.
Every output is concrete: a bitrate, a LUFS, a panel count, a hashtag density score. Nothing that says "consider optimizing". If we cannot turn it into a number, we don't ship the tool.
No auto-playing video, no cookie wall, no "you've been selected". No fake download buttons. Just static HTML and Tailwind CSS. Mobile-first and screen-reader friendly.
Every tool lists what it cannot do. A hashtag checker can't predict virality. A retention predictor can't read your audience. We tell you, not pretend.
Five pages, grouped by where they belong in your workflow.
Tools you run before you record. Hook scoring, pace, storyboard panels, B-roll lists, intro drop-off.
Decisions in front of the camera. Aspect ratio safe zones, lighting, angles, green screen, color.
In the timeline. Frame rate, loudness, BPM sync, ducking, captions, contrast, watermarks.
Get out of the editor and onto the platform correctly. File size, bitrate, presets, repurposing, thumbnail legibility.
Post-publish thinking: hashtag audit, title frameworks, description templates, CTA scoring, upload timing, retention prediction, frequency.
If you already post consistently and want a quiet, dependable place to sanity-check your next cut, this is for you.
Saving you time up front so you do not have to learn the hard way.
Tools here run locally in your browser. They are deterministic and offline-friendly, but that means a few things they cannot do. Knowing this up front keeps your expectations aligned.
No real-time TikTok or YouTube API. Recommendations are based on documented platform guidelines and durable patterns.
Nothing is uploaded to a server. Calculations happen in your tab, on your machine.
A hashtag score of 95/100 still depends on platform algorithm, timing and audience fit.
Tools optimise structure. Story still comes from you.
