Bleach bypass
- “fuji 400h, lifted shadows, warm highlights”
- “cool cinematic, crushed blacks, blue-grey palette”
- “modern blockbuster orange and teal split tone”
- “desaturated, high contrast, silver retention”
Features
A small set of tools, used hard.
Everything Asterik does is in service of one idea: take any photo, give it a great color grade, fast — without an editor full of sliders.
Describe in words
Type a phrase like “moody bleach bypass with crushed blacks” and Asterik translates it into a structured grade — temperature, contrast, split-tone, grain, vignette — and applies it deterministically.
Or copy a reference
Paste up to four reference photos. Asterik analyses their color, tone and grain only, blends them, and applies that look to your photo. Content is preserved exactly.
Two engines, one toggle
A bold direct-edit engine and a gentler deterministic LUT engine. Switch between them on the fly to compare looks before you commit.
Community catalog
Browse looks painted by other photographers, like the ones that work, save the ones you love. A time-decayed ranking surfaces the filters people are actually using right now.
Your photos stay yours
Source images are stored privately in signed buckets. Filters you save are private by default — publish them to the catalog only when you choose to.

FAQ
Things people ask.
What does Asterik actually do?
Asterik is an AI photo color-grading tool. You give it a photo plus a description ("warm Fuji 400h", "orange and teal cinema") or a reference image, and it returns the same photo with that look applied. It only changes color, tone and grain — never the subjects, faces or composition.
How is this different from Lightroom or VSCO presets?
A traditional preset is a fixed slider configuration. Asterik generates a fresh grade for each prompt or reference, then applies it deterministically to your photo. You don't need to learn what 'whites +12, blue luminance −8' means — just describe the result you want.
Will it change my photo's content?
No. The AI is constrained to color, contrast, saturation, temperature, split-tone and grain only. Faces, composition, objects and details remain untouched. The deterministic LUT engine in particular guarantees a content-preserving transform mathematically.
Can I use Asterik on my phone?
Yes — Asterik is mobile-first. It runs as a Progressive Web App, so you can use it from any phone browser without installing anything, and add it to your home screen if you want an app-like experience.
What's the difference between the two engines?
Bold (direct edit) sends your image to a vision model that re-paints it in one shot — striking, commits hard, occasionally drifts. Gentle (hybrid LUT) extracts numerical grading parameters and applies them deterministically with Pillow + NumPy — content-perfect, faster, cheaper, and reproducible.
What can I do with reference images?
Paste up to four photos as inspiration. Asterik analyses their color, tone and grain only, blends the looks together if you provide multiple, and applies the result to your source. Useful when you can't put a look into words but you know it when you see it.
Are my photos private?
Yes. Source images are stored in private signed buckets, not on a public CDN. Filters you save are private by default. You only publish a filter to the catalog if you explicitly choose to.
How does the catalog work?
Pro users can publish filters to a community catalog. Other users can apply, like and save them. A time-decayed ranking surfaces filters with recent traction so the catalog stays fresh rather than fossilising on early hits.
Can I cancel my Pro subscription?
Yes, in one click from inside the app. Pro is billed monthly via Stripe. Cancelling stops future charges and keeps your account on the free plan with all your saved filters intact.
Do exports include a watermark?
Free plan exports include a small "ASTERIK" signature in the corner. Pro users can toggle the watermark on or off per generation.
