Your whole photo workflow, in one quiet, native app.

Marlin is a pro photo library, RAW develop studio, and AI enhancer in one — with AI that's optional, runs locally by default, and never spends a cent without asking.

Everything, end to end

From a thousand frames to the one — without leaving the app.

A calm, content-first interface that gets out of the way. Neutral dark gray chrome so nothing biases how you see your photo.

Cull at the speed of thought

Rate, flag, and reject with a keystroke. Compare two frames side by side and keep only the keepers.

  • Star ratings & pick/reject flags
  • Side-by-side compare & survey
  • Multi-select, batch & sync settings

Develop with precision

A live histogram, full tonal control, white balance, presence, detail — plus crop, straighten and lens corrections.

  • Numeric value beside every slider
  • Before / after, split & loupe
  • Crop guides, optics & vignette

AI Enhance, honestly

Upscale, denoise, sharpen and recover faces with installed models. A real progress bar — never a frozen window.

  • 2× / 4× / custom upscaling
  • Pick the exact model per task
  • Split before/after preview

An assistant that proposes

Describe an edit in plain language or ask for a critique. Every suggestion is a card you review and approve — never a silent change.

  • Conversational, reviewable edits
  • Auto-tag & cull suggestions
  • Completely optional
Cost safety, built in

Money is never spent by accident.

Marlin defaults to free, on-device processing. The active backend is always visible while you edit, and the first time a photo would ever touch a paid cloud, Marlin stops and asks — with the estimated cost up front.

  • Free local backend is the default on every launch
  • One-time confirmation before any paid send
  • A running session cost counter, always in view
FREE · LOCAL

On this Mac

Private, unlimited, no bill — the default.

How the AI works

Local by default. Optional always. Yours entirely.

Run models on this Mac, on another machine on your network, or in the cloud — your call. Marlin works completely without any AI connected.

01

Choose your backend

Local on this Mac (recommended & free), a remote machine on your network, or a cloud provider with your own key.

02

Manage your models

Install, enable and discover the latest photo & restoration models — nothing downloads without an explicit click.

03

Stay in control

The assistant only ever proposes. You see exactly what changes, preview it, and apply or reject.
