How it works
- Resize input image to max 1024px (preserving aspect ratio) and save to disk
- Send the resized image to Claude Sonnet via the Files API; generate a short surrealist story and image prompt
- Pick a random visual style from the built-in style library (or specify one with
--style) - Pass the story + style + resized image to Gemini to generate the re-imagined version
- Save all run metadata to a local SQLite database (
~/.imagemine.db)
Requirements
- Python 3.14+
- An Anthropic API key
- A Google Gemini API key
Quick Start
uvx imagemine path/to/photo.jpg
The generated image is saved to the current directory. The terminal UI shows each pipeline step with live spinners, elapsed timers, and a final summary panel.
Installing
To use imagemine without invoking uvx, permanently install it as:
curl -LsSf uvx.sh/imagemine/install.sh | sh
imagemine path/to/photo.jpgAPI keys
Keys are resolved in this order on each run:
- Database — stored in
~/.imagemine.dbafter first entry - Environment variables —
ANTHROPIC_API_KEY,GEMINI_API_KEY - Interactive prompt — if neither is found, you are prompted (input is masked) and the value is saved to the database for future runs
To set keys via environment:
export ANTHROPIC_API_KEY=sk-ant-... export GEMINI_API_KEY=AI...
To set or update keys directly in the config database:

--input-album and --input-dir are mutually exclusive. When image_path or --from-run is provided, that explicit source takes precedence over configured INPUT_ALBUM and INPUT_DIR defaults. When picking from an album or a directory, photos that were never used on a previous run are preferred, so scheduled runs keep transforming fresh material.
Examples

Styles
Each run applies a randomly selected visual style from a built-in library of 35+ styles. The style name and description are appended to the image prompt sent to Gemini.
Example styles: Watercolor, 8-Bit Pixel Art, Ukiyo-e Woodblock, Neon Noir, Tarot Card, Vaporwave, Glitch Art, Renaissance Painting, and more.
Choosing styles interactively
imagemine photo.jpg --choose-style
Displays a numbered table of all styles. Enter one number (e.g. 3) to use that style, or a comma-separated list (e.g. 1,5,12) to blend the selected styles into a single prompt. Each selected style's usage count is incremented.
Using a custom style prompt
Use --style to pass a free-form style prompt directly instead of picking one at random from the database. imagemine will describe the photo, append the style text, and generate the image.
imagemine photo.jpg --style "Risograph print, grainy ink, limited overlapping spot colors"Listing styles
Prints a table of all styles in the database with their description and usage count.
Adding a style
Prompts for a name and a description/prompt, then saves the new style to the database. It will be included in random selection on future runs.
Removing a style
Displays a numbered table of all styles. Enter one or more numbers (e.g. 1 or 1,3,5), review the confirmation prompt, and confirm to delete.
Sharing style libraries
imagemine --export-styles styles.json imagemine --import-styles styles.json
--export-styles writes every style as a JSON list of {"name": ..., "description": ...} objects. --import-styles upserts each entry by name (existing usage counts are preserved), so you can back up your library or share it with others.
Character Mappings
When imagemine picks a photo from a macOS Photos album, it reads any face-detection names associated with the photo. Character mappings let you rename these before they reach the AI prompt — for example, mapping "John Smith" to "Captain America".
Adding a mapping
imagemine --add-character-mapping # Input name (from Photos): John Smith # Mapped name (for prompt): Captain America
Listing mappings
imagemine --list-character-mappings
Removing mappings
imagemine --remove-character-mapping
Displays a numbered list of mappings. Enter one or more numbers to remove, then confirm.
Configuration
Run the interactive config wizard to set or update any value:
The wizard walks through each key in order, pre-populates non-secret fields with their current values, and masks API key input. Leaving a field blank keeps the existing value (or skips it if unset).
| Key | Description |
|---|---|
ANTHROPIC_API_KEY |
Anthropic API key (checked before env var) |
GEMINI_API_KEY |
Google Gemini API key (checked before env var) |
DEFAULT_DESC_TEMP |
Default sampling temperature for description generation (e.g. 1.2) |
DEFAULT_IMG_TEMP |
Default sampling temperature for image generation (e.g. 0.8) |
CLAUDE_MODEL |
Claude model to use for description (default: claude-sonnet-4-6) |
GEMINI_MODEL |
Gemini model to use for image generation (default: gemini-3-pro-image-preview) |
INPUT_ALBUM |
macOS Photos album to pick a random input image from |
INPUT_DIR |
Directory to pick a random input image from |
DESTINATION_ALBUM |
macOS Photos album name to import generated images into |
ASPECT_RATIO |
Aspect ratio for generated images (default: 4:3); must be a ratio listed at the Gemini docs |
Cutting the description cost
The description step is a short creative-writing task, so a smaller Claude model works well. Set CLAUDE_MODEL to claude-haiku-4-5 (roughly a third of the per-token price of the default Sonnet model) to make scheduled runs cheaper:
CLAUDE_MODEL=claude-haiku-4-5 imagemine photo.jpg
Each run records the Claude token counts, and --history shows the estimated description cost per run.
Apple TV screensaver
You can use imagemine to generate a living screensaver on Apple TV by continuously transforming photos from one album and depositing the results into another.
Setup
-
In macOS Photos, create two albums — one for source photos (e.g.
Camera Roll) and one for the generated output (e.g.imagemine). Make the output album a Shared Album so Apple TV can see it. -
Configure imagemine to read from the source album and write to the output album:
- Run imagemine on a schedule via launchd to keep the output album growing. Use the
--launchdflag to write the agent configuration automatically:
Pass a number of minutes as the argument. If you omit it, imagemine will prompt you:
imagemine --launchd
# Run interval (minutes): 30Both commands write ~/Library/LaunchAgents/imagemine.plist and print the launchctl command to activate it. Pass --config-path to use a non-default database location:
imagemine --launchd 30 --config-path ~/work/imagemine.dbThen follow the printed instructions to load the agent:
launchctl load ~/Library/LaunchAgents/imagemine.plistSetting the screensaver on Apple TV
- Open the Photos app on Apple TV 4K.
- Navigate to Shared Albums or Albums at the top of the screen.
- Select the output album (
imagemine), then select Set as Screen Saver and confirm.
New images added to the shared album will appear in the screensaver automatically. Album photos that were never used before are preferred when picking, so the screensaver keeps getting fresh transformations instead of re-processing the same shots.
Scheduled runs on Linux and Windows
--input-dir gives non-macOS users the same "scheduled surprise" workflow: point it at a directory of photos and pair it with cron or a systemd timer.
# Configure once imagemine --config # set API keys and INPUT_DIR # cron: one image every 30 minutes */30 * * * * imagemine --output-dir ~/Pictures/imagemine-out --silent >> ~/imagemine.log 2>&1
Or with a systemd user timer (~/.config/systemd/user/imagemine.timer + .service):
# imagemine.service [Service] ExecStart=%h/.local/bin/imagemine --output-dir %h/Pictures/imagemine-out --silent # imagemine.timer [Timer] OnUnitActiveSec=30min OnBootSec=5min [Install] WantedBy=timers.target
systemctl --user enable --now imagemine.timerUse imagemine --history to check on scheduled runs: each run records a success/error status (with the error message) alongside timing and estimated cost.
Shell completions
Generate a completion script for your shell with --print-completion:
imagemine --print-completion bash | sudo tee /etc/bash_completion.d/imagemine imagemine --print-completion zsh > ~/.zsh/completions/_imagemine
Development
Setup
git clone https://github.com/hbmartin/imagemine
cd imagemine
uv sync --devTo run from the local source:
uv run imagemine path/to/photo.jpg
Run the linters, type checker, and tests:
uv run ruff check src --fix uv run pyrefly check src uv run ty check src uv run pytest tests/
Database
Every run is recorded in ~/.imagemine.db by default. Use --config-path to specify a different location. The runs table tracks:
| Column | Description |
|---|---|
started_at |
UTC timestamp when the run began |
input_file_path |
Absolute path to the source image |
resized_file_path |
Path to the temporary resized JPEG (deleted after generation) |
generated_description |
Story + image prompt from Claude |
description_model_name |
Claude model used |
desc_temp |
Temperature used for description generation |
desc_gen_ms |
Description generation time in milliseconds |
output_image_path |
Path to the generated image |
image_model_name |
Gemini model used |
img_temp |
Temperature used for image generation |
img_gen_ms |
Image generation time in milliseconds |
input_album_photo_id |
Photos item ID when input was selected from an album |
style |
Visual style applied to the image prompt |
status |
running, success, or error |
error |
Error message when the run failed |
desc_input_tokens |
Claude input tokens used for description generation |
desc_output_tokens |
Claude output tokens used for description generation |
The database uses SQLite WAL mode with a 5-second busy timeout, so an overlapping scheduled (launchd/cron) run and a manual run don't fail with "database is locked".
A new description is generated from Claude on every run unless --reuse-description or --from-run ID is given.
Using imagemine as a library
The pipeline is importable: run_pipeline raises imagemine.PipelineError subclasses (InputError, ResizeError, DescriptionError, GenerationError) instead of exiting the process, so failures can be handled programmatically.
import pathlib from rich.console import Console from imagemine import ( NullProgressReporter, PipelineConfig, PipelineError, init_db, run_pipeline, ) conn = init_db(pathlib.Path.home() / ".imagemine.db") config = PipelineConfig( output_dir=pathlib.Path("out"), image_path="photo.jpg", anthropic_api_key="sk-ant-...", gemini_api_key="AI...", ) try: result = run_pipeline(conn, Console(), config, progress=NullProgressReporter()) except PipelineError as e: print(f"failed: {e}")
Terminal UI
imagemine uses Rich for its terminal output:
- Labeled section rules divide the pipeline into phases: Resize → Describe → Style → Generate
- Live spinners with elapsed timers show progress during the two API calls — a
moonspinner for Claude description generation and asmileyspinner for Gemini image generation - Description panel renders the generated story as formatted Markdown inside a cyan-bordered panel
- Style tree shows the randomly selected style with its full description
- Summary panel displays source file, style, per-step timing, total wall time, and output path
--historytable lists recent runs with success/error status, per-step timing, total time, a proportional sparkline bar, and the estimated Claude cost--session-svgsaves a styled SVG of the entire terminal session alongside the generated image- Error tracebacks are rendered with Rich syntax highlighting when an API call fails
