Gemini¶

Gemini targets gemini.google.com. All methods shared with ChatGPT are documented on the Shared Interface page — this page covers only what is specific to Gemini.

Guest mode vs logged-in mode¶

Gemini works in two modes depending on whether you are logged in:

Feature	Without login	Logged in
Text queries	✓	✓
File upload	✗	✓
Image generation	✓	✓
Watermark removal	✓	✓

Attempting file upload without a logged-in session raises LoginRequiredError. Run Gemini.setup() and log in to enable it.

Supported attachments¶

Gemini.SUPPORTED_ATTACHMENTS is the set of file extensions accepted for upload. Passing any other extension to send_message() or query() raises a ValueError before touching the browser.

print(Gemini.SUPPORTED_ATTACHMENTS)
# {'.png', '.jpg', '.jpeg', '.gif', '.webp', '.pdf', '.csv', '.txt', '.json'}

`hermex.gemini.Gemini` ¶

Bases: Scraper

Scraper for Google Gemini (gemini.google.com).

Supports text queries, file uploads, and downloading generated images. Works in guest mode for basic text queries; file upload requires a logged-in session established via Gemini.setup().

Generated images are optionally post-processed to remove the Gemini watermark via remove_watermark=True on query() or get_last_response().

`SUPPORTED_ATTACHMENTS = {'.png', '.jpg', '.jpeg', '.gif', '.webp', '.pdf', '.csv', '.txt', '.json'}` `class-attribute` `instance-attribute` ¶

Watermark removal¶

Gemini watermarks its generated images. Pass remove_watermark=True to query() or get_last_response() to strip it automatically using OpenCV template matching — no external service involved.

response = gemini.query("Generate an image of a sunset.", remove_watermark=True)

remove_gemini_watermark() is also available standalone, if you want to strip a watermark from an image file without going through query() or get_last_response():

from hermex import remove_gemini_watermark

remove_gemini_watermark("input.png", "output.png")

`hermex.remove_gemini_watermark(input_path, output_path)` ¶

Remove the Gemini watermark from an image file.

Parameters:

Name	Type	Description	Default
`input_path`	`str \| Path`	Path to the image to process.	required
`output_path`	`str \| Path`	Path to write the result to. Pass the same value as `input_path` to overwrite the file in place.	required

Default URL¶

open_url() defaults to https://gemini.google.com and raises ValueError if a non-Gemini URL is passed.
