sphinx-clarity 1.3.0.2

A clean Sphinx theme with phosphor-green / UV-violet dual-accent color system

Clarity

A clean, modern Sphinx theme with a phosphor-green / UV-violet dual-accent palette and a built-in AI documentation assistant.

Features

• Dark / light / system theme toggle, remembered across visits
• Dual-accent palette -- phosphor-green in dark mode, UV-violet in light
• Three-column layout -- sidebar, content, on-this-page table of contents
• Responsive -- works on desktop, tablet, and mobile
• Keyboard navigation -- arrow keys for prev/next, / to focus search
• Text size controls -- readers can scale the article 75 % -- 150 %
• Language-tagged code blocks with Pygments-styled syntax colors
• Dual logo support -- different images for dark and light modes
• AI assistant -- page-aware chatbot with /goto navigation and /read page-summarization commands, powered by your own OpenRouter key
• GDPR / ePrivacy consent -- built-in banner, no third-party plugins, nothing stored until the reader accepts

Install

pip install sphinx-clarity

Quick start

Create a new Sphinx project (if you do not already have one):

mkdir docs && cd docs
sphinx-quickstart

Edit conf.py to use Clarity:

html_theme = "clarity"

html_theme_options = {
    "default_theme": "system",    # "dark", "light", or "system"
    "font_stack": "default",      # "default" or "system" (no remote fonts)
    "navigation_with_keys": True,
    "show_toc_level": 2,
}

Build and serve locally:

sphinx-build -b html . _build/html
python -m http.server -d _build/html 8000

Open http://localhost:8000.

Optional: enable the AI assistant

Add your OpenRouter settings to conf.py:

html_theme_options = {
    # ...
    "chatbot_enabled": True,
    "chatbot_model": "openai/gpt-oss-120b:free",
}

The reader supplies their own OpenRouter key in the chat panel -- it is stored locally in the browser, never sent to you. Set "chatbot_enabled": False to ship the theme without the assistant.

Add a logo

Drop logo files into your Sphinx _static/ folder and reference them:

html_theme_options = {
    # ...
    "light_logo": "logo-light.svg",
    "dark_logo": "logo-dark.svg",
}

Full walkthrough -- from zero to a docs site

This is a longer recipe for someone who is new to Sphinx. It mirrors how Clarity's own docs are organized, so you end up with a similar layout.

1. Create a new project

mkdir my-docs && cd my-docs
python -m venv .venv
source .venv/bin/activate
pip install sphinx sphinx-clarity
sphinx-quickstart docs

Accept the prompts (separate source and build directories, project title, author, release). You now have:

my-docs/
  docs/
    Makefile
    make.bat
    source/
      conf.py
      index.rst
    build/

2. Switch to Clarity

Open docs/source/conf.py and replace the html_theme line, then add a minimal options block:

html_theme = "clarity"

html_theme_options = {
    "default_theme": "system",
    "font_stack": "default",
    "navigation_with_keys": True,
    "show_toc_level": 2,
}

If you set release = "v0.1.0-000" near the top of conf.py, Clarity shows the tag in the sidebar. When release is missing, an orange "version not set in conf.py" warning appears in the sidebar so you remember to fill it in before publishing.

3. Write your first page

Edit docs/source/index.rst:

My Project
==========

Welcome!

.. toctree::
   :maxdepth: 2

   guide

Create docs/source/guide.rst alongside it:

Getting Started
===============

Install::

   pip install my-project

4. Build and preview

sphinx-build -b html docs/source docs/build/html
python -m http.server -d docs/build/html 8000

Open http://localhost:8000. Toggle the theme, scale the text with the - / + buttons, try the keyboard navigation.

5. Add a logo (optional)

Put your logo files in docs/source/_static/ and reference them from conf.py:

html_theme_options = {
    # ...
    "light_logo": "logo-light.svg",
    "dark_logo": "logo-dark.svg",
}

6. Enable the AI assistant (optional)

Flip on the chatbot and pick a model:

html_theme_options = {
    # ...
    "chatbot_enabled": True,
    "chatbot_model": "openai/gpt-oss-120b:free",
}

Rebuild. Each reader opens the chat with the ∂ button, pastes their own OpenRouter key (stored only in their browser), and can ask questions about the current page.

7. Tweak the assistant at runtime

Click the ⚙ button in the chat panel to open the settings overlay. Every chatbot_* option from conf.py is editable there -- model, temperature, reasoning effort, system prompt. Overrides are saved in the reader's own browser and don't affect anyone else.

8. Keep going

• configuration.rst -- every html_theme_options field and default.
• chatbot.rst -- assistant setup, slash commands, settings overlay.
• privacy.rst -- exactly what Clarity stores and where.

You can add more pages to docs/source/, link them from the toctree in index.rst, and rerun sphinx-build. That's the whole loop.

Documentation

Full documentation -- configuration reference, privacy details, chatbot setup -- is published at the project docs site, and the sources live under docs/source/ on GitHub if you prefer to browse them there.
