Foldle — Focused Long-form Reading

Reveal the structure and reliable reading signals in long-form articles.

Foldle helps you stay oriented while reading long-form articles. It analyzes the article in your current tab and reveals its structure and useful reading signals without sending article text to a developer-operated server. READ WITH THE STRUCTURE VISIBLE • Build a reading map from headings and prose structure. • Surface key sentences with section-aware TextRank. • Mark conclusions, causality, contrast, evidence, conditions, negation, and uncertainty. • Optionally identify keywords, quantities, dates, percentages, ranges, and citations. • Explain what each multi-target signal means before you choose a highlight style. CONTROL WHAT YOU SEE Each signal can be enabled or disabled independently. Foldle provides global preferences and per-site overrides, so a technical reference, research article, and news story do not need to use the same reading setup. Highlight styles can be changed without reloading or changing the article text. WORKS WHERE YOU READ Open Foldle from the Chrome toolbar to use the Side Panel. Foldle can also display a Reading Rail inside supported pages. It is designed for ordinary HTTP and HTTPS long-form pages. Chrome internal pages, the Chrome Web Store, and other browser-restricted pages cannot be modified. LOCAL-FIRST ANALYSIS Article text and generated annotations are processed locally in the current page and extension runtime. Foldle does not upload or persist article text. Preferences may be stored with Chrome storage, and per-site overrides store only the relevant hostname and selected settings. Optional named-entity extraction uses Chrome's built-in local Prompt API when that capability and its local model are available. If the capability is unavailable, Foldle reports the feature as unavailable instead of sending text to a remote fallback. Foldle contains no advertising, no analytics SDK, no account system, no paywall, and no remotely hosted executable code.
