Follow Anywhere
The pipeline

From anything you care about to updates that matter.

Start with a URL, a topic, a list of sources, or an OPML file. Follow Anywhere turns raw inputs into things it can follow, then helps separate meaningful developments from web noise.

Five stages

One pipeline from input to follow

The collection mechanism can vary, but the user-facing mental model should stay stable.

01

Input

Paste a webpage, describe a topic, add multiple URLs, or import an OPML file.

02

Parse

Extract and normalize sources. OPML structure and feed URLs are parsed deterministically rather than guessed by AI.

03

Resolve

Determine whether each input is a feed, webpage, known source, or higher-level topic.

04

Understand

Group related sources, identify meaningful changes, remove repetition, and judge relevance.

05

Follow

Surface useful updates with original source links — in Follow Anywhere or through open formats when useful.

Engineering principle

Use AI for understanding, not for everything

Reliable mechanics should stay deterministic. AI earns its place where understanding is actually required.

Deterministic core

OPML/XML parsing

URL normalization

Source identity

Change history

Deduplication primitives

AI-assisted understanding

Source understanding

Topic matching

Semantic change detection

Grouping

Relevance and summarization

OPML / RSS

URLs

One model, many inputs

Users should not need to understand whether a source happens to expose RSS, an API, or only HTML before they can follow it.

Start with what you already follow.

Paste a URL, describe a topic, or import the subscriptions you already have.
