AI is already using your work to accomplish millions of tasks per day. Index tells you how much you're contributing — and pays you for it.

The web was built for humans. Our clicks and our eyeballs shaped how information got discovered and monetized — and in doing so, unleashed more knowledge, commerce, and connection than any institution in human history.
But the web's primary user is changing. AI agents are displacing the attention that built the content economy, without replacing the revenue that sustained it.
Index exists to close that gap.
The new infrastructure for content in the AI era. #
Reach millions of agents, not just human readers.
AI agents now handle the information work that humans used to do through search. Index puts your content in front of those agents, across legal research, financial due diligence, sales intelligence, healthcare, and compliance. Your work reaches an entirely new class of reader — one that operates at scale.
Get paid when an agent uses your content to produce a response.
Compensation tied to actual contribution, calculated from the moment your content was used. Not a flat fee negotiated once and forgotten. Whether you’re an independent writer or a global news organization, the math is the same.
Know what you’re worth to the agentic web, and have the numbers to prove it.
Index gives you a real-time dashboard: which of your content agents cite most, which tasks it supports, whether it’s uniquely valuable or going up against commodity coverage. This is the data you’ve never had — and the benchmark you can bring into any negotiation.

Index is not just for media companies. The Shapley math doesn’t care about brand size — it measures contribution quality. A writer with uniquely authoritative expertise in a specific domain can earn more per citation than a large publication with commodity coverage. Index gives independent creators and Substack writers the same access to the agentic marketplace as it does large newsrooms and storied media empires.

Parallel was founded in 2023 by Parag Agrawal with the mission to keep the web open, competitive, and transparent.
