A mobile agent that follows the people, companies and niche subjects a user names, then condenses duplicate coverage from many outlets into single cited summaries.

About Causari

The first content-addressable ledger for AI agents. Every prompt, model, read, write and reasoning becomes an immutable causal event, captured at the wire, no agent cooperation required. Trace, bisect, revert and explain every line your agents wrote. re audit reads plain git history, detects AI-authored commits from verifiable metadata ( Co-Authored-By trailers, bot authors, aider markers) and measures how many of those lines are still alive at HEAD. Every number carries its evidence class: VERIFIED (explicit metadata) is never mixed with PROBABLE (heuristic).

About Zetik

Zetik is a personal intelligence agent for iOS and Android that monitors news, podcasts, research papers, forums, filings and code on a user's behalf. A tracker is created from a single typed or spoken sentence and starts running within seconds. Zetik picks the sources itself, though users can pin trusted outlets or connect their own. When one story appears across dozens of publications, the agent merges the coverage into a card explaining what happened and why it is relevant, with every source linked. Alerts arrive only when something meaningful changes, and briefings can be delivered as an app feed, push notifications, a newsletter or RSS. Pricing is not stated on the homepage.
