Realtime financial context for AI agents: what changed, why it matters, and who is affected. Output is context-efficient for AI agents, with sources and evidence on every result. Market news is filtered for novelty so you can tell new information from stories the market already has. Developments are compact packages covering what happened, which public companies are exposed, and the evidence, clustered into events you can follow. Official outlooks are structured as they are published so you can compare guidance across companies, read revision history, filter by fiscal period, and check outlooks against reported results. Wording changes in earnings releases are structured and queryable. Any of these can be turned into an alert that delivers new results by email, Telegram, or webhook. Ultralayer does not provide financial advice. Skills at https://github.com/UltralayerHQ/ultralayer-plugin/tree/main/skills
Connect Claude or any MCP client to Thread Otter, a GTM agent for founders. Free tools with no key: find_buyer_threads (give it a website URL and get recent Reddit threads where that product's buyers are asking for it, report in ~3 minutes), reddit_demand_board (weekly demand across 40 communities with thread receipts), and subreddit_rules (promotion posture for 2,000+ profiled subreddits).
