Show HN: AI Agents for Osint/Sigint

Ritwik launched Makra, a memoization-driven web scraping engine for AI agents, claiming it cuts data retrieval costs to one-tenth of prior generations while eliminating hallucinations and prompt injection. The tool, presented as a Show HN post on Aug. 27, 2026, uses a read-only browser harness to extract structured data at scale, addressing the limitations of long-context LLMs in dynamic web environments.

The State of AI Web Scraping in 2026 LAUNCH · AUG.27.2026 · Ritwik 75% of the web is dynamic. Basically database records presented in HTML. Built for humans. For Agents, this problem was solved by: RAG was the first generation 2024 - And then, long-context LLMs took it to a completely new level 2025 Fast-forward to 2026, and we're basically dumping anything and everything into the context windows; taking Nvidia to the moon. This consists of claws, browser/computer-use, and agentic crawlers, and scrapers. These have made it easier to retrieve data, but the cost has stayed the same. Underneath, these still rely on long-context LLMs. And, here's where they fall short: - Cost at scale: for large datasets, cost grows linearly on a per-page basis. - Hallucinations: LLMs are prone to hallucinations - Context pollution and prompt injection Let me now show you what we have built: Memoization-driven Knowledge and Data Retrieval It's an work-in-progress implementation for a continual learning harness focusing on Browser-use. Large-request correctness versus cost Scatter plot of correctness against average USD cost for Makra, Exa, and Firecrawl. Lower cost is toward the left. Building applications on top of a memoization-engine like Makra / solves all 3 of these problems: - Lower cost at scale: as layouts are memoized, cost comes down to a vector query. - Makra extracts data like a traditional scraper. So, hallucinations? Theoretically, none. - Your agentic loop only has to deal with the DOM nodes it's concerned with: More signal, less noise. We have built an in-house browser harness read-only for now that does the following for you: - Spins up a browser instance and sets up proxies. - Extracts any structured or tabular data from the web for you. - And you can do all this at 1/10th the cost of all the other previous generations.
