AI Data

Crawl4AI

β˜… 4.3

Open-source web crawler designed for LLMs and AI agents with structured extraction and browser automation.

#LLM-first output format #Built-in browser automation with anti-bot support #Structured data extraction via LLM-guided parsing
#2

Atlas

β˜… 4.3

Open-source local-first cognitive memory system implementing AGM-compatible belief revision that automatically re-evaluates downstream beliefs when facts change, with SHA-256 hash chain for data integrity.

#Highly secure & local-first #Boosts workflow efficiency #User-friendly interface
#3
AI Data

sqlsure

β˜… 4.3

A deterministic SQL semantic inspector that catches silently-wrong AI-generated queries β€” double-counting, bad joins, exposed PII β€” in about 0.1 ms before they run. Works as a CI gate, an MCP server, or a library.

#Deterministic semantic checks β€” catches double-counting, wrong joins, and exposed PII #Three doors: CI gate, MCP server, and embeddable library #Judges SQL against facts from dbt tests, PK/FK declarations, or live DB introspection

Adaptive Recall

β˜… 4.0

Adaptive Recall is a hosted memory system for AI applications that goes far beyond simple vector search. It stores, recalls, and manages long-term memory for agents and apps over MCP or a plain REST API, and β€” unlike a static embeddings store β€” it actively learns. Four retrieval strategies run in parallel (vector similarity, temporal recency, full-text keyword, and knowledge-graph traversal), and the system learns which to prioritize for each query type. Results are ranked with ACT-R cognitive scoring from 30 years of cognitive-science research, factoring in recency, access frequency, entity connections, and validated confidence. A knowledge graph is built automatically from stored memories, memories move through a confidence-based lifecycle and fade when unused, and an ML pipeline trains on your usage patterns β€” validating every parameter change against real query history before adopting it. A simple eight-tool API (store, recall, update, forget, graph, status, snapshot, feedback) covers everything, with Bearer-token auth and JSON in/out. Free, Starter, Pro, and Business plans are available.
