Goldfish brain or galaxy brain?

Show HN: A memory database that forgets, consolidates, and detects contradiction

Dev drops a “forgetful” memory DB; crowd splits: genius tool or “slopcoded” hype

TLDR: YantrikDB claims it fixes AI memory by forgetting old stuff, consolidating duplicates, and flagging conflicts. Commenters are split between intrigued (“half-life for memories!”) and skeptical (“show benchmarks”), with one calling it a “slopcoded brainwave” while the author says existing tools fell apart at ~5k notes.

A new “memory” database called YantrikDB just hit the stage promising to forget old stuff, merge duplicates, and flag contradictions so your AI agent doesn’t drown in its own notes. The pitch: real memory isn’t a junk drawer; it should decay over time, compress 20 near-duplicate meeting notes into a handful, and scream when “CEO is Alice” collides with “CEO is Bob.” There’s a server, a plug-in mode for AI coding tools, and an embeddable library—and the dev flexes chaos tests, encryption, and maturity notes.

But the comments? Pure split-screen. One camp is all-in on the half-life idea and wants the juicy details: “What’s the consolidation loop—random sampling and an AI merge?” Another camp is pounding the table for proof: benchmarks, real-world wins, and fewer diagrams. The sharpest jab called it a “slopcoded brainwave,” while a more measured skeptic asked, “Did you check if this leads to any actual benefits?” The author fires back with lived pain: memory in a popular vector store turned “to garbage at ~5k” notes, causing outdated facts and contradictions.

Meanwhile, drive-by comedians are loving the premise: “Finally, a database that forgets my meetings,” and “Can it forget my sprint tickets too?” Under the jokes lies a bigger fight: Do we really need a complex ‘thinking’ memory layer, or should large language models handle it at prompt time? Whether it’s the next brain for agents—or just a neat science project—the crowd wants receipts, not vibes.

Key Points

  • YantrikDB adds forgetting (half-life decay), consolidation, and contradiction detection to AI memory management.
  • It can run as a network server, MCP server, or embedded library for Python and Rust.
  • Operational features include HA clustering (2-voter + 1-witness), per-tenant quotas, Prometheus metrics, and AES-256-GCM encryption.
  • Performance on a 2-core LXC cluster shows recall p50 ~112ms, p99 ~190ms; ~5ms p50 with pre-computed embeddings.
  • v0.5.11 is a hardened alpha with extensive testing, chaos experiments, and production use in the YantrikOS ecosystem.
