Two Hraness products use Oh: Sponge and Wordcell. Each entry below gives the product's one-sentence description of what it uses Oh for.
Oh is an open-source memory framework for agents. It stores each fact with its source and records every accepted change so it can be inspected. An agent's working memory stays in a separate store that can be purged, until the host application's own code adopts a record into the reviewed store. Latest release: v0.12.0.
Products that use Oh
Sponge. Sponge keeps its hosted agent's working memory in a server-side Oh store that expires with the session, separate from the product data in Sponge's own databases.
Wordcell. Wordcell rebuilds a disposable Oh graph from your Markdown to answer named graph queries with source proofs; Markdown and Git stay the record, and search does not use Oh's memory retrieval.
Oh or Wordcell for your project
Sponge runs Oh on its server as its agent's working memory, and that store is the record for those working notes. Wordcell keeps no record in Oh. A default query builds a graph in memory from your notes and discards it, wordcell graph rebuild writes a disposable local cache, and your Markdown stays the only record. Oh's README draws the line the same way: use Oh to build an application's memory layer, and use Wordcell to maintain and query a Markdown knowledge base.
How a product gets listed
A product appears here when the Hraness portfolio registry records its relation to Oh with a one-sentence description. Each listed product depends on a published Oh release, pins its own version, and upgrades when it chooses, so Sponge and Wordcell can run different Oh versions at the same time. When a product starts or stops using Oh, or changes what it uses Oh for, its entry changes with it.
