# Wordcell

> Wordcell keeps decisions, plans, and sources as Markdown beside your code,
> so coding agents can find them from the file they are about to change.

A new coding-agent session can read your code, but not the decisions that
stayed in the last session's chat. Wordcell keeps those decisions as Markdown
files beside the repository, with the plans that depend on them and the web
pages and PDFs that informed them. Tie a note to the paths it explains, and an
agent about to change that code runs one command to get the notes and plans
for that path. Exact search, backlinks, and Git history run on your machine
with no account or model, and every index rebuilds from files you can read in
any editor. Wordcell is free and open source.

When to use this site:
- Use wordcell.io to learn what Wordcell does, what stays on your machine, and
  the current install command.
- Use /developers for the coding-agent workflow: context for a repository path,
  AGENTS.md rules, Git history, and the Agent Skill.
- Use /docs for the documentation: a tutorial, how-to guides, the command
  reference, and design explanations.
- Use /blog for longer posts on why Wordcell works the way it does.

## Pages

- [Wordcell](https://wordcell.io/): Quick start, connecting a local agent, how
  notes, links, and search work, the selected-passage, context-size, and
  SciFact reranking measurements, how Wordcell uses Oh, comparisons, publishing selected
  notes, what stays local, and the install command.
- [For developers](https://wordcell.io/developers): The coding-agent workflow:
  code-path context, scoped rules, note history, and the Agent Skill.
- [Benchmarks](https://wordcell.io/benchmarks): Wordcell's selected-passage,
  context-size, and SciFact reranking measurements with their limits; the Oh kernel's
  500-question LongMemEval-S study of Oh semantic retrieval against BM25, its
  LoCoMo run, and its earlier 60-question pilot with Supermemory and BM25, all
  measured by Oh rather than through a Wordcell vault; and figures that other
  memory systems publish, each with its source.

- [Wordcell vs Mem0: agent notes or per-user app memory](https://wordcell.io/compare/mem0): Where memory
  lives, how memories form, whose memory it is, the Platform and open-source
  split, and cost, with Mem0's documentation checked on September 26, 2026.
- [Wordcell vs Supermemory: files or a hosted memory API](https://wordcell.io/compare/supermemory):
  Where memory lives, how memories form, cost with Supermemory's pricing

  when to choose each.

  into tutorials, how-to guides, reference, and explanation, with the install
  command.

  tutorial.
- [Overview](https://wordcell.io/docs/overview): What Wordcell does, how to
  install it, and how a coding agent uses a vault, on one page.
- [Use Wordcell with a coding agent](https://wordcell.io/docs/agent-workflow):
  Set up, query, maintain, and revise repository memory.
- [Reference](https://wordcell.io/docs/reference): Exact commands, formats,
  SDK imports, optional adapters, and the local MCP server (wordcell mcp)
  with its tools and client settings.
- [Publish](https://wordcell.io/docs/publish): Select notes and build a static
  site.
- [Migrate from Supermemory](https://wordcell.io/docs/migration-from-supermemory):

  notes, and see what does not transfer.
- [Sync a vault with Git](https://wordcell.io/docs/sync): Keep one vault
  current on several machines with a private repository and a scheduled
  commit and push.
- [Comparisons](https://wordcell.io/docs/comparisons): Markdown tools such as
  QMD, Basic Memory, and Obsidian, Claude Code's built-in memory and
  claude-mem, and agent memory services such as Supermemory, Mem0, and Zep,
  compared with Wordcell from primary sources.
- [Evidence](https://wordcell.io/docs/evidence): The reproducible
  context-payload study and the study of whether selected passages contain the
  answer.
