What you are installing

A memory that would rather say nothing than guess.

RE-call stores notes, decisions, and project history, then searches them by meaning.

When nothing matches with enough confidence, it abstains instead of handing you the nearest note.

The middle question recall quickstart asks

Output

[ABSTAIN GAP] query='penguins on Mars?'
  reason: no confident match in this corpus
  evidence: rate-limits.md · confidence 0.30

A low-confidence match is shown as evidence, not presented as an answer.

The moving parts

Three things, and only one of them is RE-call.

Most of the confusion in a first install comes from not knowing which piece a command is talking to. There are only three.

Piece	What it does	You touch it
A PostgreSQL database	Stores your notes and their vector embeddings.	Once, during setup.
The RE-call package	Indexes markdown and decides whether a result is safe to use.	Every query.
The MCP server	Lets Claude Code query your local memory.	Optional.

New, and in beta

On Windows, a wizard can do the whole install for you.

One window asks a short list of questions, then brings up the database, indexes your folders and writes the Claude Code wiring while you watch the log.

It is a beta and it is not code signed yet, so the download page says plainly which machines Windows will let it run on. I am looking for testers, and for comments on how it went.

What you give up by using it

Nothing that cannot be recovered. The wizard writes the same configuration file the terminal flow writes, and the install it produces is one you can re-run, inspect, or hand to somebody else.

The full install stays the path on macOS and Linux, and the path to fall back to if the installer will not start.

The rest of this site

Four pages you will want after the install, and not before.

Start at step one.

Install two things, then verify each step as you go.
