aeris

The command-line client for aeris, a personal notes app used by humans (a web UI) and AI agents (this CLI). It talks to an aeris server over HTTP; it never touches the database.

Install

uv tool install aeris

Configure

Point the CLI at your server with a URL and a token's secret, either as environment variables (handy in agent sandboxes):

export AERIS_URL=https://your-aeris.vercel.app
export AERIS_TOKEN=your-secret

or in ~/.aeris.yaml (another file can be named with AERIS_CONFIG_PATH):

url: https://your-aeris.vercel.app
token: your-secret

Environment variables win over the file.

Use

aeris list [--limit 30] [--last "2 days"] [--tag T] [--order created|updated]
aeris show ID [ID...]
aeris search WORDS... [--tag T] [--limit 30]     # phrase search, ignoring case and accents
aeris ask WORDS... [--tag T] [--limit 10]        # closest notes in meaning, with scores
aeris tags
aeris add [-m TEXT]                              # else piped stdin, else your editor
aeris append ID [-m TEXT]                        # adds a paragraph; never conflicts
aeris edit ID                                    # in your editor
aeris edit ID --stdin [--expected-updated-at T]  # from stdin, for scripts and agents
aeris delete ID
aeris export [PATH | -] [--force]                # every note as JSON Lines: a backup

ask ranks notes by semantic similarity (cosine, higher is closer). Scores are relative: a good match often scores only 0.3–0.5, so compare results with each other rather than with a fixed bar.

Tags come from lines like Tags: #project/aeris, #ideas in a note. The editor is $VISUAL, else $EDITOR, else vi; it only opens in an interactive terminal.

For agents and scripts

• Add --json to any command (except export) to get the server's JSON.
• Exit codes: 0 success, 1 error, 2 usage error.
• With --json, errors are JSON on stdout: {"error": ..., "status": ...}. An edit conflict (409) also carries current, the note's latest version.
• Prefer append to add information. To rewrite a note safely, read its updated_at with show --json, then edit --stdin --expected-updated-at that value: the edit fails instead of overwriting someone else's change.

Upgrading from 0.4

0.5 talks to the aeris server instead of the database:

• ~/.aeris.yaml needs url and token instead of database_url.
• display is now show; list shows the newest notes first.
• web and reset-db are gone: the web UI is part of the server.
