remex-cli 1.4.0

Local-first RAG library — ingest files and SQLite, query semantically, pipe results into any AI agent

Remex

Your private knowledge base — fully offline, never leaves your machine.

Remex turns any folder of documents — PDFs, Word files, notes, spreadsheets, code — into a private, searchable knowledge base. Ask questions in plain language and get answers grounded in your own files, with sources cited.

Everything runs on your machine. No cloud account. No API key required for search. Bring your own AI provider (Anthropic, OpenAI, or a local Ollama instance) only when you want synthesised answers.

Remex Studio

Native desktop app for Windows. No terminal required.

⬇ Download the latest release

⚠️ Windows SmartScreen warning Windows may display a "Windows protected your PC" warning when downloading or installing Remex Studio. This happens because the app is not yet code-signed with a paid certificate — the software is safe and fully open source, feel free to audit the source code in this repository. To proceed: click "More info" then "Run anyway".

Python CLI & Library

pip install remex-cli            # core — ingest + query
pip install "remex-cli[api]"     # + FastAPI sidecar (used by Studio)

Quick start

# Scaffold a project
remex init

# Ingest a folder of documents
remex ingest ./docs

# Semantic search
remex query "how does authentication work?"

# AI-synthesised answer (requires ANTHROPIC_API_KEY, OPENAI_API_KEY, or a running Ollama)
remex query "how does authentication work?" --ai

Command reference

Command	Description
remex init [path]	Scaffold docs/, remex.toml, and .gitignore entries
remex ingest <dir>	Ingest files from a directory into a collection
remex ingest-sqlite <db>	Ingest rows from a SQLite table
remex query <text>	Semantic search; add --ai for an AI-synthesised answer
remex sources	List all ingested source paths in a collection
remex stats	Show chunk and source counts
remex delete-source <path>	Remove all chunks for a specific source
remex purge	Remove chunks whose source file no longer exists on disk
remex reset	Wipe an entire collection
remex list-collections	List all collections in a database
remex serve	Start the FastAPI sidecar on localhost:8745

remex <command> --help    # full option reference for any command

Use as a library

from remex import ingest, query

# Ingest a folder
result = ingest("./docs", collection_name="my-kb")
print(f"{result.chunks_stored} chunks stored")

# Search
results = query("how does auth work?", collection_name="my-kb")
for r in results:
    print(f"[{r.score:.3f}] {r.source}  →  {r.text[:120]}")

---

Configuration

Drop a remex.toml in your project root (or run remex init to generate one):

[remex]
db              = "./remex_db"
collection      = "my-kb"
embedding_model = "all-MiniLM-L6-v2"

# chunk_size     = 1000   # tokens per chunk
# overlap        = 200    # overlap between chunks
# min_chunk_size = 50     # discard chunks shorter than this
# chunking       = "word" # "word" or "sentence"

CLI flags always override remex.toml values.

Supported embedding models

Preset	Model	Size	Notes
Light	all-MiniLM-L6-v2	22 MB	Default — fast, good accuracy
Balanced	intfloat/e5-base-v2	438 MB	Better retrieval quality
Multilingual	paraphrase-multilingual-MiniLM-L12-v2	470 MB	50+ languages
Large (Pro)	BAAI/bge-large-en-v1.5	1.3 GB	Best English accuracy
E5 Large (Pro)	intfloat/e5-large-v2	1.3 GB	Strong retrieval benchmark
Long ctx (Pro)	nomic-ai/nomic-embed-text-v1.5	547 MB	8 192-token context window

Any model from SBERT, HuggingFace sentence-similarity, or Ollama can be used by typing the model name directly.
