openreview-downloader 0.1.6

Download OpenReview papers by decision.

OpenReview Paper Downloader

Simple download, listing, and search of oral, spotlight, accepted, or rejected papers from OpenReview into tidy folders by decision.

Despite the name, this works for any OpenReview-hosted conference (NeurIPS, ICLR, ICML, etc.).

Installation

pip install openreview_downloader

Usage

The CLI saves PDFs into downloads/<venue>/<decision>/ with sanitized filenames.

Available decisions:

• oral – Oral presentations
• spotlight – Spotlight presentations
• accepted – All accepted papers
• rejected – Rejected papers
• all – Accepted and rejected papers

Authentication

Some OpenReview venues require authenticated API access. If OPENREVIEW_USERNAME and OPENREVIEW_PASSWORD are present in the environment, the CLI uses them automatically and does not prompt.

To save credentials for future runs:

ordl auth

You can also check or clear saved credentials:

ordl auth status
ordl auth logout

When no environment or saved credentials are available, ordl asks for your OpenReview email and password interactively before contacting OpenReview.

Latest ICML example (2026)

OpenReview may require authenticated API access for ICML 2026. Run ordl auth once, or set OPENREVIEW_USERNAME and OPENREVIEW_PASSWORD in your environment.

Download all ICML 2026 spotlight papers:

ordl spotlight --venue-id ICML.cc/2026/Conference

If you omit DECISIONS while listing or searching, the CLI defaults to accepted papers and exits without downloading:

ordl --head 20 --venue-id NeurIPS.cc/2025/Conference

Search, grep, and regex workflows

Search over title, authors, abstract, keywords, decision, venue, id, and paper number. --search and --grep are aliases; matching is case-insensitive by default.

Preview accepted papers matching a text query:

ordl accepted --list --search diffusion --head 2 --venue-id NeurIPS.cc/2025/Conference

Preview regex matches and show snippets plus counts:

ordl accepted --list --regex 'diffusion|transformer' --head 2 --venue-id NeurIPS.cc/2025/Conference

Download the same selection by rerunning the same query without --list:

ordl accepted --search diffusion --venue-id NeurIPS.cc/2025/Conference

Download only the first 10 matches:

ordl accepted --search diffusion --head 10 --venue-id NeurIPS.cc/2025/Conference

Require multiple terms or patterns by repeating the flags:

ordl accepted --list --grep diffusion --grep protein --venue-id NeurIPS.cc/2025/Conference

For scripts, agents, and crawlbots, use JSON Lines output while listing:

ordl accepted --list --search diffusion --head 2 --format jsonl --venue-id NeurIPS.cc/2025/Conference

The first JSON line is a summary with the number of matched and shown papers; each following line is one paper record with stable fields such as id, number, decision, title, authors, pdf_path, match_count, and matches.

JSONL keeps progress logs on stderr so stdout can be piped directly into tools:

{"decisions": ["accepted"], "head": 2, "matched_papers": 710, "shown_papers": 2, "type": "summary", "venue_id": "NeurIPS.cc/2025/Conference"}
{"authors": "Jiyao Zhang, Zhiyuan Ma, Tianhao Wu, Zeyuan Chen, Hao Dong", "decision": "accepted", "id": "CB8jwNE2vV", "match_count": 1, "matches": [{"count": 1, "field": "abstract", "query": "diffusion", "snippet": "... high-dimensional representation, we introduce an occupancy-[diffusion] model with voxel-level conditional guidance and force closu..."}], "number": 29119, "pdf_path": "downloads/neurips2025/accepted/29119_CADGrasp_Learning_Contact_and_Collision_Aware_General_Dexterous_Grasping_in_Cluttered_Scenes.pdf", "title": "CADGrasp: Learning Contact and Collision Aware General Dexterous Grasping in Cluttered Scenes", "type": "paper", "venue": "NeurIPS 2025 poster", "venueid": "NeurIPS.cc/2025/Conference"}

Other Conferences (ICLR, ICML, etc.)

Just change the --venue-id to the appropriate OpenReview handle.

ICLR 2025 orals only:

ordl oral --venue-id ICLR.cc/2025/Conference

ICLR 2025 accepted papers (all formats):

ordl accepted --venue-id ICLR.cc/2025/Conference

ICML 2025 oral + spotlight:

ordl oral,spotlight --venue-id ICML.cc/2025/Conference

You can use any other OpenReview venue ID in the same way.

CLI Options

• --regex PATTERN – Regex search across paper metadata; repeat to require multiple patterns
• --case-sensitive – Make search and regex matching case-sensitive
• --format text|jsonl – Output format for --list; jsonl is convenient for automation
