SummarizePaper :books::robot:

AI tools for researchers, from reading a paper to presenting it. Summaries and a chat that answer from the full text of a paper, collections compared cell by cell, alerts that follow a field, and tools to write, submit and present research. Papers from arXiv, bioRxiv, medRxiv, journals and other preprint servers, in English and French.

What it does :sparkles:

Every answer rests on the paper itself: the full text is read when its license allows it (CC BY, BY-SA, BY-NC, BY-NC-SA, CC0), the abstract otherwise, and claims are checked against the passages they come from, with a link to each passage.

Free tools are open to every account; :star: marks Premium and :star::star: Premium+.

Local setup :floppy_disk:

python3.12 -m venv venv
venv/bin/pip install -r requirements.txt
export SECRET_KEY=dev OPENAI_KEY=sk-...
venv/bin/python manage.py migrate
venv/bin/python manage.py runserver

Websockets need Redis on 127.0.0.1:6379 (brew services start redis).

Tests: venv/bin/python manage.py test summarizer and node --test tests/*.test.cjs.

Translations: French strings live in locale/fr/LC_MESSAGES/django.po; compile them with python manage.py compilemessages. Guides are Markdown in content/guides/{en,fr}/, copied into the database with python manage.py import_guides.

Configuration (Heroku config vars)

Variable	Purpose
SECRET_KEY, ON_HEROKU, SITE_URL	Django secret key, production settings, public address
DATABASE_URL, REDISCLOUD_URL	Set by the Postgres and Redis Cloud add-ons
OPENAI_KEY	OpenAI API key
SECRETCMTA	SMTP password (outgoing email)
GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET	Google sign-in
OPENALEX_API_KEY	Optional, free: raises the OpenAlex daily budget and reads full texts OpenAlex keeps
ADS_TOKEN, S2_API_KEY	NASA ADS and Semantic Scholar, sources of the citation alerts
SCOOP_DRAFT_KEY	Encrypts the scoop watch's kept drafts
STRIPE_SECRET_KEY, STRIPE_WEBHOOK_SECRET, STRIPE_PRICE_*	Premium and Premium+ (monthly, yearly, EUR and USD); closed while unset
UMAMI_WEBSITE_ID, SENTRY_DSN	Optional analytics and error reporting

Umami events (static/summarizer/js/funnel.js) carry only allowlisted language, period, placement and tool identifiers, never queries, manuscript text or email addresses. Stripe webhooks and UserPlan remain the source of truth for subscriptions.

Deployment and scheduled jobs

git push heroku master; the release phase of the Procfile applies migrations.

One hourly Heroku Scheduler job, python manage.py send_digest, sends the digests that are due, then counts the day's terms for the rising topics, writes the weekly letters and sends scoop, citation, version, publication, saved-search and topic-map alerts and research placement reminders, within what is left of the hourly email budget.

Other commands:

Command	Purpose
letters_write	Write the weekly letters of a week now, or print what they would hold
trends_backfill, trends_calibrate	Count past weeks for the rising topics; print rising terms with their statistics
scoop_calibrate, citations_calibrate, teams_calibrate, students_calibrate	Run a tool on sample inputs and print what it counts and why, to check thresholds (they write nothing)
digest_stats	Click-through rate by rank, votes and unsubscriptions of the digests
embed_papers	Embed summarized papers that have none; --rescore recomputes closest papers
import_guides	Copy the Markdown guides into the database
send_reactivation, suppress_emails, announce_tools	Account activation reminders, bounced addresses, announcement of new tools
