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 |
