AI widgets: models, papers, repos, terms and subscriptions

These widgets live in the AI category of the library (AI; see also Notion AI widgets). They’re made for people who build with AI or use it every day — engineers, researchers, PMs, prompt tinkerers and anyone learning AI — and they’re all free.

Live data: models, papers and repos

Widget	Source	Refreshed	Options
Hugging Face Trending Models	Public Hugging Face API	About hourly	Trending / most liked / most downloaded (30 days), task (text generation, text-to-image, speech recognition…)
Latest arXiv Papers	Official arXiv API	Every 1–3 hours	Category (cs.AI, cs.CL, cs.LG, cs.CV…), keyword filter
New AI Repos on GitHub	Public GitHub search API	About every 3 hours	Topic (AI agents, LLMs, RAG, MCP…), period (this week / month / year / all time)

• The order is exactly what the source returns. We don’t score anything or build our own leaderboard, and we don’t show avatars or logos. Each widget shows its source and when it was updated.
• GitHub has no official “Trending” API, so this widget lists repos created in the chosen period, sorted by stars — and says so. “All time” sorts by total stars.
• The arXiv keyword filter looks through the latest 20 papers (a paper shows if any keyword appears in its title or abstract) and tells you when nothing matches. Thank you to arXiv for use of its open access interoperability.
• Model names, paper titles and repo descriptions are shown as published, untranslated. If a source can’t be reached, the widget says so instead of making anything up.

Learn a little every day

• AI Term of the Day: 52 common terms we wrote ourselves — tokens, context windows, RAG, agents, MCP, fine-tuning, LoRA, quantization, hallucination, evals and more — each explained in a sentence or two, with an example and a “Tomorrow” preview in the large size. Pick a category or pin a single term.
• Prompt Tip of the Day: 28 general techniques (state the goal, show examples, set the format, let it ask questions first, ask for just the changes…), with a before / after rewrite in the large size. Filter to coding, writing or analysis.
• Both rotate by date, so everyone sees the same one on a given day. They cover general practice and aren’t tied to any vendor’s model.

Subscriptions, costs and dates

• AI Subscriptions: enter each service’s name, price, monthly or yearly billing, and any charge date. The widget shows your monthly and yearly total, the split by type and the next renewal. Yearly plans count as ÷12 per month; enter every price in the same currency (no conversion). There’s a Hide amounts switch. The default items are generic samples, and no brand logos are used.
• Token Cost Calculator: enter input and output tokens per call, calls per day and each model’s price per 1M tokens to see the cost per call, per day and per month for up to 4 models side by side. Add a context window to see how much of it one call uses. No vendor prices are built in — the default “Sample model” entries and prices are samples, so enter real prices from the official pricing pages and recheck them now and then. In the large size you can drag Calls per day to try other numbers (not saved).
• AI Event Countdown: paper deadlines, launches, conferences, hackathons and talks, sorted by date with days to go, plus a 90-day timeline in the large size. The four defaults are made-up samples. Paper deadlines are often AoE (Anywhere on Earth), so enter the date in your own time zone.

100 Days of AI and My Data

100 Days of AI saves check-ins to your own My Data. In the editor’s Data section, click Create “100 Days of AI” and connect (or pick an existing habit table) — see Data section. Then tap Done for today each day; the widget shows the day you’re on, a 10×10 grid and your streak. You can only check in for today — edit past days in My Data.

• Study plan takes one line per day: line 1 is day 1’s topic. The default is a sample plan; replace it with your own, or clear it to hide topics.
• The default start date is a sample (counted back from today) — change it to the day you started.
• Check-ins count toward the usual daily limits: 20 a day on Free and 80 on Pro — see Limits & Pro.
