Everybody lists out connectors like Gmail or Calendar like people don't know they exist. There remain much better and more useful connectors than those. So here is the list of the most underrated connectors in 2026:
1) LetsFG- Very important because it is annoying to manually search for tens of hotels + their hundreds of reviews before booking a hotel. I type: "Find 3 hotels in Lisbon for 4 nights, only me and my wife, and show me the total with every fee plus the cancel date. Ignore any hotel with consistent noise or customer service complaint." With reviews checking, Claude can also expose any hidden fees customer complained about.
2) AllTrails- If you are into hiking, this is really cool. It searches a huge trail database (500,000+ trails) for you. Ask it something like: "Find 3 easy hikes within 1 hour of Lisbon that are good for a Sunday morning with a dog, under 2 hours each, and tell me which one has the most shade." It is way more efficient than going through reviews manually yourself and wasting hours.
3) Consensus- It searches real scientific papers (200M+) and answers some complex questions with actual proven data. You can ask something like: "Does creatine actually help memory? Look at the studies and tell me what most of them say and how strong the evidence is." It is the first thing I use before I believe any scientific facts on the internet.
4) PubMed- This one is strongly about medical papers. You can ask: "Find the 3 most recent studies on intermittent fasting and sleep and tell me in plain words what they actually found." For medical stuff use PubMed, but for general information from any papers, use Consensus.
5) Legal Data Hunter- This one is incredible if you want any information about the laws. Works very well for normal people as well as for lawyers or law students. It reads the official laws and court rulings of 160+ countries (EU law included), so Claude quotes the real source and doesn't guess. You can ask: "My flight in Spain was cancelled. Find the EU rules on compensation and tell me what I can claim." Please be aware that it is a research tool, but not a lawyer.
