Open Claude. There are three buttons you probably walk past every day.
They are Extended Thinking, Web Search, and Research.
Three different jobs. The wrong button gets you the wrong answer. The right one cuts a 30-minute task to 30 seconds.
This post is the plain-English guide to when to hit each.
The 10-second rule of thumb
Thinking is for deliberation, search is for facts, research is for reports. That is the whole map you need.
Extended Thinking: when Claude should slow down
By default Claude responds quickly. Extended Thinking tells it: spend more time on this before answering.
You toggle Extended Thinking when the problem has three or more hard constraints, multiple steps, or more than one plausible answer. You want the considered version, not the fast one.
Three good Extended Thinking prompts
For chat prompts and quick answers, do not bother. Extended Thinking is for the deep ones.
Web Search: when Claude needs the internet
Claude was trained on data with a cutoff. Anything after the cutoff is invisible to it unless you toggle on Web Search.
You toggle Web Search when the answer depends on what happened recently, like today's stock price, this week's news, or the current pricing of a competitor.
Three good Web Search prompts
Ask Claude something current without Web Search on, and it will either guess from training data or tell you it does not know. Toggle it on. Source citations come back automatically.
Research: when you want a report, not an answer
Research is the longest-running mode. Claude searches, opens multiple sources, reads each, cross-references, and produces a structured synthesis. It is the closest thing in Claude to a junior analyst writing a brief.
You toggle Research when you want a 1-2 page document with multiple sources cited, not a one-paragraph chat reply.
Three good Research prompts
Research is slow, with five to ten minutes being normal, but you get back a structured document with citations. Treat it like a draft from a junior, not a finished product.
A comparison table
| Mode | When | Output shape | Time |
|---|---|---|---|
| Extended Thinking | Multi-constraint problems, design decisions | A considered reasoning answer | 30-90 seconds |
| Web Search | You need live information | An answer grounded in cited current sources | 10-30 seconds |
| Research | You want a report from multiple sources | A structured 1-2 page document with citations | 5-10 minutes |
A common mistake: combining them when you should not
People sometimes toggle on all three at once thinking they get the best of all worlds.
You do not. You get a slower answer that lands no better.
Pick the one that fits the job. Need facts AND deliberation? Do Web Search first to pull the facts. Then a follow-up message with Extended Thinking to chew on what you found.
Pairing modes with skills
We run you through these three modes side-by-side at our Claude Code workshop. Most operators only ever hit one of these three buttons before training; afterwards, picking the right one becomes automatic.
The step that compounds: a skill that knows when to recommend which mode.
We have a skill called research-brief that always runs in Research mode and outputs in our brief format. When we ask for "a competitor brief on X", the skill triggers, switches modes, and runs.
That is the operating-stack idea again. Skills 101 covers the foundation.
What to do next
Tomorrow morning, the first prompt you write: pause for two seconds. Pick the right mode for the job. Hit it.
Do that for a week. You will notice the difference in your answers.

Frequently asked questions
What is the difference between Extended Thinking, Web Search, and Research in Claude?
Thinking is for deliberation, search is for facts, research is for reports. That is the whole map.
Extended Thinking tells Claude to slow down on a hard problem. Web Search pulls live information from the internet. Research opens five or more sources and hands back a structured document.
When should I use Extended Thinking?
Turn it on when the problem has three or more hard constraints, four or five steps, or more than one plausible answer. Data model design, pricing-hole analysis, and architecture decisions all qualify.
For quick answers and everyday chat prompts, leave it off. You will just wait longer for the same reply.
Should I turn on all three modes at once?
No. People do this expecting the best of all worlds and get a slower answer that lands no better.
If you need facts and deliberation, split it. Run Web Search first to pull the facts. Then send a follow-up with Extended Thinking to chew on what came back.
How long does each Claude mode take?
Web Search returns in roughly 10 to 30 seconds. Extended Thinking takes 30 to 90 seconds. Research runs 5 to 10 minutes.
Research is slow because it is opening and cross-referencing multiple sources. Treat the output like a draft from a junior analyst, not a finished document.
Does Claude cite its sources when Web Search is on?
Yes, citations come back automatically. Ask Claude something current with search switched off and it will either guess from training data or tell you it does not know.
