Tendril — AI Lessons for Real Life

Tendril

The big idea

A chatbot answers your question. An AI AGENT does a task — it can browse the web, click buttons, write and run code, and call other AI as tools, all in a loop until it finishes. Examples: Cognition's Devin (autonomous software engineer), OpenAI's Operator (browses the web for you), Anthropic's Computer Use (controls your screen). Agents are the next step from chat: you give a goal, the agent figures out the steps. They are still unreliable for complex tasks but increasingly real, and they are reshaping what 'using AI' means.

Some examples

OpenAI Operator can book a restaurant reservation for you — gives goal, opens OpenTable in a browser, fills the form, confirms.

Cognition Devin writes pull requests on GitHub end-to-end; it's used by some startups for routine bug fixes.

Anthropic's Computer Use API lets a developer build an agent that controls a virtual desktop — same idea, more general.

Reliability today: agents work ~70% of the time on simple tasks, ~30% on complex ones — they need supervision, not blind trust.

Try it!

Try ChatGPT's 'Tasks' or any Custom GPT that uses Code Interpreter. Ask it to do something multi-step (analyze a CSV, browse the web, then summarize). Watch it loop. That's the agent pattern.

What is the main idea of "What an 'AI Agent' Actually Is (and How It's Different From a Chatbot)"?

Devin, Operator, Computer Use — agents act, not just chat. The shift that defines 2026 AI.
Use AI as the final authority for the whole decision
Avoid checking the answer once it sounds polished
Focus only on speed instead of judgment

Which use of AI fits this topic best?

Let the AI decide what matters without your review
Use the answer before checking whether it fits the situation
OpenAI Operator can book a restaurant reservation for you — gives goal, opens OpenTable in a browser, fills the form, confirms.
Use the first answer without checking it

What should a careful learner remember about "The rule"?

Use AI to draft or organize ideas about AI agent, then verify before acting.
Skip the context so the tool can guess faster
Treat the output as private even after sharing it online
Use the answer without checking the source

You want to use AI after this lesson. What is the safest next step?

Act immediately because the AI answer is written clearly
Use the AI answer as a draft, then check it against a reliable source.
Hide uncertainty so the final answer looks cleaner
Use private or sensitive details before checking permission

How should AI output about AI agent be treated?

As proof that no other source is needed
As a replacement for context, consent, or expert review
As a draft or helper output that still needs human judgment and verification
As something that becomes correct when it sounds confident

Name one way to verify an AI answer about AI agent.

Which action would help you apply "What an 'AI Agent' Actually Is (and How It's Different From a Chatbot)" responsibly?

Use the tool to avoid thinking through the tradeoff
Keep going even if the output conflicts with a trusted source
Use the first answer without checking it
