The Side Roads
Specialists outside the Big Four. Worth knowing, not required.

This is the "nice to know" shelf. Not homework. Just options.

The Big Four get most of the attention, but there are smaller tools doing interesting things in specific lanes. None of these are essential for this course. But if you're curious — or if one of them scratches an itch the big names don't — it's worth knowing they exist.

The Interesting Ones

Perplexity
Research-first answer engine
Perplexity is built to show receipts. Ask it a question and you don't just get an answer — you get citations, links, and a trail showing where the information came from. Their Deep Research feature, upgraded in February 2026, runs on top-tier models for Pro users and goes deep on complex queries.
best for
When you want "show me the sources," not just "trust me."
the feel
Like a research librarian who never makes you feel dumb for asking.
Grok
xAI
Grok leans into current events and cultural energy, with creative features like the Grok Imagine API for video and audio workflows. It's powerful and capable, though it's worth noting that the platform has drawn some regulatory attention in certain regions. For our purposes: interesting to watch, useful for trend-flavored creative work.
best for
Trend energy. Creative media experiments. A "what's happening right now" flavor you won't get elsewhere.
the feel
The friend who's always three tabs deep in something you haven't heard of yet.
Pi
Inflection AI
Pi calls itself "personal AI" and means it. The whole design is built around warm, supportive conversation — not task completion. It's less about getting something done and more about thinking something through. The pacing is gentle. The tone is patient. It's the AI equivalent of a good listener.
best for
Warming up ideas. Reflection. Low-pressure brainstorming when you're not sure what you think yet.
the feel
Like talking to someone who has all the time in the world.
Poe
Quora
Poe is a switchboard. Instead of committing to one AI, you can run the same prompt through multiple models and compare the responses side by side. It's not a model itself — it's a multi-model playground. Useful for experimentation, especially when you're trying to understand how different tools think differently about the same question.
best for
Side-by-side comparisons. Experimentation. Seeing how the same input produces different outputs across models.
the feel
A tasting flight instead of committing to the bottle.

Open-Source Models

There's a whole world of open-source AI models you can download, customize, and run on your own hardware. Meta's LLaMA family is the most prominent, but there are many others. The trade-off: you get maximum control and privacy, but you're also doing the setup yourself.

For most people reading this course, this isn't the starting point. But if you're technically inclined — or you're building something proprietary where data control matters — it's worth knowing this lane exists.

Don't Get Overwhelmed

You don't need twelve tools. You need one main assistant, one clear project, and one habit of showing up.

Everything else becomes play. Try Perplexity for a research question. Run something through Poe to see how it compares. Use Pi when you just need to think out loud. But the real work happens when you pick one tool and go deep. For this course, that tool is Claude.

The side roads are nice to drive. The main road is where the work gets done.
