The definition of 20€ well spent? This.
If you tried Claude and didn't like it, you weren't using it right.
It's not another ChatGPT. It has a learning curve. But once you get these features, you won't go back.
Here's exactly how to use each one 👇
BTW and before we dive into the various features — I'm speaking live this week 🎤
For those of you who haven't seen it yet, I'll be joining the Palau Community for a free live workshop this Thursday, May 7th, 15:00–16:00 CEST. We'll be getting into real AI × Sustainability workflows, the hard questions nobody is answering clearly, and yes — there's a small surprise at the end. If you're free, come hang. Registration link is right here: https://palau-community.circle.so/communications-live-session-9c9aec
💬 𝐂𝐥𝐚𝐮𝐝𝐞 𝐂𝐡𝐚𝐭 This is your regular interface, think ChatGPT but it actually reads what you give it.
→ Go to claude.ai → Start chatting → Switch to Opus 4.6 + Extended Thinking for anything complex
That's it. Same entry point as any chatbot. Just smarter with context.
🖥️ 𝐂𝐥𝐚𝐮𝐝𝐞 𝐂𝐨𝐰𝐨𝐫𝐤 A colleague who has access to your actual files, no uploading, no copy-pasting.
→ Download the Windows or Mac app → Slide the toggle at the top to Cowork mode → Grant access to a folder → Type your prompt and let it work
Point it at your supplier questionnaire folder. Ask for an emissions overview.
Done.
📁 𝐂𝐥𝐚𝐮𝐝𝐞 𝐏𝐫𝐨𝐣𝐞𝐜𝐭𝐬 Your saved workspace, every chat already knows your context.
→ Go to claude.ai → click Projects → create one per deliverable → Upload your files as a knowledge base (reports, templates, briefs) → Every new chat inside inherits everything
One project for Decarbonization. One for your LCA. Never explain yourself again.
⚙️ 𝐂𝐥𝐚𝐮𝐝𝐞 𝐒𝐤𝐢𝐥𝐥𝐬 That intro you copy-paste every session? Build it once. Never type it again.
→ Go to your Customize on your side panel→ click Skills → Write your context once: your industry, role, reporting scope, tone → Claude reads it automatically at the start of every chat, if you trigger it.
We always talk about how important context is, yet most of the time we get lazy to type the same context again and again. Well Claude did solve that already. If you find yourself writing the same context more than once, you built it as a skill.
