Perplexity
I’m a massive ChatGPT user, but I’ve started branching out, especially for research. And Perplexity is the one I keep coming back to.
Why? Every answer comes with real citations and links, so you’re never left guessing where the info came from (or if it’s made up). Unlike ChatGPT, it’s built from the ground up to search the web, and it does it fast.
I use it constantly for quick overviews, topic research, and fact-checking content I create: blog posts, newsletters like this one, even video scripts. It saves me time and gives me confidence the facts are solid (of course, you’ll need to do your own due diligence too).
It’s not my go-to for creative writing or tone-heavy tasks (e.g. coding) – ChatGPT and Gemini still shine there – but when I need accurate info quickly, Perplexity is always open in a tab.

AnythingLLM
Messing with local AI tools is usually a headache. You need Python, npm, weird CLI commands… and while that’s fun for a few oddballs, for most of us it’s a productivity killer.
That’s why I really like AnythingLLM. It installs like a normal desktop app, no coding, no setup drama. Once it’s up, it’s basically your own local ChatGPT, fully under your control. Also, you can use their paid cloud version.
You can plug in any major LLM via API: Claude, Gemini, ChatGPT, Mistral, Perplexity, and dozens more. But if you prefer to run everything locally? It works with open-source models too, via Ollama, Hugging Face, etc. Just fire it up, and you’re running a full AI assistant on your own machine (you'll need a decent computer for this).
But it goes further than just chatting. You also get access to more advanced building blocks like vector databases and embedders (that’s how your AI stores and 'remembers' knowledge). There’s RAG support, web scraping, web search, and a few other gems.
The real ChatGPT killer, though, is the Agent Flows builder. It lets you create custom AI-powered sequences for pretty much anything. For example, you could build an assistant that scrapes trending news and content and helps you write original social posts for your business.

Dify
Building AI workflows usually means juggling messy code, API calls, and cloud services – total chaos. But Dify flips that. It’s a no-code, visual builder that lets you create multi-step AI agents and workflows with logic, RAG support, and more.
You can plug in any LLM via API (OpenAI, Gemini, Claude, Mistral, Perplexity…) or run open-source models locally. It also includes vector databases, conditional logic, loops, parameter extractors, and more. You can even embed your custom workflows (like a custom chat agent) directly on your site or web app.
Use cases are endless: automate personalized email outreach, generate SEO audits, summarize research, or build an internal knowledge-base chat. Personally, I’m planning to use it to power a chatbot for our site’s internal resources – stay tuned for the results.
