ChatGPT: strengths & weaknesses

Does almost everything: write, code, brainstorm, analyze images, create art with DALL-E
Voice mode works well for hands-free chatting on your phone
Custom GPTs let you build a personal assistant for specific tasks (e.g., travel planner, study buddy)
Large community means tons of tutorials and shared prompts
Can confidently give wrong answers (hallucinations) without warning you
Free tier limits access to the best model (GPT-4o) and features like image generation
No built-in citations—you have to fact-check on your own
Mobile app exists but some features (like file uploads) are clunkier than on desktop

Perplexity Spaces: strengths & weaknesses

Every answer comes with clickable sources—great for school, work, or fact-checking
Spaces keep your research organized and remember context across questions
Upload PDFs, CSVs, or code files and ask questions about them directly
Real-time web search means you get current info, not just training data
No image generation or voice output—it's text and citations only
Free tier limits how many Spaces you can create and how many queries you can run
Can still make mistakes on niche or very recent topics despite citations
No mobile app (you use the website on your phone, which works but isn't as smooth)

Common questions

Is ChatGPT better than Perplexity Spaces for writing a school essay?

For writing the essay itself, ChatGPT is better—it can draft, rephrase, and add creative flair. But if you need to include cited facts, use Perplexity to gather sources first, then ChatGPT to polish the text.

Can I use Perplexity Spaces on my phone?

Yes, through your phone's web browser. There's no dedicated app, but the mobile site works well for typing queries and reading answers. ChatGPT has a proper mobile app with voice mode.

Which tool is cheaper for a regular person?

Both have free tiers. ChatGPT's free tier gives you GPT-3.5 (slower, less capable) with limited GPT-4o access. Perplexity's free tier gives you limited searches and Spaces. For $20/month, ChatGPT Plus unlocks full GPT-4o, DALL-E, and more. Perplexity Pro ($20/month) removes limits and adds advanced features. Neither is clearly cheaper—it depends on which features you need.

Can I upload a PDF and ask questions about it in both tools?

Yes, both allow PDF uploads. In Perplexity Spaces, you upload files to a Space and the AI references them in all related questions. In ChatGPT, you can upload a PDF in a chat and ask questions about it, but the context resets if you start a new chat.

Which one is easier to start using?

Perplexity is slightly easier—you just type a question and get an answer with sources. ChatGPT also starts with a simple chat, but you may need to choose a model or adjust settings to get the best results. Both are beginner-friendly.

ChatGPT is the creative all-rounder; Perplexity Spaces is the research pro with citations—pick based on whether you need to make things or verify things.

If you want one tool that can write, draw, and chat about anything, start with ChatGPT—it's the most versatile. But if your work or studies depend on getting facts right with sources you can check, Perplexity Spaces will save you time and headaches. Both have free versions, so try them both for a week and see which fits your daily flow better.
