Trust + time weighted: +64%
AI summary — not a quote
Claude is highly regarded by users for its ability to handle complex, multi-part instructions and long-form document analysis. It is frequently used for specialized tasks like certification study prep, UI/design coding, and contract review. While praised for a more natural and less rigid 'disposition' compared to other models, users frequently note that it struggles with mathematical accuracy and can be overly agreeable, sometimes validating a user's flawed premises rather than correcting them.
Pros
- Excellent at following complex, multi-step instructions without dropping details.
- Strong performance in coding tasks, particularly UI/Design and Blazor.
- Effective at synthesizing long documents into 'living' study guides or summaries.
- Nuanced, natural-sounding outputs attributed to its values-based training.
Cons
- Unreliable for mathematical calculations and spreadsheet formulas; prone to hallucinations in these areas.
- Usage limits on the paid tier can be reached quickly during intensive sessions.
- Tendency to be a 'cheerleader,' validating incorrect user assumptions instead of providing objective corrections.
- Occasional inaccuracy in interpreting screenshots or specific UI elements in images.

Use for manipulating data and modifying values and spreadsheet calculation formulas? No way. LLMs are so bad at math in general that I could not rely blindly on the output of an AI tool, I would have to verify each cell manually anyways afterwards that the value has not been hallucinated.
vibecoders who have decided that a community of photographers is a captive audience for whatever app they Claude-coded into existence over the weekend.
Yeah..... XML tags aren't new. They are known to work very well for other models (Claude, especially).
I have the exact opposite experience with Claude almost daily. It starts explaining something it is doing, and it mostly makes sense, but it is also...I don't know, a little stupid. It's not doing the thing in an optimal or smart way. I proceed to ask why it did/did not do it one way, and it chonks through its "oh wow, you made me rethink this, and now it's much better than what I was doing, and here is why" response, cleans up the workflow, and redoes it better.
for most things that don't involve changing something on the phone I use Claude.
Perplexity AI
48 positive (66%) · 19 mixed (26%) · 6 negative (8%)
Trust + time weighted: +61%
AI summary — not a quote
Perplexity AI is frequently described as a "research powerhouse" that functions as a hybrid between a search engine and a large language model. Users value its ability to provide cited summaries, data visualizations, and niche news discovery, often using it to replace traditional Google searches. While highly regarded for academic and professional research, it is commonly used as part of a multi-AI workflow alongside tools like ChatGPT and Claude rather than as a total replacement.
Pros
- Excellent for deep research, providing cited sources and structured summaries.
- Offers data visualizations, charts, and graphs that many other LLMs lack.
- Effective for exam preparation and generating practice questions for certifications like CISSP and Azure.
- Includes a 'Spaces' feature for organizing research by specific topics.
Cons
- Susceptible to system prompt leakage through specific language-based bypasses.
- Users report occasional inaccuracies, sometimes requiring 'arguments' with the AI to reach the correct answer.
- Some users find it less effective for live data grounding compared to competitors like ChatGPT.

Perplexity has spaces.
Wow. I copy/pasted your prompt into Perplexity and the assessment it gave of me made so much sense... Its understanding of "me" is spot-on. I got back pages and pages of how I like to communicate, how it should communicate with me... And all of it says a lot about who I am as a person.
Perplexity is good for this kind of stuff I think. That’s the only use case of that model
Pro Tip: For bleeding-edge sectors, run this prompt in a model with active web search enabled (such as ChatGPT Search, Perplexity, or Gemini) so the chronological citations are pulled from live data.
