Anthropic is giving free API credits for university students
With the amount of money I’m spending on Claude Code, I may just need a student loan. 😆 Does this count, Anthropic? 🙏 More on reddit.com

Do I need to pay for both Claude and Anthropic to use the API key?
When making a complaint, please make sure you have chosen the correct flair for the Claude environment that you are using: i.e Web interface (FREE), Web interface (PAID), or Claude API. This information helps others understand your particular situation. try to include as much information as possible (e.g. prompt and output) so that people can understand the source of your complaint. be aware that even with the same environment and inputs, others might have very different outcomes due to Anthropic's testing regime. be sure to thumbs down unsatisfactory Claude output on Claude.ai. Anthropic representatives tell us they monitor this data regularly. I am a bot, and this action was performed automatically. Please contact the moderators of this subreddit if you have any questions or concerns. More on reddit.com

Are you using the web interface or the API?
Depends on what you're using it for. I use the API exclusively myself, I usually write a small utility Python script for any LLM tasks I'm going to do more than a couple times. More on reddit.com

Is Claude API cheaper than chat for heavy usage? Need project/knowledge base management
Can't exactly comment on if it will be cheaper, but the API tends to be the go-to for most advanced users. I'd recommend signing up for the API and playing around in the workbench; you'll see how the Project user interface was built. I wound up using both; too many things are too simple on the website to just hammer out and come back to later. There are absolutely desktop/web programs that do more advanced user interfaces, but I'm still learning about these and trying them myself. Most of the chatbot interfaces have project-like capabilities, plus more. Some of the tools are full knowledge management applications, so scroll through all the categories. There's a github project that tracks this stuff: https://github.com/openbestof/awesome-ai More on reddit.com
