DevCache от Ranjeet Singh

DevCache is for interview prep you actually finish.

You solve a LeetCode problem. It is Accepted. You mean to push it to GitHub, write a note, and revise later. Then the next problem shows up. DevCache does that follow-up.

LeetCode
Submit as usual. After Accepted, the solution is saved, explained, and committed to the GitHub repo you pick. The original accepted code is kept as-is. A cleaner follow-up solution can be stored separately.

Topics
Pages are not summarized automatically. Open an article you want to keep, click Summarize this page, and it becomes a topic you can reopen later.

Notes
Short reminders and interview prompts next to the problems and topics you already studied.

Interview questions
Questions are generated from your saved topics, so revision is based on what you read, not a random list.

How it works
Sign in with GitHub in the popup. Point the add-on at your DevCache server, choose a repo, and pick an AI provider (Groq, OpenAI, Gemini, or Grok). You need an API key for summaries and writeups.

Data
DevCache sends page URLs, page or LeetCode content you choose to save, and GitHub sign-in to your DevCache backend so it can store solutions, summaries, and notes. It does not summarize every site in the background.

Requires Firefox 140 or later.
