Best Apps for Academic Writing & Research in 2025
The right app stack saves you hours every week. We tested the apps US college students actually keep on their phones and laptops past the first month.
For note-taking and writing: Notion and Obsidian dominate, with Apple Notes still surprisingly competitive for short essays. For PDF reading and annotation: Readwise Reader and LiquidText are the favorites among grad students. Citations: Zotero (free, open-source) beats EndNote on every metric except institutional integrations. For focused writing: iA Writer and Ulysses block distractions. AI assistants: ChatGPT Plus and Claude are general-purpose; Lex.page and Notion AI integrate inline. For research synthesis: Elicit and Consensus are game-changers, they search 200M+ papers and summarize findings. We recommend a 4-app core: Zotero + Notion + Readwise Reader + ChatGPT or Claude.
