Massive list of resources for PhD candidates and researchers

Writing a PhD thesis or a journal paper means using dozens of different tools, platforms, and services at every stage of your research. You need tools for finding the right journal, managing your references, checking for plagiarism, formatting citations, writing clearly, and building your researcher profile.

The problem is that most of these tools are scattered across the internet with no single place to compare them. You end up asking lab mates, scrolling through forum threads, and bookmarking things you forget about a week later.

This post brings together the most useful resources for PhD candidates and academic researchers in one place. Every tool listed here is either free or offers a free tier. Where a tool is paid, that is noted. The categories follow the typical stages of a research project, from selecting a journal through to building your visibility after publication.

Journal Selection Tools

Submitting your paper to the wrong journal is one of the most common and most preventable causes of rejection. The scope might not match, the impact factor might be too high or too low for your work, or the journal might have a six-month review cycle you cannot afford to wait through. Journal-matching tools help you find the right fit before you submit.

These tools typically work by matching your abstract or title against a database of journal profiles. You paste in your abstract, and the tool returns a ranked list of journals sorted by relevance. Some also show journal metrics, acceptance rates, and average review times.

Elsevier Journal Finder is one of the most commonly used. It covers all Elsevier journals and returns suggestions based on your abstract. Springer Journal Suggester does the same for the Springer Nature portfolio. JournalGuide is a free, publisher-neutral option that covers journals across multiple publishers, which makes it useful if you are not committed to a particular publisher. Manuscript Matcher by EndNote is another option, particularly useful if you are already using EndNote for reference management.

For a more detailed guide on the journal selection process, see our post on how to find the right journal for your research paper.

Professional Editing and Proofreading Services

If English is not your first language, professional editing is not optional. It is the difference between a clean submission that reviewers can focus on for content and a submission that gets flagged for language issues before anyone even reads the methodology.

PM Proofreading specialises in academic editing for non-native researchers. Every manuscript is edited by a subject-matter expert with a postgraduate degree in a relevant field. The service covers grammar, sentence structure, academic tone, coherence, logical flow, and formatting. Every order includes tracked changes and a free language editing certificate, which many journals require as proof of professional language editing.

PM Proofreading also offers thesis editing, AI humanizing, paraphrasing, citations and references adjustment, and language translation. View pricing here.

Other commercial editing services include Elsevier Language Editing Services and Edanz. Both are publisher-affiliated and offer language editing, though neither provides the free language editing certificate that PM Proofreading includes with every order.

Writing, Grammar, and Paraphrasing Tools

Grammar-checking tools are useful as a first pass before professional editing, but they should not replace a human editor. Tools like Grammarly catch surface-level errors (missing articles, subject-verb agreement, punctuation), but they struggle with the nuances of academic writing: field-specific terminology, complex sentence structures, and the logical flow between paragraphs.

Grammarly is the most widely used. The free tier covers basic grammar and spelling. The premium version adds tone, clarity, and vocabulary suggestions. Ginger and WhiteSmoke are alternatives with similar feature sets.

For paraphrasing specifically, LLM-based tools like ChatGPT and Claude can help you rephrase sentences, but the output needs careful review for accuracy and tone. If your university uses Turnitin, be aware that paraphrased text can still trigger AI detection flags. PM Proofreading’s academic paraphrasing service combines AI-assisted rewriting with human expert review to ensure the final text reads naturally and passes both similarity and AI detection checks.

For a deeper discussion on using LLMs effectively as a researcher, see our LLM prompting guide for researchers.

Plagiarism Checkers

Running a plagiarism check before submission is good practice, even if you are confident in the originality of your work. Accidental similarity happens more often than you would think, especially in literature reviews where multiple papers describe the same foundational concepts using similar language.

Turnitin is the industry standard. Most universities provide institutional access, and many journals use it during the editorial process. If your institution gives you access, use it. Copyleaks is a solid alternative with both plagiarism and AI content detection. PaperRater offers a free tier with basic similarity checking.

If you receive a high Turnitin similarity score, our guide on how to reduce your Turnitin similarity score walks through the most common causes and how to fix them. If you receive a high AI detection score, see our guide on how to reduce your Turnitin AI score.

Citation Styles

Getting your citations wrong is one of the fastest ways to annoy a reviewer. Each journal specifies a citation style, and you are expected to follow it precisely. The four most common styles in academic research are APA, Chicago, MLA, and AMA, though many journals have their own house styles.

APA (American Psychological Association) is the most common in the social sciences, education, and psychology. The current edition is APA 7th. Chicago Manual of Style is widely used in the humanities and history. It has two systems: notes-bibliography and author-date. MLA (Modern Language Association) is the standard in literature and language studies. AMA (American Medical Association) is the standard in medical and health sciences.

For a comprehensive guide on citation formatting, including common mistakes and how to avoid them, see our complete guide to academic citations and references. If you need your citations adjusted to match a specific journal’s style, PM Proofreading offers a citations and references adjustment service.

Reference Management Software

If you are managing more than 20 sources manually, you are wasting time. Reference managers store your sources, generate in-text citations, and format your reference list automatically. They also save you from the nightmare of manually switching citation styles when a journal rejects your paper and you need to reformat for a different one.

Zotero is free, open-source, and widely considered the best option for most researchers. It works with Word, Google Docs, and LibreOffice, and it has a browser extension that lets you save sources directly from journal websites. The community-maintained citation style library covers virtually every journal. Mendeley is another popular free option, particularly strong for its PDF annotation features and its integration with Elsevier’s journal ecosystem. EndNote is the most feature-rich option but is paid (many universities provide institutional licences).

Other options worth considering: JabRef is a free, open-source manager that works well with LaTeX. Citavi combines reference management with knowledge organisation and task planning, making it a good choice for large thesis projects. Papers (ReadCube) is popular among Mac users for its clean interface and PDF management.

Building Your Researcher Profile and Visibility

Publishing your paper is only half the job. The other half is making sure people can find it. A strong researcher profile increases the discoverability of your work, makes it easier for collaborators to find you, and is increasingly important for grant applications and career progression.

ORCID is essential. It is a persistent digital identifier that links to all your publications, grants, and affiliations. Many journals now require an ORCID iD at submission. If you do not have one, create it today. It is free and takes two minutes.

Google Scholar profiles are automatically generated when Google indexes your publications, but you should claim yours and keep it updated. It tracks citations and calculates your h-index, which is one of the most commonly referenced metrics in academia. ResearchGate is a social network for researchers. It lets you share full-text papers (where copyright permits), ask and answer questions, and connect with researchers in your field. Academia.edu serves a similar function, though ResearchGate is generally more active in STEM fields.

Do not neglect your university’s institutional repository. Depositing your work there improves its visibility in Google Scholar and ensures it is accessible even if you change institutions.

Academic Research Databases

These are the databases you will use daily for literature searches. Which ones you rely on depends on your discipline.

Google Scholar is the broadest. It indexes articles, theses, books, conference papers, and preprints from almost every discipline. It is a good starting point, though it includes a lot of grey literature and does not filter by quality. Scopus (Elsevier) and Web of Science (Clarivate) are the two most important curated databases. Both index peer-reviewed journals and provide citation metrics. If your institution provides access, use both. They index different journals, so searching only one means missing papers.

PubMed is the go-to database for biomedical and life sciences research. IEEE Xplore covers electrical engineering, computer science, and related fields. ScienceDirect hosts full-text articles from Elsevier journals.

When conducting your literature search, having a systematic approach matters. For guidance on how to structure a comprehensive search strategy, see our post on how to conduct a systematic literature review.

AI Writing and Research Tools

AI writing tools have become part of the researcher’s workflow, whether for drafting, summarising literature, or brainstorming. The key is using them responsibly. Most universities now have AI use policies, and journals are beginning to require disclosure of AI assistance in manuscripts.

The three major general-purpose LLMs are ChatGPT (OpenAI), Claude (Anthropic), and Gemini (Google). All three can summarise papers, help with brainstorming, draft outlines, rephrase sentences, and explain difficult concepts. Our LLM prompting guide for researchers covers how to write effective prompts for each of these tools.

More specialised tools are emerging as well. Consensus searches the academic literature and provides AI-synthesised answers backed by peer-reviewed papers. Elicit helps you extract data from papers and build structured literature reviews. SciSpace (formerly Typeset) helps with formatting manuscripts to journal specifications.

One important caution: AI-generated text can trigger Turnitin’s AI detection. If you use AI tools in your writing process, it is important to substantially rewrite and verify the output. PM Proofreading’s AI humanizing service rewrites AI-generated academic text to read naturally while preserving your original meaning.

Conclusion: Build Your Toolkit Early

The best time to set up your research toolkit is at the beginning of your PhD, not the night before submission. Create your ORCID profile. Set up a reference manager. Bookmark the databases relevant to your field. Familiarise yourself with the plagiarism checker your university uses. These are small investments of time that pay off over years of research.

And when your manuscript or thesis is ready for submission, invest in professional editing. It is the final quality check that catches the errors you cannot see after months of staring at the same text.

Frequently Asked Questions

What is the best free reference manager for PhD students?

Zotero is widely considered the best free option. It is open-source, works with Word and Google Docs, has a browser extension for saving sources directly from journal websites, and supports virtually every citation style through its community-maintained style library. Mendeley is another strong free option, especially if you publish in Elsevier journals. The best choice depends on your discipline and workflow, but Zotero is the safest default for most researchers.

How do I choose the right journal for my research paper?

Start with journal-matching tools like Elsevier Journal Finder, Springer Journal Suggester, or JournalGuide. These compare your abstract against journal profiles and return ranked suggestions. Beyond the tool results, consider the journal’s scope, impact factor, acceptance rate, average review time, and whether it is indexed in Scopus and Web of Science. Also check whether the journal requires a language editing certificate, and whether it charges article processing fees. For a step-by-step approach, see our full guide to finding the right journal.

Do I need a plagiarism checker before submitting my paper?

Yes, it is strongly recommended. Even if you have written everything in your own words, accidental similarity can occur in literature reviews and methodology sections where standard terminology is used. Running a Turnitin or Copyleaks check before submission lets you identify and address any issues before the journal does. Most universities provide institutional Turnitin access. If your score is high, see our guide on how to reduce your Turnitin similarity score.

Should I create an ORCID profile as a PhD student?

Absolutely. ORCID is a persistent digital identifier that links to all your publications, grants, and institutional affiliations. Many journals now require an ORCID iD at submission. Creating a profile takes about two minutes and is free. Even if you have not published yet, setting up your ORCID early means your first publication will be linked automatically. It also helps prevent name confusion with other researchers who share your name.
