Both rely on the power of language models to transform academic research, but their philosophy, architecture, and functionalities define specific uses. In this technological duel, how do you choose the ideal tool that will boost your productivity while ensuring optimal scientific rigor? This article details the strengths and limitations of Perplexity and Elicit to best support your research work in a digital era where artificial intelligence proves indispensable.

Two artificial intelligences with distinct targets: understanding the basics of Perplexity and Elicit

Perplexity AI and Elicit embody two different visions of AI-based research tools, adapted to varied uses in the academic field. While the stated goal is similar — to facilitate access to a vast amount of information by automating documentary synthesis — the method employed diverges profoundly.

Perplexity acts more like a search engine endowed with advanced natural language understanding. Its algorithm scans the web in real time to extract relevant data and provide conversational answers accompanied by clear and accessible citations. This approach makes the tool particularly effective for general or exploratory queries, covering a very broad spectrum of information, whether from scientific sources, press articles, or open databases.

Elicit, on the other hand, more specifically targets the academic and scientific domain. Its engine focuses exclusively on verified and recognized databases, such as PubMed or arXiv, thus restricting its scope to validated publications overseen by the scientific community. This focus offers increased precision, essential for work requiring a high degree of bibliographic reliability and rigor in source selection.

These nuances are essential because the very nature of the data exploited influences the granularity, relevance, and clarity of the results produced. A student seeking a quick yet comprehensive synthesis will often favor Perplexity, whereas an experienced researcher keen to support their writings with rigorously validated publications will prefer Elicit.

The distinction also relies on how these tools handle sources. Transparency is a key criterion: Perplexity presents a browsable list of references directly included in the responses, reinforcing the dialogic and intuitive aspect for the user. Elicit structures its scientific citations into precise tables, ensuring traceability and verifiability of information within a strict academic framework.

This dual approach can be seen as complementary and illustrates the different expectations in scientific research in 2025. Thus, the selection of an AI tool will mainly depend on the usage context, the user’s level of expertise, and their primary objective, whether it is rapid exploration or in-depth analysis of a specialized corpus.

At the heart of the effectiveness of any AI research tool lies its ability to integrate and update reliable data. In this domain, Perplexity and Elicit exploit specific technical architectures that mark their differences while ensuring performance and relevance.

Perplexity AI stands out by scanning the web in real time, allowing it to continuously index a vast amount of documents. Thanks to this ongoing monitoring, the tool can integrate the latest publications or online information very quickly, sometimes in less than 24 hours. This reactivity is particularly valued in dynamic fields where data evolve rapidly, providing a significant advantage for research that needs to be at the forefront of scientific or technical news.

In parallel, Elicit relies on targeted and structured monitoring. Integration of major scientific databases such as PubMed and arXiv enables the tool to ensure maximum reliability through formalized academic indexing. Updates remain regular and controlled, favoring quality over quantity, which is essential for rigorous research work requiring a solid foundation of validated publications.

The ability to distinguish core documents from secondary sources is another technical specificity to highlight. Elicit’s algorithms are optimized to prioritize scientific information, for example by identifying peer-reviewed journal articles or major publications in the field, whereas Perplexity favors a broader spectrum with less granularity in critical evaluation of texts.

These technical distinctions have a major impact on the relevance and use of the results obtained. They shape different experiences: one oriented towards broad and rapid exploration, the other towards more precise and exhaustive analysis of specific academic corpora. For illustration, a medical research laboratory will favor Elicit for its rigorous syntheses, while a student preparing a multidisciplinary state of the art will opt for Perplexity.

Characteristic	Perplexity AI	Elicit
Main sources	Real-time web, diverse content	Specialized scientific databases (e.g., PubMed, arXiv)
Data update	Continuous scan, rapid indexing (under 24h)	Regular updates of validated and controlled corpora

These technical particularities partly explain why some users prefer one tool over another. The nature of the data, access speed, and depth of analysis are all parameters to consider according to usage contexts and academic research requirements.

Ergonomics and user experience: the impact of the interface on academic research productivity

One often overlooked lever in choosing an AI tool dedicated to academic research is the user experience. Ergonomics deeply influence the speed, fluidity, and quality of information gathering, all essential elements to optimize productivity.

Perplexity offers a clean, intuitive interface centered on conversational exchanges. This ease of use facilitates the formulation of complex questions in natural language, making the tool accessible both to students and professionals who do not necessarily have advanced technical training. The answer is presented as a dialogue, enriched with explicit citations, which helps understand the reasoning behind each result.

In contrast, Elicit relies on a more modular interface oriented towards structured research management. Thanks to features dedicated to creating summary tables from multiple documents, the user can detail and refine each step of their scientific process. These tools are particularly suited to researchers who wish to rigorously follow a methodological protocol and efficiently exploit large volumes of data.

Here is a list of features that differentiate these two platforms ergonomically:

• Perplexity: smooth navigation, instant answers, conversational mode, quick source access via links, optimized for natural language queries.
• Elicit: advanced filters, thematic classification, exportable tables, duplicate management, modular organization of scientific data.

Customization of queries is also a determining criterion. Perplexity allows free phrasing with almost immediate access to structured responses, ideal for exploratory or preliminary needs. Elicit offers a range of refined filters — Boolean, date, scientific domains — enabling fine selection of relevant publications according to detailed academic criteria.

These differences define distinct uses. A student conducting documentary research will gain speed with Perplexity, while a doctoral student in the bibliographic analysis phase will benefit from Elicit’s advanced tools to structure documents and extract solid syntheses.

Data integration and export: optimizing the scientific research workflow

In academic work, the ability to export, modify, and integrate collected data into a research workflow is a key point for productivity. This is where Perplexity and Elicit offer different approaches that meet specific needs.

Perplexity favors direct sharing of sources via internet links, which facilitates quick exchange and access to original documents. However, this method remains limited for in-depth integration into bibliographic managers or scientific writing software. The lack of standardized metadata formats makes reference handling less automatic.

On its side, Elicit offers full export of results in CSV table form. This format is easily usable in bibliographic management tools such as Zotero, Mendeley, or EndNote. The structured export includes critical metadata — author, title, journal, date — allowing clear organization and precise tracking of references.

This difference has a tangible impact on how researchers build their bibliography and organize their documentary monitoring:

• Perplexity is more suited for quick consultation and informal sharing of accessible information.
• Elicit favors rigorous management and integrated exploitation within a formalized scientific workflow.

The APIs offered by the two platforms reinforce this distinction. Perplexity provides a simple API for consultation queries, ideal for developers wishing to quickly integrate searches into applications or monitoring processes. Elicit offers an API more dedicated to automated research pipelines, enabling systematic analysis of large corpora and their use in data science.

To maximize productivity, combining the strengths of both tools according to specific needs and project stages often constitutes the best strategy.

Data security and confidentiality: a crucial issue for sensitive academic research

Handling confidential or sensitive information is a major reality in the world of scientific research. Data security deals not only with the protection of consulted sources but also with the confidentiality of ongoing queries and works. In this context, the approaches adopted by Perplexity and Elicit differ.

Perplexity retains the search history, which allows improving the relevance of answers over time. However, this data management may raise confidentiality concerns when users work on sensitive or exclusive projects. To mitigate these risks, security protocols such as AES 256-bit encryption are used to protect exchanges, but the recording of queries remains a potential drawback for some researchers.

Elicit, on the other hand, applies rigorous measures regarding confidentiality. Queries are encrypted, data storage is limited, and the entire system prioritizes security to ensure that users’ works cannot be exploited by third parties. This makes Elicit a preferred choice for academic institutions where confidentiality is imperative.

For researchers, the question of data security directly influences their choice of working tool. Often, students or professionals in an exploratory phase opt for Perplexity, while laboratories, universities, and advanced research teams turn to Elicit.

This differentiation has become an essential decision-making criterion in 2025, as compliance with GDPR standards and best practices for managing scientific data become established in the global academic landscape.
