Designed for Researchers
We built the tool we wanted for our own work. Every feature is designed to accelerate discovery and eliminate friction.
Large-Scale Ready
Don't be afraid of queries that return thousands of results. ProSeq is engineered to handle large data pulls without timeouts.
Privacy First
Your research is yours alone. We operate as a stateless proxy, meaning we never log or store your queries or results.
Instant Feedback
Get an instant preview of your data in the browser, so you can verify your query was successful before opening the file.
Frequently Asked Questions
What kind of queries can I use with QAIEDGE ProSeq?
You can use a wide range of Entrez queries, from simple terms like 'human insulin' to advanced queries combining fields, such as 'TP53[gene] AND Mus musculus[orgn] NOT (partial[title])'. The tool is designed to handle the same powerful query syntax as the NCBI website.
Is this service free and are there any limits?
Yes, QAIEDGE ProSeq is completely free to use. It acts as an intelligent interface to NCBI's public E-utilities API. While our tool imposes no limits, we ask users to be mindful of NCBI's usage policies, which recommend no more than 3 requests per second to avoid overloading their servers.
What is the FASTA format?
FASTA is a text-based format for representing nucleotide or peptide sequences. Each sequence in a FASTA file begins with a single-line description (header), followed by lines of sequence data. The header line is distinguished from the sequence data by a '>' symbol in the first column. Our tool provides this standard, analysis-ready format.
Is my research data private and secure?
Absolutely. Security and privacy are paramount. QAIEDGE ProSeq operates as a stateless proxy; we do not log, store, or analyze your queries or the resulting data. Each request is a direct, secure transaction with NCBI's servers, and the results are streamed directly to your browser for download.
