Bioinformatics Utility Belt
A curated suite of fast, serverless tools for everyday sequence analysis. Zero upload, zero latency, 100% privacy.
Reverse Complement
Compute reverse complements for DNA/RNA sequences with full IUPAC ambiguity code support, entirely in your browser.
Translate Nucleotides to Protein
Translate DNA/RNA to protein in all reading frames using the standard genetic code, or extract the longest ORF.
GC Content Calculator
Calculate nucleotide composition and GC% for raw or multi-FASTA input, one record per line.
FASTQ to FASTA Converter
Convert FASTQ blocks to FASTA format. Removes quality scores and keeps headers. Supports files up to 20MB.
K-mer Counter
Count frequency of substrings (k-mers) in your sequences. Useful for complexity analysis and motif finding.
Motif Finder
Find degenerate nucleotide patterns such as TATAWA or NGG using standard IUPAC ambiguity codes.
DNA↔RNA Converter
Convert between DNA (T) and RNA (U) notation with an auto-detect option and full FASTA support.
FASTA Formatter & Cleaner
Clean, wrap, and normalize FASTA sequences. Remove whitespace, enforce uppercase, and validate characters.
