Browser-based viewer for Sanger sequencing chromatograms in AB1/ABIF and SCF format. Opens .ab1/.abi/.fsa files, shows raw and analysed traces, basecalls, quality values and the ABIF directory, and puts two reads side by side for comparison. Aligns a read against a reference sequence to highlight mismatches. Exports the read as FASTA, FASTQ or ABIF and the chromatogram as a high-resolution image. Runs entirely in the browser — files are never uploaded.

Browser-based tool to open almost any sequence file — FASTA, FASTQ, GenBank, EMBL, Swiss-Prot, AB1/ABIF, SCF, Clustal, Stockholm, PHYLIP, NEXUS, MSF, PIR and more — see every sequence inside, pick the ones you want, and save them as FASTA. The format is detected from the file content, not from the extension, so unlabelled or misnamed files still open. Runs entirely in the browser — files are never uploaded.

Browser-based viewer for GenBank and GenPept files. Renders an interactive linear and circular feature map, the annotated source text, and the nucleotide/protein sequence side by side. Translates CDS features using the record's own genetic code and translation qualifiers, flags where the stored /translation disagrees with a plain translation, and adds optional computed layers: ORF prediction and restriction-site mapping. Handles multi-record files. Runs entirely in the browser — files are never uploaded.
