What is included

From sequence preparation to results.

A desktop toolkit for researchers, bioinformaticians, and educators working with biological sequences. Choose the app that matches your input and scientific question.

Compare sequences

Inspect alignments and run pairwise DNA or protein alignment workflows.

Analyze DNA and proteins

Work with DNA statistics, ORF finding, codon usage, CpG islands, and sequence-derived protein properties.

Explore primers and restriction sites

Use primer mapping, PCR products, restriction digestion, and primer statistics tools.

Prepare sequence files

Translate, reverse-complement, extract ranges or windows, and split or merge FASTA records.

Generate and transform sequences

Create synthetic DNA or protein examples, mutate or shuffle sequences, and sample sequence regions.

Keep work organized

Use single-sequence and batch workflows, revisit saved analyses, and export results in the formats provided by each app.

Before you buy

Scope and requirements

Which system is this download for?

This release is a Windows 64-bit desktop installer with an English-language interface. This purchase does not provide a macOS or Linux installer.

Does sequence processing run locally?

Sequence processing runs locally in the desktop application. Buying and downloading require an internet connection. The installer may also download Microsoft Edge WebView2 if that runtime is missing, so installation is not guaranteed to be fully offline.

Do I need a subscription or an activation key?

No. This purchase is a one-time payment for the downloadable installer. Seqqio does not require an activation key.

Does every app accept every kind of sequence?

No. Each app has its own input alphabet, workflow, and limits. Choose a DNA, RNA, or protein workflow according to the tool's stated requirements. Sequence-derived estimates must be interpreted in the context of the method and your research question.

Where can I ask a question before purchasing?

Contact BioChemIntelli with your operating system and intended workflow. Do not send confidential research sequences or payment-card details.
