## Executive GIST (TL;DR)
- The authors present **Helix Design Studio**, an open-source web application for analyzing and designing peptide sequences on an assumed α-helical scaffold. - The platform evaluates sequence compatibility with multiple membrane and solvent environments using a published environmental scoring framework. - The scoring framework combines intrinsic helix propensity, residue-pair interactions, electrostatics and hydrophobic exposure to produce environment-specific scores. - A sequence-dependent alignment rule links an amphipathic residue pattern to interfacial geometry during both analysis and optimization. - Users can inspect individual score contributions, generate candidate families and search for sequences that prefer a target environment or balance compatibility across environments. - Computational demonstrations in the preprint show that environmental assumptions and helix orientation change candidate rankings and sequence selection. - The authors report agreement between their implementation and an independent descriptor implementation, and they performed exhaustive enumeration for a tractable sequence space to support computational consistency. - Downloadable sequences, scores and calculation settings are available to provide reproducible starting points for simulation and experimental follow-up. - The authors emphasize that the scores assess model compatibility only; the tool does not predict folding equilibria or establish biological selectivity. - The web application and source code are freely available at the project site and via a linked GitHub repository; the preprint includes supplementary material and external data/code links.

This creates a design challenge: improving compatibility with a target environment can also favour interactions under conditions where activity is undesirable. Helix Design Studio is an open-source web application that addresses this challenge by analysing and designing peptide sequences on a prescribed α-helical scaffold. A published environmental scoring framework combines intrinsic helix propensity, residue-pair interactions, electrostatics and hydrophobic exposure to evaluate the assumed helical state in idealized solvents and interfacial environments. A shared, sequence-dependent alignment rule links the amphipathic residue pattern to the interfacial geometry during both analysis and optimization. Users can inspect score contributions, generate candidate families and search for sequences that favour a target environment or balance compatibility across environments. Computational demonstrations show that environmental assumptions and helix orientation affect candidate rankings and sequence selection. Agreement with an independent descriptor implementation and exhaustive enumeration of a tractable sequence space support computational consistency. Downloadable sequences, scores and calculation settings provide reproducible starting points for simulation and experimental characterization. The scores assess model compatibility; they do not predict folding equilibria or establish biological selectivity. Helix Design Studio is freely available at https://helix.simbioslab.com/. Scientific Contribution. Helix Design Studio connects sequence analysis and candidate generation with explicit design objectives across solvent and interfacial environments. An interpretable scoring framework supports diverse peptide families, preferences for a target over competing environments and compromises between conditions; downloadable sequences, scores and calculation settings make the design choices reproducible. ### Competing Interest Statement The authors have declared no competing interest. ## Footnotes * ## Funder Information Declared Agencia Estatal de Investigación, PID2022-141534OB-I00 Xunta de Galicia, ED431C 2025/15, ED431G 2023/03 European Regional Development Fund, PID2022-141534OB-I00 Ministerio de Universidades, FPU22/00636 Copyright The copyright holder for this preprint is the author/funder, who has granted bioRxiv a license to display the preprint in perpetuity.
