Engineering Workspace

Olto runs as one app with two labs. From the workspace picker (first run, or the ⌘K palette → “Switch workspace”) you choose Life Sciences or Engineering, and the navigation, terminology, AI framing, and accent adapt. Everything you create stays put; switching is purely a view change, persisted to your profile.

The engineering tools are deterministic and fully client-side: every result shows its governing formula or standard, runs in your browser, and is unit-tested against the published worked example. There is no AI anywhere in the numbers, and nothing here is metered.

Calculators

32 calculators across mechanical, structural, electrical, signals, and thermal/fluids — stress & strain, beam deflection, buckling, shaft torsion, gear ratios, IPC-2221 trace width, Ohm’s law, LC/RC, the 555 timer, Reynolds number, heat conduction, and more. Each names its standard or formula and is grouped by discipline.

Tolerance, BOM & references

Tolerance Stack-Up computes the 1-D worst-case (arithmetic) and RSS (statistical) resultant of a dimension chain, checks fit against a requirement with a Cpk estimate, and ranks which dimension drives the variation. The BOM Builder nests lines into sub-assemblies, rolls quantities up through every parent, totals cost and mass, and imports/exports CSV. The Materials reference (26 materials) and Fasteners & Threads tables (metric ISO + imperial UNC/UNF) cover the everyday lookups, and the Unit Converter spans length, force, pressure, torque, energy, power, flow, velocity, angle, and temperature.

Metrology & quality

Measurement Uncertainty (GUM) builds an uncertainty budget — combine rectangular, triangular, U-shaped, and normal sources in quadrature into a combined and expanded uncertainty, with a Welch–Satterthwaite effective degrees-of-freedom and a contribution ranking. Process Capability & SPC reports Cp/Cpk/Pp/Ppk, the process sigma level, DPMO and yield, plus X̄/R control-chart limits. Gage R&R (MSA) runs the AIAG average-and-range method to separate repeatability from reproducibility and report % Gage R&R and the number of distinct categories. The Requirements Traceability Matrix maps requirements to a verification method and status and reads out coverage and closure, with CSV in/out for your ALM/Jira export.

Verification Passport

Assemble a verification record (requirements → method → result), get a deterministic readiness grade (A–D across coverage, results, standards, review, and identification), and seal it with a tamper-evident SHA-256 hash that anyone can re-derive from the same record.

Standards Library

A searchable library of engineering standards — ASME, ISO, IPC, IEEE, ASTM, AISC, IEC, MIL-STD and more — each with its scope, key requirements, who uses it, when to apply it, and related standards.

Inline calculations in the notebook

In the block-based notebook (both workspaces), insert a calc block: pick any calculation from the same verified registry, enter your inputs, and the result computes live. The block stores only the tool id and your inputs, so it is always re-derivable — and like every number here, it never touches the AI.
