Heisen for VS Code
Verifiable AI, inside your editor.
Heisen for VS Code brings the substrate into your editor — sidebar chat, right-click ask / fix / explain, one-click tests — for research and development alike. Exact work resolves on deterministic engines, every answer is checked, and the per-message cost is always in view.
The Heisen posture, in your editor.
Not a generic completion plugin pointed at someone else's model. Heisen for VS Code runs the deterministic substrate first — so the work that's exactly computable resolves without a model, at zero cost, traceable to a function and reproducible run-to-run. A specialist handles judgment ; a frontier model is the rare last resort ; and every answer passes a coherence check before it lands in your editor.
Ask, fix, explain, test — without leaving the file.
The whole loop, surfaced where you already write code and notebooks — with the cost of every step in view.
Sidebar chat + inline
Ask a question, get an explanation, accept an edit — in a side panel or right in the file, with your code as the context. No copy-paste into a separate window.
Right-click ask / fix / explain
Select code, right-click — ask about it, fix it, or explain it in place. The editor's own context menu, with the substrate behind it.
Verifiable answers
Exact work resolves on deterministic engines, traceable to a function — not a probabilistic guess you have to re-check before you trust it.
One-click test generation
Generate tests for a function or a notebook cell — edge and degenerate cases covered, so a result holds up to replication.
Per-message cost in view
See the cost of every step as you go. Most resolve at $0 on the substrate ; you only pay for the rare frontier call.
Talks to any deployment
Point the extension at a cloud, on-prem, or fully air-gapped substrate — the editor experience doesn't change, your security posture is your call.
One extension, any substrate.
The extension is the surface ; the substrate it talks to is your call. Pick the posture your security review demands.
Cloud
Connects to Heisen on Canadian-resident infrastructure. Fastest to start, fully managed, nothing to provision.
On your hardware
Point it at a substrate inside your own environment — a compact on-prem appliance, no datacenter required. Nothing leaves your perimeter.
Air-gapped
Talks to a fully disconnected substrate. No network, no telemetry, no phone-home. For codebases that legally cannot touch the internet.
What you'd run it for.
Research and dev work alike, resolved in the editor with output you can trust, trace, and reproduce.
Work in data notebooks
Jupyter and data work in the editor — exact calculations, unit-checked, traceable to a function and reproducible run-to-run.
Explore & understand code
Ask questions across the repo without leaving the file ; answers are cross-checked against a coherence signal before they reach you.
Reproduce a computation
Re-run an analysis or experiment from the editor — deterministic, so it reproduces exactly, on your machine or a reviewer's.
Generate & review code
Scaffold, write, and review code with the deterministic substrate underneath and the source behind every suggestion.
Generate & maintain tests
One click turns a function or cell into a test suite — edge cases covered, kept in sync as the code changes.
Debug & fix in place
Trace a failure to its root and fix it where it lives, with exact computation where a model would only speculate.
Built for researchers and developers who verify.
Research, data-science, and engineering teams who live in the editor — and need an answer they can reproduce and defend, not babysit.
Powered by Heisen.
Every action runs through the same deterministic compute substrate — classify, resolve locally, escalate rarely, verify. The extension is the surface ; Heisen is the engine.
