Developer tools / Xynapse
Xynapse IDEBuild with AI.
Stay in control.
Your editor, terminal, Git and AI assistant in one workspace. From a question about code to an inspectable plan for changing it.

01 / Workflow
Context. Plan. Changes.
Assistance at every development step, with explicit access modes.
Project context
Attach files, selected code, diffs, diagnostics and terminal output. Work with the context you choose.
A mode for the task
Chat explains code, Plan inspects without edits, Agent implements changes. Full is for explicitly authorized system tasks.
Several perspectives
BVC collects independent proposals, adds critique when needed and saves the final plan.
Provider choice
Configure chat, editing and autocomplete models. YandexGPT and GigaChat adapters are available; your provider bills model usage.
A demo, step by step
One small defect. The complete engineering loop.
- Open a project
Choose a task and attach the relevant files.
- Review a plan
Run BVC, inspect proposals and agree on the scope.
- Make changes
Give the plan to the agent and inspect the diff.
- Verify the result
Run tests and review the changes before accepting them.
02 / Research
Results you can inspect.
Author manuscripts with methods and limitations. No claim of journal acceptance or publication.
A budget for multi-role analysis
In the research protocol, 32 tasks used the short 6-call route and 28 used the extended 10-call route: 472 calls instead of 600.
Quality is a separate measure
Resolved tasks in the same sample: direct 4/60, single plan 7/60, BVC 5/60, full council 6/60. Neither superiority nor non-inferiority of BVC quality was established. These are research-protocol results, not a promise about the current release.
Experiment methodology ↗Adaptive BVC budget
A rule for choosing a short or full route. Calls, tokens and estimated cost.
Read PDFReproducible BVC evaluation
Protocol, paired method comparisons and official patch evaluation.
Read PDFBVC before the first edit
Upfront planning, conversational prompts and repeatability.
Read PDFControlled network egress
A Xynapse IDE cold-start study: 19 source checks and three independent 60-second runs.
Read PDFNo TCP/UDP events attributed to the tested Xynapse.exe were observed in the cold-start study. This applies to one build and scenario, not complete network isolation. Model calls, DNS, Git and differently named processes are outside the result.
03 / Transparent arithmetic
Explore the call budget.
Scale the observed route mix to a different batch size. A new set of tasks can produce a different result.
Observed research mix: 28/60 tasks with critique. Formula: N × (6 + 4p); full council: N × 10. This model does not estimate patch quality, time or current API prices.
Estimated cost in the same sample: RUB 1,838.46 vs RUB 2,402.61, using a frozen research tariff. These are not provider invoices or current prices.

Your project. Your next step.
Use the complete editor or add the assistant to a compatible VS Code installation. Configure your provider before the first request.
IDE 1.108.0 bundles Assistant 1.0.0. The standalone VSIX updates Assistant to 1.0.1 and BVC to 0.1.1. Windows executables are currently unsigned.
