Changelog

Site navigator, sign in with HANC AI, and rewritten legal documents

Site navigator

• The Studio reads your website and assembles an index of its pages, fields and buttons — the navigator is built from that, not from a written description.
• The agent walks a visitor through the site by voice: it opens the right page, highlights an element, presses a button. The call stays up and survives the page change.
• The widget loads when the visitor asks for it rather than on every page.
• The navigator does not answer about panels the visitor cannot see, and it can start inside an application that is already open.
• Every command the page receives is logged, so diagnosing a bad call is no longer guesswork.

Sign-in and account

• "Sign in with HANC AI" on the login page: the profile is read from userinfo, and the account can be linked and unlinked in settings.
• Profile settings moved into the account menu; the system prompt and the configuration panel stayed behind admin.
• Registration is protected by a Cloudflare Turnstile captcha, and failed attempts count toward the IP lock.

Payment

• Charges and purchases run in euro — exactly what the interface always showed.
• Checkout sessions are stamped with the product, and only our own are credited.
• The Stripe customer is re-created when the stored identifier no longer resolves.

Build quality

• The builder moved to gpt-5.4-mini, while every built agent and sub-agent is pinned to gpt-4.1.
• The greeting is folded into the first question, so a call opens with one utterance instead of two.
• A workflow that greets, pauses and only then asks no longer passes verification.
• The reference library is seeded with the Martin and Lena workflows, and the match threshold is calibrated to the embeddings model in use.
• Each locale example names its own language instead of Russian.
• Added coverage and mutation simulations, judge calibration, self-CI, a closed-loop auto-repair pass and real-call ingestion.

Interface and documents

• One brand header across the landing, the sign-in page and the studio; filled buttons are flat violet instead of a gradient.
• The sign-in pane is built around the reactor, and the German version is fully translated.
• The hero clip is debanded at the source and three.js loads as its own chunk.
• The studio refuses to render inside a third-party frame.
• The terms of use and the privacy policy were written from scratch and are available in Russian, English and German; the blog and the changelog switch language too.

A new studio: graph editor, automatic call test and a new interface

Graph editor

• Nodes, branches and actions are added, edited and removed in place — one atomic operation, without rebuilding the agent.
• Node text edited by hand in HANC is pulled in before a patch and is no longer overwritten.
• Deleting an already deleted node or edge a second time no longer breaks the edit batch.
• Restoring a version applies straight to the current workflow, so the result is visible at once.

Scenario quality

• Branches on a collected variable go through a silent classifier, and conditions that are always shadowed are dropped.
• The escalation number is taken from the brief and validated against E.164.
• Sub-agents get their own tools, actions and knowledge base instead of inheriting the parent’s settings.

Studio

• A new brand style: the violet theme, light and dark, on every page.
• A new public landing page with a video cover, a live graph-building demo and RU / EN / DE.
• The conversation is stored in the database and restored when the page reloads.
• Blog, changelog, terms and privacy are editable in the admin panel, and the footer carries the site map.

Dependable workflow builds

• An honest build status: "Done" appears only when this turn actually created or changed something.
• A fallback skeleton is no longer passed off as a finished scenario: if it cannot be built to the requirements, the answer is "build failed", not a stand-in draft.
• Strict graph verification: unreachable nodes, dead ends and nodes with no path to the end of the call block the build.
• Smart loop termination: every strongly connected component is analysed, so unconditional loops are caught even when hidden.
• Conditional branches must have a fallback path, and the classifier helper must stay silent.
• Edits by meaning: "the first greeting", "the Tesla branch" — no internal ids required.
• A build certificate: a report on connectivity, endings, loops and helpers.
• Blog and documentation right inside the studio.
