// Changelog

What shipped, when.

Dated by the day a change reached production. Anything planned is labelled as planned elsewhere on the site; nothing planned is listed here.

  1. design

    The redesign, the Engine Index, and a public audit

    • New marketing site: feature, solution, integration, research, glossary, changelog and company pages; a scroll-driven explanation of how an audit works; a hero rendered by our own light-scattering shader.
    • Engine Index — a live, aggregate benchmark of engine behaviour computed hourly from stored audits, with sample sizes on every row.
    • Showcase audit: the homepage can render the operator's own latest audit, verbatim, in place of a mockup.
    • Dashboard: persona comparison chart, engine leaderboard, command palette (⌘K), report-style audit detail, dithered empty states.
  2. feature

    Lifecycle email and the shared sender

    • Welcome, first-audit-ready and no-brand-yet emails, each sent once and each carrying a one-click unsubscribe.
    • All product mail — alerts, digests, invites — now goes through one sender with retries and failure reporting.
    • The public API section is labelled as in development; the sample endpoint is marked as a proposed interface.
  3. improvement

    Timeouts, coverage and traffic analytics

    • Audits run under a wall-clock budget; a run that hits it is scored on what completed and marked as partial coverage rather than failing outright.
    • Stale runs are reaped automatically; the weekly monitor shares its budget fairly across workspaces.
    • Privacy-preserving page-view analytics (no cookies, no cross-site identifiers).
  4. security

    Free-tier guard and security hardening

    • Per-user and per-IP rate limits on audit runs, enforced in Postgres.
    • Usage metering functions now verify workspace membership before writing; invitation acceptance is no longer callable anonymously.
    • Structured error reporting with optional webhook delivery.
    • Scheduled weekly monitoring is enforced as a paid-plan entitlement in the cron itself.
  5. improvement

    Agency plan

    • The Scale plan is renamed Agency and repositioned around multi-brand workspaces, white-label reports and exportable evidence.
  6. feature

    Bring your own keys

    • Workspaces can store their own engine API keys, encrypted at rest with AES-256-GCM. Audits run on your account; keys never reach the browser.
    • Multi-run columns documented and made idempotent across migrations.
  7. feature

    Multi-run confidence and mention basis

    • Paid plans ask each prompt several times; agreement between runs is stored as variance and shown as stable / some variance / high variance.
    • Every mention is classed as retrieval (backed by a live citation) or training (no source) — and labelled that way in the evidence line.
  8. feature

    Synthic launches

    • AI Search Audits across ChatGPT, Claude, Gemini, Perplexity and Grok via official APIs, with every answer stored verbatim and a published Visibility Score formula.
    • Hallucination Defense: claim-by-claim verdicts against your live site, with severity and corrections.
    • Schema & llms.txt generator, AI Crawler Access for 16 agents, Share of Voice, five buyer personas.
    • Prompt Explorer and Discovery, Citations & Sources, Sentiment, AEO Site Audit, Content Optimizer, Agent Analytics from server logs.
    • Google Search Console and GA4 integrations, Slack and email alerts, scheduled reports with shareable links and CSV export.
    • Workspaces with roles and invitations, Stripe billing, audit log, white-label reports; keyword, rank and backlink data via a provider.
