What Kastel shipped, week by week.

kastel.ai publishes its core pages: how Kastel works, its security and compliance posture, the Enterprise offer, and an index by industry (healthcare, services).

The terms of service and the DPA (data processing agreement) are live, in French and English.

A document pulled in from a connected source becomes searchable automatically, with no admin needing to trigger a manual reindex.

A piece of information can now carry an explicit expiry date. Past that date, Kastel stops serving it as current, unless someone explicitly asks to see the history.

Kastel now warns before a piece of information reaches its expiry date, with an optional automatic notification, off by default.

Every self-host install now shows an honest freshness indicator for its last backup, with a setup-time reminder about keeping regular off-machine backups.

kastel.ai gets real navigation (Product, Solutions, Pricing), a direct sign-in link to the console, and a dropdown menu by industry.

An admin can now remove a teammate from their organization directly from Settings then People, with immediate revocation of their access.

The pricing page gets a full feature-by-plan comparison table, and the homepage shows a short pricing reminder.

In managed mode, every connected AI now gets its own access tied to the person who authorized it, time-limited, renewable, and revocable at any time from the console, instead of a shared organization token.

The public pricing page is live at kastel.ai, and the five-plan lineup (free Kastel Core, Solo, Team, SMB, Enterprise) is wired end to end in the console, with plan selection and a display of the plan actually subscribed to.

Source-validation requests, approvals, and pending questions now live in a single Decisions screen, automatically routed to the right person by department.

Every answer can now get feedback (helpful or not), with an optional comment, visible to admins.

Your choice of AI providers grows by four, plus an advanced mode to connect any compatible provider. Each one shows its jurisdiction and its data training policy, sourced and dated.

An employee can request validation of an unverified source in one click; the request is automatically routed to the relevant department's owner.

An answer can now show, on request, the sources actually used and a confidence indicator.

Excel tables, Word headings, and PowerPoint slide order are now carried over faithfully on extraction, where they used to get lost.

Kastel now reads scanned images via text recognition, Office files with macros, and open formats (.odt, .ods, .odp).

A company that started on free self-host can now switch to managed without starting over.

The console now shows real AI spend on your own keys, broken down by usage type, with a configurable threshold alert.

A dedicated space lets an integration partner create and track several client Kastels, and offer ready-made configuration templates.

Payfit, Factorial, Deel, Sage, QuickBooks, Xero, PandaDoc, DocuSign, Folk, Zoho CRM, Calendly, Gong and more join the catalogue. Sensitive-data connectors structurally exclude IBANs, signed-document contents, and personal contacts.

A single command (npx @kastel/connect) automatically connects Claude Code, Claude Desktop, Cursor, Codex CLI, Gemini CLI, and Copilot CLI to your Kastel. A kit of ready-made skills (meeting recap, decisions, action items, blockers) installs alongside it.

Pending questions are no longer capped, get routed to the right person, and are centralized in a dedicated screen with per-person notification preferences.

Connected AIs, and now humans from the console, can browse the structure of your Kastel (pages, links between pages, topic indexes), not just search by keyword.

A connected AI can ask Kastel who, in the company, has decision authority or demonstrated expertise on a given topic.

An organization can define a reusable context recipe for a recurring task, for example answering a support ticket, that connected AIs can call directly instead of rediscovering it every time.

A public guide gives copy-ready instructions to connect Claude Code, claude.ai, Claude Desktop, Cursor, ChatGPT, or any generic MCP client to your Kastel.

After Google Drive, Gmail and Slack now connect in one click from the console, without touching the command line.

The console is now organized around a unified "My Kastel" view, with a health indicator on the home screen and an automatic suggestion of new departments when unclassified content is detected.

Gmail, Google Drive, Slack, Notion, HubSpot, Microsoft Teams, Confluence, Jira, GitHub, Salesforce and more join the catalogue, each with its own rule for who has the right to see what. Part of the free core, never gated behind a paid plan.

A customer runs their own verification question sets, never exposed, to check what an AI model actually answers from their content.

The engine contains no call-home mechanism to Kastel's servers, no expiry, no remote kill switch. Permanently deleting a managed instance produces a cryptographically signed attestation.
