Likan by Veldris

Your data, described, checked and signed. Without a line of JSON.

Likan turns spreadsheets, databases and documents into a validated, signed data package. On-device AI finds the structure, the keys and the personal data for you, and everything works offline on your own PC.

Download for Windows See how it works

From the Microsoft Store for Windows 10 and 11. Mac and Linux are coming soon.

The Drop Board: two data files shown as cards, their fields listed, with a dashed link drawn between their matching keys and a bin for fields to leave out.

How it works

From the files you have to a package a platform can trust

  1. Drop

    Drop files on the Drop Board, or point Likan at a database or an API. It reads CSV, Excel, JSON, XML, Parquet, GeoJSON, shapefiles, and tables in PDF and Word documents.

  2. Describe

    Likan proposes what your data describes: the types, the keys, the links between files. Connect, merge, label or leave out by drag and drop, or shape the model in the Studio.

  3. Check

    Six levels of checks, from files that will not read to personal data in the wrong place. Each finding is explained in plain English, with a fix where there is one.

  4. Sign and send

    Governance labels are set, the package is hashed and signed on your PC, then saved to a folder or published to your organisation's Midgard platform.

Features

Built for the people who know the data best

  • The Drop Board

    Sources become cards and suggested links are drawn for you. Every drag has a keyboard way, and works with a pen or a finger.

  • Three modes, one project

    Simple mode for stewards, Studio for modelling, mapping and record matching, Expert for a text view and a full command-line tool. Switch at any time.

  • Bring your standards

    Start from OWL, RDF, SKOS, JSON Schema, SQL DDL, STIX 2.1, NIEM or a CSV data dictionary, or a template pack scored against your data.

  • Mapping you can see

    Map columns to properties with cleaning steps for dates, numbers, units, lookups and redaction, previewed on your own rows.

  • Governed by design

    Classification, residency, owner, licence, retention and handling labels are required before a package is built.

  • Versioned and reviewable

    Every model change is classed as patch, minor or major. Projects are plain YAML, ready for version control, with undo everywhere.

The ontology studio: types drawn as cards on a canvas, with a form for the selected type's properties, keys and checks.
Validate: findings grouped by level, each with a plain-language explanation and a control to fix it.

On-device AI

AI that classifies and identifies your data, and never leaves your PC

Likan's detection engine recognises formats, units, identifiers, keys, links between files and personal data such as names, addresses and postcodes. Its own open-licence language model suggests types, mappings, governance labels and fixes.

  • Runs on your processor, or your graphics card where there is one
  • Sealed in a sandbox with no network access at all
  • Every suggestion shows its evidence and confidence
  • Nothing is applied until you accept it
  • Never restates personal data in what it writes
  • No data goes to a cloud AI service

Security and privacy

Nothing to connect to, nothing sent anywhere

  • Offline by default

    No account, no sign-in, no licence check, no telemetry and no update check. Likan connects to nothing unless you add a connection in Settings.

  • Signed for the long term

    Packages are hashed and signed with ML-DSA, a post-quantum signature standard (FIPS 204), using an identity kept in Windows key custody.

  • Verified on every launch

    The installation checks its own signed manifest each time it starts, and says plainly if any file is not what was installed.

Where your package goes

Made for the Midgard platform

Likan produces Midgard Ingestion Packages (MIP 1.0) for the Midgard platform from Veldris. Building, validating, signing and saving a package needs no connection to anything. Publishing online, team review on a shared server and the Mimir assistant need a Midgard deployment run by your organisation.

Learn about Midgard at veldris.io

Send to Midgard: what will be sent, the governance labels, the assistant's part and who signs the package, with a button to build, sign and save it.

On-device AI suggestions need a processor with AVX2, FMA and F16C and at least 6 GB of memory. On other PCs they are switched off and everything else works. The AI model is kept in your user profile on the system drive (about 2.5 GB). Likan uses Microsoft Edge WebView2, which is part of Windows 11 and is kept up to date on Windows 10 by Windows Update.

Accessibility

Mouse, keyboard, touch or pen

Likan is built to WCAG 2.2 AA, in light, dark and high-contrast themes, in plain British English. Every drag works with a pen on a Surface or other pen-enabled PC and has a keyboard way; handwriting goes into any text field.

Accessibility statement

The Drop Board in the dark theme, with a confirmation asking whether to leave a source out.

Questions

Frequently asked

Does Likan need an internet connection?

No. Once installed, everything works offline: detecting, modelling, mapping, checking, signing and saving. The Microsoft Store needs a connection to install it.

Does my data leave my computer?

No. Likan, including its AI, works on your PC. Data goes elsewhere only if you add a connection, such as your organisation's Midgard platform, and choose to publish.

Do I need Midgard to use Likan?

To build, check, sign and save packages, no. The packages are made for Midgard, and publishing them online needs your organisation's Midgard deployment.

Is there a Mac or Linux version?

Likan is available for Windows now, from the Microsoft Store. The Mac App Store, Flathub and Linux packages are coming soon; news is published at veldris.io.

Does it run on HoloLens or Arm PCs?

Not as an app. Likan needs a 64-bit Intel or AMD processor. HoloLens will be able to use Likan's web application in Microsoft Edge once it is released.

Can my IT team deploy it?

Yes. Organisations can deploy the Microsoft Store app with Intune. For managed estates and offline networks, Veldris also provides a signed MSI; contact Veldris at hello@veldris.io.
