Tools · made by us, often free

Tools we build and give away.

We build them for ourselves first. When they're useful to others too, we make them free: no account, no subscription.

01Desktop app · Mac, Windows, LinuxFreev0.4.0

PDF Toolkit

Sign, fill and fix PDFs. On your computer, not in the cloud.

A desktop app to sign, fill, merge, split and tidy up PDFs — with offline OCR in Italian and English. No account, no cloud: your files never leave your computer.

Installed apps update themselves

    Text, dates, drawn or uploaded signatures, stamps, images, highlighter and true redaction.

  • Forms

    Fill in existing fields or create new ones: text and checkboxes.

  • Pages

    Reorder, rotate, merge, split, extract, crop and export pages as PNG.

  • Scans and OCR

    Straighten, clean the background and recognise text offline, in Italian and English.

  • Saving

    Passwords and permissions, compression, hidden-data removal, PDF/A archiving.

  • Documents

    Editor with quote, invoice, contract and letter templates, exportable to PDF.

  • AI assistants

    Optional local MCP server, off by default: Claude reads, fills and signs with your confirmation.

  • And more

    PDF comparison, signed .p7m files, bookmarks, attachments, printing and automatic updates.

On macOS the app isn't signed by Apple yet: the first time, right-click the app, choose Open, then Open again. From then on it updates itself.

02Secrets manager · Developer tools

Shush

A secrets manager that thinks like a developer.

Encrypted, auditable secrets with first-class environments, version history and a runtime API — so teams stop hunting for .env files in Slack.

Try Shushshushsecrets.dev

  • Envelope encryption

    AES-256-GCM: a master key wraps a per-organisation key.

  • Mandatory 2FA

    TOTP on every account, no exceptions.

  • Environments with diffs

    Dev, staging and prod inherit and override, with visual diffs.

  • Never on disk

    The CLI and SDKs inject secrets into the process at runtime.

03EU AI Act compliance · SMEs

Logical AI

EU AI Act compliance the average SME can actually follow.

A platform that maps a company's AI systems, classifies their risk under Regulation (EU) 2024/1689 and trains the team — assessment plus an LMS, in plain language.

Go to Logical AIai.logicaltech.it

  • Guided wizard

    The company opens it from a one-time link, no account to create.

  • 4 risk tiers

    Every AI system classified according to the regulation.

  • Deterministic report

    No generative AI in the assessment: auditable and repeatable.

  • Article 4 training

    Lessons, quizzes you retake until you pass, certificates.

Shush and Logical AI were born from a real problem. If you have one too, let's talk: we'll tell you what we'd build and what it costs.
