Most digital investigators are exposed to material most people will never see.

That exposure often goes untracked.

Not because it isn’t important, because it’s difficult to see.

And without that visibility, it’s harder to recognise when someone needs space, support, or a change in pace.

This is where the conversation needs to move.

S21 Investigator Wellbeing v3.0 is now available to help teams better understand exposure across investigations - in a way that’s responsible, non-intrusive, and grounded in operational reality.

Wellbeing in digital investigations isn’t separate from the work, it’s part of doing it properly.

We talk a lot about technology in digital forensics, but not enough about the people behind it.

The Forensic Focus International Well-Being Study is closing soon, and it’s one of the most important chances we have to highlight the realities investigators face every day.

If you haven’t taken part yet, now’s the time. It’s anonymous, quick, and genuinely valuable.💙

S21 VisionX v3.0.1 is now available.

This release focuses on keeping investigations moving, especially as systems, media formats and Windows environments continue to evolve.

For investigators working with large image and video datasets, small technical issues can quickly become operational slowdowns. Version 3.0.1 introduces several updates designed to keep review fast, stable and interruption-free.

VisionX is designed to help investigators understand large volumes of visual material faster, prioritising relevant evidence while reducing manual review burden.

Great to see so many people at our session today at the NPCC National Missing People Conference.

A huge thank you to everyone who joined us. It was brilliant to speak with so many investigators, analysts and partners who are keen to see faster workflows, smarter AI and safer review processes in action.

You can try any S21 tool for free and see the full platform for yourself. No demo versions and no limits, just the full software investigators are using every day.

Semantics 21 are live at the NPCC National Missing People Conference.

We’re at the NPCC National Missing People Conference over the next 2 days and the team is showcasing S21 tools in action.

If you’re attending, feel free to stop by and take a look at how investigators are using S21 tools to cut review time, surface key evidence faster and work more safely.

We’ll be here throughout the next 2 days and would love to speak with you!

🚨 Introducing S21 AI Describe 🚨
Sometimes the hardest part of an image or video frame isn’t seeing it – it’s describing it.

S21 AI Describe is a new investigative app designed to help with those moments.

It allows investigators to generate clear, structured descriptions of images and video frames, specifically trained to handle CSAM material, reducing the time and burden of manual description while supporting accurate reporting and safeguarding work.

It’s deliberately simple. No training required. No complex setup. Just open and use.

And of course, being an S21 product, S21 AI Describe is offline, secure, and investigator-led – with investigator wellbeing at the heart of it.

🚨 Introducing S21 Deepfake Detector 🚨
Sometimes an image looks real – but isn’t. No context. No certainty. Just a growing risk that imagery has been AI-generated, and decisions still need to be made quickly.

S21 Deepfake Detector is a new investigative app designed for exactly those moments.

It allows investigators to assess whether images are real or AI-generated, supportting confident professional judgement across safeguarding, sextortion, fraud, and intelligence-led work.

Simply drag and drop imagery to evaluate potentially manipulated media – and move from uncertainty to clarity in seconds.

It’s deliberately simple. No training required. No complex setup. Just open and use.

And of course, being an S21 product, S21 Deepfake Detector is offline, secure, and investigator-led.

🚨 Introducing S21 School Badge Lookup 🚨
Sometimes the only visible lead in an image is a school badge.

No name. No location. Just a partial or low-quality crest on a uniform, and time matters.

S21 School Badge Lookup is a new investigative app designed for exactly those moments.

It allows investigators to identify schools from imagery using a structured collection of school badges across Great Britain, Ireland, Canada, the USA, and Australia.

Search by:
▪️ School name
▪️ Region
▪️ Or partial visual description of the badge

…and move from uncertainty to clarity in seconds.

It’s deliberately simple. No training required. No complex setup. Just open and use.

And of course, being an S21 product, S21 School Badge Lookup is offline, secure and investigator-led.

🚨 Just announced 🚨

We’ve launched three new S21 investigative apps, built to solve real investigative problems quickly and simply.

Investigators are dealing with imagery that’s harder to interpret, easier to manipulate, and more burdensome to review – often with tools that were never designed for that reality. These new apps are designed to close that gap.

Introducing:
▪️ S21 School Badge Lookup
▪️ S21 Deepfake Detector
▪️ S21 AI Describe

Each app focuses on a specific task investigators face every day – the kind that shouldn’t slow work down, but often does.

They’re deliberately simple: no training required, no complex setup – just open and use.

Designed to support professional judgement, not replace it.

🌐 Full details and how to get your hands on them can be found at https://www.semantics21.com

Manually writing up interviews after a long shift?

S21 Transcriber turns video and audio into accurate transcripts at speed:
• Advanced diarisation identifies speakers
• Turns media to searchable text and translates
• Exports built for case files, not consumer apps
• Used every day by law enforcement

Teams tell us the biggest change is simple, they get their time back.

If you want to stop manual transcription this year

• Face Upscale pulls useful clarity out of unusable clips
• Automated reports your officers can actually use
• Redaction that doesn’t waste half your day

Organisations are reporting dramatic time savings from the moment they switch.
