Meet the developers of the Nextcloud Polls app! In this special edition blog, we've interviewed the creators behind it: Vinzenz and René.Per saperne di più
Over the last year, AI has become a popular topic. Some is hype, some is substance. Some is good, some is bad. We want to give you the good, not the bad, and ignore the hype!
In Nextcloud Hub 4 and 5, we’ve focused on providing you the best tools that AI has to offer. Benefits like improving your work productivity and jump starting creativity, AI features can enhance your Nextcloud experience.
To fit everyone’s needs, we offer several types of integrations for AI, from completely self-hosted options to integrations with external services.
If you’re interested in setting up Nextcloud’s AI features on your instance, then keep reading for a breakdown of how to enable and use each one! 💙
First, let’s understand the difference between self-hosted AI features versus integrations from external services.
All self-hosted AI features are built-in and only run on YOUR server, meaning no data leaves your premises and you’re in full control. Our self-hosted options can be installed from the Nextcloud App Store. Some are built-in and some require some command line commands to be run to download Ai models.
We also offer AI features using remote AI services from companies like DeepL and OpenAI (ChatGPT and DALL·E). These features can be enabled on your server but data from the app is sent to the third party. Note that nothing is ever sent to external services by default unless you explicitly enable those features or install the related apps. However, if you like these services, then they are available to you!
For some use cases, tools like ChatGPT might be a reasonable solution, while for other data, it is paramount to have a local, on-prem, open solution. To differentiate these, we developed an Ethical AI Rating.
For every AI feature that Nextcloud supports, a rating is established. This shows you the risks you take with your data is when using a feature and it gives you a quick insight into the ethical implications of your choice.
Is the software open source? (Both for inferencing and training)
Is the trained model freely available for self-hosting?
Is the training data available and free to use?
All conditions are met

Now, let’s learn about Nextcloud’s AI features, their rating and how to enable and use them!
LocalAI is an open source API that allows you to set up and use many AI features to run locally on your server. However instead of connecting to the OpenAI API for these, you can also connect to a self-hosted LocalAI instance with the Nextcloud LocalAI integration app.
The AI features LocalAI supports:
Your cloud is full of photos, but sometimes the image you need isn’t there. Maybe it is somewhere on the web, or maybe you can only visualize it in your head? With AI image generation, you can type in keywords to create the image you’re imagining. Your instant AI generated image can be inserted into a Talk chat, Notes and much more.
To use OpenAI’s DALL·E 2 images or the on-premises StableDiffusion based generator, just install the OpenAI integration app. You can find instructions to get the model in the settings!
This feature is very versatile on Nextcloud, being able to insert an AI generated image in a document, Talk chat and more. To use this feature in your Nextcloud, open up the Smart Picker by typing a slash (/) in your document, Talk chat and more!
How do you craft intelligent, professional text? With the text generating tool in Nextcloud Talk, Office and Mail of course!
For the on-premises option, you also install the OpenAI app to communicate with a self-hosted instance of LocalAI which can run language models to generate text. See instructions.
To use OpenAI’s ChatGPT, install the OpenAI integration app.
Sometimes, it’s easier to say something out loud. With Nextcloud’s speech-to-text dictation feature, you can formulate text through your voice. Use your spoken words to send a message in a Nextcloud Talk chat, in an email and through many more applications.
In the speech-to-text transcription feature, your call recordings can be automatically transcribed. This smart feature is great for recording what was said during important meetings for your record keeping.
If the OpenAI integration is installed and configured (using either OpenAI or LocalAI), Talk will be able to automatically produce speech-to-text transcriptions of call recordings. You will receive a transcription file just like the video recording file right after the recorded call ends.
Now let’s talk about our smart feature in Mail. Nextcloud Mail uses Machine Learning (ML) to classify the importance of incoming emails based on your historical data and pattern recognition. This provides you a priority inbox, where your most important messages are at the top. Due to the ML technology, your data never leaves the server.
Luckily for you, this feature is already integrated by default. However, if you want to disable it at any time, you can do so in the bottom left settings of the Mail app.
In your Nextcloud Photos, you can quickly find people, places or objects when using the Recognize app. Recognize goes through your media collection and adds fitting tags which automatically categorize your photos, and even music!
The way Recognize works is through training an artificial neural network that recognizes patterns which yields the results we see. You can learn more about how the app works and facial recognition technology in the blog.
To get face recognition in your Nextcloud, install the Recognize app in the Nextcloud App Store.
“This app is incredible! It works really well. Very easy to set up. It takes a long time for the first recognition, but man, is it worth it! I expected face recognition working well, but I did not expect the tags feature working very well also! It created tags I did not think is possible. Super useful!”György Kiss, Recognize apps rating
Before joining a video call, you have the opportunity to change your background to an image of your choice or add a blur effect. It so happens that this blur “effect” is actually a complex computing contouring that uses Machine Learning (ML). Nextcloud uses the Jitsu library and a model called MediaPipe (both open source) to create this effect.
This feature is ready to be used once you’ve installed Hub 5.
In today’s connected world, you’re bound to be put in a situation where you need to translate a message, word or piece of text in another language. Now you can translate anything with Nextcloud!
Nextcloud provides a translation service app that runs locally on your server. Using open source Opus models by University of Helsinki in Finland, you can rest assured no data can leak.
Use local translation in Nextcloud Talk to translate a message in a chat or in a Text document.
Witness how your writing can be instantly translated in Nextcloud Text.
Enable local translation by installing the Translate app! Languages supported are: English, German, French, Spanish and Chinese so far.
The LibreTranslate integration provides translations using your own server/api key. This translation tool uses open source OpenNMT models.
You also have the option to use the external service integration DeepL. DeepL is a popular translator based in Germany that provides translations in 29 different languages.
DeepL receives a red rating because they use proprietary models and the app connects to their website. Since DeepL is a separate service, data put into this model on your server will be sent to them. Take care to read about DeepL’s privacy protocols and what they do with your data.
Suspicious login detection detects and warns you about suspicious IPs logging into your Nextcloud.
This feature works through learning your behavior of logins – when and where – so if a suspicious login occurs, you’ll be notified in time to change your password or upgrade your security controls.
Suspicious login detection was once an app, but now it is integrated right into your instance. Just go to your admin settings and click on security. As always, the feature can be enabled or disabled per your preference.
