The 7 Best AI Features For Messaging Apps

Many common AI capabilities for messaging and collaboration apps can run locally on phones, tablets, and desktops rather than through cloud-hosted large language models, offering stronger privacy, lower latency, and no per-token costs at the expense of some capability and potential device-performance constraints. The described examples, built with Stream Chat components and Stream Agent Skills, cover seven uses: image background removal with segmentation models such as SAM 3, text refinement through writing tools and Foundation Models, speech-to-text using Apple’s Speech Analyzer and SpeechTranscriber, general-purpose assistants, image-understanding vision agents such as MiniCPM 4.5, AI-generated reply drafts, and media generation including text-to-image and short video creation. The approach can support broader applications such as captioning and summaries in video conferencing, content moderation in live communities, and recommendations in marketplaces, while developers choose suitable local or cloud models and platform SDKs for Android, Flutter, iOS, React, or React Native. Although many models can operate successfully on Apple devices, demanding vision and media-processing workloads may cause overheating, slow responses, or reduced device responsiveness, making testing and model selection important.
