ChatGPT Shopping Gains Visual Search and Side-by-Side Product Comparisons
If you regularly use ChatGPT for product research, this week's shopping update is worth trying. Results are now visually richer, and you can upload a photo of something you already own to find similar products. Comparisons now display price, reviews and features side by side without needing to open separate tabs. OpenAI has also improved the freshness and coverage of underlying product data, which has historically been one of the weaker points of AI-assisted shopping.
The update is rolling out to all users this week. For anyone building shopping-adjacent products on the ChatGPT platform, the richer product result format may open up new integration possibilities worth exploring.
ChatGPT's Outlook Connector Now Covers Shared Mailboxes and Shared Calendars
ChatGPT has extended its Outlook integration to cover shared mailboxes and shared calendars, a practical step that significantly expands its usefulness in team settings. Previously limited to personal inboxes, the connector can now read, organise and reply on behalf of shared team inboxes, and create or cancel events on shared calendars. For organisations running shared support addresses, project management inboxes or team calendars through Microsoft 365, this removes one of the biggest limitations of the existing connector.
If your organisation is already evaluating ChatGPT for workflow automation, this update makes the Outlook integration considerably more relevant for any role that manages a shared inbox rather than just a personal one. It also puts ChatGPT in more direct competition with Microsoft Copilot on Copilot's own home ground.
ChatGPT and Codex experienced a partial service outage on 20 April, affecting users worldwide from approximately 10:05 AM ET. OpenAI confirmed a fix by early afternoon and services were fully stabilised by late afternoon. No root cause has been publicly disclosed. TechRadar, 20 Apr · OpenAI Status
Grok Speech-to-Text and Text-to-Speech APIs Reach General Availability with Competitive Pricing
xAI's standalone Speech-to-Text and Text-to-Speech APIs are now generally available, built on the same production stack that powers Grok Voice, Tesla's in-car AI and Starlink's customer support. The STT API supports 25 languages across 12 audio formats, with word-level timestamps, speaker diarisation and both real-time WebSocket streaming and batch REST modes. Pricing is $0.10 per hour for batch transcription and $0.20 per hour for real-time streaming, which sits competitively against OpenAI's Whisper API. The TTS API generates expressive, natural speech at $4.20 per million characters.
For developers currently evaluating voice infrastructure, xAI's entry is worth a serious benchmark. The underlying models are production-proven at scale across three separate real-world deployments, which removes much of the risk typically associated with a new audio provider. If you are currently locked into a single STT or TTS provider, the pricing and feature set here make a direct comparison worthwhile.
Industry Themes
20-21 April was one of the quieter 24-hour windows in an exceptionally active month. The week of 14-18 April produced Claude Opus 4.7, Claude Design, GPT-Rosalind, Grok 4.3 Beta and Gemini Robotics-ER 1.6 in rapid succession, and that pace eased over the weekend and into Monday. The ChatGPT outage on 20 April may also have delayed planned OpenAI communications; quieter days after service incidents are not unusual.
Voice and audio APIs are becoming a serious competitive battleground. xAI's entry into the STT and TTS market with Grok's production-proven audio stack places direct pressure on OpenAI Whisper and ElevenLabs. The signal is that voice infrastructure is no longer the exclusive domain of specialist providers: every major AI lab appears to be building its own audio layer. If you are currently locked into a single audio provider, April 2026 is a reasonable moment to re-evaluate your options and run a cost comparison.
OpenAI's expansion of ChatGPT's productivity integrations (shared Outlook mailboxes, improved Shopping) reflects a deliberate move into territory Microsoft Copilot has been occupying in enterprise workflows. Extending Outlook access to shared inboxes in particular is a direct functional overlap with what Copilot does inside Microsoft 365. The two products are increasingly direct competitors for the same day-to-day AI assistant budget, and the battleground is shifting from model capability to workflow depth.
