Build working apps, websites, and AI agents by describing them
Describe an idea and get a working app with database, authentication, payments, and hosting already wired up — no server or infrastructure setup.
Generates complete websites with layout, copy, and design, plus built-in SEO tools and custom domain support, ready to publish in one click.
Create 24/7 AI agents that connect to your tools, take real actions, manage data, and automate recurring workflows autonomously.
Connects to Google Calendar, Gmail, Slack, Notion, HubSpot, Salesforce, and more, with API access for anything else you use.
AI noise cancellation, call recording and meeting minutes for cleaner virtual meetings
Removes background noise coming from your microphone and from the other participants on the call, plus acoustic echo and room reverberation.
Isolates your voice and heavily attenuates other speakers in the same room, which is handy in cafés, shared offices and open-plan spaces.
Records screen and bi-directional audio, generates transcripts and automatic titles, then distils smart meeting minutes, keywords and sentiment.
Cleans up existing mp3, wav and flac recordings — useful for podcasts, interviews and voice-overs that were captured in noisy environments.
Powerful full-stack app generation from natural language, but offers more polished UI components and smoother deployment flows.
