Best AI Agent Tools

DPI Converter is a free online tool that changes the resolution of any image in seconds, letting you set values such as 72 DPI for web or 300 DPI for professional printing. Unlike tools that only relabel a file, it modifies the actual EXIF and resolution metadata, so the change is real and usable by print services.

The tool supports JPG, PNG, WebP, and GIF, with drag-and-drop upload and the option to enter any custom DPI value. There is no signup, no watermark, and no usage limit, and uploaded files are processed in isolated server memory and deleted immediately after download. For designers, sellers, and anyone preparing images for print or web, it offers a quick, private way to get the right resolution.

Rossy AI is an AI-powered voice agent that answers business phone calls automatically, using conversational, human-like speech to handle inquiries around the clock. When a call comes in, the agent responds within seconds, works to understand the caller's intent, answers common questions using a knowledge base trained on the business's own policies and FAQs, and can book appointments directly by checking calendar availability and accounting for time zones. If a request is too complex or falls outside what it's trained to handle, Rossy AI transfers the call to a human staff member so it doesn't go unanswered. After each call, it sends a text or email summary so teams stay informed without needing to listen to every recording.

Setup does not require code: businesses sign up, share details such as business hours and calendar access, customize greetings and call-routing rules, and then either get a new phone number or forward an existing one for Rossy AI to start answering. The platform connects with more than 30 third-party tools, including Google Calendar, HubSpot, Salesforce, Zapier, Slack, Zendesk, and Twilio, so call data can sync with existing CRM and scheduling systems. It's marketed toward businesses with high call volume, including home services like HVAC, plumbing, and roofing, automotive, eCommerce, professional services such as law and accounting, food and beverage, SaaS companies, digital agencies, and education. It suits businesses that miss calls during busy periods or after hours and want scheduling and FAQ handling automated without adding phone staff.
