Other AI tools

Gyazo is a screenshot and screen recording tool built around an asynchronous visual communication experience of "instant capture, quick search, one-click sharing." It supports capturing screenshots with customizable hotkeys without interrupting your current workflow, completing screenshot, upload, and shareable link generation in one step; it can also record videos and key moments from meetings. Captured content can be organized into themed collections, each with its own separate sharing link, and supports collaborative team editing. Gyazo can automatically recognize text in images, allowing searches by app name, URL, OCR text, or description, and can also add tags and notes to screenshots for easier retrieval later. For sharing, images or videos automatically expand once a link is pasted, support adding arrows and text annotations, cropping content, and allow adding voice or webcam narration during capture. The official page mentions the paid version Gyazo Pro, which can record HD videos up to 10 minutes long, create an unlimited number of collections, browse historical captures at any time, and use the latest AI to extract text from images and videos for search and sharing.
