Tesseract

Tesseract is a free desktop app (Mac, Windows, Linux) with an AI agent that hands back finished work instead of a paragraph of advice. Say what you need and it plans, works on your computer and returns the result: a website with a live preview, a slide deck that opens as real PowerPoint, a short video with voice and music, a logo and brand kit, or a sourced research spreadsheet. It runs Claude Code, Codex, Gemini CLI and 11 more agents, so the Claude or ChatGPT plan you already pay for is all it needs. Step away and it keeps going, then shows you every decision it made.
