## About Magnus

Magnus is a platform for founders, startups and small and medium-sized businesses that describes itself as an SI Agent Store. Users pick ready-made agents, give each one a mission and goals, and let the agent work through the routine tasks that take up their time. The site presents its assistant as a chief of staff style tool with a 3D talking-head interface, and says it can pursue goals, draft documents, remember context and connect to your tools.

The site shows example goals such as bouncing back from a quarter that went off track, protecting the team's focus, winning back a lost client, keeping deadlines, and building a 30-day habit. Each goal appears with a status such as active or complete. Magnus says it runs on a choice of underlying AI models, with Claude, OpenAI and OpenRouter named on the page, and it notes that voices are powered by a third-party provider.

The product is aimed at founders and leaders who want to hand repetitive operational work to agents while keeping control of their objectives. A seven-day free trial is offered, with cancellation available at any time and no hidden costs stated.

## About Petal

Petal is a personal PDF editor that works in the browser. Instead of using menus and toolbars, you describe the change you want in plain words and Petal applies it to your document.

According to the site, it can edit, merge, split and convert PDFs. It describes itself as private, safe and only yours, and it can be started for free.

Petal is aimed at individuals who need to change PDF files without learning a full PDF editing tool. Paid plans exist alongside the free start, though the page text does not detail what each plan includes.
