Spectrum vs Todoist

Spectrum, from Photon, launched on Product Hunt today with 105 upvotes and a simple but sharp premise: your users don't want to learn a new AI interface—they want AI to show up in Slack, Teams, email, and every other tool they already use. Spectrum is an agent deployment layer that routes your AI agents to wherever your users are, with no per-integration custom dev work. The core product is an abstraction layer that handles the connector plumbing: authenticate once, and your agent can receive messages and send responses across all connected channels. Built-in conversation management means agents maintain context across channels—a user can start a request in Slack, continue it in Teams, and finish in email without losing thread. The platform also handles rate limiting, authentication, and error handling for each channel. For teams building internal AI tools or customer-facing AI assistants, this solves real integration pain. Building a Slack bot, Teams integration, email handler, and web widget separately takes weeks per channel. Spectrum reduces that to a single agent definition deployed everywhere. The question is pricing and lock-in: if Photon becomes the integration layer, they sit in a strategically critical position.

Todoist is a clean, cross-platform task manager with natural language input, labels, filters, and Karma system. Simple but powerful for personal and team task management.
