LayerBack
LayerBack solves a specific annoyance: someone sends a diagram as a flat image, and you need to actually edit it. Converting to real shapes and connectors in Visio, PowerPoint, and draw.io formats, plus API and MCP access for automation, makes it more than a one-off web toy, though the free tier's 10 credits won't go far.
Pros
- Outputs to real editable formats (Visio, PowerPoint, draw.io), not just a re-embedded image
- Provides both a REST API and an MCP server for agent-driven automation
- Failed conversions are automatically refunded
- Annual billing cuts the monthly price roughly in half
Cons
- Free tier is limited to 10 one-time credits, good for only a couple of conversions
- Company name and location are not disclosed
- Credit-based pricing makes cost less predictable than a flat per-seat plan
