Flowstep: Your AI Design Assistant
Flowstep
Generates production-ready UI from text prompts with chat-driven iteration, Figma export, code export, and IDE integration via MCP.
Key features
- Production-ready UI Generation: Converts plain-text prompts into structured, production-quality user interfaces ready for further refinement or export.
- Chat-driven Iteration: Provides a conversational interface to iteratively tweak layouts, components, and visual details without leaving the tool.
- Figma Export: Copies or syncs generated UI directly to Figma as editable layers and components for designer workflows.
- Code Export: Exports implementation-ready frontend code from designs to accelerate developer handoff and reduce manual translation.
- IDE Integration via MCP: Connects to developers' IDEs through MCP to pull designs and code directly into development environments, streamlining integration.
- Generate production-ready UI from natural language text prompts
- Chat-based iterative refinement of generated UI
- Copy or sync designs to Figma
- Export frontend code from generated designs
- Connect IDEs via MCP for direct developer integration
- Support for rapid prototyping and design-to-development handoff
Best for
- Rapid MVP UI Creation: Produce initial, production-ready interfaces from product requirements to accelerate minimum viable product development.
- Designer–Developer Handoff: Export polished designs to Figma and generate code to minimize manual translation and speed up implementation.
- Iterative Design Exploration: Use the chat interface to quickly explore multiple layout and style variations with instant updates.
- Frontend Acceleration for Teams: Generate reusable components and export code to reduce repetitive UI implementation work across projects.
- Embedding into Dev Workflows: Connect via MCP to bring generated UI and code directly into a developer's IDE for faster integration and testing.
- Rapidly create UI mockups and prototypes from product requirements or user stories
- Accelerate design-to-code handoffs by exporting production-ready frontend code
- Enable designers to push iterations quickly into Figma for collaboration
- Allow developers to connect their IDE and import UI artifacts into the codebase via MCP
- Prototype new product flows and validate user interfaces with stakeholders

Voicebox is a free, open-source, local-first AI voice studio for cloning voices, generating speech in 23 languages, and dictating anywhere.
Key features
- Voice Cloning: Clone a voice from a few seconds of audio and reuse it across generation and dictation.
- Multi-Engine TTS: Generate speech in 23 languages across 7 engines including Qwen3-TTS, Chatterbox, HumeAI TADA, and Kokoro.
- Global Dictation: Hold a customizable key chord anywhere to record, transcribe, and refine straight into any text field via an on-screen pill.
- Captures Tab: Every dictation, recording, and upload is preserved with its original audio paired to a transcript.
- MCP Agent Voice: Give any MCP-aware agent such as Claude Code or Cursor a voice of your choosing that speaks back through a pill.
- Local Processing: Runs Whisper transcription and a bundled local LLM on your machine via MLX or PyTorch, with a REST API for integration.
Best for
- Hands-Free Writing: Dictating into any app with a global hotkey instead of typing.
- Voiceover Production: Cloning and generating narration in multiple languages locally.
- Agent Voice Output: Giving coding agents a spoken voice for feedback.
