What's Next for PromptMix: Live Preview & Private Templates

By PromptMix Team · Jul 3, 2025

A transparent look at the features currently in design and why they matter.

PromptMix launched with two pillars, now all free:

Users love the speed—but ask for real-time feedback and cloud templates. Good news: both are in active design.

1. Live Preview (in development)

Problem: Switching to ChatGPT to test each prompt breaks flow.

Solution outline

  1. User pastes their own OpenRouter or OpenAI key in Settings.
  2. Hit Preview → PromptMix sends the combined prompt to the model.
  3. Streaming response appears under the canvas.

Status: backend proxy route drafted; UI alpha expected in two weeks.

2. Private Template Library

Problem: Freelancers and teams want to save custom mixes with zero limits.

Planned features

PlanCapability
Free (default)Unlimited templates & custom blocks locally; full CSV export
Optional cloud syncSign in to sync to encrypted Supabase tables, still free
CollaborationShare deep links without login

Status: database schema ready; RLS security testing underway.

Stay involved

Open to feedback via email at support@promptmix.io. All capabilities remain free—no hidden paywalls.


PromptMix is built in public—that means your requests shape our roadmap.
Until then, keep mixing and batching!
