Run StepFun: Step 3.5 Flash in an invisible overlay that listens to your meetings, sees your screen, and answers before you need it — no stepfun account, no API keys.
The actual overlay running StepFun: Step 3.5 Flash — live scenarios, real UI. Always on top of every app, invisible on screen shares.
The same overlay, two ways to use it — and StepFun: Step 3.5 Flash is one tap away in both.
An error, a contract, a chart, an email — capture the screen, drag-select a region, or attach documents with built-in OCR, and StepFun: Step 3.5 Flash reads it all. Turn on Use image and every message carries a fresh screenshot automatically.
Pluely transcribes your mic and system audio in real time, and StepFun: Step 3.5 Flash drafts the answer before the question even finishes — automatically on every question, after each pause, or only when you tap Suggest.

Open the overlay's model picker, search for StepFun: Step 3.5 Flash, and your next question runs on it. No stepfun account, no keys to manage — it's bundled with your Pluely plan, and you can switch models mid-conversation.
The overlay never shows up in screen shares, recordings, or screenshots, and no bot joins your calls. Your chats, meetings, and files stay in a local, encrypted database on your device.
No stepfun account, no API key, no setup ritual.
Click the model picker in the bottom-right corner of the overlay's composer.
Tap it in the list — it's bundled with your plan, so there's nothing to connect or configure.
Your next answer runs on StepFun: Step 3.5 Flash, and you can switch again mid-conversation with context intact.
StepFun: Step 3.5 Flash is one of the models bundled with Pluely Pro: available in the overlay's picker with zero setup, and switchable mid-conversation. Here's how stepfun describes it:
Step 3.5 Flash is StepFun's most capable open-source foundation model. Built on a sparse Mixture of Experts (MoE) architecture, it selectively activates only 11B of its 196B parameters per token....
Install Pluely and it's one tap away — for the next error, the next call, the next thing you'd rather not figure out alone.
