Zero-friction workflow

Three keystrokes between raw and refined.

01
⌘C

Copy

Select any code, raw prose, or messy data anywhere on your Mac and hit Copy. Your clipboard is the input.

02
⌥Space

Trigger

Summon Transfo's menu-bar panel instantly over the active window. Focus never leaves — no app switch, no modal.

03
1–5

Paste

Pick a Recipe with a number key. Content streams through the pipeline and auto-pastes back as refined Rich Text or code.

10 built-in recipes

Pick a recipe. Watch it transform.

Each recipe is a tuned, deterministic pipeline — no prompt engineering, no chat. Streams to your BYOK provider with automatic failover across OpenRouter, Gemini, and OpenAI.

Data handling

Your data never leaves your RAM.

Architected like a system utility, not a SaaS. The pipeline is the product — we don't need a copy of your content to operate it.

Apple Intelligence runs on-device
On macOS 26+, eligible prose recipes (Summarize, Rewrite, Explain, Grammar, Translate, Action Items) execute locally — your text never leaves the Mac.
Clipboard read on hotkey only
Transfo reads the clipboard at the precise millisecond ⌥ Space fires. No background monitoring, no polling.
API keys live in Keychain
Your OpenRouter, Gemini and OpenAI keys are stored in macOS Keychain — not plain text, not UserDefaults, not synced to us.
No persistent history, zero telemetry
Transformed text is dropped the moment it leaves your clipboard. No prompt log, no usage tracking, no content payloads.
Direct end-to-end HTTPS
Remote calls stream straight to your configured OpenRouter / Gemini / OpenAI endpoint with your key. Transfo has no intermediate server in the path.
Clipboard never overwritten on error
Validation guards every output. If the AI fails or returns junk, your original clipboard is preserved — and ⌘⇧Z restores it within the undo window.

Transparent BYOK pricing

Free, in the way utilities used to be.

No usage caps from us — your provider, your key, your bill. Pro unlocks the heavier recipes and a wider undo window.
