Zero-friction workflow

Three keystrokes between raw and refined.

Slack · #design-review⌘C

hey team — users said the checkout button color blends into the background and they missed the free shipping banner entirely, also the coupon field is hidden below the fold on mobile can someone write this up properly?

01
⌘C

Copy

Select any code, raw prose, or messy data anywhere on your Mac and hit Copy. Your clipboard is the input — no app to open, nothing to upload.

Transfo · Recipes⌥Space
click or ↑↓ · ⏎ run · esc close
02
⌥Space

Trigger

Summon Transfo's panel over the active window and pick a recipe with a number key. Focus never leaves — no app switch, no modal, no chat.

Linear · New issueready to paste
[HIGH] Checkout button lacks contrast — users miss the primary action
[MODERATE] Free-shipping banner not noticed — move above product grid
[MODERATE] Coupon field below the fold on mobile — surface in order summary
03
⌘V

Paste

The result streams through the pipeline and lands in your clipboard as Rich Text or code. Press ⌘V wherever you are — a tracker-ready report in the time it takes to switch tabs.

Recipe catalog

30 recipes across 8 categories.

8 free forever, 22 with Pro. From a commit message to a blameless postmortem — one hotkey, no chat window.

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.

Hotkey-only read
The clipboard is read at the millisecond ⌥Space fires. Never before, never in the background.
RAM-only
Content lives in volatile memory for the duration of the transform. Nothing is written to disk.
Zero logging
No prompt history, no transform log, no telemetry payload that includes your content. Ever.
Direct HTTPS
Streams straight to your configured provider with your key. Transfo's servers are not in the path — there are none.
