Conditional Text Switch

The job

Conditional Text Switch picks between two strings based on the parity of a number. Odd → text_odd. Even → text_even. That's it - the whole node is an if statement with text on both branches, sitting under the "Conditional Text Switch" name in the ProtoTeller category.

Why it exists

Same family, same trick as its siblings in this pack: a tarot draw lands either upright or reversed, and the two readings are genuinely different texts. ConditionalTextConcat builds one string and conditionally appends a tail; this node is for when the branches are whole, different strings. Keep the full upright and reversed readings as separate strings, switch between them on the draw's parity, and you never have to assemble or split anything.

Inputs and output

• text_odd - returned when number is odd.
• text_even - returned when number is even.
• number - INT, 0–100.
• Output: one STRING, whichever branch won.

The one thing to keep straight

The polarity doesn't line up across the pack, and it's worth noticing: ConditionalImageRotate flips on even, ConditionalTextConcat appends on even, and this node returns text_odd on odd. There's no "invert" flag. If you wire one number into all three and get a card whose flipped title and switched text disagree, check which field you dropped the reading into - the parity convention is the author's, not the universe's.

Wiring it

STRING out → into your LLM prompt builder or the text input of PreviewTextImage. Feed number from the same source as the other conditionals so a single draw drives the image flip, the text switch, and the concat in lockstep. Swap the two inputs to invert the behavior without touching the number.

Install

Same as the rest of the pack: ComfyUI Manager → search "ProtoTeller", or

cd ComfyUI/custom_nodes
git clone https://github.com/DoctorDiffusion/ComfyUI-ProtoTeller

then restart. No models, no extra dependencies - like the rest of the conditional utilities in this pack, it runs on core Python with nothing downloaded.
