Your next prompt, not your whole history.

Most chat apps send the entire thread. Yokolo sends the part that matters. Tag a message, switch a tag out, and watch two models answer the same reduced context.

40-second walkthrough

Tag → exclude → compare

What you are looking at

One workspace, two answers, less noise.

The left panel is the transcript. The tags are the control surface. When you send, you choose which tags are in scope — so the prompt is assembled, not inherited.

Tag whole messages or a highlighted sentence.
Exclude a tag without deleting the message.
Send the same context to two models.
Keep the comparison as part of the record.

Built for deliberate prompting

Less context, better answers — and you can prove it.

Reducing context is easy to claim and hard to verify. Yokolo keeps both sides: the message you excluded and the answer that followed, so the decision stays auditable.

Tag the evidence

Decisions, constraints, quotes and examples become labels you can include or drop per prompt.

Assemble the prompt

Pick tags, or anchor a context window to a range of text. Edits don't break the window.

Compare the result

Run one prompt across several models. Keep the answer that used the context best.
