Every change,
fully versioned.

Every save creates a real, append-only version of your intent — prompt, schemas, guardrails, and execution config. Compare any two versions with a GitHub-style diff, and restore a prior version in one click.

Versioning

Ship changes without fear

01

Append-Only History

Every save creates a new version — nothing is overwritten. Your intent's full history is always there, from the very first draft.

02

Field-Level Diffs

See exactly what changed between any two versions — prompt text, schemas, guardrails, execution config — line by line.

03

GitHub-Style Diff View

Added lines highlighted green, removed lines struck through in red. The same diff language your engineers already read every day.

04

One-Click Restore

Roll back to any prior version instantly. A restore is itself a new version — always reversible, never a dead end.

05

Cross-Intent Version Feed

See every change across every intent in one combined, filterable timeline — not just one intent at a time.

06

Zero-Risk Iteration

Ship a prompt change with confidence. If it doesn't work out, you're one click from exactly where you started.

Lifecycle

Save, diff, restore

Three primitives cover the full lifecycle of a change — from the moment you save it to the moment you might need to undo it.

Save
Every change

Every explicit save creates a new, immutable version — prompt, schemas, guardrails, and execution config captured in full.

Change review

Compare any version against its predecessor — or any two versions against each other — with a field-level, line-by-line diff.

Safe rollback

Roll back to any prior version in one click. The restore itself becomes a new version — always reversible.

One click
step
Walkthrough

A prompt tweak makes things worse — reverted in one click

A team adjusts a scoring intent's reasoning mode to improve accuracy, ships it, and watches confidence scores drop instead. The diff against the prior version shows exactly what changed.

One click restores the previous version — itself logged as a new entry in the history, so the failed experiment isn't lost, just reverted.

FAQ

Common questions

Yes — every explicit save is a new, immutable version, whether it's a one-word prompt tweak or a full schema rewrite. There's no manual "commit" step to remember; it's automatic.

The full intent definition — prompt text, input/output schemas, guardrail policies, and execution config — captured together, so a version always represents a complete, working configuration.

Nothing destructive. A restore itself creates a new version rather than deleting history, so you can always restore forward again — there's no dead end.

Yes, the cross-intent version feed shows every change across every intent in one combined, filterable timeline — not just one intent's history at a time.
