What changes
Your week, without and with Obsidian.
Before
Without Obsidian
- Consolidated texts read line by line to find the difference
- A press release mistaken for a rule already in force
- Application dates copied by hand, and sometimes wrong
After
With Obsidian
- The difference isolated, field by field
- A clear status: Sourced, or Announced, not yet official
- The effective date and the official source, one click away
The benefits
What you gain, in concrete terms.

What changed, in one line
Obsidian isolates the change: the old rule, the new one, and nothing else. No more full rereads.

Obsidian Regulatory Change Analysis compares each version of a regulation and shows, field by field, what changed, when it takes effect and whether the change is official or only announced.
Where do the before and after come from?
From the official text, version by version. Every change links to the source behind it.
What does "announced, not yet official" mean?
An announced change (a proposal, a consultation, a press release) is not yet a published rule. Obsidian tells it apart from a change sourced in the official journal.
Can I see only what concerns me?
Yes: the feed filters by topic, by jurisdiction and by entity.
What comes next?
Every change feeds the impact assessment: for each entity affected, the impact level and the next step.
