Stop decision drift.

Simil picks up decisions in the tools you're already using as your team makes them, keeps the reason with each one, and says something when the work starts to drift. Nothing to fill in, nothing new to open.

Revise to 3 March

After testing, the design review and the campaign slot.
Keep 10 February
Say why, and Simil keeps your reason with the decision.
Revised before anyone built on 10 February. The context from Jira, Figma and Monday stays with the decision.

Puts 10 February at risk
Kept as context
One week on the product team we came from
200 decisions that week. 3 of them written down.

A quarter goes sideways and nobody can say why. Usually it was 30 small decisions across 6 tools over 3 months, each one sensible on the day, and none of them kept with its reason. By the time anyone notices, it has cost weeks of rework, budget nobody planned for and a deadline that has already slipped.

Every decision, where you left it.

Simil picks up decisions where they're made and keeps the reason with each one, so anyone can see what was agreed and why.

Search finds what was said. Simil knows why.

AI search tools look through your messages and tickets and hand back what matches. Simil keeps the decision itself: what was agreed, the reason, who agreed it and what it depends on.

Why isn’t v2 launching on 10 February?
AI search
I found 14 messages and 3 tickets that mention the v2 launch. Here are the closest matches:
“Can we push v2 a month?”
PLAT-212 · Launch date: 10 February
“Onboarding needs another round.”
Matching messages, no decision. You still have to work out what was agreed.
Simil
v2 moved to 3 March because onboarding testing wasn’t finished.
Why
People testing v2 kept getting stuck at sign-up.
Agreed
20 January in #product, by Maya Kessler
Holds while
Onboarding testing is still running
PLAT-212 now says 10 February. Maya has been asked.

Why did the launch move?

Ask Simil in whatever tool you're already working in. The answer comes back right there as the decisions behind it, in order, each with its date, source and reason.

Drift

The work has moved away from a decision. The owner chooses whether it still holds.

Conflict

Two decisions clash, or work is waiting on one.

Check-in

Its check-in date has come round. Does it still hold?

It works with what you already pay for.

Nothing gets migrated and nothing gets replaced. Simil starts in Slack, where most decisions get made, and asks the owner in the thread.

Ask Priya
Not a conflict
Everyone in #backend sees this reply. Priya has been asked whether the decision still holds.
For the director
Explain what changed across your department, and why.

Ask about your department and get one overview: each project, the decisions behind it, and their reasons. See what’s at risk before it slips, and share the overview with leadership as it is.

For the team
Confirm a decision once. Months later, the reason is still there.

Simil picks up decisions from your conversations and asks someone who was there to confirm. When a question comes up later, the answer comes back with who decided, when and why.
