How Sivolo works — from messages to evidence

Export your messages

Use your phone’s built-in export to save a chat from WhatsApp or Android SMS, or simply paste the text — including from iMessage.* Long histories are handled automatically by splitting them into date ranges.

* Note on iMessage: iMessage has no one-tap chat export. You can copy and paste messages straight into Sivolo, or use a reputable third-party export utility to produce a text file. WhatsApp and Android SMS both export natively from the app.

Add a little context (optional)

Tell Sivolo who is who, the type and length of relationship, and any key dates or incidents. Context sharpens the analysis but is never required, and is stored only on your device.

Sivolo analyses the conversation

The conversation is assessed against Section 76 of the Serious Crime Act 2015 and CPS statutory guidance on coercive and controlling behaviour. Large logs are read in passes, then reconciled into one picture.

Review your results

Findings are grouped into four evidence lenses with the exact messages, timestamps and a plain-English explanation of why each one matters. You can add notes, see surrounding context, and flag anything.

Learn what you’re looking at

A built-in education library explains coercive control, reactive abuse, trauma bonding and recovery in plain language — curated, not generated, so you can trust what you read.

Export and share, safely

Produce a professional PDF report for police, an IDVA or a solicitor — or securely share specific findings with a trusted contact. You stay in control of who sees what, and can revoke access at any time.

The evidence model

Four lenses on the same conversation

Coercive control is a single pattern, but the law asks several different questions about it. Sivolo answers each one separately so the picture is complete — and so the same message is never double-counted.

Reactive abuse

Were you provoked into a reaction?

Shows the other party’s provocation — a threat, an accusation, a coercive demand — paired side by side with your response. This protects a defensive reply from being read in isolation and misused as “evidence” you were the aggressor.

High-value admissions

What did they admit in their own words?

Surfaces moments where the other party admits intent, awareness or control — “I did it to punish you”, “I knew that would hurt you”, “you’re not allowed to see them.” Direct evidence, in their own hand.

Victim impact

What effect did it have on you?

Identifies fear, compliance, walking-on-eggshells language and normalisation — the cumulative psychological harm that the law treats as the serious effect at the heart of the offence.

Pattern categories

Which recognised patterns appear?

Scores established patterns — monitoring, isolation, degradation, threats, DARVO, coercive ultimatums, manufactured jealousy, love-bombing — by how pervasive each one is across the whole history.

Scoring, in plain English

How a pattern becomes a score

Each pattern category is scored from 0–100 based on how often it appears and how serious each instance is — not a simple count. Two conversations of the same length can score very differently.

Absent — no evidence found
Low (1–39) — one or two minor instances
Medium (40–64) — a repeated pattern
High (65–84) — multiple serious instances
Critical (85–100) — severe and pervasive

An overall risk level reflects the strongest categories — and where several independent patterns each reach High, the sustained, multi-strand nature of the control is itself treated as a serious-harm signal.

The pattern categories are drawn from the Crown Prosecution Service statutory guidance on Controlling or Coercive Behaviour — the same framework police and prosecutors use to assess these offences in England & Wales — so every result maps to a recognised legal reference point.

Sivolo organises and evidences material against the legal framework. It does not reach legal conclusions or diagnose anyone — that remains for qualified professionals and the courts.
