Is There an App That Checks Texts From Your Ex for Manipulation or Gaslighting?
Reviewed by Jacob Reed, founder of Verity · ·
Short answer
Yes. Some read a few messages you paste in and name the tactics, such as DARVO.app, Tether, Gaslighting Check and Verity's free text check. Others read a whole exported conversation and organize it for review, such as Textimony, Dispute Buddy and Verity. Before you choose, check where your messages go, whether every message keeps its sender and date, and what you could hand a lawyer. No app can tell you what someone meant, or whether a court will accept what it found.
When a conversation leaves you doubting your own memory, it is natural to want a second reader. Several tools now offer one. They are built for different moments: making sense of one message tonight, or organizing months of messages before a hearing.
What kinds of apps are there?
1.Checkers you paste a few messages into
You copy a message or a short thread into a box and get the tactics named, often with a plain-language translation and ideas for a reply. DARVO.app works this way: a free tier with no account, and a $14.99 a month plan that saves your analyses. Its security page says pasted text goes to its server and is read by Anthropic's Claude to produce the result, and is not used for training. Tether is free and anonymous: you paste messages and can add a short safety checklist. Its site says messages are not stored or shared and that the analysis runs through Hugging Face. Gaslighting Check takes pasted text, screenshots or audio recordings and charges in tokens per analysis; its site says pasted text stays on your device until you create an account, and that you can ask for what you sent to be deleted. Verity also has a free text check: no account, and it runs in your browser, so what you paste is not sent anywhere. See DARVO.app vs. Verity and Tether vs. Verity.
2.Tools that read the whole conversation
You give the tool an export of the entire conversation, and it looks for patterns across all of it with each message's sender and date kept. Textimony is a sign-in workspace: you import an export, the analysis runs on its servers, and you accept or dismiss each flagged item before building a report. It is free for a limited time. Dispute Buddy pulls a conversation from an iPhone or an OurFamilyWizard account and produces a behavior report. Verity reads an export or screenshots in your browser, so the conversation is not uploaded. See Textimony vs. Verity and Dispute Buddy vs. Verity.
3.Co-parenting apps
OurFamilyWizard, TalkingParents and similar apps hold the messages themselves, on a record both parents use, and some warn you about harsh wording before you send. They help with messages from now on, not with texts already on your phone. See court-ordered co-parenting apps, compared.
What should you check before you share your messages?
- Where your messages go. Most paste-in checkers send what you paste to their server, and often on to an AI company. A workspace keeps your upload on its servers. Read the privacy or security page, and look for whether you can delete what you sent.
- How much it reads. One message rarely shows a pattern. Blame-shifting, reply demands or threats matter because of how often they happen, which only shows across weeks and months of messages.
- Whether senders and dates survive. A list of tactics with no dates is hard to use. Look for results that keep who sent each message and when.
- What you can hand your lawyer. Most lawyers want the messages themselves, in date order, more than a score. Keep the original export, and the phone, whatever tool you use.
- What it says it can’t do. A careful tool says plainly that it does not diagnose anyone and is not legal advice.
- Your safety. If someone may check your phone or computer, use a private window, and think twice before installing an app whose icon they could see. Several of these sites, Verity included, have a quick-exit button.
What can't any of these apps do?
They read words, not people. Sarcasm, an inside joke, missing context or an ordinary argument can look like a warning sign, and abuse worded politely can slip past. Our own testing found the same thing: much real abuse is worded in ways a pattern check misses. No app can tell you what someone intended, diagnose a personality disorder, or say whether a court will admit or trust the result. Treat what an app flags as a list of messages to reread, with your lawyer if you have one. Our methodology page sets out what Verity measured and where it falls short.
Where does Verity fit?
Verity is for the second moment: months of messages and a lawyer or hearing ahead. You export the conversation, or pick screenshots, and it is read in your browser, so the messages are not uploaded. The free preview shows the patterns found across the whole conversation and one flagged message in full. Paid options are one-time: a numbered list of every message in date order ($19), or a report quoting the flagged messages with their dates, which comes with the numbered list ($99 Standard, $149 Detailed). The numbered list records a SHA-256 fingerprint of the original export file, so the file can later be checked against it. Verity can't read a conversation you have no export or screenshots of, and times read from screenshots are estimates.
Which kind should you pick?
- One message you can't make sense of: a paste-in checker gives you words for what it is doing, and help replying.
- Months of messages and a hearing ahead: a tool that reads the whole conversation and keeps every date.
- You don't want the conversation on anyone's server: check that it is read on your own device. Verity is built that way.
- You still message the other parent: a co-parenting app keeps future messages on one record.
