ThreadKiller extracts every decision, owner, and unresolved question from your email thread, then drafts a confirmation reply before someone acts on the wrong version. No inbox access required.
Paste your thread and get your analysis instantly. No account to create, no confirmation email, no barrier between you and your answer.
We never ask for access to your email account. You choose exactly what to share by copying and pasting: nothing else is ever visible to us.
Your thread content is gone the moment your analysis is complete. We do not retain it, log it, or use it for any other purpose.
Run this before replying to important project or client emails.
Private by design: paste only what you choose, process it, move on.
Takes about 15 seconds
Analyzing your thread with smart extraction...
Upgrade to Pro for AI-powered analysis that goes deeper into every thread.
Unlike Copilot or Gemini, ThreadKiller works on any email: no connection to your inbox.
Most teams don't realise how many decisions live inside email until they map one out. This is where project misalignment usually starts.
ThreadKiller never connects to your email account, sees your inbox, or stores your messages. You paste the email text yourself, the analysis runs, and nothing is saved anywhere. Your emails stay entirely private.
ThreadKiller is built for threads where decisions, responsibilities, or commitments are being discussed: project updates, client briefs, scope conversations, approval chains, and anything where "who said what" matters. The messier and longer the thread, the more useful the output.
Summarisation tells you what was said. ThreadKiller tells you what was decided, who owns it, what is still unresolved, and drafts a confirmation reply you can send immediately. It is built for accountability and action, not reading convenience.
You can, but you would need to know exactly what to ask, how to frame it, and how to interpret a freeform response that changes every time. ThreadKiller is a purpose-built tool: the prompting, the structure, and the output format are already done for you. You get consistent, actionable results every time: decisions, owners, open questions, and a ready-to-send confirmation reply, without having to engineer a prompt or piece together an answer yourself.
Not to try it. Paste a thread and run an analysis, no signup required. Upgrade to Pro or Business for better functionality.
After your thread is analysed, ThreadKiller drafts a short professional email confirming the decisions and responsibilities it identified. You copy and paste it into your own email client. Nothing is sent automatically, you always decide if and when to send it.
Anyone who finds long email threads overwhelming, loses track of what was agreed, or needs a clear record of who said what. Agencies, consultants, project managers, recruiters, account managers, healthcare, financial services, insurance, B2B marketing, media, publishing, and e-commerce. If you regularly end up asking "wait, what did we actually agree?" this is for you.
The text you paste is sent securely to the AI model for analysis and is not stored on our servers. We do not log thread content, sell data, or use your inputs to train any model. Once the analysis is complete, the content is gone.
