THE END OF RESEARCHING THE SAME THING TWICE

You've had the conversations.
Where are the decisions?

Turn a ChatGPT or Claude history export into a source-linked register of decisions, rejected ideas, open questions, and next actions. Review every finding before you trust it.

Free to use. It makes mistakes. DecisionTrail finds candidates with keyword rules, not AI, so it misses some decisions and marks some sentences wrongly. Treat every item as a draft and check it against the linked chat. Your files are read in your browser and never uploaded.
