Gemini History Analyzer

Extracts and analyzes Google Takeout exports of your Gemini chat history, producing a topic breakdown, key insights, and PII warnings.

Data & AnalyticsIntermediate★ 1,323⑂ 212AI score 9/10Last updated: Aug 8, 2026

What it does

  • Extracts the Google Takeout 'Gemini Apps' ZIP with unar, avoiding the macOS unzip bug that mangles Unicode/Chinese filenames.
  • Builds a file inventory by type and size, then samples 3-5 transcripts to decide whether the data is meeting transcripts or prompt-response logs.
  • Classifies each conversation by topic (dev, AI/LLM, infra, business, finance, legal...) and pulls out discussion points, decisions, and verbatim quotes.
  • Runs domain keyword searches with AND/OR logic, then mandates ±10 lines of context verification to kill the huge false-positive rate grep alone produces.
  • Flags PII (resumes, background checks, contact lists) by risk level without copying the content into the report.
  • Emits a 7-section analysis report and can optionally write project memory files.

Who it's for

  • Anyone wanting a readable summary of years of Gemini chat history
  • Team leads and PMs who upload meeting transcripts into Gemini
  • People curious about their own AI usage patterns and interest domains
  • Privacy-minded users auditing an export for sensitive data

Examples

  1. "Analyze takeout-20250101.zip" → report with file stats, conversation type, and a topic distribution table.
  2. "Find any finance or investment discussions in my Gemini history" → batched keyword grep plus context verification that separates real hits from false positives.
  3. "Turn this analysis into a user-profile memory file" → writes user-profile.md and updates the MEMORY.md index.
