Gemini History Analyzer

Unpacks your Google Takeout Gemini export, classifies every conversation, and produces a structured insight report.

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

What it does

Turns a raw Google Takeout ZIP of your Gemini Apps activity into a readable analysis.

  • Extracts with unar so Chinese/Unicode filenames don't get mangled (macOS unzip silently corrupts them)
  • Builds a full inventory (file counts, sizes, types) and samples 3–5 files to detect conversation type: meeting transcripts vs. prompt-response
  • Classifies topics (software, AI tooling, infra, business, finance, legal, personal…) and summarizes each file
  • For domain keyword hunts it treats grep as step one only — every match gets ±10 lines of context read to kill false positives
  • Flags PII (resumes, background checks) without copying the sensitive content into the report
  • Emits a structured Markdown report with distribution tables, key findings, and verbatim quotes; optionally writes project memory files
  • Fans out to parallel sub-agents for 100+ file archives so context doesn't blow up

Who it's for

  • Long-time Gemini users who want a retrospective on what they actually discussed
  • PMs and team leads who uploaded meeting transcripts into Gemini
  • Anyone building a personal profile of interests and workflows from real data
  • People auditing whether their chat history leaks sensitive info

Examples

  1. Full overview — "Analyze this takeout.zip" returns conversation counts, language mix, a topic distribution table, and top findings.
  2. Domain search — "Find anything about investing or stocks" runs keyword batches, then context-verifies each hit so dev-context words like 'option' or 'fund' get discarded.
  3. Memory building — "Remember my working preferences from this" generates user-profile.md and updates the MEMORY.md index with a source tag.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the gemini-history-analyzer folder from the GitHub repo daymade/claude-code-skills into my ~/.claude/skills/gemini-history-analyzer/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/daymade/claude-code-skills.git && mkdir -p ~/.claude/skills && cp -r claude-code-skills/gemini-history-analyzer ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open your terminal.
  2. Make the skills directory: mkdir -p ~/.claude/skills
  3. Clone the repo: git clone https://github.com/daymade/claude-code-skills.git
  4. Copy just this skill: cp -r claude-code-skills/gemini-history-analyzer ~/.claude/skills/
  5. (macOS) Install the extractor: brew install unar — the built-in unzip corrupts non-ASCII filenames.
  6. In Google Takeout, select only 'Gemini Apps' and download the ZIP.
  7. Restart Claude Code and say "Analyze this Gemini takeout zip" with the path to your ZIP file.
  8. When the report is done, Claude asks whether to delete the temporary extraction folder — deleting it is recommended for privacy.
