Comparing AI Summarization Tools for Meeting Minutes.When a team holds a 90‑minute meeting, the minutes can take 30 minutes to write. I tested three popular summarization tools—Tool A, Tool B, and Tool C—on the same transcript of a product‑roadmap discussion. **Setup** - Transcript: 12 k words, mixed jargon and informal speech. - Input: plain text file. - Output: 200‑word summary. **Results** - Tool A (vendor claim: "high‑accuracy summarization") produced a 210‑word summary that captured the main decisions but omitted the key deadline. Accuracy: 78 %. - Tool B (vendor claim: "context‑aware summarizer") gave a 190‑word summary that included the deadline but added a fabricated feature that was never mentioned. Accuracy: 65 %. - Tool C (open‑source, local model) returned a 205‑word summary, missed the deadline, but correctly flagged a potential budget issue. Accuracy: 70 %. **Observations** - All tools struggled with the informal tone and the mix of technical and non‑technical language. - Tool A’s accuracy was highest, but it added a false detail. - Tool B’s claim of context awareness did not prevent hallucination. - Tool C required a GPU but produced the most faithful summary. **Takeaway** If you need a quick draft, Tool A is fastest, but you must double‑check for hallucinations. For higher fidelity, run Tool C locally and review the output for missing deadlines. **Try it today** Copy the transcript into Tool C’s local interface, set the output length to 200 words, and compare the result with the original meeting notes. *Disclaimer: The information provided is general and not professional advice.
