The Bacham Advantage

Why professionals and students are kicking out meeting bots

Stop sending awkward bots to client calls. Capture notes with dual-stream clarity, zero monthly fees, and 100% local privacy.

NO BOTS100% BANNED

Traditional Cloud Bots

Otter, Fireflies, Grain, etc.

Awkward Uninvited Meeting Bots

A bot enters your Zoom/Meet call with an obnoxious banner, alerting clients and peers they are being recorded.

Wall-of-Text Unstructured Transcripts

Leaves you with thousands of lines of unedited speech with zero actionable takeaways or study retention.

Confidential Data Uploaded to Cloud

Sensitive executive decisions, IP, and customer secrets are sent to third-party servers for model training.

Recurring Per-Seat Monthly Taxes

Expensive subscriptions of $20–$40 per user every single month with strict recording minute caps.

Result: Client friction, recurring bills, third-party privacy leaks.

Frequently asked questions

Everything you need to know about Bacham's privacy model, local AI engine, and extension integration.

No. Unlike legacy cloud tools (Otter, Fireflies), Bacham never sends an uninvited bot to your call. It records directly through your operating system's native audio loopback (WASAPI on Windows, CoreAudio on macOS) or via the Chrome Extension for browser tabs. It is 100% invisible to other participants.
