Fathom joins meetings as a visible participant that all attendees can see. The bot's presence can feel disruptive and makes participants self-conscious about being recorded. The bright yellow 'Monologue Detection' pop-up interrupts conversation flow. Many users express discomfort with its visible presence.

Users report timestamps are extremely inaccurate - a 2-3 hour Zoom call showed timestamps as if the call was only 6 minutes. This makes it difficult to navigate to specific parts of meetings and undermines the usefulness of the transcript archive.

The AI summary can jumble the flow, mix up tasks, and make conversations look scattered. This potentially makes external recipients assume the conversation wasn't well-organized. The perspective of summaries often needs modification before sharing with customers or teams.

The bot takes up a window of its own on Zoom calls, which can end up in a breakout room making it ineffective. This disrupts meeting flow when the bot accidentally gets assigned to breakout sessions, missing the main conversation.

Transcriptions aren't 100% perfect, especially with background noise or multiple speakers talking over each other. The AI occasionally gets spellings wrong, mishears words, and mislabels platforms (CLIO labeled as LAWMATICS). Manual corrections are still needed.

Users find summaries lack detail and customization control is limited. The AI doesn't always know what to emphasize. Important nuances from meetings are often missed, requiring users to review full transcripts anyway rather than relying on AI summaries.

The 'your questions' feature produces sentences that don't correspond to what was said. Question assignments aren't always correct. Users find this AI feature unreliable and end up ignoring it, reducing the value of the automated meeting analysis.

While recordings are unlimited, AI summaries, action items, and advanced features are limited to just 5 meetings per month on the free plan. Users quickly exhaust this limit and must upgrade to Premium at $15-19/month for unlimited summaries. The 'unlimited free' marketing is misleading.

Fathom does not have a mobile application as of 2025. This limits utility for in-person discussions since users need a PC present. Teams that conduct a mix of remote and in-person meetings find this restriction frustrating and need workarounds to record face-to-face conversations.

One user reported that Fathom caused significant damage to their company as they no longer have access to transcripts and files for several long-term client relationships. Loss of historical meeting data can be devastating for businesses relying on meeting archives.

Users report the bot crashes every meeting which is distracting. Others report the bot keeps leaving and joining meetings repeatedly. The company acknowledged the issue but users say they were just told the team was 'aware of it' without resolution.

Users report increased issues with CRM sync. One user reported that after 16 emails and a week and a half, nothing had been resolved. Customer support isn't always reliable for integration problems, leaving users unable to sync meeting data with their sales tools.
