Fireflies vs Otter vs Zoom AI Companion privacy checklist

A practical privacy and admin-control checklist for small teams comparing Fireflies, Otter, and Zoom AI Companion for meeting transcripts.

Published: Jun 13, 2026 Last reviewed: Jun 13, 2026 Audience: Small-team founders, operations leads, sales leaders, recruiting leads, workspace admins, and customer success owners choosing an AI meeting assistant Risk: Medium Evidence: Fireflies security and knowledge base documentation, Otter privacy/security and enterprise admin controls, Zoom AI Companion privacy/security documentation, Zoom meeting summary admin controls, and Cybergiz meeting-bot playbooks

Bottom line

Choose Zoom AI Companion first when your team already runs most meetings in Zoom and wants the simplest admin-controlled starting point. Choose Fireflies when you need a meeting assistant across multiple meeting platforms, CRM workflows, and stronger transcript workflow features. Choose Otter when live notes, collaboration, and workspace-level conversation management are the main need.

Do not choose only by transcription quality. For privacy, the decision should be:

Which tool gives the meeting owner, workspace admin, and data owner enough control over recording notice, transcript access, sharing, retention, and downstream integrations?

Before approving any of the three, run the AI Tool Risk Checker and record the decision in the Small Team AI Security Checklist. If your team is still deciding where transcript files should live, use the transcript storage policy first.

Quick recommendation

Team situation	Better default	Why
Most meetings already happen in Zoom	Zoom AI Companion	Fewer third-party joins, account/group/user controls, and meeting-summary settings live in the existing Zoom admin surface.
Sales or customer success needs cross-platform notes and CRM handoff	Fireflies	Stronger meeting assistant workflow and integration posture, but approve CRM and external sharing separately.
Team wants live notes and collaborative transcripts	Otter	Good fit when workspace conversation management and collaboration matter more than deep CRM workflow.
Recruiting interviews or HR meetings	None by default	Use only after consent notice, retention, access, and ATS sharing rules are written.
Regulated, legal, health, finance, board, incident, or acquisition meetings	Block lightweight approval	Escalate to the qualified owner before any bot joins or stores a transcript.
No admin owner or retention rule exists	Do not approve yet	Meeting transcripts become durable records; the owner must be named before rollout.

Privacy comparison matrix

Privacy question	Fireflies	Otter	Zoom AI Companion	Small-team decision
Best control plane	Fireflies workspace and meeting settings.	Otter workspace and enterprise admin controls.	Zoom account, group, user, and in-meeting controls.	Prefer the tool whose admin owner already manages the meeting workflow.
Recording consent	Meeting host/workspace must still provide notice and follow local law.	Otter states users must ask for consent and indicate recording/transcription.	Zoom meeting features can be enabled, disabled, locked, and surfaced in meeting controls.	Write a notice script regardless of vendor.
Training posture	Fireflies says meeting content is not used to train AI models and vendors operate under zero data retention terms.	Otter publishes privacy/security commitments, but teams should verify exact plan terms and data-use settings before sensitive rollout.	Zoom publishes AI Companion privacy/security documentation and admin controls for feature enablement.	Treat vendor claims as plan-specific evidence to record, not a substitute for policy.
Transcript access	Fireflies supports privacy settings, private meetings, secure external sharing, and admin governance features.	Otter enterprise controls include centralized conversation management, but admin access to transcript content may still require shared access from the owner.	Zoom summaries can be shared by role, restricted outside the organization, sent by email, protected through authentication, and auto-deleted.	Decide who can read raw transcripts, not only who can start the bot.
Retention	Fireflies documents admin governance and retention controls, with enterprise features such as Rules Engine and private storage.	Otter enterprise controls include custom data retention where conversations after the retention period are automatically deleted.	Zoom meeting summary settings include auto-delete after a set number of days.	Set default retention before enabling auto-join or auto-summary.
External sharing	Fireflies supports private visibility and password-protected external links with expiration controls.	Otter sharing must be governed by workspace policy and conversation permissions.	Zoom can restrict sharing summaries outside the organization and control email content vs authenticated link.	Block public links unless an owner approves a specific meeting type.
Integrations	Strong fit for CRM, calendar, and collaboration workflows, but every integration expands the data boundary.	Fit depends on workspace, calendar, and connected app settings.	Third-party application skills and knowledge collections need admin approval and source-system review.	Approve integrations separately from transcription.

Meeting type decision table

Meeting type	Default decision	Required controls
Internal weekly team meeting	Allow with notice	Private transcripts, limited retention, no external sharing.
Sales discovery call	Allow with notice	Customer notice, CRM sync approval, summary review before sending externally.

Rollout checklist

Run a two-week pilot before broad rollout.

Phase	Action	Exit criteria
Day 0	Pick one meeting category and one owner.	Owner, admin, retention, sharing, and notice are documented.
Day 1	Configure admin settings.	Auto-join, summary sharing, external links, and retention match policy.
Week 1	Pilot with 3-5 low-risk meetings.	No surprise bot joins, no unexpected sharing, summaries reviewed before external use.
Week 2	Review stored transcripts and integrations.	Owner can find, restrict, delete, and explain every generated record.
Expansion	Add one more meeting category at a time.	Each category gets its own notice and retention rule.

Red flags

Block or pause rollout when any of these appear.

The bot joins external meetings without the host expecting it.
Meeting invitees do not know recording or transcription is active.
Raw transcripts are shared with everyone by default.
CRM, Slack, Drive, email, calendar, ATS, or helpdesk sync is enabled without owner approval.
No one can explain how to delete a transcript or summary.
Employees use personal accounts for company calls.
Interview, HR, legal, security incident, or regulated-data meetings are included in the first pilot.
The team approves a tool because it is already popular, not because controls were reviewed.

FAQ

Is Zoom AI Companion more private than Fireflies or Otter?

Not automatically. Zoom can be the cleaner starting point when the team already uses Zoom because fewer additional vendors and joins are involved. Fireflies or Otter may still be the better workflow tool, but they need separate approval for calendar access, integrations, transcript sharing, and retention.

Which tool should a small sales team choose?

If sales calls happen across Zoom, Google Meet, and Teams, Fireflies may be more useful. If most calls are in Zoom and you only need summaries, start with Zoom AI Companion. Either way, approve CRM sync separately and require a human to review customer-facing summaries.

Which tool is best for interviews?

Do not pick a tool first. Write the candidate notice, decide whether raw transcripts are allowed, define the retention period, and approve ATS sharing. Then choose the tool that can enforce those rules with the least manual work.

Can employees use personal meeting-bot accounts?

No for company meetings. Personal accounts make offboarding, transcript discovery, deletion, and admin review much harder. Use a managed workspace or do not approve the workflow.

What is the minimum approval record?

Record the tool, plan, owner, meeting categories, consent notice, storage location, transcript retention, summary retention, sharing rule, integrations, and review date. Without that record, the meeting bot is not approved for business use.

Recommended next step

Pick one upcoming meeting category and fill out the vendor approval worksheet. If the team cannot answer the retention, sharing, and integration questions, keep the tool in a limited pilot and use the AI meeting bot consent and retention template before adding more users.
