The Verdict

Otter and Slack aren't really competitors — Otter transcribes meetings, Slack runs team communication. Most small teams end up using both, connecting Otter's meeting summaries directly into a Slack channel via its native integration. If you're forced to pick one, choose Slack first since it's the daily hub; add Otter only once meeting notes become a real pain point.

How to switch from Otter.ai to Slack

1Export existing Otter transcripts: open each conversation and use Export > choose TXT, PDF, DOCX, or SRT format, downloading important meeting notes before any plan changes or cancellation.
2Create your Slack workspace and set up channels that mirror your team's structure (e.g., #general, #meetings, #projects) so conversations have a clear home.
3Reconnect Otter to Slack via the official integration (Settings > Integrations in Otter) so meeting summaries keep posting automatically into the right channel instead of losing that workflow entirely.
4Recreate any automations you relied on in Otter (like auto-sharing summaries to email) using Slack's Workflow Builder or Zapier/Make connections.
5Migrate other integrations — Zoom, Google Calendar, Google Drive — into Slack one at a time, testing each before removing it from your old setup.
6Set a cutover date, archive old Otter transcripts for reference, and have the team start posting and searching exclusively in Slack from that date forward.

Otter.ai vs Slack: common questions

How do I export my data from Otter before switching tools?+

Open any conversation in Otter and use the Export option to download transcripts as TXT, PDF, DOCX, or SRT subtitle files. There's no bulk export for all transcripts at once on lower tiers — Business and Enterprise plans support API access for bulk pulls. Export conversations individually if you're on Free or Pro before canceling.

What do I lose if I switch from Otter to Slack?+

You lose automatic meeting transcription and AI-generated summaries entirely — Slack has no native equivalent. You'd need to pair Slack with a separate transcription tool (including Otter itself, via its Slack integration) to replicate that functionality.

Is Slack's free plan enough for a small team?+

For teams under 10 people with light usage, yes — but the 90-day message history limit and 10-integration cap are real constraints. Teams relying on searchable long-term history or multiple app integrations (like Otter, Jira, and a CRM) will hit the ceiling fast and need Pro at $7.25–$8.75/user/month.

Does Slack integrate with Otter.ai directly?+

Yes, Otter has a native Slack integration that posts meeting summaries, transcripts, and action items directly into a chosen channel after each meeting. This is the most common setup — teams don't actually replace Otter with Slack, they run both together.

How does the cost compare over a year for a 10-person team?+

Otter Pro for 10 users runs about $2,038/year ($16.99 x 10 x 12), while Slack Pro costs roughly $870/year billed annually ($7.25 x 10 x 12). Running both tools together costs around $2,908/year for a 10-person team — budget for both if transcription and chat are both must-haves.
