The tools at a glance

Here's a quick summary of each tool's core identity before we get into specifics.

Pricing comparison (2026)

Most AI meeting tools charge per seat, which adds up quickly for teams. Relay Digest uses flat-team pricing.

Tool Relay Digest Otter.ai Fireflies tl;dv Grain
Pricing modelFlat teamPer seatPer seatPer seatPer seat
5-person team / month$15$85$90$145$95
10-person team / month$25$170$180$290$190

Note on per-seat tools: Otter.ai, Fireflies, and tl;dv all offer generous free tiers with limited monthly minutes. If you're an individual with light usage, those free tiers may be all you need. For teams of 3+ who record regularly, Relay Digest's flat pricing is substantially cheaper.

Best AI meeting tool for Plaud device users

Relay Digest is the only AI meeting tool with native Plaud integration. Every other tool requires a meeting bot, a Zoom recording export, or a manual upload workflow.

With Relay Digest and a Plaud device:

Otter.ai has a mobile app that can record in-person meetings, but it lacks Plaud sync, voice embedding-based speaker ID, and the team intelligence layer. For Plaud users, Relay Digest is the purpose-built choice.

Best for proactive team alignment: Morning Brief

All five tools build a searchable archive of your meetings. Only Relay Digest pushes you toward action every morning.

The Morning Brief is a daily personalized digest generated by GPT-4o that includes:

This is the core difference between Relay Digest and the other tools: it's designed to change behavior, not just store information. The other tools are passive archives — you get out what you put in, and only when you go looking. Relay Digest proactively surfaces what you need to act on.

Who should use what

Best for
Relay Digest — Plaud users, small teams, operators who record everything

If you use a Plaud device, record in-person meetings or phone calls, or want a daily brief that keeps your team aligned, Relay Digest is the only tool built for your workflow. Also the best value for teams of 3–20 people.

Good for
Otter.ai — individuals, live transcription, lightweight teams

Best for real-time transcription during calls and individuals who don't need team knowledge management. The free tier is generous. Starts feeling expensive when you add teammates.

Good for
Fireflies.ai — sales teams with CRM workflows

If your primary need is syncing meeting notes to HubSpot or Salesforce automatically, Fireflies handles this better than anyone. Less useful for general team intelligence or non-sales workflows.

Good for
tl;dv — async-first teams, coaching, clip sharing

Best for teams that want to share video clips from meetings — coaching, async reviews, onboarding. If you're primarily text-and-action oriented, it's overkill.

Skip if
Grain — only makes sense for video sales coaching

Grain is strong for video highlight reels and sales call coaching. Outside that specific use case, it's weaker than the alternatives on AI features, team search, and pricing.

Frequently asked questions

Does Relay Digest require a Plaud device?

No. Relay Digest works with any audio source — upload MP3, M4A, WAV, MP4, OGG, or WebM files up to 25MB. Zoom recordings, Google Meet exports, phone recordings, and in-person meetings all work. The Plaud integration is a bonus for Plaud owners.

How is Relay Digest different from Otter.ai?

The core difference is philosophy. Otter.ai is a passive archive — it stores your transcripts and you search when you need something. Relay Digest is proactive — it delivers a Morning Brief every day, tracks overdue commitments in a Worry Report, and builds a knowledge graph of relationships across all your recordings. Relay also doesn't require a meeting bot and has native Plaud support. Otter.ai has a stronger free tier and better live transcription.

How is Relay Digest different from Fireflies.ai?

Fireflies is built for sales teams with CRM workflows — if you need meeting notes auto-synced to Salesforce or HubSpot, Fireflies is ahead. Relay Digest is built for general team intelligence — morning briefs, knowledge graphs, people profiles, and commitment tracking. Relay also doesn't require a bot, supports Plaud sync, and is significantly cheaper for teams.

What is the Morning Brief and does any other tool have it?

The Morning Brief is a personalized daily AI digest that includes a situation summary, your top 3 priorities, and overdue action items. It's generated each morning by GPT-4o and can also be triggered on demand. No other tool in this comparison offers a proactive daily brief — they all require you to go looking for information.

Can Relay Digest replace a meeting bot like Otter or Fireflies?

For most use cases, yes. Upload a Zoom recording after the call and Relay Digest processes it identically to a live capture. You lose the real-time live transcript during the meeting, but gain the ability to handle any audio source — phone calls, in-person conversations, voice memos — that a bot can never join.

Is Relay Digest's pricing really that much cheaper?

For teams, yes. A 5-person team pays $15/month with Relay Digest. The same team on Otter.ai Business ($22/user/mo) pays $110/month. On Fireflies Business ($19/seat), $95/month. The savings compound quickly as the team grows — a 10-person team pays $25/month on Relay vs $190–$220 on competitors.

What AI models does Relay Digest use?

OpenAI Whisper for transcription, GPT-4o for Morning Brief, Ask AI, pre-meeting briefs, and the Worry Report, GPT-4o-mini for action item extraction and entity tagging, and OpenAI text-embedding-3-small for semantic search. Teams can supply their own OpenAI or Anthropic API keys. Neither provider trains on API data by default.
