Mumble Note
Pros
- + Meeting note type produced a summary, decisions, and action-phrased follow-ups from a 40-minute session, with the transcript one tap away — the rewriting step is the real value
- + Capture friction is the lowest I have used: Apple Watch recording without the phone, screen-locked long recordings, Lock Screen and widget starts
- + To-dos export to Apple Reminders, Google Tasks and Things without retyping; calendar plans can land on Apple or Google Calendar
- + AI chat cites the source notes behind each answer across up to 10 notes/collections, which makes recall trustworthy
- + Starter is cheap — a few dollars a month billed annually — and the free tier covers short notes and quick voice capture
Cons
- - Apple-only: no Android app and no real web client; Mac build is still in open beta
- - Free tier caps notes at 2 minutes, and Starter limits AI chats to 10 a month, so the chat feature is effectively Pro-only
- - 0.x software with visible rough edges — recent changelogs fix missing/duplicated outputs and 'a number of crashes'
- - Pricing surfaces disagree: website shows Starter at $3/month billed annually vs $49.99/year on the App Store (about $4.17/month)
- - Small independent review base (4.8 from 50 App Store ratings at time of writing) and no team/admin offering for shared work
AssemblyAI
Pros
- + Transparent, published rate card: $0.15/hr for Universal-2 and $0.21/hr for Universal-3.5 Pro at time of writing (assemblyai.com/pricing.md), with worked examples showing exactly how add-ons stack
- + $50 in free credits at signup with no credit card required, so I could benchmark real audio before paying anything
- + Guardrails (PII audio/text redaction, profanity filter, content moderation) are first-party add-ons instead of a second vendor contract
- + EU data residency at the same price as US processing — no GDPR surcharge in my review of the rate card
- + Voice Agent API bundles STT + LLM + TTS + turn detection at one $0.075/min rate, which I found cheaper than assembling the same pipeline by hand
Cons
- - No end-user app: everything runs through the API, so non-developers have no path in
- - Streaming bills by open-connection time, not audio sent — an idle socket left open after a call keeps charging in my testing
- - Add-ons stack on the base rate until a 'cheap' transcript approaches $0.40–$0.60/hr for the feature set most teams want
- - Long-file processing is async only; no synchronous option for large uploads
- - Legacy Auto Chapters and Summarization add-ons are deprecated and can fail silently on newer models per the vendor's own pricing reference
