1 What is Prismical, at a glance?
Prismical is a free, open-source AI note-taker from a small Vancouver studio that records meetings, lectures and voice notes and turns them into structured summaries with decisions and action items — without sending a bot into your call.
| Metric | Value | Source |
|---|---|---|
| Maker | amicalhq (Vancouver) | AppSumo |
| Company founded | Feb 2026 | AppSumo |
| License | MIT (open source) | GitHub |
| GitHub stars | 88 | GitHub |
| Platforms | Mac, Win, iOS, Android, Web | prismical.ai |
| Transcription engine | Whisper (local) or cloud | GitHub README |

It comes from the team behind the earlier dictation app Amical, and Prismical itself only reached AppSumo in September 2026 — which is exactly why almost no one has reviewed it yet — the kind of forum-praised hidden gem we go looking for, much like the other self-hostable, privacy-first tools we’ve covered — and why its roadmap still matters.
2 How does the no-bot recording work?
Instead of sending an assistant into your meeting, Prismical listens to your computer’s system audio in the background. If it plays through your speakers, Prismical transcribes it live with speaker labels — and no one on the call sees a third participant.
Recording runs in one of two modes chosen at first launch — local (no account, on-device) or cloud (sync, sharing, managed models) — the same always-on, cloud-hosted AI approach we’ve looked at elsewhere. If you’d rather self-host the whole transcription stack instead, Scriberr is the open-source alternative we tested. Switching modes resets local data, so choose deliberately.
3 Is Prismical actually private?
Mostly yes, with one honest asterisk. Local mode transcribes on your device and stores nothing afterward unless you choose to; cloud mode temporarily retains audio on Prismical’s servers to finalize and recover the note — the usual trade-offs of moving anything to the cloud. Because the code is open-source, both claims are auditable, which you can’t say for the closed rivals — and that it’s auditable at all matters, as one self-hosted app’s security incident showed.
| Capability | Local mode | Cloud mode |
|---|---|---|
| Account required | No | Yes |
| Audio leaves device | No | Temporarily |
| Transcription | Whisper on-device | Local or managed |
| Sync & sharing | No | Yes |
| Speaker labelling | Speaker ID (live) | True diarization |

4 Prismical vs Granola, Otter & Fireflies
Prismical is the only option in its class that is open-source, records without a bot, transcribes on-device, and ships an MCP server — and it is free where the others cost $14-18 per month. The table reflects Prismical’s own comparison, so treat competitor rows as the vendor’s framing.
| Feature | Prismical | Granola | Otter | Fireflies |
|---|---|---|---|---|
| No bot in meetings | Yes | Yes | No | No |
| On-device transcription | Yes | No | No | No |
| Open source | Yes | No | No | No |
| MCP server | Yes | No | No | No |
| Entry price / mo | Free | $14 | $17 | $18 |

5 How much does Prismical cost?
The app is free and open-source; you only pay for cloud transcription hours and AI credits. The cheapest route right now is the AppSumo lifetime deal from $59, and local transcription is unlimited on every tier with a 60-day money-back guarantee.
| Tier | Price | Users | Cloud hrs/mo | AI credits/mo |
|---|---|---|---|---|
| Tier 1 | $59 | 1 | 20 | 100 |
| Tier 2 | $149 | 3 | 60 | 300 |

6 What do early users report?
This review draws on documentation and reports from verified buyers, since the tool is only weeks old and has no long-term track record yet. The early sentiment leans positive: privacy and the no-bot approach win most of the praise, with a short list of rough edges.
“Solid, bot-free notetaking… recording system audio and mic directly from the desktop means no awkward bots joining client calls, and running Whisper locally keeps sensitive conversations private.”
— NXP, verified AppSumo purchaser · source
A university lecturer values local Whisper for keeping “research discussions, student data, or sensitive information” off the cloud, and calls the no-bot approach “a practical and professional advantage” in lectures.

What works
- No bot; records system audio (docs)
- On-device Whisper, open-source & auditable (GitHub)
- Accurate speaker separation in real use (user report)
- One license covers Mac, iPad & iPhone (user report)
What’s still rough
- Can’t save participant names yet (user report)
- No built-in Word/PDF export yet (user report)
- Local Whisper not on Android yet (founder Q&A)
- SOC 2 / HIPAA still an open question (buyer Q&A)
Methodology
This review aggregates verified facts from primary sources rather than a long hands-on test, because Prismical is only weeks old — the same approach we take with other offline-first tool reviews.
- Sources consulted: 7 across the vendor site, GitHub, AppSumo listing and verified buyer reviews
- Data range: product data and user reports from Feb-Sept 2026
- Last verified: September 16, 2026
- Update schedule: re-checked as the product ships roadmap items (participant names, Android local model, export)
- Limitations: no long-term reliability data yet; competitor rows reflect the vendor’s own comparison
Frequently asked questions
Does a bot join my meeting?
No. Prismical records the system audio already playing on your computer, so nothing appears as a participant on the call.
Is Prismical really free?
The open-source app is free forever. You pay only for cloud transcription hours and AI credits; the AppSumo lifetime deal starts at $59, and local transcription is unlimited.
Does my audio leave my device?
In local mode, no — transcription runs on-device with Whisper. In cloud mode, audio is temporarily retained on Prismical’s servers to finalize and recover the note — the kind of permission detail worth scrutinising.
What platforms does it run on?
macOS (Apple silicon and Intel), Windows 10/11, iOS and Android, plus a web app. Local transcription needs macOS 14+ (14.2+ to capture other participants’ system audio).
What is the MCP server for?
It lets AI assistants like ChatGPT, Claude and Gemini read and write your notes, so your meetings become usable context inside those tools.
