## Heidi

Heidi began as an AI medical scribe and has grown into a broader clinical AI partner for physicians, nurses, allied health staff, and health systems. Its core job is documentation: the app listens to the visit as it happens, writes the note, and keeps working afterwards by drafting referrals, GP letters, care plans, and patient recaps. Every fact it produces is cited back to the clinical record, and nothing is sent to a patient until the clinician has read and approved it.

Beyond note writing, Heidi covers the recurring admin around a clinic day. Morning prep reads the appointment list and briefs the clinician one line per patient in appointment order. Note insights analyse the corrections a clinician keeps making and propose word library entries, auto-edit rules, and template changes. Follow-up digest pulls out every commitment made in the room, matches them to open tasks, and groups them by documented due date. There are also modules for MDT prep, shift handover, results follow-up, and filling PDF or Word forms from the session and patient record.

The vendor says Heidi supports 175M+ patient interactions worldwide and cites its own peer-reviewed safety research on note accuracy across many languages. It is available as a web app plus desktop builds for macOS and Windows that can dictate anywhere on screen and capture telehealth audio directly from the call. Healthcare organisations should evaluate it against local privacy, HIPAA, GDPR, and regional compliance requirements.

**Pricing & Plans:** Freemium. Clinicians can get started on a free tier, and paid subscription plans plus enterprise arrangements for clinics and health systems are available with demo booking. Because healthcare pricing is often seat- or organisation-based, confirm current rates on the official pricing page.

- **Ambient visit transcription:** Listens to the consultation in real time and converts it into a structured clinical note, with an emphasis on accurate drug names and specialty terminology.
- **Automatic note refinement:** Reviews the edits a clinician makes, groups recurring corrections, and proposes word library entries, auto-edit rules, and template changes to approve.
- **Document drafting after the visit:** Writes referral letters, letters back to the GP, care plans, and patient recaps straight from the finished note.
- **Pre-clinic and handover prep:** Builds the day's list, stages meds, allergies and recent results per patient, and drafts ISBAR-style shift handovers.
- **Desktop dictation app:** macOS and Windows builds let clinicians dictate anywhere on screen and capture telehealth audio directly from the call.

**Strengths:** Clinical accuracy is backed by cited, peer-reviewed safety research; Document flow extends well beyond the visit, covering referrals, handovers, recaps, and forms; Desktop app captures telehealth audio and dictates anywhere on screen; Supports many languages for transcription, useful for multilingual clinics

**Limitations:** Pricing is not fully public and typically requires contacting sales; Full value depends on integration with the practice's EHR and templates; Clinicians must still review and approve every output, so it does not remove the review step

## Lemon

Lemon is a desktop AI assistant built around a simple observation: most people speak far faster than they can type. Instead of adding another chat interface, Lemon lives in a small notch at the top of your screen and works at operating-system level, which means it can type into whatever text field you currently have focused — an AI chat window, an email composer, a Slack thread, a CRM note or a document editor.

The core feature is voice-to-prompt. Hold a hotkey, talk through what you actually want — including the messy parts — and Lemon shapes it into a structured prompt with a clear goal, context and constraints. For everyday writing, it also offers straightforward dictation: your exact words appear in a fraction of the typing time, with "ums", repetition and dead ends automatically removed.

Lemon is available for macOS (13 and above) and Windows and is free to start with no credit card required. The company positions it as a speed layer for knowledge work rather than a replacement for AI assistants themselves — you keep using ChatGPT, Claude or Cursor, and Lemon simply gets your intent into them faster and more clearly.

**Pricing & Plans:** Lemon offers a free starting tier with no credit card required, plus paid plans that raise usage limits. Exact plan prices and allowances are listed on the official website.

- **Voice to structured prompt:** Hold a hotkey, speak naturally, and get a well-structured prompt — with goal, context and constraints — typed directly into your active text field.
- **Fast dictation with filler cleanup:** Dictate five times faster than you type while Lemon cleans up filler words and false starts, leaving only your intended words.
- **Writing in every app:** Emails, Slack messages, team updates and notes are rewritten in your tone and matched to the surrounding thread.
- **OS-level, no plugins:** Lemon sits in a notch at the top of your screen on macOS and Windows and works with Claude, ChatGPT, Cursor, Gmail, Slack, Notion, Outlook, Teams and more.
- **Handles messy thinking:** You can ramble, backtrack and change your mind mid-sentence; Lemon still extracts the intent and produces a usable prompt.

**Strengths:** Works system-wide in every app with a text field — no integrations or plugins to configure; Turns rambling spoken thoughts into structured, usable prompts; Dictation mode is markedly faster than typing and automatically removes filler words; Available on both macOS and Windows with a fast two-minute setup

**Limitations:** Requires a consistent microphone setup; noisy environments hurt accuracy; Desktop-only (macOS 13+ and Windows); Free tier usage limits apply, and automated "prompt polishing" removes some manual control
