## 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

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
