Synthiz for trainers and teachers

The problem: a course ages faster than anyone updates it

Professional training material has a short useful life. In cybersecurity, employment law, digital marketing or applied AI, a two-year-old deck contains dead examples and sometimes claims that are now simply wrong. Participants notice: they read the same news you did last week.

The update keeps getting postponed, for a straightforward reason. Refreshing a module means redoing the field's reading — recent publications, regulatory changes, this year's conference talks, published case studies — several unpaid days of work, squeezed between two sessions. So three slides get changed and the rest waits.

The second problem is loss. Over a year, a trainer spots a dozen genuinely good teaching examples: a case study inside a podcast, a striking figure in a report, an unusually clear explanation in a conference talk. When it comes time to prepare, not one of them can be found again. You redo the search, or you fall back on the usual example — the 2019 one, served for the twelfth time.

The workflow with Synthiz

1. Create one memoire per module. "GDPR — module 2: processors", "Introduction to neural networks". The base follows the structure of what you teach.
2. Load the foundations. Reference PDFs, regulatory texts, reports, chapters available online. These are the module's stable base.
3. Add the living layer. Conference talks on YouTube, specialist podcasts, recorded case studies: this is where the concrete examples that carry a session live. They come back transcribed, and therefore finally searchable. The Chrome extension captures an open page in one click, and can record the transcript of YouTube videos you watch automatically.
4. Subscribe to the field's sources. A regulator's RSS feed, a professional body's channel, the reference podcast: sync runs on its own — hourly, every six hours or daily — and content arrives already transcribed and summarised. Your monitoring builds without a monitoring session.
5. The useful move at prep time: search instead of redoing. You are preparing a session on a specific point and you know you heard a good illustration somewhere. Search finds the passage from the idea, without requiring the exact wording. From the extension it works mid-read too, in whatever tab you are in: the panel shows the excerpt around the term rather than a list of results to work through.
6. Cross-analyse the sources on a delicate point. The cross-analysis surfaces convergences, tensions and blind spots. A tension between two experts over a concept is often the best starting point for a classroom discussion.
7. Record your teaching thoughts: this explanation worked, this question comes up every session, this example falls flat. Anchored to sources, they become the memory of your practice.
8. Verify before asserting to a room. Timestamped citations take you back to the exact passage. A figure you quoted in class and a participant disputes can be checked on the spot.
9. Export to Markdown or PDF to feed your slides or handouts.

What it changes in practice

Task	Before	With Synthiz
Keeping up with the field	Postponed, done in a rush	Subscriptions processed continuously
One-hour conference talk	Rarely watched	Transcribed and summarised
Finding a good example again	Lost, search redone	Found by meaning, excerpt shown
Annual module update	Several days	The year's corpus already worked through
Sourcing a figure in class	From memory	Dated, verifiable citation

The most direct benefit is financial: prep time is almost never billed. Cutting it improves the real margin on a training day without touching the price.

The honest limits

Synthiz does no instructional design. No learning progression, no objectives, no sequencing, no exercises, no quizzes, no assessment. The instructional engineering work — which is the core of the job — remains entirely yours.

It is not a materials production tool. No slide generation, no layout, no templates, no brand styling. You export to Markdown or PDF and build the deck elsewhere.

No LMS features. No delivery to learners, no progress tracking, no attendance, no accreditation compliance, no Moodle, Canvas or 360Learning integration. Synthiz works upstream, on your material.

Nothing shared. No base common to a teaching team, no co-built module, no training-provider library. Two trainers on the same module share nothing.

No content validation. The tool does not tell a reliable source from a sloppy blog post, nor a regulation in force from a repealed version. In regulated fields — law, health, safety — that verification is entirely on you, and the stakes are real: a trainer teaching a rule that no longer applies carries the liability.

Summaries contain approximations. They are produced by language models. Nothing asserted to a room should come out of a summary without passing through the original citation.

Nothing for delivery. No in-room interaction tools, no polling, no group management. What happens during the session is outside this tool's scope.
