For anyone who has to teach what they just learned

From a video you admired to a session you can run.

A recording taught you the subject. Spektree turns it into the material — slides, the words that went with them, a step-by-step guide — then lets you rehearse it out loud and record your own version. In your voice, in your brand, on your machine.

The gap nobody talks about
“I have watched twenty videos on it. I still could not teach it.”

Watching is passive, and it feels like progress right up to the moment someone books you to run the workshop. Then you discover the distance between having understood something and being able to stand up and deliver it: no slides, no structure, no idea what you would actually say for ninety minutes.

So you scrub back through the video with a notepad, pause on every screen, screenshot, re-type, guess at the running order — and rebuild by hand a structure that already exists inside the recording.

Spektree reads it the way you would, only completely: every slide at the end of its animation, the words that were spoken over each one, the session's real chapters, and the step-by-step guide to follow along. Then it hands you a stage to rehearse on.

Trainer notes

What you actually said over each slide: a title, the point, the bullets, and the verbatim to prove it.

  • Attached as speaker notes
  • Graded for faithfulness to the recording
  • Editable before anything is rebuilt

Chapters

The session's real structure, recovered — with the timestamp where each chapter begins.

  • Objective written per chapter
  • Drives the deck, guide and clips
  • Ready to paste as YouTube chapters

The kit

A PowerPoint in four templates, plus every companion document the session deserves.

  • Learner guide, quiz, one-page memo
  • Vertical clips with burned-in captions
  • LinkedIn carousel, article, remaster pack
Measured, not promised

A real 19-minute recording, start to finish

No testimonials yet — Spektree is new. So here is the only proof that means anything: a video I did not make, put through Spektree, with the numbers it reported on the way out. Nineteen minutes of someone else's screen became a 133-slide deck and a guide I could rehearse from the same afternoon.

An English video on ChatGPT Ads, a French deck in under three minutes

A recent 15-minute breakdown of a $4,000 ChatGPT Ads campaign, imported with the output set to French. Nothing cut from the run: the slides captured, the speaker notes written, the deck rebuilt in the Ai4X brand.

Recorded on a Mac in one take. The figures below are the ones this run wrote to its project folder.

01 · CAPTURE

Every slide, fully drawn

Each screen kept at the end of its animation, duplicates and backtracks merged — timestamped back to the moment in the video.

02 · WRITE

Speaker notes, in French

The talk was in English; the notes come out in French — title, key points, transition — with the original verbatim kept underneath to check against.

03 · REBRAND

Your colours, your logo

The deck is rebuilt on your brand kit, with chapter dividers, an outline and a progress bar. A PowerPoint that imports straight into Canva.

Why local matters here

Your client's screen stays on your machine

You demo real systems. Dashboards with real numbers, inboxes, internal tools. That footage has no business being uploaded to a service you cannot audit.

Spektree is an app, not a website. The video is read on your Mac, transcribed on your Mac, and the deliverables are written to a folder in your Documents. The only thing that ever leaves is the slide images and the transcript text sent to Claude to write the notes — and you can see the exact cost of that, per video.

  • No upload of your recording, ever. No account required.
  • Transcription by local Whisper — free, offline, unlimited.
  • Every project is a plain folder of files you own outright.
  • Rehearse against your own slides, or record a cleaner take.
New · Spektree's brother app

Spektree makes the material. Speaktree makes the video.

You taught it; now the recording has to go out. Speaktree transcribes it word by word on your Mac — strike a sentence and the video cut is made. Then it finishes the job.

  • Silences, “um”s and dead air gone in a click
  • Captions, your brand, music composed for the project
  • Vertical clips, YouTube chapters and the post to go with them

Straight answers

Before you ask

Can I use a video that isn't mine?

To study and rehearse from — yes. That is what taking notes on a conference talk has always been, and what comes out lands in a folder on your machine: study material and a rehearsal track for one person.

To deliver to an audience or to sell — no, and Spektree is built so you do not have to. Rehearse until the subject is yours, then record your own take in the studio: your voice, your examples, your slides. What you put your name on should be something you made. Any deck you hand a client should come out of your recording.

Is there a free version?

Yes. Download the app: without a licence it processes the first 20 minutes of any recording you import, and the PowerPoint carries a small "Made with Spektree" line. It never expires.

To judge it on a full session, start the 14-day trial from the app's Settings: everything is unlocked, no card. There is one trial per Mac, and your projects stay yours when it ends.

Is there a Windows version?

Not yet. The code is ready for it and the pipeline is cross-platform, but the installer has to be built on a Windows machine. If you need Windows, say so when you write — it moves up the queue with every request.

Why do I need my own Claude API key?

Because it keeps the price honest. Writing the notes for a one-hour video costs about a dollar; billing you a flat subscription would mean charging the light users for the heavy ones. You pay Anthropic what your videos actually cost, and Spektree shows you the figure per project.

What if the video is just someone talking to camera?

Then Spektree has little to work with, and it will tell you so rather than invent. It reads sessions taught on a screen: software demos, walkthroughs, slide-led workshops. Those are the recordings its thresholds were measured on — and the ones worth rehearsing anyway, because the screen is where the substance is.

Does it work with a three-hour training?

Yes — that length is what it was calibrated on. Long sessions are processed incrementally, so you can pause and resume, and the work already done is never redone.

Can I edit what it produces?

That is the point. Every note is editable, any slide can be dropped, and the deck is regenerated from your corrections without calling the API again. There is also an export pack built for handing the content to Claude Code, Claude Design or any other tool to redesign from scratch.
