Q3 Review.docx

Quarterly performance

Marketing spend rose across every paid channel this quarter, with the steepest increases in search and paid social.

Customer acquisition costs increased 23% this quarter despite relatively stable conversion rates.

Retention held at 91% and average order value moved up slightly against the prior period.

Paid search remains the largest single line, followed by social and affiliate.

Blended CAC is now £68, up from £55 in the second quarter.

Affiliate revenue grew 8%, though it remains a small share of the total.

Organic traffic was flat, with no material change in ranking positions.

The team is reviewing channel mix ahead of the Q4 budget cycle.

Customer acquisition costs increased 23%…Explain this
It means the company is spending more to acquire each new customer, even though roughly the same percentage of visitors are converting.

AI-powered text editing

Rewrite any paragraph. Right where you’re working.

Select text in a Windows app, press Ctrl+Shift+Q, and choose Rewrite. Review the AI-generated result, then replace your original text with one click. No switching apps. No copy and paste.

  • Replace selectionPuts the rewrite in place of your text
  • Insert afterKeeps your text and adds the rewrite after it
  • Open in SideNoteOpens the conversation in the main window

In Google Chrome, a paragraph is selected and Ctrl+Shift+Q opens the Selection actions menu. Choosing Rewrite opens the Rewrite window with an improved version, and Replace selection puts it in place of the paragraph. Before: So basically the launch is getting pushed back a bit, because testing took longer than we thought and we found some bugs that need fixing first, but it should hopefully be ready by the end of the month. After: The launch will move back slightly. Testing took longer than expected and found bugs we need to fix first. We hope to be ready by the end of the month.

Illustrative demo. The wording of the rewrite depends on the model you select. Replace selection works where the editor reports its selection, such as Notepad, Word and text boxes in Google Chrome; elsewhere the answer offers Copy.
The workflow

It lives at the edge, not at the centre.

The cost of most AI tools is not the subscription, it is the context switch. Each question means leaving your work, copying context into another window and carrying the answer back. SideNote Pro comes to the application you are in instead, and goes back to the edge of the screen when you are done.

Summon it

Press Ctrl+Shift+Space from anywhere in Windows. No window to find, no tab to load.

Ask

Type, attach a document, capture part of the screen, or act on text you have selected in another application.

Retract it

Press Esc and it folds into a slim leash on the edge of the display, keeping your thread and your place.

Carry on

It is still there when you need it again, at the size and position you left it.

The default shortcut is Ctrl+Shift+Space and can be changed. The panel can float, snap to an edge, stay above other windows, or live in the right-edge drawer. See the Windows sidebar.

Bring your own key

You choose the AI. We provide the Windows workflow.

Bring Your Own Key (BYOK) means you connect SideNote Pro to an AI provider using your own API credentials rather than buying bundled AI usage from us. SideNote Pro ships with no AI credentials of its own: you configure a provider profile, and requests go from your machine straight to the endpoint you set. We do not relay ordinary AI prompts. See how BYOK works in SideNote Pro.

  1. Cloud AI providersConnect OpenAI, OpenRouter, Anthropic, Google Gemini or DeepSeek with your own account: sign in to OpenRouter in your browser, or paste an API key. Each has a preset, and the base URL remains editable.
  2. Ollama or LM StudioPoint it at a local endpoint and inference runs on your own hardware, so that request does not leave the machine.
  3. Any compatible endpointConfigure another OpenAI-compatible service by hand. Compatibility varies between services, so what a given provider supports is worth checking.

Keep several provider profiles and switch between them as the task changes.

Choose a provider

What the licence covers

  • The SideNote Pro Windows application, bought once
  • Every feature, with no tiers
  • No subscription and no account

What it does not cover

  • Hosted provider charges, if your provider bills for requests
  • Credits, tokens or bundled inference of any kind
  • Your provider’s own terms and policies
Local folder context

Point it at a folder and ask.

  1. You choose the folderNothing is discovered, crawled or watched in the background.
  2. Indexing stays localSideNote Pro indexes it on your machine. No AI provider is contacted while indexing, and no embeddings or vector database are involved.
  3. Only excerpts are sentLocal search picks the passages that matter, and only those excerpts go into the request.
  4. Sources stay attachedThe answer keeps a list naming the files, and PDF pages, it drew on, so you can open them.

A large folder never becomes a large prompt.

Useful on a codebase you did not write, a folder of specifications, or research notes spread across a dozen documents.

Model control

Use the model the task actually needs.

The habit that costs the most is running everything through the largest available model. SideNote Pro keeps the choice where you can reach it.

Quick rewrite? Prefer speed.

  • Rewriting a paragraph
  • Summarizing an email
  • Translating ordinary text
  • Ten alternative headings

There is no hidden structure to work out. A smaller model answers just as well, sooner and cheaper.

Hard analysis? Add reasoning.

  • Reviewing a design for failure modes
  • Debugging from logs and code
  • Finding contradictions in requirements
  • Surfacing unstated assumptions

Here the answer depends on connecting several things correctly, and depth earns its cost.

Set the model per provider profile, and optionally send a reasoning effort level where your model supports one. How to choose a model and when depth is worth the wait.

Privacy

Three parties, and what each one sees.

We do not receive your conversations. Your settings, history, folder indexes and usage figures stay on your machine. The AI provider you configured does receive the requests you submit, under its own privacy, retention and billing policies, so choosing a provider you trust is part of using SideNote Pro. The BediniLabs licensing service handles activation and entitlement, not AI prompts.

With a local model, ordinary AI requests can stay on your computer.

Read the privacy architecture
  • No SideNote Pro account
  • No telemetry or product analytics
  • No advertising
  • No SideNote Pro cloud history

AI provider usageHosted charges vary

Not included in the licence, and never will be while SideNote Pro is bring-your-own-key. A hosted provider may charge for what you use under its own pricing. A local model has no API charge.

  • No bundled credits, tokens or inference
  • No markup, because there is nothing in between
  • No API charge if you run a local model
  • Change providers without touching your SideNote Pro licence

Team and volume licensing, the full comparison and the pricing FAQ are on the pricing page. Not sure whether metered API billing suits how you work? BYOK explained covers both sides, and reducing API costs covers keeping it predictable.

FAQ

The questions people ask first.

The rest, on providers, privacy, documents, folders, export and pricing, are on the full FAQ page.

What is SideNote Pro?
SideNote Pro is a docked BYOK AI tool for Windows. Bring Your Own Key (BYOK) means you connect it to an AI provider using your own API credentials rather than buying bundled AI usage from us, so you choose the provider and the model. It can be summoned from anywhere with a global shortcut, kept above other windows, docked to the right edge of the screen, or retracted into a slim drawer leash.
What does BYOK mean?
Bring your own key means the application uses AI credentials you supply, for a provider you chose, rather than bundling AI usage into its own licence. That is how SideNote Pro works as a BYOK assistant: it ships with no AI credentials and no AI endpoint of its own, so requests go from your machine directly to the provider you configure.
Does SideNote Pro include AI usage?
No. The licence covers the Windows application only. Hosted providers may charge for requests under their own pricing and terms; a local model has no API charge.
How much does SideNote Pro cost?
$49, once, for an individual licence covering the Windows application on 2 devices. Team and volume pricing is on the pricing page.
How long is the free trial?
30 days. It starts only after you confirm on the first-use screen, and it is authorized by the licensing service rather than issued locally, so starting it needs an internet connection. The full assistant is available during the trial.
Where are conversations stored?
Locally, in a conversation archive under %LOCALAPPDATA%\SideNote Pro\. History can be disabled, given a retention period, encrypted for your Windows account, or deleted entirely.
Are my conversations uploaded to SideNote Pro servers?
No. There is no SideNote Pro conversation backend, no cloud storage of your threads and no synchronisation. Conversations are stored on your device. The requests you submit go to the AI provider you configured, and that provider applies its own policies.
Which versions of Windows does SideNote Pro support?
SideNote Pro is built for Windows 11 x64 PCs and works across standard Windows 11 editions, including Home, Pro, Enterprise, and Education. On managed business or school devices, administrator policies may restrict installation or certain Windows features.

Your provider. Your models.
Beside your work.
