SunuXel

What it does

Hand it the whole task. Not just the question.

Most assistants answer. SunuXel opens the files, runs the code, checks its own work and hands back something you can use. Here is what that looks like on six tasks that usually eat a full day.

SunuXel is in early access, open by invitation. These conversations are examples of the work it is built for, with sample files. They are not customer stories.

A payment bug nobody could reproduce

You

Since Tuesday's deploy, about 1 checkout in 40 fails with “amount mismatch”. We can't reproduce it. Repo and the last 2,000 log lines attached. Find it and fix it.

  • checkout-service (repository)
  • payments.log, 2,000 lines

What it did

  1. LogsGrouped the 51 failures: every one is in KWD, BHD or OMR.
  2. CodeThose currencies use 3 decimals. Tuesday's commit rounds every amount to 2.
  3. TerminalWrote a test that fails with 12.345 KWD, then fixed roundAmount().
  4. TerminalFull test suite: 214 passing. Opened a pull request.

SunuXel

Found it. The failures are not random: they are every order paid in Kuwaiti dinar, Bahraini dinar or Omani rial. Those currencies have three decimal places, and Tuesday's change rounds all amounts to two. The processor receives 12.35 when the cart says 12.345, so it rejects the charge.

The fix reads the number of decimals from the currency code instead of assuming two. I added a test for each three-decimal currency so this cannot come back silently.

The 38-page contract you sign on Friday

You

We sign this vendor agreement on Friday. 38 pages. Tell me what will hurt us, and draft the changes we should ask for.

  • vendor-agreement-v4.pdf, 38 pages

What it did

  1. ReadingRead all 38 pages and the two annexes, clause by clause.
  2. AnalysisChecked renewal, liability, pricing, data and exit terms.
  3. WritingDrafted replacement wording and a short email to the vendor.

SunuXel

Four clauses deserve a fight before Friday. Section 14.2 renews the contract for 36 months unless you cancel 120 days before the end, and the cancellation must go by registered mail. Section 9.4 caps their liability at three months of fees, and that cap also covers a data breach on their side. Annex B lets them raise prices once a year with no ceiling. Section 18 puts any dispute under a court in a country where neither of you operates.

I wrote replacement wording for each one: 12-month renewals with 30 days' notice by email, a separate higher cap for data breaches, increases limited to inflation, and your home courts. The email to the vendor is ready to send.

Data

Signups up, revenue flat. Why?

You

18 months of subscription exports. Signups keep growing but monthly revenue hasn't moved since spring. Find out why, with proof, and tell me what to change.

  • subscriptions-export.csv, 41,880 rows
  • plans.csv

What it did

  1. PythonCleaned the export and rebuilt revenue month by month.
  2. PythonSplit every customer by signup month and by discount code.
  3. ChartsDrew retention curves for each group.

SunuXel

Growth is real, but one group cancels it out. Customers who joined with the SPRING50 code leave fast: 61% are gone after their third month, against 22% for everyone else. They are 38% of your new signups since March, so each month they bring in as much revenue as they take away when they leave.

Stopping the code would not fix it alone. These customers mostly picked the monthly plan. Offering the discount only on annual plans keeps the acquisition and removes the churn. I can simulate the next six months both ways.

A 52-minute interview, cut for social

You

Turn this 52-minute interview into vertical clips for TikTok and Reels. Subtitles in English and French. Only the moments that actually hold attention.

  • interview-final.mp4, 52 min

What it did

  1. TranscriptionTranscribed the whole interview with timestamps.
  2. SelectionPicked 7 self-contained moments of 25 to 45 seconds.
  3. EditingReframed to 9:16 on the speaker and burned in both subtitle tracks.

SunuXel

Seven clips. I kept the moments that make sense without the rest of the interview and start with a claim or a question in the first two seconds. I dropped the introduction and the sponsor segment.

Each clip comes in two versions, English and French subtitles, with a cover image and a caption proposal. Clip 4, about the first year without salary, is the strongest opener.

The Monday report nobody wants to build

You

Every Monday before 9 a.m.: pull last week's numbers from our three dashboards, update the board deck, and send it to the leadership team. Ask me before sending the first one.

What it did

  1. BrowserSigned in to the sales, support and product dashboards with read access.
  2. SlidesUpdated the 9 charts and the summary slide of the board deck.
  3. ScheduleSet the task to run every Monday at 7:30 a.m.
  4. ApprovalWaiting for your go-ahead before the first email.

SunuXel

The deck for this week is ready. Two things changed enough to mention on the first slide: support tickets rose after Thursday's release, and the trial-to-paid rate dropped on mobile.

From next Monday I will do this alone at 7:30 a.m. and send it at 8:45. If a number moves by more than 20%, I will flag it in the email instead of burying it on slide 7. Approve this first send?

Delivered · Board deck, every Monday at 8:45 a.m.

From an idea to a live page in one afternoon

You

I want to test demand for a paid newsletter on African tech before building anything. Make a landing page with signup, pricing and a payment test, and put it online.

What it did

  1. WritingWrote the page: promise, sample issue, pricing, FAQ.
  2. CodeBuilt the page and the signup form, tested on 6 screen sizes.
  3. PaymentsConnected a test checkout so you can measure intent to pay.
  4. DeployPublished it and sent you the link and the analytics view.

SunuXel

The page is live. Visitors can join the free list or pay for the annual plan. Payments are in test mode, so nobody is charged, but you will see exactly how many people tried to pay.

Run it for two weeks before deciding. If fewer than 2% of visitors reach the payment step, the offer or the price needs work before the product does.

How it works on a task

It shows its work

Every file read, command run and test passed appears in the conversation, so you can check how an answer was reached.

It asks before it matters

Sending an email, paying, deleting or publishing waits for your approval. You decide what it may do alone.

It works in its own computer

Code runs in a sandbox that is created for the task and deleted after it, away from your machine and your accounts.

It checks its own result

Code gets tests, numbers get recomputed, and when it is not sure, it says so instead of guessing.
