Sumlion handles the every-cycle busywork for you — making a tedious routine fast, simple, and even enjoyable.
Documents are read locally — only your prompts reach the model, never the files themselves.
Sumlion routes each job to the model that does it best.
Switch interface and output between Simplified Chinese and English at any time.
From the lecture hall to the desk — here's who's putting Sumlion to work.
My students hand in cleaner models. I build the answer key for every case in minutes, then check their work against it.
It runs on the department laptop — no student data leaves the machine, which is the only way our ethics board would sign off.
Preparing a new lecture used to eat a weekend. Now Sumlion drafts the spreadsheet exhibits and I spend the time teaching.
Month-end close is where Sumlion earns its keep — it refreshes the model, the report and the deck together while I review.
It stays on my laptop. For a buy-side shop that's non-negotiable, and it's the reason I could actually adopt it.
The tedious every-cycle busywork is just gone. The heavy tasks go to the model that handles them best.
