What's new in Optivise

A running log of what we've shipped — new capabilities, improvements, and fixes for Optivise and the Excel add-in.

v0.10.10

Formula Trace: see exactly how any formula works

Select any formula cell in the Excel add-in and open Formula Trace — every input is color-coded, clickable, and shown with its live value, next to a plain-English explanation of what the formula actually does. Lookups show the exact row they matched, and you can ask follow-up questions right in the panel.

  • NewTrace any formula: every input color-highlighted on the sheet, clickable, with live values
  • NewA plain-English explanation of each formula, and an Ask box for follow-up questions
  • NewVLOOKUP and INDEX+MATCH show exactly which row they matched and what they returned
  • NewAudit flags catch hardcoded numbers, blank inputs, and cross-sheet links — and walk an error back to its source
  • NewDrill into nested formulas in place, or follow them level by level
  • ImprovedThe trace stays live — edit an input and the panel refreshes in place
  • NewSign in to the add-in through your web browser with a one-time code
  • FixedVery large data imports could occasionally land in the sheet as a single corrupted row
v0.10.9

Pick a model per chat, and a cleaner approval step

  • NewSet your preferred default model and effort in Settings
  • ImprovedA cleaner, clearer approval card when the assistant asks before changing your sheet
  • ImprovedMore refined model and settings controls
v0.10.8

Long, complex jobs that don't drop

The Excel add-in now handles long-running requests far more gracefully — it keeps going through interruptions, recovers on its own, and lets you pick a run back up if it stops. Reviewing what changed is clearer too.

  • ImprovedLong agent runs no longer time out or get cut off partway through
  • NewIf a run is interrupted, you can resume it instead of starting over
  • ImprovedSee exactly what the assistant changed, laid out clearly

v0.10.7

A clearer view of what the assistant is doing

  • ImprovedA redesigned activity view that honestly shows each step the assistant takes
  • ImprovedConversations can run longer without losing track of earlier context
  • FixedError messages are now clear and readable instead of raw technical text

v0.10.6

The assistant can see your Excel sheet

Your assistant can now take a visual look at your spreadsheet — reading charts, layout, and formatting the way you see them — so it understands far more than the raw cell values. We also tidied up how you manage chats and your account.

  • NewThe assistant can visually read your Excel sheet, including charts and formatting
  • ImprovedChat deletion and sign-out are now grouped sensibly under your account
  • FixedThe context indicator's tooltip now matches your light or dark theme

  • NewFriendly, branded error and page-not-found screens
  • FixedButtons on the landing page that used to do nothing now work

  • ImprovedIn-app notifications replace abrupt browser pop-up alerts
  • FixedA leftover tool-call placeholder no longer appears in your chat
