Investment workspace
Build the assumptions. Understand the outcome.
Limited beta. Native Excel equivalence, cloud recovery and independent reviews remain unverified. Results are not approved for investment or lender decisions.
Every investment starts
with its assumptions.
Structure PV, storage and hybrid projects. Trace your inputs through deterministic calculations to versioned results.
- Define your project and application
- Build an explicit set of assumptions
- Calculate, compare and export evidence
Set up the project, then build its financial inputs.
This six-step setup records project context. It does not run the financial model yet; the workbook opens after you save.
Start with the project brief.

Your project drafts and runs appear here.
Project
Saved scenarios · preserve and revisit assumptions
Save the current server draft as an immutable scenario. Loading creates local unsaved inputs; it never replaces a saved scenario or approves a result.
Ask AI · understand project issues
Ask about project gaps or evidence. AI cannot change inputs or grant approval.
AI assistance has not been enabled for this session.
Project readiness · outstanding evidence and scope
Review missing inputs, evidence and release limitations before using a result.
Real project and lender evidence
Prepare requests for the project team and appointed reviewers. Stored files remain unverified until reviewed.
AI synthetic qualification
Run a selected synthetic citation or abstention test against the configured provider. No customer documents are included. A pass does not qualify live projects or enable AI.
Read your project documents
Preview text and citations from PDF or DOCX. Extraction is unverified; scanned pages may need OCR. Original files are not stored by this reader.
Project document checklist
Suggested from saved project setup. Applicability and sufficiency require professional review; references do not verify documents.
Private document room
Store the selected original file separately from reading it. Stored files remain unverified project evidence.
Select a document to check reader availability. AI text sharing requires a separate action.
Inspect your daily workbook
Upload an existing Excel model to review its sheets, input candidates and cached errors before planning the field mapping.
Up to 4,000,000 bytes. Inspection only: formulas and macros are never executed. Cached values can be stale. Nothing is applied to your model, and the original file is not retained.
Review selected source mappings
Choose source candidates after inspection. The server validates the selected mapping against the saved draft; no inputs change during preview.
Bring your project workbook
Download the blank project template, complete the applicable schedules, then review the upload before saving a new draft version.
Download blank Excel template ↓Use the FN Model template. Blank values remain missing. Workbook formulas are not executed. Importing sources does not verify them.
Review proposed import
Full import evidence and proposed inputs
Your financial workbook
Fields follow the selected model’s input structure. Empty values remain missing; the calculation engine checks required inputs and supported values.
Bring back an exported workbook
Only FN-WORKBOOK-1 exports from this model are supported, up to 700,000 bytes. Edit typed input cells and increase the field version for each edit. Keep high precision decimal values as text. Formula cells are not imported as inputs. Save your current draft before previewing.
Full server preview and source evidence
Reimport formula workbook inputs
Supported for the project finance module, up to 700,000 bytes. Save the current draft first. Existing numeric inputs include coverage discount rates and declared debt balances; balances must match selected closing debt. Keep dates, request identities and tranche selections unchanged. Review exact changes and calculation blockers before applying to unsaved inputs.
Full server preview and source evidence
Advanced · edit model JSON
Use numeric strings where required. Apply JSON to update the guided fields. No input values are inferred.
Attach interval evidence
For an imported project workbook, upload a generation, load or price CSV. Datasets are retained as evidence; automatic dispatch binding is not supported.
Download blank CSV headers ↓Required columns: timestamp, duration_minutes, value, unit, source_reference, source_date, classification, version. Include timezone in every timestamp.
Where do these inputs come from?
This source envelope applies to the submitted inputs. Sourced inputs still require verification. Imported project workbooks retain per-input source records in their payload; this envelope describes the submission as a whole.
