Documents

Chat with documents and spreadsheets in plain English.

Document Intelligence

“Your team works across PDFs, Word, slides, Excel, CSVs, scanned invoices, and websites — and every format needs a different tool, a different person, or a VLOOKUP that breaks at midnight. Important answers live in the files you already have. You just need to ask them.”

CostTrail reads every business document your team touches. Upload PDFs, Word, PowerPoint, Excel, CSV, images, or paste a website URL — then ask anything in plain English. Behind the scenes, prose gets indexed for semantic search, spreadsheet rows get loaded into a real SQL engine, and invoice fields get structured automatically — so "sum revenue by region" returns an exact answer like a database, "what does our termination clause say?" returns the cited paragraph, and "show all Salesforce invoices over $5,000" returns clickable invoice cards. Every answer carries its source.

Who uses it?

Real people with real problems this solves.

Finance / Ops Lead

Before: Excel formulas break, pivot tables get stale, "how much did we spend on Sales Cloud last quarter?" needs a manual VLOOKUP across a dozen invoices

With CostTrail: Ask in plain English — real SQL runs on your spreadsheets and line items are read from every invoice

Legal Team

Before: Finding a specific clause across hundreds of contracts takes hours of manual searching

With CostTrail: Ask "what are the termination clauses across all vendor contracts?" and get cited answers in seconds

HR Manager

Before: New hires ask the same policy questions repeatedly — each answer takes 20 minutes

With CostTrail: Upload the handbook once — everyone queries it self-serve with page-level citations

Compliance Officer

Before: Audit prep means reading regulatory documents end-to-end to find the right sections

With CostTrail: Query across all compliance documents simultaneously; answers cite the source page

Operations Lead

Before: SOPs, downtime logs, and shift reports live in separate spreadsheets, PDFs, and folders

With CostTrail: One place to ask — "median downtime per shift in week 14" works on the Excel, "what does the SOP say about lockout?" works on the PDF

How to connect

Upload any file (PDF, Word, PowerPoint, Excel, CSV, text, Markdown, images) or paste a website URL

  1. 1Upload your files — PDF, Word, PowerPoint, Excel/CSV, images, or paste a URL. CostTrail reads each one and figures out its structure.
  2. 2For spreadsheets and CSVs, it builds a real column schema (types, samples, distributions) so questions can be answered with SQL, not guesses.
  3. 3For PDFs and Office files, it extracts text + tables + form fields (invoice number, total, due date) so both prose and field-level questions work.
  4. 4Ask in plain English — every answer is cited (page number, row count, matching documents, or invoice number with a one-click Open button).
  5. 5Open Visual Dashboards on any tabular file for auto-suggested charts, or build your own from a prompt or column picks.

What it replaces

Every feature exists because something was broken before.

Every business file, one tool

Tabs across Excel for spreadsheets, Adobe for PDFs, an OCR tool for invoices, and a search bar that doesn't work

Accepts PDF, Word (.docx/.doc), PowerPoint (.pptx/.ppt), Excel (.xlsx/.xls), CSV, text, Markdown, images (PNG/JPG/WEBP/GIF), and website URLs — all queryable from one chat box

Plain-English Excel formulas

VLOOKUP, SUMIF, COUNTIF, AVERAGEIF, INDEX/MATCH, and pivot tables break when columns move, formulas point to the wrong cell, or someone deletes a row

Ask "sum revenue by region where status is paid" or "average downtime per machine" — runs as real SQL against your spreadsheet rows. No #REF!, no broken references, no rebuild when the data updates

SQL engine for spreadsheets

LLMs hallucinate numbers when forced to total a 50k-row CSV — and bury the wrong answer in confident prose

XLSX and CSV rows are loaded into PostgreSQL with type-classified columns. Aggregations (sum, avg, median, percentiles, stddev) run as SQL — exact numbers, every time

Visual Dashboards

Building charts in Excel takes 20 minutes per chart and nobody shares them

Open any tabular file to see auto-generated charts based on its columns (time series, top-N breakdowns, KPI tiles). Build custom charts from a prompt ("revenue by region") or pick columns directly. Bar, line, pie, KPI, scatter, table — all in the browser

Invoice & form intelligence

Field-level questions on invoices, contracts, and forms force someone to open every PDF

Vision-based extraction reads invoice number, date, total, vendor, line items, due date, tax ID, and more — automatically. "Show all Salesforce invoices over $5,000" returns invoice cards with Open buttons; "how much on Sales Cloud across all invoices" reads line items and totals the matches

Cross-document queries

Answers often span multiple files — manually opening 30 PDFs to compare clauses is a half-day of work

Query across 100+ documents in a single question. The system retrieves only the relevant chunks per file and assembles the answer with per-document citations

Citation-backed answers

AI answers without proof can't be used for legal, compliance, audit, or finance decisions

Every answer includes its source: page number for documents, row count + filters for spreadsheets, invoice number + Open-PDF button for financials. One click to verify

Data quality safety net

A spreadsheet with mixed currency symbols, blank rows, or 30% nulls quietly poisons every aggregate you compute

Ingest detects and reports duplicate rows, empty rows, repeated headers, mixed currency symbols, high null rates, and outliers per column. You see what was cleaned before you trust the answer

Website ingestion

Knowledge bases, documentation sites, and policy portals live on the web — you can't paste a URL into Excel

Paste a URL — CostTrail crawls up to 10 same-domain pages and indexes the content. Documentation becomes queryable without manual export

Saved questions + suggestions

You ask the same 5 questions every Monday and they live in your scratch notes

Star any answer to save it; on first upload, CostTrail suggests 10–30 starter questions based on what the document actually contains

Secure processing

Sensitive contracts and legal documents can't be uploaded to public AI tools

Private Mode keeps PDFs and text on your machine — only relevant snippets and your question reach the AI for the answer

Industries using it

Same tool, different industries.

Legal

Hundreds of contracts per client, each 50+ pages. Finding specific clauses during due diligence or litigation takes hours of manual search.

“What are the termination clauses across all our vendor contracts?”

Healthcare

Clinical protocols, insurance guidelines, compliance documents scattered across folders. Nurses and doctors can't find answers to procedure questions quickly.

“What is the protocol for administering medication X to patients with condition Y?”

Education

Curriculum documents, accreditation handbooks, policy manuals hundreds of pages thick. Teachers re-read them repeatedly to find specific rules.

“What is the procedure for handling student appeals in our grading policy?”

Manufacturing

Technical manuals, equipment documentation, safety SOPs thousands of pages thick. Operators waste time searching PDFs when something goes wrong.

“What are the calibration steps for the CNC machine model X?”

Financial services

Regulatory filings, compliance docs, policy manuals constantly updated. Compliance officers manually verify every change between versions.

“What changed between the 2024 and 2025 AML compliance manual?”

Real estate

Lease agreements, property disclosures, HOA documents. Quick answers about tenant rights or property rules require re-reading full documents.

“What are the pet policies across all rental properties we manage?”
