Yig product line

Yig is one drafting engine delivered through four products. All four share the same architecture, human-in-the-loop guarantee, and data-stays-in-your-stack posture.

Which product fits which role

Operator role	Primary product	First reach for
Controller	Thinker + Finance	A GL reconciliation draft in the surface already open
FP&A lead	Thinker	Variance commentary in Slack, reviewed inline
Security reviewer	Enterprise	Audit log and reviewer-gate records
IT admin	Enterprise	Topology, surface scoping, reviewer authorisations

Need only drafting? Start with Thinker. Need governance? Enterprise. Bottleneck is data? Add Finance. No infrastructure? The Add-ins.

Yig Thinker — Community and SMB flagship

Yig Thinker is the drafting engine itself. A six-person SMB running their close in Slack does not need the controls a regulated bank needs. They need the agent in the conversation already open.

Forty-plus tools, multi-step planning, native chat integration. Runs in Slack, Teams, Feishu, Excel, and any terminal. Every output passes a reviewer before it ships.

Day 4 of March close, the FP&A lead messages @yig-thinker run variance_review for ACME US Q1 2026 in #fin-close. The draft lands in-thread with three flagged lines. She resolves each and approves.

Use Thinker if your team lives in chat or the CLI.

Yig Enterprise — Governance, SSO, multi-tenant

Yig Enterprise is for organisations whose security team has to inspect what shipped before it ships. SSO, audit trail, role-based reviewer gating, tenant isolation. Annual subscription with a named delivery engineer.

A regulated EU bank’s security reviewer pulls the prior quarter’s audit log, walks each run from invocation to approval, and verifies the model provider against the approved DPA. Every prompt, tool call, and reviewer signature is in the trail.

Use Enterprise if your compliance team needs to inspect every prompt, tool call, and approval before you can deploy.

Yig Finance — Data integration and reconciliation

Yig Finance turns scattered source systems into one consensus the controller can sign. Structured extraction from PDFs and statements, automated reconciliation across ERPs and subledgers. Integrates with Thinker or Enterprise.

Day 2 of close, ACME’s German controller triggers an intercompany reconciliation across SAP, a NetSuite mirror, and a treasury workbook. Finance returns one matched schedule with twelve unmatched lines flagged for judgment.

Use Finance if your bottleneck is data wrangling at month-end rather than drafting.

Office Add-ins — Yig inside Excel, PowerPoint, Word

The Add-ins put the agent in the application without provisioning anything else. Bring-your-own-key, no backend. =YIG() formulas in spreadsheets, drafted slides in PowerPoint, paragraph edits in Word.

Day 8, an analyst preparing the audit committee deck inserts =YIG("draft commentary for variance in row 14") next to the variance schedule. The draft renders in the next cell. She edits the wording before the deck goes to the controller.

Use the Add-ins to try Yig without provisioning infrastructure.

The four products are not four codebases. They are one reasoning core, one audit log, one reviewer gate, in four packagings. The bet is that the same architecture survives a six-person SMB on Slack and a regulated bank on Enterprise on the same day. If it cannot, the product line is wrong — and we will hear about it in audit before we hear about it in sales.
