Gemini (Google)
The clear pick if your firm runs on Google Workspace — Gemini lives natively in Gmail, Docs, and Sheets. Also strong for very-long-document analysis and Deep Research with citations.
Best for
- Drafting and summarizing inside Gmail and Docs — the side panel pulls thread or document context automatically, no copy-paste
- Long-context analysis on full PDF reports, 10-Ks, or entire prospectus packets — Gemini's very long context window handles documents most other tools cut off on
- Deep Research for multi-source synthesis with inline citations and a research plan you can edit before the report runs. As of 2026 Deep Research can also pull from your own Gmail, Docs, Drive, and Chat — useful for prospect or compliance research that blends public web with internal files.
- Multimodal tasks combining image + chart + text in one pass (e.g., 'explain this chart from a fund factsheet and rewrite the takeaway in plain English for a client')
Avoid
- Voice-sensitive client writing — Gemini reads more bureaucratic than Claude; use Claude for client emails where warmth matters
- M365-centric workflows — if your firm runs on Outlook, Excel, and Word, Copilot's tenant integration wins
- Any client-related work on the consumer free tier — the free tier may use your data for product improvement; only paid/Workspace tiers offer the enterprise data terms
Shortcuts
- Type '@gemini' in a Google Doc or Gmail compose window to drop a request inline without leaving your work
- Deep Research → Edit Research Plan lets you steer what sources Gemini pulls BEFORE it spends ~5 minutes researching — invaluable for keeping the report on-scope
- Workspace side panel → 'Help me write' on a thread auto-grounds in the conversation; on a Sheet it can summarize a range or suggest a formula
- Gems (custom personas) work like ChatGPT's Custom GPTs — set up one for client-email drafting with your firm's voice and disclaimers baked in
Model variants
Gemini 3.1 Pro — the current flagship (May 2026), best for reasoning and long context. Gemini 3.5 Flash (launched 2026-05-19) — fast and cost-effective; beats 3.1 Pro on coding and agentic benchmarks at lower cost. Gemini 3.1 Flash-Lite — high-volume API workloads. The older 2.5 family (Pro, Flash) is still supported for stability. The consumer app routes to the best model per task on paid tiers.
Compliance gotchas
- Consumer Gemini (free or Google One AI Premium) sits OUTSIDE the Workspace data boundary. Even if you pay for Premium, that's a personal subscription with different data terms — never use it for firm data.
- Gemini is now BUNDLED into Google Workspace Business Standard, Plus, and Enterprise tiers (Google dropped the standalone Gemini add-on in 2025). The bundled access inherits your existing Workspace data terms: no training on your prompts or outputs, DLP integration, audit logging, and customer-managed encryption keys available on higher tiers. This is the tier worth paying for in an advisory firm.
- Deep Research and grounded search pull from third-party sites — cited URLs need an extra review pass before you cite them to clients (occasional broken or misattributed sources).
- Workspace Labs features (preview/beta) are NOT covered by the standard Workspace data terms until they GA. Leave them off for any production firm work.

Pricing
Consumer free tier (Gemini app) is not appropriate for firm data. Consumer paid tiers (May 2026): Google AI Plus $7.99/mo, Google AI Pro $19.99/mo (formerly AI Premium — full 3.1 Pro access), Google AI Ultra $99.99/mo (heaviest individual use; cut from $249.99 earlier in 2026). For business: Gemini is BUNDLED in Google Workspace Business Standard ($14/user/mo), Plus ($22/user/mo), or Enterprise (contact sales) — no separate Gemini add-on as of 2025. AI Expanded Access ($20/user/mo) bolts on higher Veo/NotebookLM/Workspace Studio limits for power users. Workspace promotional 50%-off pricing runs on Standard ($7) and Plus ($11) for new customers.
