Backplain vs Glean: what's actually different.
Glean is enterprise search and an AI assistant across your connected apps. Backplain sits next to it: the same prompt across up to 10 frontier models, side by side, behind a patent-pending AI Firewall — for one flat $129/seat/mo.
| Glean | Backplain Business | |
|---|---|---|
| Per seat / month | ~$40–$50 at scale (sales-quoted; not publicly listed — per RetrieveIt.AI, 2026) | $129 — flat, listed |
| Annual cost (10 seats) | Not typical — buyers report 100+ seat minimums; ~$60K–$100K+/yr at entry | $15,480 |
| Minimum commitment | Annual contract, sales-assisted; pooled-credit overage on Enterprise Flex | 10 seats — monthly or annual |
| Model coverage | Glean's curated assistant on top of major frontier models — vendor-managed | 47 models across 9 providers |
| Multi-model comparison | Single assistant, single answer | Up to 10 models side by side in one prompt |
| AI Firewall | — | Yes (patent-pending) — PII redaction before any model sees the prompt |
| Custom PII filtering | Connector-level permissions; no prompt-time PII firewall | Yes — at the prompt boundary, before any model sees data |
| Prompt-level audit logs | Workspace-level admin logs | Every prompt, every session, from seat one |
| Hosting flexibility | Glean-hosted SaaS (with private deployment options at the top tier) | SaaS → BYO cloud → bare metal |
| Compliance posture | SOC 2 Type II; ISO 27001; HIPAA BAA available; not FedRAMP-listed | SOC 2 Type II in progress (target Q3 2026); HIPAA BAA available on Enterprise; NIST 800-53 / 800-171 (CMMC L2 baseline) controls mapped; FedRAMP pursuing — not yet listed on the Marketplace |
| Best fit | Teams that need federated search across 100+ connected apps | Teams that want vendor-agnostic comparison and a hard PII boundary at one flat seat price |
Glean is genuinely good at one thing: searching across the long list of SaaS apps your company already uses — Slack, Drive, Notion, Confluence, Jira, Salesforce, Zendesk, and dozens more — and surfacing answers grounded in that internal corpus. If your top problem is "we can't find anything across our tools," Glean is the right shape of product.
Backplain is solving a different problem. The core workflow is the one we offer everywhere else on this site: take a single prompt and run it across up to 10 models simultaneously — GPT-5.x, Claude Sonnet/Opus, Gemini 2.5, Llama 4, Mistral, and others — then compare the answers in one view. For teams already on Glean, that turns Backplain into a second-opinion engine: get Glean's grounded answer, then drop the same question into Backplain to see how three frontier models from different vendors handle it without the connector context biasing the response.
The other half is the AI Firewall. Every prompt that leaves Backplain passes through a patent-pending software-layer firewall with custom PII redaction before any model sees it — a different control point than connector-level permissions. Combined with prompt-level audit logs from seat one, a 10-seat starting point, and a flat $129/seat/mo with no token meter, Backplain fits cleanly alongside Glean for teams that want vendor-agnostic comparison and a hard compliance boundary, without giving up the internal search workflow.
Pricing source: Glean does not publish seat pricing. Buyer-reported figures of ~$40–$50/seat/month at scale come from RetrieveIt.AI, Glean Pricing: What It Actually Costs in 2026, retrieveit.ai. Glean's own Enterprise Flex documentation confirms a per-user license with pooled pay-per-use credits for advanced AI features (help.glean.com).
