Finding the right influencer used to take days of manual research. Lillian claims to do it in 5 seconds against a database of 120 million creators, then generate outreach content in 10 seconds — all from a browser sidebar.
The Numbers Behind the Claims
| Metric | Lillian’s Claim |
|---|---|
| Creator database | 120M+ profiles |
| Search speed | 5 seconds |
| Real-time analysis | 8 seconds |
| Brief generation | 10 seconds |
| Reply rate improvement | +68% (proven templates) |
| Average ROI | 1:6.2 |
| Platforms covered | YouTube, Instagram, TikTok |
| Languages | 8 (EN, ZH, JA, DE, PT, VI, ID + more) |
These are self-reported figures from the Lillian website. The ROI of 1:6.2 and the 68% reply rate claim lack third-party verification.
How the Sidebar Workflow Works
Lillian operates as a browser sidebar extension, not a standalone dashboard. The three-step process:
- Search: Enter brand criteria (niche, audience size, engagement thresholds). The AI scans the 120M creator database and returns matches.
- Analyze: For each creator, Lillian runs a "Triple AI Engine" analysis covering audience authenticity, demographics, engagement quality, and fake traffic detection.
- Outreach: Generate a campaign brief and outreach message using proven templates. The tool claims these templates increase creator reply rates by 68%.
The sidebar design means the tool works on any webpage — you can analyze a creator while browsing their Instagram profile directly. Free tools available without signup: YouTube Engagement Rate Calculator, Influencer Brief Generator, Instagram Pricing Calculator, TikTok Pricing Calculator.
Plan Overview
| Plan | Price | Includes |
|---|---|---|
| Free | $0 | 5 questions/day, limited searches |
| Paid | $19.90/mo | Unlimited access, full analytics, brief generation |
| 7-day free trial | $0 | Full features for 7 days |
Lillian positions itself at roughly 1/4 the cost of bundling separate tools. Their own comparison: Claude ($20) + ChatGPT ($20) + DeepSeek ($12) + Amazon AI ($20) = $72/mo vs Lillian at $19.90/mo. Whether this is a fair comparison depends on whether you actually need all four LLM subscriptions.
When Lillian May Not Work
- Fake traffic detection: The website claims detection capability, but user reviews flag it as "inadequate." If detecting fraudulent followers is critical, verify independently.
- Template customization: Limited options. Brands with specific visual guidelines may find the outreach templates too generic.
- Posting schedule rigidity: The tool suggests optimal posting times but offers limited flexibility to adjust for different time zones or audience segments.
- Engagement rate calculation: Noted as "non-nuanced" — may not account for story vs. feed engagement, paid vs. organic reach.
- Low adoption: 523 views, 8 saves. Launched February 2026 with minimal community validation.
- Sidebar dependency: Core features live in a browser sidebar. Users who prefer full-screen dashboards or mobile access may find this limiting.
