Generates 3-10 actionable startup ideas filtered by category (B2B SaaS, D2C, marketplace, vertical SaaS, deep tech, agency, creator economy, mobile, hardware), starting budget, funding stance (bootstrap-only / VC-fundable / indie / either), and time horizon (weekend / 30-day / 6-month / multi-year). Each idea ships with one-line pitch, problem, target market with size estimate, revenue model, MVP plan, named competition, first-3-steps to ship, and time-to-first-revenue.
ChatGPT (free + $20/mo) gives ideas but defaults to generic 'AI for X' wrappers and unnamed competitors. Claude ($20/mo) is sharper but still abstract. YC's published Request for Startups list is editorial — high signal but only 20 ideas/year. Free.ai's tool has hard rules baked into the system prompt: no AI wrappers, named real competitors only, no 'major players' filler, fundability-stance match, validation-experiment per idea. 5 ideas in 30 seconds, free.
Yes — Qwen 3 30B on our GPUs. 5 standard ideas (~180 words each) costs about 900 tokens. Free signup gets 10,000 tokens — ~10 sessions. Deep mode (~350 words / idea) and premium models (Claude, GPT-5) cost more but produce VC-grade ideation worth the swap for serious vetting.
10: B2B SaaS, D2C / e-commerce, two-sided Marketplace, Vertical SaaS (industry-specific), Deep tech / AI, Productized Agency / Services, Creator economy (newsletter / podcast / course), Mobile app, Hardware / IoT, plus a "surprise me" mode that picks across all. The category seeds the system prompt with category-specific tradeoffs (e.g., marketplaces flagged for chicken-and-egg liquidity problem).
Four modes: (1) Either — best idea wins regardless. (2) Bootstrap-only — every idea cash-flow positive within 90 days, no fundraising needed. (3) VC-fundable — $100M+ TAM, 10x return potential, defensible moat (Sequoia / a16z bar). (4) Indie / lifestyle — $10-50K MRR target for one-to-three-person team, no investors, no exit. Filters the kinds of ideas the model produces — bootstrap-only skips two-sided marketplaces and deep tech.
Not by default — the "No generic AI for X wrappers" toggle ships on. Hard rule in the system prompt: if AI is core, the idea must justify why this specific application is defensible vs ChatGPT or copy-cat. Toggle off if you actually want AI-wrapper ideas (some still find PMF — Cursor, Perplexity).
No — "Name real competitors" toggle is on by default and the prompt forbids filler like "major players", "incumbents", "established firms". If the model does not know real names, it writes "[research needed: similar tools in this space]" so you can fact-check before pitching the idea.
Adds a "Validation experiment" line to each idea — a $0-200 test that gives evidence in 7 days. Common patterns: landing page + paid traffic, cold outbound to target buyers, manual concierge MVP, fake-door price test. Comes from Lean Startup playbook + Justin Jackson / Indie Hackers community wisdom.
No — both optional. Filling them in dramatically sharpens output. "12yr backend engineer, ex-Stripe" + "deep network in SF construction" produces ideas leveraging both. Empty inputs get more generic suggestions.
No — first session free. Sign up for 10K tokens, generation history, premium models. 10 sessions of standard ideation per signup grant.
Yes — type your skills + constraints in Portuguese, German, Japanese, Hindi, Arabic, etc. and ideas return in the same language with regionally appropriate competitor names where the model can recall them.
Yes — POST to /v1/chat/ with the startup-idea system prompt (in template source). Useful for accelerator cohort tooling, VC scout pipelines, or builder-community newsletter automation. Bearer auth, monthly limits. Docs at /api/.
