Starter Plan · Library Mode
Generate without an API key
Library Mode gives you professional-quality Suno prompts using a smart combinatorial engine — no Anthropic account, no API key, no per-call costs. 300 prompts per month, flat fee.
📚
The combinatorial engine
Library Mode uses a pre-built set of curated data files — genre descriptors, mood profiles, instrument palettes, structural templates, and production tags — to assemble a complete 9-section Suno prompt. No external API call is made. The engine runs entirely on our server, deterministically, based on your inputs.
Input → Engine → Output. Zero AI latency. Instant generation.
💡
Why it still works well
The data behind Library Mode is hand-curated using the same Obiriec quality standards as the AI modules. Genre-specific descriptors, mood-matched exclude lists, instrument combinations, and lyric structure templates are all professionally crafted. The difference from Pro is not quality of craft — it's creative depth and free-text understanding.
Great for genre + mood combinations. Pro handles the edge cases.

1 user seat. Ideal for musicians, songwriters, and Suno users who want consistent, professional prompts at a predictable flat cost.
Each prompt generation (Music Prompt or Surprise Me!) consumes 1 credit. Credits reset on your billing date every 30 days — regardless of whether you're on monthly or annual billing. Annual billing locks the price, it doesn't change how many prompts you get per month. Unused credits do not roll over.

Will Library Mode output the same prompt every time for the same inputs?
Yes — Library Mode uses a deterministic seed derived from the title, genre, and mood you provide. Same inputs = same output. This is by design: you can reproduce any previous generation without needing to save it separately. The Surprise Me! button picks random inputs each time, so the result will always be different.
Is Library Mode output lower quality than Pro?
Library Mode output is well-structured and professionally tagged — the underlying data is curated with the same Obiriec quality standards. The difference is creative range: the AI engine in Pro understands free-text nuances, unusual genre hybrids, and highly specific emotional contexts. Library Mode works very well within genre/mood archetypes. If you're working within known territory (e.g. "Dark Ambient, Melancholic"), the output is excellent. If you need something highly specific or unusual, Pro handles it better.
Do I need to edit the lyrics template before uploading to Suno?
Yes. Library Mode generates a lyrics structure template — it provides the correct section markers, Suno-compatible command syntax, and structural guidance, but the actual lyric lines use placeholder text labeled [Library Mode Template — Personalize before uploading to Suno]. Write your own lines into the structure, or use Pro's Lyric Alchemy wizard to generate complete lyrics with full creative depth.
Can I upgrade from Starter to Pro later?
Yes. You can upgrade at any time from Account Settings. The change takes effect from the next billing cycle. If you upgrade mid-cycle, the remaining days are prorated. You'll need to add an Anthropic API key when switching to Pro — see the
BYOK guide for setup instructions.
Does the launch coupon AMPA30 apply to Starter?
Yes — AMPA30 gives 30% off the first payment on any paid plan including Starter. Valid until June 2026. Apply the code at checkout on the billing page.
What happens if I hit 300 credits before the month ends?
Your generation counter will reach zero and new generations will be blocked until the next billing cycle resets your credits. You can upgrade to Pro for unlimited BYOK generations, or simply wait for the reset. There are currently no top-up packs for the Starter tier.
Do unused credits roll over to the next month?
No. Credits reset every 30 days from your billing date, regardless of how many you used. Annual billing locks the monthly price — it doesn't accumulate unused credits across months.
