PromptPerfect
Pros
- + The automatic optimiser worked on real problems: my structured-extraction prompt went from roughly 60% clean JSON to near-zero errors on a 200-ticket test set
- + Per-target-model optimisation with an Arena view caught a rewrite that helped GPT-4 and hurt Claude — the most useful thing the product did
- + Prompt as a Service anticipated the market: hosted prompt endpoints with quota-based metering and no charge for cancelled/timeout runs
- + Honest, legible metering while it lived: credit costs shown up front, refunds on timeout, credits convertible to API request quotas
- + The /optimizeBatch API (16 prompts per call, iteration control) was a practical tool for teams maintaining prompt libraries
Cons
- - Discontinued: shut down after September 1, 2026 following Jina AI's acquisition by Elastic — the product cannot be used, purchased or migrated from today
- - No successor, export tool, or self-host path was offered; Prompt-as-a-Service endpoints deployed by users are simply gone
- - No evaluation harness even while alive — 'better prompt' was the optimiser's judgement, not a score against your own test data
- - Target model coverage aged quickly, and plan structures churned (credits, daily request quotas, tier reshuffles) in the final year
- - Pricing history is scattered across archives ($9.99/$39.99/$99.99 credit tiers in 2024 versus ~$19/day-quota tiers in 2026 third-party records), making retrospective value comparison unreliable
Notion AI (Writing)
Pros
- + Workspace grounding is the real feature — summaries and answers cited my own sub-pages and database rows accurately in testing
- + AI lives where the work happens: no copy-paste round trips through a chat window, formatting preserved
- + Data handling is documented: no training on customer data without opt-in, subprocessors contractually barred (notion.com/pricing FAQ)
- + Business bundle at $20/member/month annual is close to the old Plus+add-on spend and adds SSO, private teamspaces, 90-day history
- + AI Meeting Notes, AI search and multi-step Notion Agent cover the full loop from capture to draft to action
Cons
- - The $10 AI add-on was retired in May 2025 — AI access now requires Business at $20/member/month minimum for new sign-ups
- - Prose quality trails specialist writing assistants; drafts over-organize into bulleted lists and tone controls move the register less
- - Free and Plus get only a limited allocation of complimentary AI responses that stops mid-workflow when exhausted
- - Custom Agents meter on credits ($10 per 1,000, no rollover, since May 4, 2026) — automation-heavy use is hard to forecast
- - Outside Notion the product has no value; grounded answers wobble in messy, unmaintained workspaces
