Use ordinary search
Straightforward queries remain straightforward. Perspective tools appear only when they add value.
Peiron
A planned, user-funded search engine that keeps sources visible and makes substantive disagreement easier to inspect.
- Category
- Platforms & Utilities
- Platform
- iPhone + Safari
- Status
- Starting development
Search the web without surrendering the frame.
Conventional results come first. When a query contains meaningful disagreement, Peiron can add an optional source-grounded map of materially different arguments without imposing a default AI conclusion.
User value
Sources first. Perspective when useful.
Find relevant results quickly, then inspect how serious arguments differ.
Inspect the evidence
Every visible argument stays connected to sources the user can open and assess.
Keep editorial agency
Peiron maps disagreement without turning one model-generated synthesis into the destination.
Features
The planned first experience.
A focused search product for finding sources and exploring meaningful disagreement.
- 01
Conventional results
Retrieve, normalize, deduplicate, and rank useful web results with direct source access.
- 02
Search lenses
Focus a query on the web, news, forums, recent material, or primary sources.
- 03
Perspective overview
See materially different claims, assumptions, explanations, priorities, or proposed actions.
- 04
Missing-perspective search
Ask what the initial result pool may be missing through a bounded follow-up retrieval.
- 05
Ranking explanations
Inspect the material factors that helped a result appear.
- 06
Explicit source controls
Block or favor domains through reversible local preferences rather than inferred ideology.
How it works
From query to evidence.
The shortest useful path remains available at every step.
- 01
Ask
Enter a query and, when useful, choose a search lens.
- 02
Find
Receive conventional, source-oriented results before slower analysis completes.
- 03
Compare
Open a perspective overview when the evidence supports meaningful disagreement.
- 04
Inspect
Move from an argument to representative sources and the evidence beneath it.
- 05
Decide
Refine, search for missing coverage, open a source, share it, or leave.
Product concept
Arguments, not tribes.
A perspective is defined by what it argues about this query, not by a permanent label attached to its publisher.
Query-relative
The same source can contribute differently depending on the question and the evidence it presents.
Relevance before diversity
Different does not mean useful. Weak material is not promoted to manufacture balance.
AI remains subordinate
Models may help extract and group arguments, but sources remain visible and abstention remains valid.
Architecture
One service, replaceable providers.
This is the frozen target architecture for implementation, not a deployed system.
- 01iPhone app or Safari extension
- 02Versioned Peiron API
- 03Bounded retrieval adapters
- 04Normalization and ranking
- 05Optional perspective processing
- 06Progressive source-oriented response
Modular monolith
Clear internal modules keep deployment manageable while preserving system boundaries.
Provider-independent
Search and model vendors sit behind replaceable adapters rather than defining the product.
Graceful reduction
Conventional search should remain usable if AI processing or one retrieval provider fails.
Technology
A planned, replaceable stack.

Development
Definition complete. Engineering next.
Phase 0 established and froze the product, experience, perspective model, privacy boundary, target architecture, economics, and validation strategy. No executable product exists yet.
- Stage
- Starting development
- Current milestone
- Phase 0 complete
- Implementation
- Not started
- Product media
- Not available
Completed definition work
- Thirty-four authoritative product and system definitions
- Nine recorded definition batches with an integrity-checked archive trail
- Frozen user experience, perspective model, privacy boundary, and first-release scope
- Target architecture, data model, API contract, security model, and test strategy
- Development plan and chronological journal for the transition into engineering
Next phase
Create the reproducible engineering foundation, then prove conventional retrieval, normalization, deduplication, ranking, and cost measurement before adding the perspective layer.
