Cognera T1(-d)

Bytepersona’s privacy-first mental-wellbeing engine is trained on an ever-growing corpus of 500 GB + of rigorously curated psychological and behavioural-health data. Housed exclusively on our own on-premises servers in Konstanz (Baden-Württemberg), the platform keeps every byte under direct physical control, no cloud hand-offs, no third-party access. The result: ultra-low-latency responses, GDPR-grade data protection, and reliable insights to support your well-being.

No where to be seen.

With privacy in mind

“Privacy is not for sale, and human rights should not be compromised out of fear or greed.” - Pavel DurovAt Bytepersona we live by that principle: your data is yours - period.What that means in practice
• No selling, sharing, or re-using We never monetise your chats or file attachments, nor do we feed them back into our training pipelines.
• No retention without consent By default nothing is stored long-term. You can opt-in (or back out) at any time for
• keeping chat transcripts,
• keeping file attachments,
• or deleting everything immediately after processing.
• GDPR-compliant erasure on demand
If you want your data gone, we invoke a BSI-2011-VS secure-wipe procedure, the method endorsed by Germany’s Federal Office for Information Security. Once finished, you receive a formal deletion certificate documenting time, method, and cryptographic checksums.In short, you remain in full control from upload to final deletion.

Free by default.

Essential - for well-being

Bytepersona is, and will remain fully functional at no cost. Every feature that powers our platform is included in the free tier.To preserve this model for all private users while deterring automated scraping and other abuse, we enforce fair-use rate limits. These ceilings are generous for individual use and are never invoked during normal interaction.If your project or organisation requires heavier throughput (e.g., large-scale analytics, continuous API access, or multi-seat deployments), expanded quotas and priority bandwidth will soon be available through paid plans.

Easy to use.

LibreChat - the easy to use AI interface

Bytepersona is powered by LibreChat—an open-source, ChatGPT-compatible front-end renowned for its clean UI and plug-and-play extensibility. Its modular architecture lets us add bespoke features without sacrificing usability, so if you’ve ever used ChatGPT you’ll feel right at home: same shortcuts, same conversation flow, zero learning curve.

Now on Discord.

About Bytepersona

Bytepersona began as a passion project in Vienna (2024) when Daniel (already captivated by the rise of ChatGPT 3.5-turbo) decided to channel his enthusiasm for applied AI into a real-world tool.
In November 2024 Jessica joined as lead backend engineer and co-owner, accelerating the platform’s technical growth.
Today both founders call Konstanz on Lake Constance (≈ 88 000 inhabitants) home, a region renowned for its quality of life. Early-2025 marked a milestone: the Austrian sole proprietorship Bytepersona e.U. was migrated into a newly registered German company to support our growing international user base.Key dates
• Jan 2024 — Bytepersona prototype launched in Vienna
• Nov 2024 — Jessica joins, becomes co-owner
• Jan 2025 — Move to Konstanz & on-prem infrastructure setup
• Apr 2025 — German entity officially registered
We remain a tight, founder-led team, focused on privacy-centric AI tools and guided by curiosity rather than venture capital.Our team:
Daniel - Founder of Bytepersona, AI Engineer
Jessica - Co-Owner, Backend and AI Engineer
Jonas - AI Engineer, legal team

Our team spans diverse roots. Daniel started in Lower Austria (2nd shape) before settling in Baden-Württemberg, Germany (1st shape). Jessica brings New Zealand heritage (3rd shape) to the mix, while Jonas also calls Baden-Württemberg home. A small world, yet an ambitious team.

    Secure by Design: ISO 27001, Tier III, GDPR

    Infrastructure & localityAll of our infrastructure—including our website, web assets, and Synthara (our AI)—is hosted in Konstanz, Germany, and operated by SeeConnect (Stadtwerke Konstanz). Our workloads run across two geo-redundant data-center sites within the city, ensuring locality, low latency, and operational resilience.Facility and certificationsThe facilities are ISO/IEC 27001–certified and engineered to the Uptime Institute–compatible Tier III design target (concurrently maintainable). In practice, this means key capacity components can be maintained without downtime and distribution paths are redundant.Power & continuityPower is delivered over A and B feeds backed by N+N UPS and diesel generators dimensioned for ~48 hours of autonomous operation, reducing the risk of interruption during grid incidents.Cooling & fire protectionCooling follows an N+1 architecture with cold/hot aisle containment. Early smoke detection (RAS) and a Novec 1230 gas suppression system provide rapid, electronics-safe fire response.Physical security & accessAccess to customer areas is controlled via electronic access systems and CCTV. Visitor access is escorted and limited to assigned areas per the operator’s terms. Network, carrier ecosystem & peeringSeeConnect operates its own fiber backbone and provides direct connectivity to major German and Swiss carriers. The backbone uses WDM, MPLS, and Metro-Ethernet with guaranteed symmetric bandwidth up to 10 Gbit/s, 24/7 NOC monitoring, and SLAs up to 99.9% availability. The Konstanz sites are also integrated with the regional G-FIT backbone that extends to DE-CIX Frankfurt, and host a Rheintal-IX Internet Exchange Point location for local peering.Data protection & sovereigntyBecause all data is processed and stored in Germany, it remains under EU GDPR and German data-protection law jurisdiction. We design and operate on top of an ISMS aligned with ISO/IEC 27001 to enforce risk-based controls, auditability, and continuous improvement.

    GPT-5 by OpenAI

    Bytepersona’s free tier is powered by OpenAI GPT-5, OpenAI’s latest flagship reasoning model. GPT-5 uses a unified system that routes between a fast main model and a deeper “thinking” model, so it replies quickly to simple prompts and spends more time reasoning on harder ones. In practice, that yields more reliable multi-step answers, stronger instruction following, and fewer hallucinations—especially on complex technical and regulatory topics (e.g., GDPR, data privacy, compliance). It’s also OpenAI’s strongest coding collaborator to date, with state-of-the-art results on real-world coding benchmarks and improved tool use for end-to-end tasks. 

    Tech notes

    • Unified/router design: Smart main model + deeper reasoning model; a router picks the right one based on task complexity or explicit cues like “think hard about this.” 
    • Reliability & safety: OpenAI reports substantially lower hallucination rates vs. prior models and reduced sycophancy; the GPT-5 system card details safeguards and the reasoning stack. 
    • Coding performance: SOTA on SWE-bench Verified (74.9%) and Aider Polyglot (88%); improved long-running, tool-heavy “agentic” workflows. 
    • Context window (API): Up to 400k tokens (≈272k input + 128k reasoning/output), with long-context retrieval gains vs. earlier models. 

    Integration made simple

    Bytepersona ingests chat exports from all major messengers: Discord, Telegram, WhatsApp, Facebook Messenger, and beyond- without ever requesting your login credentials.Just drop your exported file (.json, .html, .txt, or any similar format) into the portal and let our parser do the rest. Have logs from a niche or custom app? Import them too... our ingestion engine isn’t limited to mainstream platforms.

    Account Upgrading Information

    Thank you for your interest in considering upgrading to a paid plan from Bytepersona!Currently, our plans are scoped at businesses and authorities, however, you can acquire a paid plan from our Discord Bot if you plan using to use AI-powered tools via Discord.Please note that our Discord Instance and website instance have two separate token limits - they do not transfer!
