Which one should you ship with? Here is the side-by-side panel verdict, pricing read, reviewer split, and community vote comparison.

Bibby AI is an AI-first LaTeX editor that reimagines the entire research paper writing workflow. Where Overleaf gave researchers cloud-based LaTeX compilation, Bibby embeds AI throughout: it searches 200+ million academic papers for citations, inserts perfectly formatted BibTeX in one click, drafts equations from natural language, generates abstracts and literature reviews automatically, and runs an AI paper reviewer before submission. The Equation from Image feature stands out — snap a photo of a handwritten equation and Bibby converts it to valid LaTeX code. Combined with 5,000+ journal-specific templates and real-time syntax error detection, the tool significantly reduces the friction of the LaTeX learning curve for early-career researchers. Real-time collaboration with unlimited co-authors and GitHub two-way sync round out the feature set. Critically, Bibby processes everything on its own secure servers without routing data through OpenAI, Google, or other external AI providers — a meaningful privacy guarantee for researchers working with unpublished findings. A published arXiv paper (February 2026) and Product Hunt listing signal this is a credible product with academic traction. At $0 free tier and $8-20/month Pro, it undercuts Overleaf's institutional pricing substantially.

OpenMythos is a PyTorch reconstruction of the suspected architecture underlying Anthropic's Claude Mythos model, built entirely from published research. Creator Kye Gomez hypothesizes that Mythos uses a Recurrent-Depth Transformer (RDT) — where a subset of transformer layers loops multiple times per forward pass with shared weights rather than stacking unique layers. This allows the model to simulate "thinking" by iterating over the same compute graph, giving it emergent chain-of-thought behavior without explicit CoT prompting. At 770M parameters, the OpenMythos implementation reportedly matches the downstream quality of a 1.3B standard transformer on benchmarks. The architecture combines Multi-Latent Attention for memory compression, LTI (Linear Time-Invariant) stability constraints to prevent training instability during recurrence, Mixture of Experts routing for specialization, and Adaptive Computation Time (ACT) halting to decide when to stop looping per token. The project exploded on GitHub within days — 6.2k stars, 1.2k forks — and Kye's X announcement drove massive engagement (4.1k likes, 4.5k reposts). Community reaction is genuinely divided: AI researchers calling it "the most sophisticated reverse-engineering of an LLM architecture I've seen" while Anthropic has not confirmed or denied any of the architectural claims. This is an educated speculation backed by real engineering, not a marketing exercise.
Reviewer scorecard
“The GitHub two-way sync is the feature I've been waiting for in a LaTeX editor. Being able to commit paper revisions through Git while co-authors use the web UI is a workflow that Overleaf can't match. The API privacy guarantee is also important for projects under NDA.”
“Whether or not Anthropic actually uses this architecture, the RDT implementation itself is genuinely impressive engineering. The ACT halting mechanism and LTI stability constraints are clever solutions to problems anyone trying to build reasoning models will face. Fork-worthy regardless of the Mythos speculation.”
“200M paper search sounds impressive until you realize Semantic Scholar and Google Scholar cover the same ground for free. The AI-generated literature review is prone to hallucinating citations in a domain where accuracy is career-critical. Overleaf's institutional integrations and compliance certifications still win for university procurement.”
“This is reverse engineering based on vibes and published papers, not leaked weights or verified architecture docs. Anthropic hasn't confirmed a thing. The 770M benchmark comparisons are cherrypicked and the '1.3B equivalent quality' claim needs independent reproduction. Intellectually interesting, empirically unverified.”
“Academic publishing workflows haven't changed since LaTeX was invented — Bibby is one of the first serious attempts to modernize the entire loop from research to submission. If citation accuracy improves and institutional adoption follows, this could become the default writing environment for the next generation of researchers.”
“Regardless of whether Mythos actually is an RDT, this project demonstrates that open-source researchers can meaningfully reconstruct competitive reasoning architectures from scratch. That capability gap between frontier labs and open-source is closing faster than most realize.”
“Equation from Image is the kind of feature that makes non-LaTeX users suddenly want to use LaTeX. The journal template library alone saves hours of formatting headaches. For anyone writing technical documentation or whitepapers, this is a genuine step up from Word or Google Docs.”
“A 6.2k star project in two days means something hit a nerve. The documentation is excellent — clear architecture diagrams, detailed training notes, working code. Even if the Mythos speculation is wrong, this is a model for how to share research engineering properly.”
